Comparison of cryptocurrencies

The cryptocurrency market is explosive which currently serves hundreds of currencies. Almost all of them are obvious scams—including many which purport to have a large market cap. This article aims to list only the most relevant cryptocurrencies in terms of novel technological advancements or strong engineering teams, or due to widespread awareness thereof. Direct, low-level scams should not be listed here.

Bitcoin Cash.pngBitcoin Cash BCH 2017-08-01 Low An altcoin based on Bitcoin’s blockchain with replay protection and an increased block size limit of 8MB. An unusual emergency difficulty adjustment algorithm causes significant periods of hyperinflation.
Namecoin1.pngNamecoin NMC 2011-04-18 Low First cryptocurrency that implemented Satoshi’s BitDNS idea. Essentially the first real altcoin. Still under active development. First merged-mined altcoin.
Dash.pngDash DASH 2014-01-18 Low Introduced the X11 algorithm, which is just a composite function of multiple hashing algorithms. Had a significant failure mode in the beginning which equated to a majority premine by a small number of Amazon EC2 customers. This means their Master Node algorithm has been in a failure mode from the beginning. dash.orh
Ethereum.pngEthereum ETH 2015-08-07 Low Majority premine sale. Source of the ICO bubble. Multiple client implementations which fail against each other in terms of consensus errors regularly. Requires multiple months of time to sync to eth blockchain. Contract-building tools interpret input incompatibly.
Ethereum Classic-32x32.pngEthereum Classic ETC 2016-07-24 Low An altcoin of Ethereum which split from ETH’s blockchain when the DAO was hardforked to refund the Ethereum Foundation’s members’ money, including to Roger Ver.
Litecoin.pngLitecoin LTC 2011-10-07 Low Originally meant to be a CPU-friendly “silver” to Bitcoin’s “gold”, the early SCRYPT parameters, it was discovered later, led directly to GPU, and then ASIC-mining almost from the start.
Monero.pngMonero XMR 2014-04-18 Medium The most successful implementation derived from the Cryptonote codedrop. Uses Ring Confidential Transactions.
Zcash-16x16.pngZcash ZEC 2016-10-28 Medium First cryptocurrency that implemented the zerocash protocol. Large “Founder’s Reward” which is paid out over the first few years of mining.
Zcoin-800x800.pngZcoin XZC 2016-09-28 Medium First cryptocurrency that implemented the zerocoin protocol which also makes it the first useful Zero-knowledge proof based anonymous cryptocurrency. First that implements Merkle Tree Proof of Work (MTP).
