Bitcoin (BTC)A Peer-to-Peer Electronic Cash System.

Bitcoin (BTC)A Peer-to-Peer Electronic Cash System.
  • Bitcoin (BTC) is a peer-to-peer cryptocurrency that aims to function as a means of exchange that is independent of any central authority. BTC can be transferred electronically in a secure, verifiable, and immutable way.
  • Launched in 2009, BTC is the first virtual currency to solve the double-spending issue by timestamping transactions before broadcasting them to all of the nodes in the Bitcoin network. The Bitcoin Protocol offered a solution to the Byzantine Generals’ Problem with a blockchain network structure, a notion first created by Stuart Haber and W. Scott Stornetta in 1991.
  • Bitcoin’s whitepaper was published pseudonymously in 2008 by an individual, or a group, with the pseudonym “Satoshi Nakamoto”, whose underlying identity has still not been verified.
  • The Bitcoin protocol uses an SHA-256d-based Proof-of-Work (PoW) algorithm to reach network consensus. Its network has a target block time of 10 minutes and a maximum supply of 21 million tokens, with a decaying token emission rate. To prevent fluctuation of the block time, the network’s block difficulty is re-adjusted through an algorithm based on the past 2016 block times.
  • With a block size limit capped at 1 megabyte, the Bitcoin Protocol has supported both the Lightning Network, a second-layer infrastructure for payment channels, and Segregated Witness, a soft-fork to increase the number of transactions on a block, as solutions to network scalability.

1. What is Bitcoin (BTC)?

  • Bitcoin is a peer-to-peer cryptocurrency that aims to function as a means of exchange and is independent of any central authority. Bitcoins are transferred electronically in a secure, verifiable, and immutable way.
  • Network validators, whom are often referred to as miners, participate in the SHA-256d-based Proof-of-Work consensus mechanism to determine the next global state of the blockchain.
  • The Bitcoin protocol has a target block time of 10 minutes, and a maximum supply of 21 million tokens. The only way new bitcoins can be produced is when a block producer generates a new valid block.
  • The protocol has a token emission rate that halves every 210,000 blocks, or approximately every 4 years.
  • Unlike public blockchain infrastructures supporting the development of decentralized applications (Ethereum), the Bitcoin protocol is primarily used only for payments, and has only very limited support for smart contract-like functionalities (Bitcoin “Script” is mostly used to create certain conditions before bitcoins are used to be spent).

2. Bitcoin’s core features

For a more beginner’s introduction to Bitcoin, please visit Binance Academy’s guide to Bitcoin.

Unspent Transaction Output (UTXO) model

A UTXO transaction works like cash payment between two parties: Alice gives money to Bob and receives change (i.e., unspent amount). In comparison, blockchains like Ethereum rely on the account model.
https://preview.redd.it/t1j6anf8f3151.png?width=1601&format=png&auto=webp&s=33bd141d8f2136a6f32739c8cdc7aae2e04cbc47

Nakamoto consensus

In the Bitcoin network, anyone can join the network and become a bookkeeping service provider i.e., a validator. All validators are allowed in the race to become the block producer for the next block, yet only the first to complete a computationally heavy task will win. This feature is called Proof of Work (PoW).
The probability of any single validator to finish the task first is equal to the percentage of the total network computation power, or hash power, the validator has. For instance, a validator with 5% of the total network computation power will have a 5% chance of completing the task first, and therefore becoming the next block producer.
Since anyone can join the race, competition is prone to increase. In the early days, Bitcoin mining was mostly done by personal computer CPUs.
As of today, Bitcoin validators, or miners, have opted for dedicated and more powerful devices such as machines based on Application-Specific Integrated Circuit (“ASIC”).
Proof of Work secures the network as block producers must have spent resources external to the network (i.e., money to pay electricity), and can provide proof to other participants that they did so.
With various miners competing for block rewards, it becomes difficult for one single malicious party to gain network majority (defined as more than 51% of the network’s hash power in the Nakamoto consensus mechanism). The ability to rearrange transactions via 51% attacks indicates another feature of the Nakamoto consensus: the finality of transactions is only probabilistic.
Once a block is produced, it is then propagated by the block producer to all other validators to check on the validity of all transactions in that block. The block producer will receive rewards in the network’s native currency (i.e., bitcoin) as all validators approve the block and update their ledgers.

The blockchain

Block production

The Bitcoin protocol utilizes the Merkle tree data structure in order to organize hashes of numerous individual transactions into each block. This concept is named after Ralph Merkle, who patented it in 1979.
With the use of a Merkle tree, though each block might contain thousands of transactions, it will have the ability to combine all of their hashes and condense them into one, allowing efficient and secure verification of this group of transactions. This single hash called is a Merkle root, which is stored in the Block Header of a block. The Block Header also stores other meta information of a block, such as a hash of the previous Block Header, which enables blocks to be associated in a chain-like structure (hence the name “blockchain”).
An illustration of block production in the Bitcoin Protocol is demonstrated below.

https://preview.redd.it/m6texxicf3151.png?width=1591&format=png&auto=webp&s=f4253304912ed8370948b9c524e08fef28f1c78d

Block time and mining difficulty

Block time is the period required to create the next block in a network. As mentioned above, the node who solves the computationally intensive task will be allowed to produce the next block. Therefore, block time is directly correlated to the amount of time it takes for a node to find a solution to the task. The Bitcoin protocol sets a target block time of 10 minutes, and attempts to achieve this by introducing a variable named mining difficulty.
Mining difficulty refers to how difficult it is for the node to solve the computationally intensive task. If the network sets a high difficulty for the task, while miners have low computational power, which is often referred to as “hashrate”, it would statistically take longer for the nodes to get an answer for the task. If the difficulty is low, but miners have rather strong computational power, statistically, some nodes will be able to solve the task quickly.
Therefore, the 10 minute target block time is achieved by constantly and automatically adjusting the mining difficulty according to how much computational power there is amongst the nodes. The average block time of the network is evaluated after a certain number of blocks, and if it is greater than the expected block time, the difficulty level will decrease; if it is less than the expected block time, the difficulty level will increase.

What are orphan blocks?

In a PoW blockchain network, if the block time is too low, it would increase the likelihood of nodes producingorphan blocks, for which they would receive no reward. Orphan blocks are produced by nodes who solved the task but did not broadcast their results to the whole network the quickest due to network latency.
It takes time for a message to travel through a network, and it is entirely possible for 2 nodes to complete the task and start to broadcast their results to the network at roughly the same time, while one’s messages are received by all other nodes earlier as the node has low latency.
Imagine there is a network latency of 1 minute and a target block time of 2 minutes. A node could solve the task in around 1 minute but his message would take 1 minute to reach the rest of the nodes that are still working on the solution. While his message travels through the network, all the work done by all other nodes during that 1 minute, even if these nodes also complete the task, would go to waste. In this case, 50% of the computational power contributed to the network is wasted.
The percentage of wasted computational power would proportionally decrease if the mining difficulty were higher, as it would statistically take longer for miners to complete the task. In other words, if the mining difficulty, and therefore targeted block time is low, miners with powerful and often centralized mining facilities would get a higher chance of becoming the block producer, while the participation of weaker miners would become in vain. This introduces possible centralization and weakens the overall security of the network.
However, given a limited amount of transactions that can be stored in a block, making the block time too longwould decrease the number of transactions the network can process per second, negatively affecting network scalability.

3. Bitcoin’s additional features

Segregated Witness (SegWit)

Segregated Witness, often abbreviated as SegWit, is a protocol upgrade proposal that went live in August 2017.
SegWit separates witness signatures from transaction-related data. Witness signatures in legacy Bitcoin blocks often take more than 50% of the block size. By removing witness signatures from the transaction block, this protocol upgrade effectively increases the number of transactions that can be stored in a single block, enabling the network to handle more transactions per second. As a result, SegWit increases the scalability of Nakamoto consensus-based blockchain networks like Bitcoin and Litecoin.
SegWit also makes transactions cheaper. Since transaction fees are derived from how much data is being processed by the block producer, the more transactions that can be stored in a 1MB block, the cheaper individual transactions become.
https://preview.redd.it/depya70mf3151.png?width=1601&format=png&auto=webp&s=a6499aa2131fbf347f8ffd812930b2f7d66be48e
The legacy Bitcoin block has a block size limit of 1 megabyte, and any change on the block size would require a network hard-fork. On August 1st 2017, the first hard-fork occurred, leading to the creation of Bitcoin Cash (“BCH”), which introduced an 8 megabyte block size limit.
Conversely, Segregated Witness was a soft-fork: it never changed the transaction block size limit of the network. Instead, it added an extended block with an upper limit of 3 megabytes, which contains solely witness signatures, to the 1 megabyte block that contains only transaction data. This new block type can be processed even by nodes that have not completed the SegWit protocol upgrade.
Furthermore, the separation of witness signatures from transaction data solves the malleability issue with the original Bitcoin protocol. Without Segregated Witness, these signatures could be altered before the block is validated by miners. Indeed, alterations can be done in such a way that if the system does a mathematical check, the signature would still be valid. However, since the values in the signature are changed, the two signatures would create vastly different hash values.
For instance, if a witness signature states “6,” it has a mathematical value of 6, and would create a hash value of 12345. However, if the witness signature were changed to “06”, it would maintain a mathematical value of 6 while creating a (faulty) hash value of 67890.
Since the mathematical values are the same, the altered signature remains a valid signature. This would create a bookkeeping issue, as transactions in Nakamoto consensus-based blockchain networks are documented with these hash values, or transaction IDs. Effectively, one can alter a transaction ID to a new one, and the new ID can still be valid.
This can create many issues, as illustrated in the below example:
  1. Alice sends Bob 1 BTC, and Bob sends Merchant Carol this 1 BTC for some goods.
  2. Bob sends Carols this 1 BTC, while the transaction from Alice to Bob is not yet validated. Carol sees this incoming transaction of 1 BTC to him, and immediately ships goods to B.
  3. At the moment, the transaction from Alice to Bob is still not confirmed by the network, and Bob can change the witness signature, therefore changing this transaction ID from 12345 to 67890.
  4. Now Carol will not receive his 1 BTC, as the network looks for transaction 12345 to ensure that Bob’s wallet balance is valid.
  5. As this particular transaction ID changed from 12345 to 67890, the transaction from Bob to Carol will fail, and Bob will get his goods while still holding his BTC.
With the Segregated Witness upgrade, such instances can not happen again. This is because the witness signatures are moved outside of the transaction block into an extended block, and altering the witness signature won’t affect the transaction ID.
Since the transaction malleability issue is fixed, Segregated Witness also enables the proper functioning of second-layer scalability solutions on the Bitcoin protocol, such as the Lightning Network.

Lightning Network

Lightning Network is a second-layer micropayment solution for scalability.
Specifically, Lightning Network aims to enable near-instant and low-cost payments between merchants and customers that wish to use bitcoins.
Lightning Network was conceptualized in a whitepaper by Joseph Poon and Thaddeus Dryja in 2015. Since then, it has been implemented by multiple companies. The most prominent of them include Blockstream, Lightning Labs, and ACINQ.
A list of curated resources relevant to Lightning Network can be found here.
In the Lightning Network, if a customer wishes to transact with a merchant, both of them need to open a payment channel, which operates off the Bitcoin blockchain (i.e., off-chain vs. on-chain). None of the transaction details from this payment channel are recorded on the blockchain, and only when the channel is closed will the end result of both party’s wallet balances be updated to the blockchain. The blockchain only serves as a settlement layer for Lightning transactions.
Since all transactions done via the payment channel are conducted independently of the Nakamoto consensus, both parties involved in transactions do not need to wait for network confirmation on transactions. Instead, transacting parties would pay transaction fees to Bitcoin miners only when they decide to close the channel.
https://preview.redd.it/cy56icarf3151.png?width=1601&format=png&auto=webp&s=b239a63c6a87ec6cc1b18ce2cbd0355f8831c3a8
One limitation to the Lightning Network is that it requires a person to be online to receive transactions attributing towards him. Another limitation in user experience could be that one needs to lock up some funds every time he wishes to open a payment channel, and is only able to use that fund within the channel.
However, this does not mean he needs to create new channels every time he wishes to transact with a different person on the Lightning Network. If Alice wants to send money to Carol, but they do not have a payment channel open, they can ask Bob, who has payment channels open to both Alice and Carol, to help make that transaction. Alice will be able to send funds to Bob, and Bob to Carol. Hence, the number of “payment hubs” (i.e., Bob in the previous example) correlates with both the convenience and the usability of the Lightning Network for real-world applications.

Schnorr Signature upgrade proposal

Elliptic Curve Digital Signature Algorithm (“ECDSA”) signatures are used to sign transactions on the Bitcoin blockchain.
https://preview.redd.it/hjeqe4l7g3151.png?width=1601&format=png&auto=webp&s=8014fb08fe62ac4d91645499bc0c7e1c04c5d7c4
However, many developers now advocate for replacing ECDSA with Schnorr Signature. Once Schnorr Signatures are implemented, multiple parties can collaborate in producing a signature that is valid for the sum of their public keys.
This would primarily be beneficial for network scalability. When multiple addresses were to conduct transactions to a single address, each transaction would require their own signature. With Schnorr Signature, all these signatures would be combined into one. As a result, the network would be able to store more transactions in a single block.
https://preview.redd.it/axg3wayag3151.png?width=1601&format=png&auto=webp&s=93d958fa6b0e623caa82ca71fe457b4daa88c71e
The reduced size in signatures implies a reduced cost on transaction fees. The group of senders can split the transaction fees for that one group signature, instead of paying for one personal signature individually.
Schnorr Signature also improves network privacy and token fungibility. A third-party observer will not be able to detect if a user is sending a multi-signature transaction, since the signature will be in the same format as a single-signature transaction.

4. Economics and supply distribution

The Bitcoin protocol utilizes the Nakamoto consensus, and nodes validate blocks via Proof-of-Work mining. The bitcoin token was not pre-mined, and has a maximum supply of 21 million. The initial reward for a block was 50 BTC per block. Block mining rewards halve every 210,000 blocks. Since the average time for block production on the blockchain is 10 minutes, it implies that the block reward halving events will approximately take place every 4 years.
As of May 12th 2020, the block mining rewards are 6.25 BTC per block. Transaction fees also represent a minor revenue stream for miners.

Bitcoin, Bitcoin Cash, Bitcoin Gold, Bitcoin Diamond, Bitcoin Classic - what's the difference?

Bitcoin, Bitcoin Cash, Bitcoin Gold, Bitcoin Diamond, Bitcoin Classic - what's the difference?

https://preview.redd.it/8z9xdk3h75b41.png?width=1000&format=png&auto=webp&s=99f96102e7fec84116531e8981143bca1d2c3982
Bitcoin is the first cryptocurrency, and from a technical standpoint it is outdated, because it has a number of disadvantages related to the volume of data, transaction speed and scaling. Therefore, developers have created hard forks that change the rules of the protocol and the structure of blocks. Bitcoin holders received hard fork coins based on the number of bitcoins in their wallets: usually on a 1:1 basis. Let's describe each cryptocurrency in detail and conduct a comparative analysis with bitcoin.

Bitcoin Cash

It is the first and the most famous bitcoin hard fork, which appeared on August 1, 2017. Bitcoin Cash occupies the 5th position in CoinMarketCap crypto rating by capitalization. Hard Fork has many supporters in the bitcoin community who believe that it will replace the first cryptocurrency.
In the Bitcoin Cash blockchain, the block size was increased from 1 to 8 MB, which allowed more transactions to be placed in the block and, consequently, to lower the fees.

Bitcoin Gold

Launched on October 24, 2017. The idea of Bitcoin Gold is based on the protocol decentralization, which aims to prevent the dominance of large miners in the market. Equihash is used instead of the SHA-256 algorithm. The project still exists, but has not become widely known.

Bitcoin Diamond

Launched on November 24, 2017. A notable feature of this hard fork is that the creators increased the issue volume tenfold, increased the speed of transactions and reduced fees. Holders of 1 bitcoin received 10 BCD coins. In technical terms, it corresponds to its slogan "the best Bitcoin". The project, like most hard forks, was not particularly popular, but growing still.

Bitcoin Classic

The second hard fork launched on the same day as Bitcoin Cash. The algorithm was based on the EDA mechanism, which allows to protect miners from hashrate fluctuations. Since November 2017, the project is inactive, despite the support of large companies such as Coinbase, Circle and Bitstamp. Even Roger Ver, a well-known bitcoin investor, supported the project.
All of these hardforks, except Bitcoin Classic, are traded on a well-known Binance exchange. BCH is available on almost all exchanges where Bitcoin is traded. And for convenience of trade use the Trade-mate.io service. With it you can trade on multiple exchanges in a single terminal and use a trailing mechanisms to increase profit. In addition to Binance, BitMEX and Poloniex exchanges are available as well.

InvestInBlockchain - Cryptocurrencies in the Top 100 With Working Products

Bitcoin (BTC)

📷
Bitcoin is the cryptocurrency that started it all back in 2009, after the global financial crisis and subsequent bailouts of banks left many people disenfranchised with fiat currency and outdated, insecure financial infrastructure.
Today, Bitcoin is being used for peer-to-peer payments across the globe. More than that, though, it is leading the way towards a future in which financial technology is trustless, secure, resilient, and censorship resistant. Without Bitcoin, this list would not exist.

Ethereum (ETH)

📷
The platform that brought smart contracts to the blockchain, spurring a minor revolution in the cryptocurrency ecosystem. Before Ethereum, Bitcoin and its transaction-oriented design was the central focus of most blockchain projects.
After Ethereum, teams saw the value of decentralized apps (dapps) and smart contracts, and shifted their focus to compensate.
Vitalik Buterin’s Ethereum whitepaper was released in late 2013. The project itself was announced January 2014, with a crowdsale the following July. The system officially went live in July 2015.
Since then, hundreds of businesses, individuals, and blockchain projects have adopted Ethereum as their main smart contracts platform.

Ripple (XRP)

📷
Ripple is focused primarily on one thing: fast and cheap international transactions.
Current banking infrastructure has failed to evolve in the 21st century, such that it still takes 3-5 business days on average for an international transfer to be processed. With just 4 second transaction times and at a fraction of the cost of a wire transfer, Ripple’s working product is already impacting the banking sector.
The big knock against Ripple is that its native token, XRP, is completely unnecessary. Indeed, driving adoption of Ripple’s banking solutions is far easier than getting real-world adoption for XRP.
If you’re interested in seeing a discussion about how XRP adoption will occur, you might find this reddit thread worth a read. Meanwhile, all of us will just have to wait and see whether XRP adoption strategies ultimately come to fruition.

Bitcoin Cash (BCH)

📷
Bitcoin Cash was created in 2017 when the first ever hard fork of the Bitcoin blockchain took place. The split was the result of Bitcoin’s 1MB blocks filling up. Transaction speeds were declining, fees were increasing, and it became clear to the community that the current model wasn’t sustainable for scaling.
In a move that still causes cryptocurrency fights to this day, Bitcoin and Bitcoin Cash soon emerged as separate but similar projects. BCH has 8x the block size of BTC, giving it roughly 8x the transaction throughput. Its fees and transaction times are much faster, as predicted.
Learn more about Bitcoin vs Bitcoin Cash.

Stellar (XLM)

📷
The Stellar project and its associated Lumens (XLM) token was forked from the Ripple protocol in 2014. Stellar has come into its own since then, providing a blockchain connection service for fiat transactions between banks, payment systems, and people. Stellar is fast and reliable, and it works with practically no fees for the end-user.
Stellar is a payments system, meaning its job is to move money as efficiently as possible. Partnerships with banks and financial institutions were key in evaluating its status, as was the ability to actually send money using the network.
Several non-profits and commercial entities have agreed to use Stellar as part of their financial infrastructure. Recently, the team partnered with IBM and KlickEx to facilitate cross-border transactions in the South Pacific and announced an affiliate with Keybase to streamline international transactions.
Stellar also has projects being built on its network by major established entities. IBM’s blockchain division is using XLM for their payments infrastructure, for example, and the Veridium startup is working with both organizations to tokenize its carbon credits market.

Litecoin (LTC)

📷
Litecoin is a Bitcoin fork that was created in 2011 by Charlie Lee as a cheaper and faster (2.5 minute block time instead of 10) alternative to Bitcoin. This is accomplished predominantly because Litecoin uses a Scrypt hashing algorithm instead of the SHA-256 algorithm used by Bitcoin. It’s common to hear Litecoin called “digital silver” to Bitcoin’s “digital gold,” and in reality Litecoin does not really expand upon the functionality of Bitcoin in a significant way so much as it makes different tradeoffs.
That being said, it does succeed in being cheaper and faster to use than BTC, which has led to it being accepted by hundreds of merchants and thus making Litecoin one of the most widely used cryptocurrencies for digital payments.

Tether (USDT)

📷
Tether is an unusual project. Whereas most cryptocurrencies rise and fall in value, Tether was designed to stay the same, fixed at a 1:1 ratio with the U.S. dollar.
This allows users to store, send, and receive digital currencies across platforms without incurring significant losses due to value fluctuations.
The Tether stable coin sounds straightforward, but the project isn’t without controversy. USDT is supposedly backed by real USD sitting in a bank account. But in which account? Who controls it? And is Tether being used to manipulate the value of Bitcoin? It’s all part of the Tether controversy.

Monero (XMR)

📷
Released in 2014 as a fork of Bytecoin, Monero has since made a name for itself as the most popular privacy coin on the market.
Most cryptocurrencies offer little in the form of anonymity. Monero was built for privacy from the ground-up, featuring stealth addresses, ring signatures, and complete coin fungibility. All of this adds up to a near-perfect cloak of anonymity, allowing Monero users to conduct transactions without exposing their identity.
Monero has had steady growth over the years thanks to a dedicated team of developers and an active community. The project continues to evolve with new privacy features and improved transaction security.

NEO (NEO)

📷
NEO was founded in 2014 as one of the earliest smart contract platforms, giving it a wide breadth of possible functionality. The platform’s strongest use case is digitizing traditional assets so that they can be easily tracked and exchanged on the blockchain.
NEO is also well-known as the “Chinese Ethereum,” and the fact that it is a Chinese-based project does seem to make Chinese dapp developers somewhat more likely to build on top of it than other platforms.
In fact, NEO has already supported dozens of ICOs and remains one of the predominant platforms for supporting smart contracts and dapps.

Binance Coin (BNB)

📷
Binance Coin is an exchange token used to reduce trading fees on the Binance platform.
Users can opt to pay exchange, listing, and withdrawal fees using BNB and enjoy as much as a 50% discount on all charges. This turns out to be a powerful incentive for purchasing and holding BNB, as what trader doesn’t enjoy saving money on transactions?
Binance Coin is an ERC-20 token that runs on the Ethereum blockchain. Its purpose is extremely limited, but because such a vast number of Binance users transact with it every day, it qualifies as a working and active product.

Zcash (ZEC)

📷
Zcash is another immensely popular privacy coin that often cracks the top 20 cryptocurrencies. It uses the tagline “internet money” and promises to fully protect the privacy of transactions with zero-knowledge cryptography.
Zcash provides anonymity by shielding transactions on the blockchain, preventing anyone from seeing the sender, recipient, or value of each transaction. The technology is so effective the Ethereum team is investigating it to enable anonymous transactions on their network.
Zcash has grown in leaps and bounds in 2018. The dev team published a roadmap through the year 2020, which includes a major features upgrade in the October 2018 Sapling release. Coinbase is also considering listing Zcash, which is a huge boost for any cryptocurrency.

Qtum (QTUM)

📷
Qtum is a smart contracts platform similar to Ethereum, only with a stronger focus on value transfers and decentralized apps. It’s meant to be something of a hybrid between Bitcoin and Ethereum, allowing businesses to build smart contracts on the platform or just focus on cryptocurrency transactions.
Qtum launched in March 2017, and dashed straight to the top. The initial offering sold over $10 million in tokens after just 90 minutes. The project differentiated itself by providing a rare Proof-of-Stake smart contracts platform designed to compensate for some of Ethereum’s shortcomings, including lack of compatibility for mobile devices.
Qtum released its mainnet in September 2017, opening the doors to a fully functional smart contract and dapps platform. Several projects already have an established presence on the network. One of the more exciting ones is Space Chain, which aims to create an open-source satellite network anyone can use for data transmission, storage, and development.

0x Protocol (ZRX)

📷
0x Protocol has one of the most important working products in the entire Ethereum ecosystem. It is a permissionless, open-source protocol that facilitates trustless exchanges of Ethereum tokens through relayers and dapps that build on top of the protocol.
Not only has 0x been providing this functionality for over a year now, but they’ve been working to expand the protocol functionality significantly since that initial launch. In 0x protocol 2.0 and beyond, it will be possible to trade tokens built on standards besides ERC-20, including non-fungible ERC-721 tokens.
In a market full of scams and vaporware, 0x’s valuable contributions to the Ethereum ecosystem have made it one of the best performing cryptocurrencies of 2018.

Bytecoin (BCN)

📷
Bytecoin is another popular privacy-focused cryptocurrency with a strong community and user base. Transactions on the Bytecoin blockchain are instantaneous, untraceable, unlinkabe, and resistant to blockchain analysis.
Bytecoin has been around for a long time now, with contributions to the project beginning in 2012. However, that hasn’t stopped the project’s developers from continuously improving the product.
The recently updated Bytecoin roadmap has a hard fork for a consensus update scheduled for August 31, as well as numerous initiatives for community growth constantly in the works.

Decred (DCR)

📷
Founded in 2015 by former Bitcoin developers, Decred’s most important working product is its solution to Bitcoin’s biggest problem. No, not scalability… blockchain governance.
You see, early Bitcoiners have been debating block size limitations and the efficacy of other scalability solutions like the Lightning Network for years, even though the problem of scalability really only became discussed in the mainstream in 2017.
With its community-based governance model and strong adherence to the core ethos of decentralization, Decred is built to evolve and improve rapidly. That means that it’s equipped to handle not only the scalability problem today, but other big problems that might arise down the line.
When you have poor governance, it is an arduous process making any upgrades to a project, no matter how necessary they may seem to the majority of coin holders. Decred’s best-in-class and still improving governance model give it an intriguing case to be a leader in digital payments for a long time to come.

BitShares (BTS)

📷
BitShares aims to improve worldwide access to financial services via blockchain. The tagline “assist the unbanked” summarizes the project nicely. In practice, this translates to BitShares operating as a decentralized exchange, one that was built from the ground-up to avoid scalability issues and keep transaction fees low.
BitShares was launched in 2014 by Dan Larimer, who would then go on to take a lead development role in both EOS and Steem.
The current state of the project offers decentralized asset exchange, price-stable cryptocurrencies, recurring and scheduled payments, user-issued assets, and more, all available through a decentralized system powered by delegated PoS consensus.

Steem (STEEM)

📷
Steem is the cryptocurrency that powers Steemit, a decentralized social media platform that incentivizes user participation through micropayments. Think of it like Reddit, only instead of just upvoting or downvoting posts, users can actually reward creators for their effort.
Steem is a functional cryptocurrency used exclusively on the Steemit platform. That gives it something of a limited use, but seeing as how Steemit is live and boasts a few hundred thousand users, it’s hard to argue it isn’t a working product. Some people may even be earning money using Steemit.

Siacoin (SIA)

📷
Siacoin is one of the leaders in decentralized cloud storage, a more secure and affordable alternative to centralized cloud storage solutions like Amazon S3, Google Drive, iCloud, Dropbox, and others.
Sia 1.0 was launched in June 2016, and has achieved considerable adoption since then. With the $200 billion cloud storage market widely seen as one of the spaces most ripe for blockchain disruption, Sia has gotten off to a nice start by offering a functional decentralized cloud storage platform for over 2 years.

Augur (REP)

📷
Augur is one of the most recently launched products on this list. The platform mainnet went live in early July 2018, bringing to fruition almost 4 years of post-ICO work.
Augur is a decentralized prediction market that uses game theory to generate crowd-sourced insights. Essentially, thousands of people working together have shown the remarkable ability to forecast outcomes.
With Augur, users can put REP tokens as bets on these predictions, essentially creating a form of “useful social gambling.”
Augur’s release was a long time coming. The project started as far back as 2014, nearly a year before the ICO. The creators cite the complexity of Augur’s smart contracts as the chief cause of the lengthy development time.
Regardless of its past, Augur is now a live product with a bright future. Over 300 predictions have already been made, with the largest winning payout hitting $20,000. Betting volume even exceeded $1 million within the first weeks of launch.

Basic Attention Token (BAT)

📷
Basic Attention Token was one of the easiest projects to include on this list. That’s because its working product, Brave Browser, has more than 3 million active usersbetween its mobile and desktop platforms, making it one of the most widely-used working products in the blockchain space.
Not only is Brave Browser functional, it’s the only browser on the market that has built-in ad-blocking and tracker blocking, making the browsing experience both cleaner and faster than what you get with other popular browsers like Chrome and Firefox.
The future remains uncertain for the BAT token itself, as its adoption depends heavily on whether or not advertisers buy-in to the Brave model, as well as how willing Brave users are to be shown relevant ads and to pass along the BAT they earn to content publishers.
Given Brave’s success in just a short time since being launched, though, the future does appear promising for BAT.

Nano (XRB)

📷
Nano (formerly RaiBlocks) is all about scalability. The coin has nearly instant transactions with a completely fee-less structure. The platform accomplishes this by creating a unique blockchain for every account, preventing bloat and allowing for practically infinite scalability.
Nano’s motto of “do one thing and do it well” has gotten them a long way. The team doesn’t have to deal with scaling or slowdown issues thanks to the underlying structure of the project, allowing its roadmap to focus on wallet updates and outreach. This is one cryptocurrency that’s essentially feature complete, and it has been for some time.

Golem (GNT)

📷
Golem has set out to be the Airbnb of computing resources. Have you ever needed extra GPU power to finish up a render? How about processing scientific data similar to the [email protected] project?
Even if you don’t have those needs, a lot of groups do. Golem aims to provide easy access to those resources, all of which are rentable for a small cryptocurrency fee.
Golem hit the mainnet launch button in April 2018, and was met with a fair amount of fanfare. One of the main goals for the feature-incomplete launch was to push the product out so real users could put it to work.
The team was interested in strengthening their interactions with end users to help guide the future of the platform. The team has several major milestones planned for the coming months, so the mainnet release is only just the beginning.

Pundi X (NPXS)

📷
Pundi X has been shooting up the market cap rankings so far in Q3 2018, and they also happen to have a working product that just recently became available to retailers.
The primary Pundi X product is a point-of-sale (POS) device that enables quick and easy mobile transactions for both fiat and cryptocurrencies. 500 POS devices are already being used by retailers in Asia, and there are thousands more scheduled to be distributed in the coming months.
In addition, Pundi X also offers XPASS cards, cryptocurrency credit cards that can work in place of mobile apps for making digital payments.
What makes the Pundi X project noteworthy is that it enables consumers to pay retailers in cryptocurrencies like BTC and ETH, and it immediately converts the payments into local fiat currencies so that retailers don’t need to worry about price volatility of the cryptocurrencies.
This makes it significantly easier for people to use cryptocurrencies in their daily lives, making Pundi X an exciting project for blockchain enthusiasts who are looking for signs of future mass adoption.

Waves (WAVES)

📷
Waves was the first ever blockchain platform that made it possible for anybody — regardless of their programming experience — to create blockchain tokens. Additionally, Waves has a decentralized exchange where tokens can be traded and exchanged with fiat currencies.
Since the project’s first releases in 2016, Waves has gone on to make their DEX accessible from mobile phones and expanded its functionality significantly, while also building several strategic partnerships to help grow the Waves community and user base.
Ultimately, though, the Waves Client is the project’s most important working product, as it is what allows tokens to be issued, stored, sent, and exchanged among users.

KuCoin Shares (KCS)

📷
Similar to Binance Coin, KuCoin Shares is an exchange token that can be used to pay reduced fees on cryptocurrency trades. KCS has the added bonus of paying dividends to long-term hodlers, as well, paying out a 5% ROI for most users.
The nature of KuCoin Shares is one of the reasons the KuCoin exchange has gotten so much attention since it appeared on the scene. The tokens themselves are limited in scope, of course, but the sheer number of people using them for trades and buying them for passive income is enormous.

Wanchain (WAN)

📷
Wanchain aims to build new and improved financial infrastructure to seamlessly connect the digital economy through blockchain interoperability. The use cases for Wanchain’s network are vast, and they include decentralized financial services, supply chain logistics, medical data sharing and security, digital ID management, and more.
With the recently released Wanchain 2.0, it is now possible to transfer Ether cross-chain using Wanchain’s Ethereum Mapping Token, WETH.
Ethereum interoperability is just the start, though, and it’s expected that cross-chain support for Bitcoin and a couple of ERC-20 tokens will follow before the end of 2018.

Komodo (KMD)

📷
Komodo is a fork of Zcash that uses the same zk-snark cryptography to hide information about transaction participants and amounts being sent. Functional privacy coins aren’t unique (there are a handful on this list) but Komodo does have some unique features.
For one, Komodo was the first ever decentralized initial coin offering. Moreover, Komodo helps other developers to build their own customizable blockchain solutions, from building and securing independent blockchains and launching decentralized ICOs, to integrating projects into the cryptocurrency ecosystem.
KMD would already qualify as a working product for its anonymity features on digital payments, but add the end-to-end blockchain building solution and it’s clear that Komodo is making meaningful contributions to the cryptocurrency ecosystem.

Ardor (ARDR)

📷
Ardor is a scalable blockchain platform that allows businesses to create their own child chains and tokens with relative ease. This helps keep blockchain bloat to a minimum and provides multiple transactional tokens without sacrificing core chain transactions. It’s also a remarkably energy efficient platform that uses Proof-of-Stake to power consensus.
Ardor launched its mainnet on January 1, 2018 after a full year in testnet status. Its core features are largely in place, with the roadmap set to improve things like scalability and snapshotting.
The Blockchain-as-a-Service-platform hosts a few projects of its own, including the Ignis ICO, which was the first child chain on the mainnet.

Huobi Token (HT)

📷
Huobi is a digital asset exchange platform founded back in 2013, now offering well over 250 different trading pairs. The Huobi Token, meanwhile, is an ERC-20 token that is used on the exchange for discounts on trading fees of up to 50%.
In addition, 20% of the income generated on the Huboi Pro trading platform is used to buy back HT on the open market.
Unlike most buyback programs, the main purpose of Huobi’s program isn’t to reduce the circulating supply of HT. Rather, the HT that is bought back goes into a Huobi Investor Protection Fund, which is used to compensate Huobi users if they lose coins or tokens on the platform, as well as to ensure market stability and protect investor interests.

ZenCash (ZEN)

📷
ZenCash is yet another privacy coin with a working product in the Top 100, originally launched in the first half of 2017.
What makes ZenCash unique is that it’s the first blockchain with Transport Layer Security (TLS) integration for node encryption, making communication on the ZenCash network both private and highly secure.
Some other interesting parts of the ZenCash product include Tor nodes and built-in chat messaging services. In the future, the ZenCash team will deliver a DAO Treasury Protocol-level Voting System as well as a scalability solution to handle greater transaction volume.

PIVX (PIVX)

📷
PIVX is another privacy coin that focuses on keeping users and their associated transactions hidden under a cloak of secrecy. The project also tries to keep transactions as fast and fee-less as possible, something not all privacy platforms can boast about.
PIVX launched in January 2016. The coin is currently spendable and delivers the privacy features it promises, though it’s not yet a widely accepted currency by merchants.
Future plans for PIVX include governance functions to engage the community, wallet voting, and its own zPIV decentralized exchange.

Kyber Network (KNC)

📷
Kyber Network launched their mainnet in Q1 2018, enabling instantaneous and secure inter-token settlements through a Decentralized Liquidity Network.
It’s currently possible to swap ERC-20 tokens on the network with just a few mouse clicks, giving it some basic functionality that is already being used to improve liquidity for Ethereum tokens.
In the future, however, Kyber Network will expand its functionality significantly in an effort to seamlessly connect dapps, DEXes, protocols, payment systems, token teams, investors, fund managers, and digital wallets.

Bancor (BNT)

📷
Bancor is a liquidity provider that enables users to exchange tokens without the need for a third-party to be involved in financing the transaction.
Gaining liquidity is incredibly important for young cryptocurrency projects, as a lack of liquidity makes it risky for investors to buy a considerable amount of a given coin or token, knowing that it might be exceedingly difficult to sell should they wish to.
Bancor’s technology makes it possible to convert one token to another, so that investors can be confident that they won’t be stuck involuntarily holding a cryptocurrency that they want to sell. This functionality makes the Bancor Liquidity Network one of the most promising working products on this list, and one that has already achieved a good deal of adoption.

Loom Network (LOOM)

📷
Loom Network is still less than a year old, having been founded in October 2017. However, they have accomplished a lot in that short time span, including having launched numerous tools to help software developers learn how to build blockchain solutions.
The most important of these tools — and Loom’s biggest working product — is the Loom software development kit (SDK).
However, Loom Network is far more than just a simple blockchain coding academy. It is also a production-ready scalability solution for Ethereum, as the Loom developer toolkit helps programmers to build highly scalable dapps which connect to the Ethereum blockchain through special side chains called DappChains.
The project may still be in its infancy, but Loom Network is already contributing more utility to the cryptocurrency ecosystem than the vast majority of other cryptocurrency projects.

Polymath (POLY)

📷
Polymath wants to be the world’s go-to resource for security tokens on the blockchain. What Ethereum did for tokens, Polymath will do for securities.
The advantages of this are enormous, but the Polymath team likes to point to 24/7 market access, the elimination of middlemen, and trading access for 2 billion unbanked people around the world as the chief benefits of their efforts.
The Polymath platform launched in October 2017, and has since released a new security token every week, attracting investors and traders alike. It’s not as exciting of a project as some other blockchain tech, but it’s delivering on its promises with a working product.

Bibox Token (BIX)

📷
Bibox is a encrypted digital asset exchange whose primary differentiator from other crypto exchanges is that it integrates AI technology.
The purpose of the AI is to help Bibox’s traders, which it does by providing quantitative computation and analysis of trading activity, personalized risk allocation strategy, speech recognition, and objective analysis of the various coins and tokens listed on the exchange.
The Bibox exchange first launched back in November 2017. It has operation centers in the US, Canada, mainland China, Hong Kong, Japan, and Estonia. BIX token holders receive 20% of the exchange profits, and also get discounts on trading fees, similar to Binance.
