Website: https://bitcoin.org/en/

Bitcoin is the world’s first cryptocurrency, described on 2008 by an unknown person or a group called Satoshi Nakamoto.

The purpose of Bitcoin is to become an alternative to traditional payment solutions, offering worldwide payments incredibly fast and cheap, without having a central authority, like the bank, controlling the transactions. Instead it is controlled by computers around the world who validate all of the transactions in a P2P (Peer to Peer) fashion.

A lot of people have heard about Bitcoin, but have never heard about other cryptocurrencies. Many people treat Bitcoin and cryptocurrency as synonyms.

There’s a finite number of Bitcoins – 21,000,000BTC. They are being mined and it’s calculated that the last Bitcoin will be mined on 2140.

The first real world Bitcoin transaction happened on May 2010, when Laszlo Hanyecz bought 2 pizzas for 10,000BTC.

Bitcoin’s team has developed a concept called Lightning Network that will hopefully solve the scalability problems as well as high fees and slow speeds;

While the information about the users is kept secret, the history of Bitcoin transactions is completely transparent, and everyone can see the amounts sent.

Bitcoin mining uses enough energy annually to power almost 4,000,000 average US households

  • Ethereum [ETH]

Ethereum is one of the top cryptocurrencies, proposed by Vitalik Buterin on 2013, as a next step in cryptocurrencies and blockchain. Ethereum is a blockchain-based, open-source smart contract platform. While the early cryptocurrencies, like Bitcoin, had only one functionality, P2P payments, Ethereum allows users to create smart contracts, issue their own tokens and run decentralized apps (DApps), making it possible to do a lot more things on the blockchain than before. Ethereum’s open-source nature means that anyone can take the source code and build off of it.

Smart contracts are basically programs that run on the blockchain and they make it possible for people to issue their own cryptocurrencies, launch ICOs (initial coin offerings), create apps that run on the blockchain and even automated companies, capable of functioning without human intervention. Interesting facts

  • Ripple [XRP]

Coinmarketcap: https://coinmarketcap.com/currencies/ripple/

Website: https://ripple.com/

Ripple is the world’s first enterprise blockchain solution for global payments. It connects banks, payment providers, digital asset exchanges and corporates through its network to provide frictionless global payments.

Instead payments going through multiple banks when making an international payment (which could take days to finally be confirmed and are quite expensive), the transaction will go through the Ripple network. This means that all transactions take place directly between the sender’s and recipient’s banks, making the process a lot cheaper and faster.

One thing to note is that Ripple can mean three separate things. There’s the Ripple platform for payments, then there’s Ripple, the company that manages the Ripple platform, and finally there’s Ripple [XRP], the native currency of the Ripple network. That’s a lot to digest!

Ripple doesn’t use Proof-of-Work to validate transactions. Running a Ripple node for validating transactions is not open to everybody like it is with most cryptocurrencies. Ripple chooses the nodes they trust to process these transactions. This means it’s not truly decentralized like all of the other cryptocurrencies, but on the other hand, it makes the transactions a lot faster.

  • Bitcoin Cash [BCH]

Website: https://www.bitcoincash.org/

Coinmarketcap: https://coinmarketcap.com/currencies/bitcoin-cash/

Bitcoin Cash is a Bitcoin hard-fork that happened on the 1st of August, 2017. The fork was initiated because of the scalability issues of the classic Bitcoin. Bitcoin Cash changed the size of the blocks from 1MB to 8MB, making it possible to process roughly around 60 transactions per second, compared to the 7 transactions per second of the classic Bitcoin, including the SegWit update. It also has lower transaction fees, compared to Bitcoin.

In addition, Bitcoin Cash didn’t integrate the Segregated Witnesses (SegWit) protocol, it has a stronger protection against replay attacks, and the difficulty of the block mining is adjusted faster than with Bitcoin.

One main problem with Bitcoin Cash is that the increased block size makes it difficult for smaller miners (computers) to contribute, because they are not able to process this amount of data. The size of Bitcoin Cash’s block sizes are 8MB compared to Bitcoin’s 1MB and both have 10 minute block times, so every 10 minutes there is eight times more information saved on Bitcoin Cash’s blockchain, making it faster than the traditional Bitcoin blockchain. This could mean over 1GB of new data every day.

Interesting facts:

Bitcoin Cash is the first successful Bitcoin hard-fork.

Bitcoin Cash’s transactions are currently 100x’s cheaper than Bitcoin transactions.

  • Cardano [ADA]

Philosophy: https://www.cardanohub.org/en/philosophy/

Website: https://www.cardanohub.org/en/home/

Coinmarketcap: https://coinmarketcap.com/currencies/cardano/

Cardano is considered a 3rd generation cryptocurrency, led by one of the founders of Ethereum, Charles Hoskinson. Cardano is a smart contract platform like Ethereum, but takes the idea to a new level by trying to solve issues with scalability, interoperability and sustainability of current cryptocurrencies. It is labelled as the first blockchain project that is based on scientific philosophy and built on academic research that has gone through detailed academic review and analysis.

Cardano is building its platform with both end-users and regulators in mind, by trying to find the middle ground between regulations, privacy and decentralization. The platform uniquely uses Haskel programming language that offers high degree of fault tolerance, which ensures that the code stays relevant and usable in the future.

Cardano is built on two layers – one is for registering the movement of ADA and the other one is for running smart contracts, which means more flexibility and security. Cardano is using their own Proof-of-Stake algorithm called Ouroboros, which will make transactions a lot faster as well as eliminating the need of storing the whole blockchain on every node. Ouroboros instead generates leader nodes who push the transactions.

  • Litecoin [LTC]

Whitepaper: As Litecoin started off as a clone of Bitcoin, they haven’t written a whitepaper

Coinmarketcap: https://coinmarketcap.com/currencies/litecoin

Website: https://litecoin.org/

Litecoin is a cryptocurrency that like Bitcoin, offering peer-to-peer, near-instant, and almost zero cost payments to anyone in the world. Created by Charlie Lee who has worked for Google and Coinbase, Litecoin is an open source global payment network that is fully decentralized without any central authority. The network is secured by cryptography and empowers individuals to control their own finances.

Litecoin was inspired by Bitcoin and in technical details is nearly identical to the ‘King of Cryptocurrencies’. The main differences between Litecoin and Bitcoin are in the confirmation time and the consensus algorithm used.

Historically, the average confirmation time for a Bitcoin transaction has been around 10 minutes, while Litecoin boasts an average confirmation time of 2.5 minutes.

While Bitcoin uses the longstanding SHA-256 consensus algorithm, Litecoin uses a relatively new algorithm called Scrypt. The main difference in these algorithms is in the mining of coins. Bitcoin miners can use dedicated and efficient mining machines called ASICs, while Litecoin can’t be mined with ASICs, encouraging mining with traditional CPUs and GPUs, making mining more accessible.

Interesting facts:

Litecoin is called the silver to Bitcoin’s gold.

At the end of 2017 Charlie Lee sold all of his LTC, as he was often accused of using his strong influence on social media to manipulate the price of LTC for his own benefit.

Litecoin is able to handle higher transaction volume. The network is thus planned to produce 84 million Litecoins, which are four times as many currency units as Bitcoin.

Like Bitcoin, Litecoin has also integrated the SegWit protocol, mainly because it allows Lightning Network (LN) to be built on top of it.

In February 2018, Litecoin had a hard-fork and Litecoin Cash was created. Litecoin Cash moved from Scrypt algorithm back to SHA-256 algorithm, and the founders expect to become faster than the original Litecoin in the future

  • NEO [NEO]

NEO is a blockchain platform and cryptocurrency which enables the development of digital assets and smart contracts. The project was founded by Da Hongfei in 2014 in China. The project was initially under the name of AntShares, but later it was renamed to NEO. 

Interesting facts:

  • NEO is often called “Chinese Ethereum”;
  • NEO is partnered with a company called OnChain which has extensive experience in integrating blockchain to businesses;
  • While Ethereum only supports their own programming language – Solidity; NEO supports most of the common programming languages around, like C, C++, C#, JavaScript, Java and Python;
  • NEO is essentially developing their platform to be quantum computer proof;
  • The fact that China acts quite independently from the West shows that Chinese companies like Alibaba, WeChat and NEO can become hugely successful even if there are already more successful and established counterparts from the West;
  • NEO is currently not a distributed blockchain, which means that, while it is decentralized, it is only operated on a few nodes, which are all controlled by NEO itself. But during 2018 they have promised to start distributing the network;
  • The cost of launching a smart contract on NEO is quite expensive – over $10,000USD.

  • Stellar [XLM]

Stellar is an open-source protocol for exchanging money founded by Jed McCaleb and Joyce Kim in early 2014. Stellar was initially based on Ripple systems, with the aim of redesigning the global economy for more inclusiveness. But citing the complexity of the system, Stellar later redesigned itself with a brand new system of its own.

Interesting facts:

  • The native asset of Stellar is called Lumens [XLM];
  • One of the major partners with Stellar is IBM;
  • While Ripple is developed by ex-bankers and financial professionals, Stellar is built by start-up veterans, like WordPress founder Matt Mullenweg and Y-Combinator President Sam Altman;
  • Jeb McCaleb, co-founder of Stellar, and also a co-founder of Ripple, was banished from Ripple before creating Stellar, but he still receives payments from the company;

  • Monero [XMR]

Monero is an open-source cryptocurrency created in April 2014 that focuses on privacy and decentralization. Monero aims to improve on existing cryptocurrency design by obscuring sender, recipient and amount of every transaction made as well as making the mining process more equal.

Interesting facts:

  • Monero’s focus on privacy has attracted many people who are interested in evading the law. Its egalitarian mining process is also used by hackers who embed mining code into websites and apps.
  • Monero uses Ring Signatures, Stealth Addresses and Ring Confidential Transactions to provide its users with maximum privacy.
  • Monero is often associated with Darknet and illegal activities because of its enhanced anonymity and privacy.

  • EOS [EOS]

EOS is a blockchain-based, decentralized operating system, designed to support commercial-scale decentralized applications by providing all of the necessary core functionality, enabling businesses to build blockchain applications in a way similar to web-based applications.

Interesting facts:

  • “EOS” is not an officially defined acronym, but the community has given it many different names like, “Ethereum On Steroids”, “End Of Silence”, “Endless Online Scaling”, and even “EOS Operating System”.
  • EOS distributes its tokens during a 341-day ICO, which has an entirely novel structure. The ICO is divided into 350 23-hour long windows, in every window 2,000,000EOS tokens will be distributed amongst investors at market price.
  • The first 5 days of EOS’s ICO were done “traditionally”, during which EOS raised around $185M in ETH.
  • Running an EOS node requires Linux/OS X operating system.

  • Dash [DASH]

Dash is a peer-to-peer open-source cryptocurrency like Bitcoin, acting as digital cash that can be sent without the need for middlemen like the bank. Dash was created by Evan Duffield and launched on the 18th of January, 2014 as a fork of Litecoin. The coin started off under the name XCoin, later to be renamed to Darkcoin, and was finally rebranded to Dash (derivative of “Digital” and “Cash”).

Interesting facts:

  • Dash is classified as a DAO (decentralized autonomous organization) because of its self-governance practice;
  • Within the first 48 hours from the creation of the coin around 1.9 million or approximately 10% of the total supply of the coins were mined. This mishap happened because of a bug in the difficulty parameters in the code when Litecoin was forked to create Dash. The problem was quickly fixed.
  • Dash uses two-tier The first tier consists of regular miners who confirm the transactions, and the second tier consists of MasterNodes that perform InstantSend, PrivateSend and governance functions.
  • Running a MasterNode costs an initial payment of 1000 DASH;
  • Dash’s partnership with Coinapult makes it possible to buy Dash with over 20 different fiat currencies.

  • IOTA [MIOTA]

IOTA is a next generation public distributed ledger that, unlike other cryptocurrencies that utilize blockchain, utilizes a novel technological approach, called the “Tangle”. The Tangle is a new data structure based on a Directed Acyclic Graph (DAG).

Interesting facts:

  • IOTA was founded in 2014 as a German non-profit organization;
  • IoT devices have been regarded as the 4th industrial revolution, as it opens up never before seen opportunities, and IOTA is positioning itself as a critical factor to make IoT revolution happen;
  • In November 2017, Microsoft’s Blockchain specialist, Omkar Naik was quoted saying that Microsoft will partner with IOTA, which was later proven to not be the case;
  • In December of 2017 the price of IOTA skyrocketed from around $1 to $5 in a matter of a week, as IOTA announced partnerships with Samsung and Fujitsu.

  • NEM [XEM]

New Economy Movement (NEM) is an enterprise-grade solution to power the impending blockchain economy, focusing on creating a smart asset blockchain which could effectively work under heavy workloads. Originally NEM was intended to be a fork of NXT, but the community decided to go with a completely new code. The alpha release was launched on June 25, 2014 and the full version was launched on March 31, 2015.

Interesting facts:

  • The idea behind NEM was started by a Bitcointalk forum user called UtopianFuture, and the developers of NEM are keeping themselves pseudonymous.
  • The launch of the currency was not a smooth road. People who held the NEMstake asset or signed up to Bitcointalk forum to receive their coins did not receive them, instead the coins;
  • To run a booted and synchronized node a harvester must hold at least 10,000 NEM;
  • At the start of 2018, over $500 million in NEM was stolen from a Tokyo-based cryptocurrency exchange Coincheck.
