Happy Halloween! Audit Statuses of Canadian Cryptocurrency Exchanges

Halloween is a wonderful time of year!
Businesses and consumers alike dress up, children go door to door naively asking strangers for candy, and everyone parties celebrating things like death and evil.
In the spirit of Halloween storytelling, let me tell you a scary story.
There once was a Canadian cryptocurrency exchange. It had one of the simplest user interfaces, the CEO was well known in person and trusted throughout the country for over half a decade, and it had several deposit and withdrawal methods. It was the first to register as a money services business and for much of its history, it was one of the most legally compliant exchanges. It even looked to be headed for public listing on the TSX. The exchange operated for 6 years, assuring users that all funds “are stored in cold storage, using some of the most secure cryptographic procedures possible.” Unfortunately, while we celebrate Halloween by dressing up and wearing masks once a year, the wonderful people who brought us this exchange played “dress up” for over half a decade and time will only tell if there are any more “masks” to come off in this story.
There’s no better or more fitting time to explore one of the darkest realities of the Canadian cryptocurrency space - exactly what is backing any of the cryptocurrency on Canadian exchanges. It’s easy to lose sight that there are real people behind these funds. Most people spend most waking hours working for their money. It literally is their lives. Impacts to victims are not just financial, but psychological and social as well. Victims of exchange fraud go through depression, anxiety, and trauma. They lose their trust and faith in humanity. They withdraw from friends and family in shame and humility.
In the spirit of exploring dark and evil things, let’s examine exactly what evidence there is that any of your crypto is backed on any Canadian exchange. This is a continuation of research I’ve been working on since May/June. I hope it will be enlightening and help you better protect your funds that you worked hard for.

I’ve done a detailed analysis of all Canadian exchanges I could find that handle any sort of custody of funds, and grouped them into 3 categories:

Non-Audited Exchanges (“trust us, we haven't spent your money, we promise")

Bitvo - The service “utilizes a proprietary cold storage solution”. Proprietary, as in, definitely better than established non-proprietary solutions. If you can’t withdraw, they “will credit your account for [their] withdrawal fee”. They’re not an MSB that I could find, nor are they audited.
Coinfield - MSB. No audit. Luckily it’s the "most secure trading platform in Canada" - though apparently not the other 150+ countries, including Estonia where they’re based. No matter which country you pick, the “Security” page still says "most secure trading platform in Canada".
Coinsmart - MSB. Not sure what "[i]ndustry leading cold storage" is, but luckily they’re so "accountable to [their] clients, community and to each other" and "committed to being open and honest" that they don’t need any audit.
Coinut - MSB. Also "the most secure cryptocurrency exchange platform". In addition to not using multi-sig and "not us[ing] USB drives, as the online computer may be infected with virus", they also don’t use audits.
Einstein - You can get “your money deposited and withdrawn faster than any other exchange”. As one customer said "With so many hacks and exit scams, it gives me confidence knowing Einstein is backed by hard-working people just like me." Just check the user experience on their subreddit from their "220,000+ satisfied customers".
EZ-BTC - As they said, “All your coins are kept in cold storage. They’re safe.” They have “strong security”. The supposed presence of physical ATMs was one of the strategies to build customer confidence and they promised 9% annual return on stored funds.
NDAX - MSB. Luckily also “Canada’s most secure trading platform” with "fast withdrawals". I couldn’t find any audit but at least there’s a full page risk disclosure and disclaimer. You can sleep peacefully knowing that they’re legally protected.
Netcoins - MSB. The best assurance I could find of solvency is that they “can process large transactions”. Although they don’t waste time with audits or links at the bottom of their website, apparently “[a]ll transactions happen quickly and securely” “within the same day”.
Newton - MSB. “No-fees”! Your funds are stored in the "professional custody" of Balance, which doesn’t appear to be a registered MSB. I couldn't find any audit of the funds but they "audit [their] policies and controls". They "publish the reports", but I couldn't find any reports. Simply storing funds somewhere else doesn’t give any assurance they cover customer balances.
QuadrigaCX - Operated since 2013, with “vast cryptocurrency reserves” right up to the end. "Bitcoins that are funded in QuadrigaCX are stored in cold storage, using some of the most secure cryptographic procedures possible." Their "cryptographic" procedures are so secure that nobody can access any funds, even now!
Shakepay - MSB. Many will trust the raccoon mascot promising “commission-free” trading. No audit found but the “majority of all digital assets on Shakepay are stored securely offline”. Whatever this means, it’s good to know that up to half might not be.

Audited Exchanges ("so and so swears we didn't spend your money, you can trust them, we showed them once before")

Bitbuy - MSB
Coinberry - MSB
Coinsquare - MSB
Kraken - Not a registered MSB in Canada (that I could find)

Proof of Reserves ("here's your money, right here right now on the blockchain, and here's a proof that we included your balance in that total")

Rather than depend on outdated audits (or lack thereof), it’s actually possible to use the blockchain and cryptography to enable a public real-time audit. This can give assurance to every customer that their balances are fully backed. Giving everyone the ability to check the integrity of balances will keep us all safer. It immediately exposes any fraud, and in most major hacking cases there was advanced hacking that went unnoticed ranging from months (Bitgrail), or years (Mt. Gox). Having an aware public reduces the number of people trading on fraudulent exchanges, and can pressure the exchange to shut down trading or resolve the hack faster, so less funds are permanently lost.
To help explain exactly what this is and how it works, I’ve started a detailed tutorial. I did not come up with this algorithm - it was created in 2014 by a guy named Gregory Maxwell. Sometimes cryptography can be hard to understand. Hopefully this tutorial is simple:

< < Take Our Proof of Reserves Tutorial > >


Given what can often be at stake, I had hoped that maybe one of the “audited” exchanges might embrace Proof of Reserves. Sadly I haven’t had any such luck.
Bitbuy:
Coinberry:
Kraken:
As such, the bottom line is that present exchanges don’t want to share public keys and offer the kind of transparency which is necessary to enable customers to know their funds are backed. Attempting to get answers doesn’t reveal them, and I’m left with an unnerving silence not unlike the end of Halloween night, like I’m asking questions nobody should ask.

Having spent the last 8 months of my life watching and being part of a large group of people suffer through a grueling bankruptcy, where we’ll be “lucky” to only lose 90% of our funds, I want this fixed. I don’t want to live in a reality where fraud can happen just buying/selling on the largest and most trusted exchanges. Especially now that I’ve learned blockchain provides the capability for even greater transparency and a level of public audit far beyond even what's possible with fiat.
If you feel the same way, I invite you to join Quadriga Initiative, where we are fighting for a Proof of Reserves future and also enabling businesses to help Quadriga victims with an innovative token recovery project. Every sign-up helps us reach our goal and launch the project!

If any information in this post is incorrect, please let me know so I can fix it! Thanks! I’m happy to update the audit status of any exchange given reasonable evidence, or provide a review of any other custodial exchange I might have missed.

⚡ Lightning FAQs ⚡

If you can answer please PM me and include source if possible. Feel free to help keep these answers up to date and as brief but correct as possible
Is Lightning Bitcoin?
Yes. You pick a peer and after some setup, create a bitcoin transaction to fund the lightning channel; it’ll then take another transaction to close it and release your funds. You and your peer always hold a bitcoin transaction to get your funds whenever you want: just broadcast to the blockchain like normal. In other words, you and your peer create a shared account, and then use Lightning to securely negotiate who gets how much from that shared account, without waiting for the bitcoin blockchain.
Is the Lightning Network open source?
Yes, Lightning is open source. Anyone can review the code (in the same way as the bitcoin code)
Who owns and controls the Lightning Network?
Similar to the bitcoin network, no one will ever own or control the Lightning Network. The code is open source and free for anyone to download and review. Anyone can run a node and be part of the network.
I’ve heard that Lightning transactions are happening “off-chain”…Does that mean that my bitcoin will be removed from the blockchain?
No, your bitcoin will never leave the blockchain. Instead your bitcoin will be held in a multi-signature address as long as your channel stays open. When the channel is closed; the final transaction will be added to the blockchain. “Off-chain” is not a perfect term, but it is used due to the fact that the transfer of ownership is no longer reflected on the blockchain until the channel is closed.
Do I need a constant connection to run a lightning node?
Not necessarily,
Example: A and B have a channel. 1 BTC each. A sends B 0.5 BTC. B sends back 0.25 BTC. Balance should be A = 0.75, B = 1.25. If A gets disconnected, B can publish the first Tx where the balance was A = 0.5 and B = 1.5. If the node B does in fact attempt to cheat by publishing an old state (such as the A=0.5 and B=1.5 state), this cheat can then be detected on-chain and used to steal the cheaters funds, i.e., A can see the closing transaction, notice it's an old one and grab all funds in the channel (A=2, B=0). The time that A has in order to react to the cheating counterparty is given by the CheckLockTimeVerify (CLTV) in the cheating transaction, which is adjustable. So if A foresees that it'll be able to check in about once every 24 hours it'll require that the CLTV is at least that large, if it's once a week then that's fine too. You definitely do not need to be online and watching the chain 24/7, just make sure to check in once in a while before the CLTV expires. Alternatively you can outsource the watch duties, in order to keep the CLTV timeouts low. This can be achieved both with trusted third parties or untrusted ones (watchtowers). In the case of a unilateral close, e.g., you just go offline and never come back, the other endpoint will have to wait for that timeout to expire to get its funds back. So peers might not accept channels with extremely high CLTV timeouts. -- Source
What Are Lightning’s Advantages?
Tiny payments are possible: since fees are proportional to the payment amount, you can pay a fraction of a cent; accounting is even done in thousandths of a satoshi. Payments are settled instantly: the money is sent in the time it takes to cross the network to your destination and back, typically a fraction of a second.
Does Lightning require Segregated Witness?
Yes, but not in theory. You could make a poorer lightning network without it, which has higher risks when establishing channels (you might have to wait a month if things go wrong!), has limited channel lifetime, longer minimum payment expiry times on each hop, is less efficient and has less robust outsourcing. The entire spec as written today assumes segregated witness, as it solves all these problems.
Can I Send Funds From Lightning to a Normal Bitcoin Address?
No, for now. For the first version of the protocol, if you wanted to send a normal bitcoin transaction using your channel, you have to close it, send the funds, then reopen the channel (3 transactions). In future versions, you and your peer would agree to spend out of your lightning channel funds just like a normal bitcoin payment, allowing you to use your lightning wallet like a normal bitcoin wallet.
Can I Make Money Running a Lightning Node?
Not really. Anyone can set up a node, and so it’s a race to the bottom on fees. In practice, we may see the network use a nominal fee and not change very much, which only provides an incremental incentive to route on a node you’re going to use yourself, and not enough to run one merely for fees. Having clients use criteria other than fees (e.g. randomness, diversity) in route selection will also help this.
What is the release date for Lightning on Mainnet?
Lightning is already being tested on the Mainnet Twitter Link but as for a specific date, Jameson Lopp says it best
Would there be any KYC/AML issues with certain nodes?
Nope, because there is no custody ever involved. It's just like forwarding packets. -- Source
What is the delay time for the recipient of a transaction receiving confirmation?
Furthermore, the Lightning Network scales not with the transaction throughput of the underlying blockchain, but with modern data processing and latency limits - payments can be made nearly as quickly as packets can be sent. -- Source

Bitcoin Stack Exchange Answer
How would the lightning network work between exchanges?
Each exchange will get to decide and need to implement the software into their system, but some ideas have been outlined here: Google Doc - Lightning Exchanges
Note that by virtue of the usual benefits of cost-less, instantaneous transactions, lightning will make arbitrage between exchanges much more efficient and thus lead to consistent pricing across exchange that adopt it. -- Source
How do lightning nodes find other lightning nodes?
Stack Exchange Answer
Does every user need to store the state of the complete Lightning Network?
According to Rusty's calculations we should be able to store 1 million nodes in about 100 MB, so that should work even for mobile phones. Beyond that we have some proposals ready to lighten the load on endpoints, but we'll cross that bridge when we get there. -- Source
Would I need to download the complete state every time I open the App and make a payment?
No you'd remember the information from the last time you started the app and only sync the differences. This is not yet implemented, but it shouldn't be too hard to get a preliminary protocol working if that turns out to be a problem. -- Source
What needs to happen for the Lightning Network to be deployed and what can I do as a user to help?
Lightning is based on participants in the network running lightning node software that enables them to interact with other nodes. This does not require being a full bitcoin node, but you will have to run "lnd", "eclair", or one of the other node softwares listed above.
All lightning wallets have node software integrated into them, because that is necessary to create payment channels and conduct payments on the network, but you can also intentionally run lnd or similar for public benefit - e.g. you can hold open payment channels or channels with higher volume, than you need for your own transactions. You would be compensated in modest fees by those who transact across your node with multi-hop payments. -- Source
Is there anyway for someone who isn't a developer to meaningfully contribute?
Sure, you can help write up educational material. You can learn and read more about the tech at http://dev.lightning.community/resources. You can test the various desktop and mobile apps out there (Lightning Desktop, Zap, Eclair apps). -- Source
Do I need to be a miner to be a Lightning Network node?
No -- Source
Do I need to run a full Bitcoin node to run a lightning node?
lit doesn't depend on having your own full node -- it automatically connects to full nodes on the network. -- Source
LND uses a light client mode, so it doesn't require a full node. The name of the light client it uses is called neutrino
How does the lightning network stop "Cheating" (Someone broadcasting an old transaction)?
Upon opening a channel, the two endpoints first agree on a reserve value, below which the channel balance may not drop. This is to make sure that both endpoints always have some skin in the game as rustyreddit puts it :-)
For a cheat to become worth it, the opponent has to be absolutely sure that you cannot retaliate against him during the timeout. So he has to make sure you never ever get network connectivity during that time. Having someone else also watching for channel closures and notifying you, or releasing a canned retaliation, makes this even harder for the attacker. This is because if he misjudged you being truly offline you can retaliate by grabbing all of its funds. Spotty connections, DDoS, and similar will not provide the attacker the necessary guarantees to make cheating worthwhile. Any form of uncertainty about your online status acts as a deterrent to the other endpoint. -- Source
How many times would someone need to open and close their lightning channels?
You typically want to have more than one channel open at any given time for redundancy's sake. And we imagine open and close will probably be automated for the most part. In fact we already have a feature in LND called autopilot that can automatically open channels for a user.
Frequency will depend whether the funds are needed on-chain or more useful on LN. -- Source
Will the lightning network reduce BTC Liquidity due to "locking-up" funds in channels?
Stack Exchange Answer
Can the Lightning Network work on any other cryptocurrency? How?
Stack Exchange Answer
When setting up a Lightning Network Node are fees set for the entire node, or each channel when opened?
You don't really set up a "node" in the sense that anyone with more than one channel can automatically be a node and route payments. Fees on LN can be set by the node, and can change dynamically on the network. -- Source
Can Lightning routing fees be changed dynamically, without closing channels?
Yes but it has to be implemented in the Lightning software being used. -- Source
How can you make sure that there will be routes with large enough balances to handle transactions?
You won't have to do anything. With autopilot enabled, it'll automatically open and close channels based on the availability of the network. -- Source
How does the Lightning Network stop flooding nodes (DDoS) with micro transactions? Is this even an issue?

The History, The Current State And The Future Of NavCoin

The History, The Current State And The Future Of NavCoin

This is it. If you're interested to see what NAV is all about, this is the ultimate guide for you. You will learn about the history of NavCoin and how it evolved. You will learn about the current state and features of NavCoin and you will learn about the exciting new features that are planned and coming up in the (near) future.
So buckle up, this is going to be a long ride!

Table Of Content


Introduction - What is NavCoin?


The History

Introduction
The following chapter will summarize and break down the history of NavCoin in a few sentences. NAV started a long time ago, went through rebrandings and changes of the core team before it became what it is today.

SummerCoin
NavCoin was initially first introduced under the name SummerCoin on April 23 in 2014. SummerCoin was a fork of the Bitcoin blockchain. It used to have a PoW/PoS hybrid algorithm with a block time of 45 seconds.

SummerCoinV2 /NavajoCoin
Soon after the initial launch of SummerCoin, the original developer left and SoopY (soopy452000 on bitcointalk) took over as the main developer and rebranded the project to SummerCoinV2 respectively NavajoCoin and introduced new features.
The name NavajoCoin was chosen in honor of the Navajo Code Talker. The unbreakable Navajo code was used to encrypt highly classified military information and commands and decrypt the same in WW II.
SoopY introduced a technology which allowed sending transactions anonymously and private. This technology was called "Navajo Anonymous Technology". SoopY also released a new wallet and set the Proof of Stake rewards at 10% for the first year, 5% for the second year and 2% for every year after.

NavCoin
On August 12, 2014, Craig (current lead core developer, pakage on bitcointalk) started to get involved with NAV by helping to set up a website [10].
It was officially announced that Craig joined the core team as a "Wallet & Web Developer" on November 06, 2014.
The last tokenswap and restart of the blockchain of NAV happened on May 12, 2016.
Soon later, SoopY stopped showing up and Craig stepped into the role of the lead core developer. Since then, Craig has assembled a strong team with which he built NavCoin into what it is today.
Currently, Craig and the NavCoin Core team is located in New Zealand and they are actively developing many ground-braking features which differentiate NAV from other cryptocurrencies. You will read more about that later in this article.

The Current State

Introduction
The year 2018 has been a thriving year for the NavCoin ecosystem. Despite the USD price of NAV not reflecting it, in 2018 the core team has developed a whole bunch of new features. Also the core content creators published the first official guidelines that function as an orientation guide for community content creators. This chapter will give you an overview of the current team, the features, the prior mentioned guidelines and the community of NavCoin.

Core Team [1]
Last year, the core team has grown alot. It contains of developers, content creators and interns. The core team are employees of Encrypt S, the New Zealand's leading blockchain R&D lab. Encrypt S is developing blockchain solutions since 2014 and values building open-source software highly.

Craig MacGregor - Chief Executive Officer
Craig is the CEO of Encrypt S and the founder of NavCoin. He is one of the world's most experienced blockchain developers. Craig founded NavCoin in 2014 and is developing software for it since then. He has assembled a strong team of like-minded people. Craig also speaks at seminars and conferenced. Some of the companies and conferences he did blockchain education sessions at are Oracle, Xero, Air New Zealand, Blok Tex and trademe. Together with the team, he is also doing a education series on YouTube where he explains upcoming features in-depth for the community.

Alex Vazquez - Chief Technical Officer
Alex is the CTO of Encrypt S and the most active contributor to the NavCoin core Github. He has incredible knowledge of blockchains and proposes and implements solutions for challenges and features. He supports community developers frequently and answers any questions of the community thoroughly. Like Craig, Alex is developing software for the NavCoin ecosystem for a very long time. Alex speaks at universities at times and educates students about the blockchain technology.

Paul Sanderson - Lead Software Engineer
Paul is the Lead Software Engineer at Encrypt S. He has a flair for technology. His technical and management skills are perfectly suited for consultancy and investment advising. He also frequently contributes to the NavCoin core source code.

Rowan Savage - Senior Software Engineer
Rowan is a full stack software engineer with more than a decade experience in developing complex front-end web applications. He joined Encrypt S in February 2018 and has since been involved in the Valence Plattform, the Kauri Wallet and NavCoin Core. You will read more about these feature/projects later.

Carter Xiao - Lead UX/UI Designer

John Darby - Content Creator John is an internationally awarded Technology and Financial sector marketing communications specialist. He is one of the Core Content Creators for NavCoin.

Features of NavCoin [2]
The following features are currently available and have been developed in the last months and years. It is sorted from newest to oldest.

Static Block Reward
The soft-fork for the enabling of static block rewards have been accepted and became active recently at 5th January 2019. This means, that the block reward was changed from a percentage based reward to a static reward. This will incentivize the stakers to have their node online 24/7 which increased the security of the network. It also aligns NavCoin with the PoSv3 specification. With this implementation, the yearly inflation will be 3.6% currently and will exponentionally decrease because of the static value of the rewards. Every staked block will now give the staker 2 NAV. Depending on how many people are staking, the yearly percentage varies. With the network weight currently being around 20'000'000 NAV, stakers earn around 10% rewards from staking 24/7.

Cold staking
To provide extra security to participants in the staking process in the NavCoin network, the core team decided to implement cold staking. This allows to store NAV offline and still be able to sign staking inputs. Looking forward, a possible integration into the Ledger Nano S would mean, that one can stake NAV securely from a offline hardware wallet. How cool is that?

OpenAlias
One of the core principle of NAV is to simplify cryptocurrencies. Many non-technical people are deterred from the long, cryptic addresses used in wallets. When sending funds, you have to make sure that every single letter and digit is correct which is nerve-wracking for the average person. NavCoin has implemented OpenAlias, which allows to transform the wallet address into a email-like form. Everyone can register a name like "[[email protected]](mailto:[email protected])". Funds can then be sent to this name, which makes sending crypto much easier and less error-prone.

Community Fund
This is the one big feature I was most excited about. NavCoin core has implemented the first fully decentralized community fund. Acceptance of proposals and release of funds is all approved by the decentralized network. No central authority has access to the fund. The community fund enables everyone to propose their ideas to the NavCoin community and to get paid to implement these ideas. Everyone can propose whatever they like (of course there is a higher rate of success if the proposal contributes to the NavCoin ecosystem ;-)). In fact, this article was sponsored by the NAV-Community by voting "yes" for my proposal. The fund works like this:
For a fee of 50 NAV, everyone can create and present his idea/proposal to the entire NavCoin network. The fee is here to help prevent spam attacks. Proposals can literally be anything - be it development, marketing or anything else you can some up with.
After creating the proposal, everyone contributing to the NavCoin network can then decide if they like the proposal of not. They vote with "Yes" or "No" for the acceptance of the proposal. Voting happens via staking. Every transaction that gets validated by you gives you one vote. This means that the more NAV you are staking, the higher your voting weight is.
The proposal stays in the state "Pending" until it is accepted or rejected. To be accepted, a proposal has to have a participation of at least 50% of all staked blocks and at least 75% of these votes have to be "Yes"-votes. Like-wise to be rejected a proposal need 50% participation of the network and 75% of these votes have to be "No"-votes. Additionally, if a proposal didn't pass after 6 voting cycles (about 6 weeks) it is also rejected.
After a proposal has been accepted, the creator of the proposal can start his work. When the work is finished, or at in the proposal defined checkpoints, the proposal creator can create a payment request for the full or part of the requested funds.
The NavCoin network can then again decide, if the work is what the creator promised to do and vote for the funds or reject the payment request because it was not what he promised. This mechanism ensures, that the funds are only release if the creator of the proposal did what he promised. The NavCoin network decides everything, there is no central authority which makes the community fund 100% decentralized.
The community fund is quite new but there have already been some proposals that were accepted like paying for the development & hosting of NAV block explorer, the creation and distribution of NAV car stickers to the community for free (or paid by the community fund), the funding of interns for NavCoin Core, translation of the website into other languages and YouTube videos. What ideas could you come up with? By the way: this article was also sponsored by the community fund :-)

Proof of Stake
Like said before, NavCoin uses the Proof of Stake algorithm to create and validate blocks. Participants of the NavCoin network can earn rewards by putting their coins to stake and thus validating blocks and securing the network. The reward used to be 4% fixed but recently changed with the implementation of PoSv3. Currently, rewards for stakers that are staking 24/7 is about 10% but it is dependent on how many people are staking. If more nodes come online, this reward will go down. If 90% of all NAVs would be at stake, stakers would still earn 4%.

Tutorials And Guidelines [3]
The NavCoin Core team pushes the community to contribute to the NavCoin ecosystem constantly. They emphasize that NavCoin is an open source project and everyone can contribute. The team tries to make it as easy as possible for the average person to contribute and thus created different tutorials and guidelines.

Tutorials To Contribute To The Website
The whole website is open source. Everyone can contribute to the website. The team created different guides for people to follow [4].

The NavCoin Developer Manifesto
The content creator core team has build a developer manifesto. It defines the values that should be uphold like for example that they will always operate in the best interest of the network. If defines the principles, purposes, scope of involvement and operational requirements [5].

The NavCoin Content Creation Manifesto
Similar to the developer manifesto, there is also a content creation manifesto. Again it defines the principles for creating content, the purpose, the scope of involvement and the operational requirements [6].

NavCoin Brand Guidelines
In addition to the content creation manifesto, there is also a brand guideline booklet. This should help content creators to create images, videos, articles etc. in the same style as the core team. It defines the NAV brand. The brand guidelines contain definitions, the language to use (words to use, words not to use), the tone of voice, what the community aspires to be and what we discourage to be. It also contains the logo pack which can be used in graphics etc. It describes correct logo spacing, logo placement, the colors of NAV and different web assets. It gives tips about gradients and overlays, the typefaces (with a font pack) and many more. Check it out yourself [7].

NavCoin Educational Series
The core team has decided to actively involve the community in the creation of new features. For this reason and to allow users to ask questions, they created the NavCoin Educational Series. The core team schedules an online live meetup which can be joined by everyone. On YouTube they do live-streams and explain upcoming features. Examples of these series are explanations for cold staking, static rewards (PoSv3) and the community fund. The community can ask questions live and the core team will answer them immediately.

Community
During the last year there have been an influx of software developers from the community starting to create features for NAV.

navexplorer.com
An examples is navexplorer.com which is programmed by community developer prodpeak and is a block explorer for NavCoin. Additionally, it functions as a interface to see what is going on in the community fund. It shows pending proposals and payment requests.

NEXT Wallet
The NEXT Wallet is an alternative wallet for NAV and other cryptocurrencies. It has a beautiful user interface and is additionally the easiest interface to interact with the community fund (create proposals, create payment requests and vote for proposals and payment requests). It is programmed by community developer sakdeniz who put hundreds of hours into it during last year.

There were also some marketing activities starting to emerge with the release of the community fund. Some of these were for example free stickers for everyone in the NAV community to stick to their car / shop / window etc. or YouTube videos of CryptoCandor and Cryptomoonie that explained the details of NAV. I am sure, that with the 500'000 NAV available in the community fund per year there will be an influx of gread ideas - development as well as marketing activities - that will be funded.

The Future

Introduction
These features are planned for the future. Many of the following features are part of the 2019 roadmap. Some will not be described in great detail because not much is known about them yet. I've still listed them as they are part of what is yet to come.

Features
Rimu - Improved Privacy Solution
NavCoin used to be a optional privacy coin. That means, that you could choose to send a transaction in private. NavCoin was criticized for the way it handles private payments because it relied on a few servers which didn't make it that decentralized. The technology was called "NavTech" and was a secondary blockchain that obscured the transaction and the amount that was sent. NavCoin Core is currently developing a new improved privacy solution that will make the private payment system completely trustless and districuted and runs at a protocol level. Alex of the NavCoin Core team has published a paper that describes this new privacy solution. It's called Zero Confidential Transactions and can be found here: https://www.researchgate.net/publication/330366788_ZeroCT_Improving_Zerocoin_with_Confidential_Transactions_and_more. What I want to highlight is the collaboration between Alex as the proposer of the solution and the Veil team, a Bitcoin Core developer and Moneros main cryptographer as reviewers. When the best work together, it will be interesting to see what the outcome is!

Valence Plattform [8]
Valence is an applied Blockchain platform that can help businesses realise the tangible benefits of blockchain. You can think of Valence as a platform with which you can build Anonymous Distributed Applications (aDapps) with. But Valence is a different kind of platform that enables developers to create new types of blockchain applications. The problem with current (turing complete) dApp platforms are their complexity and rigid nature. Security holes in smart contracts and scaling issues happen frequently [9].
Valence provides transitional pathways that let businesses migrate only part of their activities to the blockchain without having to restructure their entire business model [9].
Valence will provide a spectrum of blockchain application solutions which sit along the decentralized spectrum, offering businesses simple ways to dip their toes into the blockchain at minimal risk or complexity [9].
Thanks to the proof of stake nature of the Valence blockchain, more of a node's resources can be used for processing and routing application data which makes the platform faster and scalable.
Valence aims to make building blockchain applications as accessible to the general public as WordPress or Squarespace has made building websites.
The developers NavCoin and Valence aim to make Valence extremely easy to work with:
A Valence application could be an open source mobile or web application that submits unencrypted or encrypted data directly to the blockchain. The only configuration necessary for the app developer would be setting up the data structure. Once they've done that they can start writing to the blockchain immediately.
The Valence blockchain interface is language agnostic, meaning developers are free to build applications in whichever language they're familiar with, which greatly reduces the barrier to entry.
As the platform progresses, Valence will introduce more and more smart contract templates in collaboration with the development community. These will be like plugins that users can simply select and configure for their application, without having to reinvent the wheel and risk contract errors or spend countless hours of research to program them.

NavShopper
The following information is taken from the latest weekly news: NavShopper is a new project which will allow people to spend NavCoin on a growing list of retailers and service providers. NavShopper sits between traditional retailers accepting fiat and NavCoin users and purchases products on behalf of the user by managing the crypt-fiat conversion, payment and shipping. This project will unlock many more ways for people to spend NAV on existing websites/marketplaces without requiring each site to individually accept cryptocurrencies. Some of the prototypes we are working on include crediting your Uber account, buying products on Amazon and donating to charities.

Kauri Wallet
The Kauri Wallet aims to be an open-source, multi-currency wallet which functions as a foundation for other features.

Kauri Enhanced
Enhancements to the Kauri Wallet will allow multiple accounts, pin numbers, recurring payments and more.

Kauri DAEx
The Kauri DAEx is a Decentralised Atomic Exchange that utilises the features of the Kauri Wallet and enables users to create safe peer to peer atomic exchanges for any currency supported by the Kauri Wallet. NavDelta NavDelta will be a payment gateway that allows users to spend NAV at any business which accepts currencies supported by the Kauri Wallet. NavMorph NavMorph is a fusion of Rimu and Kauri DAEx and will allow to privately send every cryptocurrency supported by the Kauri Wallet.

Outro

If you have made it this far: Congratulations! You have learned about how NAV evolved, what its current state is and what the future will bring. To sum all up: NavCoin has made incredible progress during last year and released many long awaited features despite the bear market. Many more exciting features are yet to come and it's going to be very interesting to see where we will stand on this day next year.

Giveaway

Unfortunately, the giveaway was not possible in the cryptocurrency-subreddit because of their rules, so I'm doing it here :-) As a surprise, in the next 2 hours I am going to send some NAV to everyone who wants to try out the awesome features and NavPay you read about above.
To get your NAVs, all you have to do is the following:
If you liked the experience, I'd be happy to hear back from you :)

Lisk Highlights roundup May 27th 2019: Lisk Blockchain gains a fresh library for Apple's Swift 5 programming language.

Hello there. Here is my selection for today's highlights and interesting items within the Lisk ecosystem and beyond.....

Lisk Blockchain gains a fresh library for Apple's Swift 5 programming language.

sayler8182 on Github AKA Konrad Piękoś has created a Swift 5 library for Lisk that he has named RxLisk. It allows developers to interact with the core Lisk API, for retrieval of collections and single records of data located on the Lisk blockchain. It doesn't require a locally installed Lisk node, and instead utilizes the existing peers on the network (mainnet or testnet). It can be used on any environment that runs Swift 4. RxLisk is heavily inspired by Lisk Swift, an earlier Swift 4 library for Lisk. You can download RxLisk from Github here. Don't forget to give the repository a star if you believe it to be of value.
Swift 5's code is represented in machine code, and it has a compiler that uses an Application Binary Interface (ABI). Before the release of Swift 5, when you generated a binary, some files were also included with the binary, called the Swift standard library and runtime. These represent the Swift ABI. From Swift 5 going forward, this ABI will be standardized and all future versions of Swift will be compatible with this ABI. This means that operating systems that run Swift binaries (such as iOS, tvOS, macOS, watchOS) will be able to embed the Swift ABI, meaning that apps will no longer need to embed them. This will result in smaller app bundles. Due to this embedding factor compatibility it means that applications and libraries that may have been compiled with different Swift versions should not be a problem going forward. For this reason it is good news to see that the Lisk project is being kept parallel with the latest changes in Swift via community contributions such as this RxLisk library from sayler8182.
If you are interested in learning even more about Swift, well this youtube video titled "iOS Swift Tutorial: Awesome New Swift 5 Features" should fill you in further on the latest Swift changes.
 
That's it for today's highlights.

The History, The Current State And The Future Of NavCoin

The History, The Current State And The Future Of NavCoin

This is it. If you're interested to see what NAV is all about, this is the ultimate guide for you. You will learn about the history of NavCoin and how it evolved. You will learn about the current state and features of NavCoin and you will learn about the exciting new features that are planned and coming up in the (near) future.
So buckle up, this is going to be a long ride!

Introduction - What is NavCoin?


The History

Introduction
The following chapter will summarize and break down the history of NavCoin in a few sentences. NAV started a long time ago, went through rebrandings and changes of the core team before it became what it is today.

SummerCoin
NavCoin was initially first introduced under the name SummerCoin on April 23 in 2014. SummerCoin was a fork of the Bitcoin blockchain. It used to have a PoW/PoS hybrid algorithm with a block time of 45 seconds.

SummerCoinV2 /NavajoCoin
Soon after the initial launch of SummerCoin, the original developer left and SoopY (soopy452000 on bitcointalk) took over as the main developer and rebranded the project to SummerCoinV2 respectively NavajoCoin and introduced new features.
The name NavajoCoin was chosen in honor of the Navajo Code Talker. The unbreakable Navajo code was used to encrypt highly classified military information and commands and decrypt the same in WW II.
SoopY introduced a technology which allowed sending transactions anonymously and private. This technology was called "Navajo Anonymous Technology". SoopY also released a new wallet and set the Proof of Stake rewards at 10% for the first year, 5% for the second year and 2% for every year after.

NavCoin
On August 12, 2014, Craig (current lead core developer, pakage on bitcointalk) started to get involved with NAV by helping to set up a website [10].
It was officially announced that Craig joined the core team as a "Wallet & Web Developer" on November 06, 2014.
The last tokenswap and restart of the blockchain of NAV happened on May 12, 2016.
Soon later, SoopY stopped showing up and Craig stepped into the role of the lead core developer. Since then, Craig has assembled a strong team with which he built NavCoin into what it is today.
Currently, Craig and the NavCoin Core team is located in New Zealand and they are actively developing many ground-braking features which differentiate NAV from other cryptocurrencies. You will read more about that later in this article.

The Current State

Introduction
The year 2018 has been a thriving year for the NavCoin ecosystem. Despite the USD price of NAV not reflecting it, in 2018 the core team has developed a whole bunch of new features. Also the core content creators published the first official guidelines that function as an orientation guide for community content creators. This chapter will give you an overview of the current team, the features, the prior mentioned guidelines and the community of NavCoin.

Core Team [1]
Last year, the core team has grown alot. It contains of developers, content creators and interns. The core team are employees of Encrypt S, the New Zealand's leading blockchain R&D lab. Encrypt S is developing blockchain solutions since 2014 and values building open-source software highly.

Craig MacGregor - Chief Executive Officer
Craig is the CEO of Encrypt S and the founder of NavCoin. He is one of the world's most experienced blockchain developers. Craig founded NavCoin in 2014 and is developing software for it since then. He has assembled a strong team of like-minded people. Craig also speaks at seminars and conferenced. Some of the companies and conferences he did blockchain education sessions at are Oracle, Xero, Air New Zealand, Blok Tex and trademe. Together with the team, he is also doing a education series on YouTube where he explains upcoming features in-depth for the community.

Alex Vazquez - Chief Technical Officer
Alex is the CTO of Encrypt S and the most active contributor to the NavCoin core Github. He has incredible knowledge of blockchains and proposes and implements solutions for challenges and features. He supports community developers frequently and answers any questions of the community thoroughly. Like Craig, Alex is developing software for the NavCoin ecosystem for a very long time. Alex speaks at universities at times and educates students about the blockchain technology.

Paul Sanderson - Lead Software Engineer
Paul is the Lead Software Engineer at Encrypt S. He has a flair for technology. His technical and management skills are perfectly suited for consultancy and investment advising. He also frequently contributes to the NavCoin core source code.

Rowan Savage - Senior Software Engineer
Rowan is a full stack software engineer with more than a decade experience in developing complex front-end web applications. He joined Encrypt S in February 2018 and has since been involved in the Valence Plattform, the Kauri Wallet and NavCoin Core. You will read more about these feature/projects later.

Carter Xiao - Lead UX/UI Designer
Carter specializes in user-centric design and is also very talented with 3D animation, motion graphics and programming. One of NavCoins core principle is "Simplifying Crypto" and UX/UI is a very important part of that.

Valence provides transitional pathways that let businesses migrate only part of their activities to the blockchain without having to restructure their entire business model [9].
Valence will provide a spectrum of blockchain application solutions which sit along the decentralized spectrum, offering businesses simple ways to dip their toes into the blockchain at minimal risk or complexity [9].
Thanks to the proof of stake nature of the Valence blockchain, more of a node's resources can be used for processing and routing application data which makes the platform faster and scalable.
Valence aims to make building blockchain applications as accessible to the general public as WordPress or Squarespace has made building websites.
The developers NavCoin and Valence aim to make Valence extremely easy to work with:
A Valence application could be an open source mobile or web application that submits unencrypted or encrypted data directly to the blockchain. The only configuration necessary for the app developer would be setting up the data structure. Once they've done that they can start writing to the blockchain immediately.
The Valence blockchain interface is language agnostic, meaning developers are free to build applications in whichever language they're familiar with, which greatly reduces the barrier to entry.
As the platform progresses, Valence will introduce more and more smart contract templates in collaboration with the development community. These will be like plugins that users can simply select and configure for their application, without having to reinvent the wheel and risk contract errors or spend countless hours of research to program them.

NavShopper
The following information is taken from the latest weekly news: NavShopper is a new project which will allow people to spend NavCoin on a growing list of retailers and service providers. NavShopper sits between traditional retailers accepting fiat and NavCoin users and purchases products on behalf of the user by managing the crypt-fiat conversion, payment and shipping. This project will unlock many more ways for people to spend NAV on existing websites/marketplaces without requiring each site to individually accept cryptocurrencies. Some of the prototypes we are working on include crediting your Uber account, buying products on Amazon and donating to charities.

Kauri Wallet
The Kauri Wallet aims to be an open-source, multi-currency wallet which functions as a foundation for other features.

Kauri Enhanced
Enhancements to the Kauri Wallet will allow multiple accounts, pin numbers, recurring payments and more.

Kauri DAEx
The Kauri DAEx is a Decentralised Atomic Exchange that utilises the features of the Kauri Wallet and enables users to create safe peer to peer atomic exchanges for any currency supported by the Kauri Wallet. NavDelta NavDelta will be a payment gateway that allows users to spend NAV at any business which accepts currencies supported by the Kauri Wallet. NavMorph NavMorph is a fusion of Rimu and Kauri DAEx and will allow to privately send every cryptocurrency supported by the Kauri Wallet.

Outro

If you have made it this far: Congratulations! You have learned about how NAV evolved, what its current state is and what the future will bring. To sum all up: NavCoin has made incredible progress during last year and released many long awaited features despite the bear market. Many more exciting features are yet to come and it's going to be very interesting to see where we will stand on this day next year.

Giveaway

Unfortunately, the giveaway was not possible in the cryptocurrency-subreddit because of their rules, so I'm doing it here :-) As a surprise, in the next few hours I am going to send some NAV to everyone who wants to try out the awesome features you have read about above.
To get your NAVs, all you have to do is the following:
If you liked the experience, I'd be happy to hear back from you :)

[META] New to PC Building? - September 2018 Edition

Intro

You've heard from all your gaming friends/family or co-workers that custom PCs are the way to go. Or maybe you've been fed up with your HP, Dell, Acer, Gateway, Lenovo, etc. pre-builts or Macs and want some more quality and value in your next PC purchase. Or maybe you haven't built a PC in a long time and want to get back into the game. Well, here's a good place to start.

Instructions

  1. Make a budget for your PC (e.g., $800, $1000, $1250, $1500, etc.).
  2. Decide what you will use your PC for.
    • For gaming, decide what games and at what resolution and FPS you want to play at.
    • For productivity, decide what software you'll need and find the recommended specs to use those apps.
    • For a bit of both, your PC build should be built on the HIGHEST specs recommended for your applications (e.g., if you only play FortNite and need CPU power for CFD simulations, use specs recommended for CFD).
    Here are some rough estimates for builds with entirely NEW parts:
    1080p 60FPS ultra-settings modern AAA gaming: ~$1,200
    1440p 60FPS high/ultra-settings modern AAA gaming: ~$1,600
    1080p 144FPS ultra-settings modern AAA gaming: $2,000
    4K 50FPS medium/high-settings modern AAA gaming: > $2,400
    It's noted that some compromises (e.g., lower settings and/or resolution) can be made to achieve the same or slightly lower gaming experience within ±15% of the above prices. It's also noted that you can still get higher FPS on older or used PCs by lowering settings and/or resolution AND/OR buying new/used parts to upgrade your system. Make a new topic about it if you're interested.
    Also note that AAA gaming is different from e-sport games like CSGO, DOTA2, FortNite, HOTS, LoL, Overwatch, R6S, etc. Those games have lower requirements and can make do with smaller budgets.
  3. Revise your budget AND/OR resolution and FPS until both are compatible. Compare this to the recommended requirements of the most demanding game on your list. For older games, you might be able to lower your budget. For others, you might have to increase your budget.
    It helps to watch gaming benchmarks on Youtube. A good example of what you're looking for is something like this (https://www.youtube.com/watch?v=9eLxSOoSdjY). Take note of the resolution, settings, FPS, and the specs in the video title/description; ask yourself if the better gaming experience is worth increasing your budget OR if you're okay with lower settings and lowering your budget. Note that you won't be able to see FPS higher than 60FPS for Youtube videos; something like this would have to be seen in-person at a computer shop.
  4. Make a build on https://ca.pcpartpicker.com/. If you still have no idea how to put together parts, start here (http://www.logicalincrements.com/) to get an understanding of PC part tiers. If you want more info about part explanations and brief buying tips, see the next section below.
  5. Click on the Reddit logo button next to Markup, copy and paste the generated text (in markup mode if using new Reddit), and share your build for review!
  6. Consider which retailer to buy your parts from. Here's a table comparing different retailers: https://docs.google.com/spreadsheets/d/1L8uijxuoJH4mjKCjwkJbCrKprCiU8CtM15mvOXxzV1s/edit?usp=sharing
  7. Buy your parts! Use PCPP above to send you e-mail alerts on price drops or subscribe to /bapcsalescanada for deals.
    You can get parts from the following PC retailers in alphabetical order:
  8. After procuring your parts, it's time to build. Use a good Youtube tutorial like this (https://www.youtube.com/watch?v=IhX0fOUYd8Q) that teach BAPC fundamentals, but always refer to your product manuals or other Youtube tutorials for part-specific instructions like CPU mounting, radiator mounting, CMOS resetting, etc. If it everything still seems overwhelming, you can always pay a computer shop or a friend/family member to build it for you.
    It might also be smart to look up some first-time building mistakes to avoid:
  9. Share your experience with us.
  10. If you have any other questions, use the search bar first. If it's not there, make a topic.

BAPC News (Last Updated - 2018/09/20)

CPU

https://www.tomshardware.com/news/intel-9000-series-cpu-faq,37743.html
Intel 9000 CPUs (Coffee Lake Refresh) will be coming out in Q4. With the exception of i9 (8-core, 12 threads) flagship CPUs, the i3, i5, and i7 lineups are almost identical to their Intel 8000 (Coffee Lake) series, but slightly clocked faster. If you are wondering if you should upgrade to the newer CPU on the same tier (e.g., i5-8400 to i5-9400), I don't recommend that you do as you will only see marginal performance increases.

Mobo

https://www.anandtech.com/show/13135/more-details-on-intels-z390-chipset-exposed
Z370s will now be phased out for Z390s boards, which will natively support Intel 9000 CPUs (preferably i5-9600K, i7-9700K, and i9-9900K).

GPU

https://www.youtube.com/watch?v=WDrpsv0QIR0
RTX 2080 and 2080 Ti benchmarks are out; they provide ~10 and ~20 frames better than the 1080 Ti and also feature ray tracing (superior lighting and shadow effects) which is featured in only ~30 games so far (i.e., not supported a lot); effectively, they provide +25% more performance for +70% increased cost. My recommendation is NOT to buy them unless you need it for work or have lots of disposable income. GTX 1000 Pascal series are still relevant in today's gaming specs.

Part Explanations

CPU

The calculator part. More GHz is analogous to fast fingers number crunching in the calculator. More cores is analogous to having more calculators. More threads is analogous to having more filing clerks piling more work for the calculator to do. Microarchitectures (core design) is analogous to how the internal circuit inside the calculator is designed (e.g., AMD FX series are slower than Intel equivalents even with higher OC'd GHz speeds because the core design is subpar). All three are important in determining CPU speed.
In general, higher GHz is more important for gaming now whereas # cores and threads are more important for multitasking like streaming, video editing, and advanced scientific/engineering computations. Core designs from both AMD and Intel in their most recent products are very good now, but something to keep in mind.

Overclocking

The basic concept of overclocking (OCing) is to feed your CPU more power through voltage and hoping it does calculations faster. Whether your parts are good overclockers depends on the manufacturing process of your specific part and slight variations in materials and manufacturing process will result in different overclocking capability ("silicon lottery"). The downside to this is that you can void your warranties because doing this will produce excess heat that will decrease the lifespan of your parts AND that there is a trial-and-error process to finding OC settings that are stable. Unstable OC settings result in computer freezes or random shut-offs from excess heat. OCing will give you extra performance often for free or by investing in a CPU cooler to control your temperatures so that the excess heat will not decrease your parts' lifespans as much. If you don't know how to OC, don't do it.

Current Products

Intel CPUs have higher GHz than AMD CPUs, which make them better for gaming purposes. However, AMD Ryzen CPUs have more cores and threads than their Intel equivalents. The new parts are AMD Ryzen 3, 5, or 7 2000 series or Intel i3, i5, or i7 8000 series (Coffee Lake). Everything else is outdated.
If you want to overclock on an AMD system, know that you can get some moderate OC on a B350/B450 with all CPUs. X370/X470 mobos usually come with better VRMs meant for OCing 2600X, 2700, and 2700X. If you don't know how to OC, know that the -X AMD CPUs have the ability to OC themselves automatically without manually settings. For Intel systems, you cannot OC unless the CPU is an unlocked -K chip (e.g., i3-8350K, i5-8600K, i7-8700K, etc.) AND the motherboard is a Z370 mobo. In general, it is not worth getting a Z370 mobo UNLESS you are getting an i5-8600K and i7-8700K.

CPU and Mobo Compatibility

Note about Ryzen 2000 CPUs on B350 mobos: yes, you CAN pair them up since they use the same socket. You might get an error message on PCPP that says that they might not be compatible. Call the retailer and ask if the mobo you're planning on buying has a "Ryzen 2000 Series Ready" sticker on the box. This SHOULD NOT be a problem with any mobos manufactured after February 2018.
Note about Intel 9000 CPUs on B360 / Z370 mobos: same as above with Ryzen 2000 CPUs on B350 or X370 boards.

CPU Cooler (Air / Liquid)

Air or liquid cooling for your CPU. This is mostly optional unless heavy OCing on AMD Ryzen CPUs and/or on Intel -K and i7-8700 CPUs.
For more information about air and liquid cooling comparisons, see here:

Motherboard/mobo

Part that lets all the parts talk to each other. Comes in different sizes from small to big: mITX, mATX, ATX, and eATX. For most people, mATX is cost-effective and does the job perfectly. If you need more features like extra USB slots, go for an ATX. mITX is for those who want a really small form factor and are willing to pay a premium for it. eATX mobos are like ATX mobos except that they have more features and are bigger - meant for super PC enthusiasts who need the features.
If you are NOT OCing, pick whatever is cheap and meets your specs. I recommend ASUS or MSI because they have RMA centres in Canada in case it breaks whereas other parts are outside of Canada like in the US. If you are OCing, then you need to look at the quality of the VRMs because those will greatly influence the stability and lifespan of your parts.

Memory/RAM

Part that keeps Windows and your software active. Currently runs on the DDR4 platform for new builds. Go for dual channel whenever possible. Here's a breakdown of how much RAM you need:
AMD Ryzen CPUs get extra FPS for faster RAM speeds (ideally 3200MHz) in gaming when paired with powerful video cards like the GTX 1070. Intel Coffee Lake CPUs use up a max of 2667MHz for B360 mobos. Higher end Z370 mobos can support 4000 - 4333MHz RAM depending on the mobo, so make sure you shop carefully!
It's noted that RAM prices are highly inflated because of the smartphone industry and possibly artificial supply shortages. For more information: https://www.extremetech.com/computing/263031-ram-prices-roof-stuck-way

Storage

Part that store your files in the form of SSDs and HDDs.

Solid State Drives (SSDs)

SSDs are incredibly quick, but are expensive per TB; they are good for booting up Windows and for reducing loading times for gaming. For an old OEM pre-built, upgrading the PC with an SSD is the single greatest speed booster you can do to your system. For most people, you want to make sure the SSD you get is NOT DRAM-less as these SSDs do not last as long as their DRAM counterparts (https://www.youtube.com/watch?v=ybIXsrLCgdM). It is also noted that the bigger the capacity of the SSD, the faster they are. SSDs come in four forms:
The 2.5" SATA form is cheaper, but it is the old format with speeds up to 550MB/s. M.2 SATA SSDs have the same transfer speeds as 2.5" SATA SSDs since they use the SATA interface, but connect directly to the mobo without a cable. It's better for cable management to get an M.2 SATA SSD over a 2.5" SATA III SSD. M.2 PCI-e SSDs are the newest SSD format and transfer up to 4GB/s depending on the PCI-e lanes they use (e.g., 1x, 2x, 4x, etc.). They're great for moving large files (e.g., 4K video production). For more info about U.2 drives, see this post (https://www.reddit.com/bapccanada/comments/8jxfqs/meta_new_to_pc_building_may_2018_edition/dzqj5ks/). Currently more common for enterprise builds, but could see some usage in consumer builds.

Hard Disk Drives (HDDs)

HDDs are slow with transfer speeds of ~100MB/s, but are cheap per TB compared to SSDs. We are now at SATA III speeds, which have a max theoretical transfer rate of 600MB/s. They also come in 5400RPM and 7200RPM forms. 5400RPM uses slightly less power and are cheaper, but aren't as fast at dealing with a large number of small files as 7200RPM HDDs. When dealing with a small number of large files, they have roughly equivalent performance. It is noted that even a 10,000RPM HDD will still be slower than an average 2.5" SATA III SSD.

Others

SSHDs are hybrids of SSDs and HDDs. Although they seem like a good combination, it's much better in all cases to get a dedicated SSD and a dedicated HDD instead. This is because the $/speed better for SSDs and the $/TB is better for HDDs. The same can be said for Intel Optane. They both have their uses, but for most users, aren't worth it.

Overall

I recommend a 2.5" or M.2 SATA ≥ 250GB DRAM SSD and a 1TB or 2TB 7200RPM HDD configuration for most users for a balance of speed and storage capacity.

Video Card/GPU

Part that runs complex calculations in games and outputs to your monitor and is usually the most expensive part of the budget. The GPU you pick is dictated by the gaming resolution and FPS you want to play at.
In general, all video cards of the same product name have almost the same non-OC'd performance (e.g., Asus Dual-GTX1060-06G has the same performance as the EVGA 06G-P4-6163-KR SC GAMING). The different sizes and # fans DO affect GPU OCing capability, however. The most important thing here is to get an open-air video card, NOT a blower video card (https://www.youtube.com/watch?v=0domMRFG1Rw). The blower card is meant for upgrading pre-builts where case airflow is limited.
For cost-performance, go for the NVIDIA GTX cards because of the cryptomining industry that has inflated AMD RX cards. Bitcoin has taken a -20% hit since January's $10,000+ as of recently, but the cryptomining industry is still ongoing. Luckily, this means prices have nearly corrected itself to original MSRP in 2016.
In general:
Note that if your monitor has FreeSync technology, get an AMD card. If your monitor has G-Sync, get a NVIDIA card. Both technologies allow for smooth FPS gameplay. If you don't have either, it doesn't really matter which brand you get.
For AMD RX cards, visit https://www.pcworld.com/article/3197885/components-graphics/every-amd-radeon-rx-graphics-card-you-can-buy-for-pc-gaming.html

New NVIDIA GeForce RTX Series

New NVIDIA 2000 RTX series have been recently announced and will be carried in stores in Q3 and Q4. Until all of the products have been fully vetted and reviewed, we cannot recommend those yet as I cannot say if they are worth what NVIDIA has marketed them as. But they will be faster than their previous equivalents and will require more wattage to use. The 2070, 2080, and 2080 Ti will feature ray tracing, which is a new feature seen in modern CG movies that greatly enhances lighting and shadow effects. At this time, < 30 games will use ray tracing (https://www.pcgamer.com/21-games-will-support-nvidias-real-time-ray-tracing-here-are-demos-of-tomb-raider-and-control/). It's also noted that the 2080 Ti is the Titan XP equivalent, which is why it's so expensive. (https://www.youtube.com/watch?v=Irs8jyEmmPQ) The community's general recommendation is NOT to pre-order them until we see some reviews and benchmarks from reviewers first.
Looks like a couple of benchmarks are out. While keeping other parts equal the following results were obtained(https://videocardz.com/77983/nvidia-geforce-rtx-2080-ti-and-rtx-2080-official-performance-unveiled). So the 2080 and 2080 Ti are better than last generation's 1080 Ti by ~10 and ~20 frames respectively.

Case

Part that houses your parts and protects them from its environment. Should often be the last part you choose because the selection is big enough to be compatible with any build you choose as long as the case is equal to or bigger than the mobo form factor.
Things to consider: aesthetics, case airflow, cable management, material, cooling options (radiators or # of fan spaces), # fans included, # drive bays, toolless installation, power supply shroud, GPU clearance length, window if applicable (e.g., acrylic, tempered glass), etc.
It is recommended to watch or read case reviews on Youtube to get an idea of a case's performance in your setup.

Power Supply/PSU

Part that runs your PC from the wall socket. Never go with an non-reputable/cheap brand out on these parts as low-quality parts could damage your other parts. Recommended branded PSUs are Corsair, EVGA, Seasonic, and Thermaltake, generally. For a tier list, see here (https://linustechtips.com/main/topic/631048-psu-tier-list-updated/).

Wattage

Wattage depends on the video card chosen, if you plan to OC, and/or if you plan to upgrade to a more powerful PSU in the future. Here's a rule of thumb for non-OC wattages that meet NVIDIA's recommendations:
There are also PSU wattage calculators that you can use to estimate your wattage. How much wattage you used is based on your PC parts, how much OCing you're doing, your peripherals (e.g., gaming mouse and keyboard), and how long you plan to leave your computer running, etc. It is noted that these calculators use conservative estimates, so use the outputted wattage as a baseline of how much you need. Here are the calculators (thanks, VitaminDeity).
Pick ONE calculator to use and use the recommended wattage, NOT recommended product, as a baseline of what wattage you need for your build. Note that Cooler Master and Seasonic use the exact calculator as Outervision. For more details about wattage, here are some reference videos:

Modularity

You might also see some info about modularity (non-modular, semi-modular, or fully-modular). These describe if the cables will come connected to the PSU or can be separated of your own choosing. Non-modular PSUs have ALL of the cable connections attached to the PSU with no option to remove unneeded cables. Semi-modular PSUs have separate cables for HDDs/SSDs and PCI-e connectors, but will have CPU and mobo cables attached. Modular PSUs have all of their cables separate from each other, allowing you to fully control over cable management. It is noted that with decent cooling and airflow in your case, cable management has little effect on your temperatures (https://www.youtube.com/watch?v=YDCMMf-_ASE).

80+ Efficiency Ratings

As for ratings (80+, 80+ bronze, 80+ gold, 80+ platinum), these are the efficiencies of your PSU. Please see here for more information. If you look purely on electricity costs, the 80+ gold PSUs will be more expensive than 80+ bronze PSUs for the average Canadian user until a breakeven point of 6 years (assuming 8 hours/day usage), but often the better performance, longer warranty periods, durable build quality, and extra features like fanless cooling is worth the extra premium. In general, the rule of thumb is 80+ bronze for entry-level office PCs and 80+ gold for mid-tier or higher gaming/workstation builds. If the price difference between a 80+ bronze PSU and 80+ gold PSU is < 20%, get the 80+ gold PSU!

Warranties

Warranties should also be looked at when shopping for PSUs. In general, longer warranties also have better PSU build quality. In general, for 80+ bronze and gold PSU units from reputable brands:
Any discrepancies are based on varied wattages (i.e., higher wattages have longer warranties) or updated warranty periods. Please refer to the specific product's warranty page for the correct information. For EVGA PSUs, see here (https://www.evga.com/support/warranty/power-supplies/). For Seasonic PSUs, see here (https://seasonic.com/support#period). For Corsair PSUs, see here (https://www.corsair.com/ca/en/warranty).
For all other PSU inquiries, look up the following review sites for the PSUs you're interested in buying:
These guys are engineering experts who take apart PSUs, analyze the quality of each product, and provide an evaluation of the product. Another great website is http://www.orionpsudb.com/, which shows which PSUs are manufactured by different OEMs.

Operating System (OS)

Windows 10

The most common OS. You can download the ISO here (https://www.microsoft.com/en-ca/software-download/windows10). For instructions on how to install the ISO from a USB drive, see here (https://docs.microsoft.com/en-us/windows-hardware/manufacture/desktop/install-windows-from-a-usb-flash-drive) or watch a video here (https://www.youtube.com/watch?v=gLfnuE1unS8). For most users, go with the 64-bit version.
If you purchase a Windows 10 retail key (i.e., you buy it from a retailer or from Microsoft directly), keep in mind that you are able to transfer it between builds. So if you're building another PC for the 2nd, 3rd, etc. time, you can reuse the key for those builds PROVIDED that you deactivate your key before installing it on your new PC. These keys are ~$120.
However, if you have an OEM key (e.g., pre-builts), that key is tied specifically to your mobo. If you ever decide to upgrade your mobo on that pre-built PC, you might have to buy a new Windows 10 license. For more information, see this post (https://www.techadvisor.co.uk/feature/windows/windows-10-oem-or-retail-3665849/). The cheaper Windows 10 keys you can find on Kinguin are OEM keys; activating and deactivating these keys may require phoning an automated Microsoft activation line. Most of these keys are legitimate and cost ~$35, although Microsoft does not intend for home users to obtain this version of it. Buyer beware.
The last type of key is a volume licensing key. They are licensed in large volumes to corporate or commercial usage. You can find lots of these keys on eBay for ~$10, but if the IT department who manages these keys audit who is using these keys or if the number of activations have exceeded the number allotted on that one key, Microsoft could block that key and invalidate your license. Buyer beware.
For more information on differentiating between all three types of keys, see this page (https://www.tenforums.com/tutorials/49586-determine-if-windows-license-type-oem-retail-volume.html).
If money is tight, you can get Windows 10 from Microsoft and use a trial version of it indefinitely. However, there will be a watermark in the bottom-right of your screen until you activate your Windows key.

MacOS

If you're interested in using MacOS, look into Hackintosh builds. This will allow you to run MacOS to run on PC parts, saving you lots of money. These builds are pretty picky about part compatibility, so you might run into some headaches trying to go through with this. For more information, see the following links:

Linux

If you're interested in a free open-source OS, see the following links:
For more information, go to /linux, /linuxquestions, and /linux4noobs.

Peripherals

Monitors

Keyboards and Mice

Overall

Please note that the cost-performance builds will change daily because PC part prices change often! Some builds will have excellent cost-performance one day and then have terrible cost-performance the next. If you want to optimize cost-performance, it is your responsibility to do this if you go down this route!
Also, DO NOT PM me with PC build requests! It is in your best interests to make your own topic so you can get multiple suggestions and input from the community rather than just my own. Thanks again.

Sample Builds

Here are some sample builds that are reliable, but may not be cost-optimized builds. These builds were created on September 9, 2018; feel free to "edit this part list" and create your own builds.

Sorry for the lack of updates. I recently got a new job where I work 12 hours/day for 7 days at a time out of the city. What little spare time I have is spent on grad school and the gym instead of gaming. So I've been pretty behind on the news and some might not be up-to-date as my standards would have been with less commitments. If I've made any mistakes, please understand it might take a while for me to correct them. Thank you!
