Decred is a cryptocurrency designed for P2P payments in a similar vein as Bitcoin, albeit with a focus on governance through a hybrid PoW/PoS consensus architecture. While not a fork of Bitcoin, Decred utilizes several of its design elements and explicitly aims to improve upon Bitcoin’s perceived shortcomings. Decred emphasizes governance input for all stakeholders through an on-chain voting and public proposal system; it was the first blockchain to implement an on-chain, token holder-approved hard fork.
Tether, a cryptocurrency based on the Bitcoin blockchain, is the most widely known stablecoin functioning today.

Litecoin is a cryptocurrency emphasizing rapid transactions and low fees, released in 2011 by Charlie Lee as an early fork of Bitcoin. Lee modified three key parameters of the original Bitcoin design: reducing the target block confirmation time to 2.5 minutes, increasing the total supply to 84 million LTC, and implementing the memory-hard PoW algorithm Scrypt. This consensus algorithm is ASIC-resistant, reducing the risk of centralized mining infrastructure. In other respects, the Litecoin network is similar to Bitcoin. Litecoin is designed to be used as a rapidly processed medium of exchange for everyday transactions, and was one of the first major cryptocurrencies to implement Segregated Witness in mid-2017.
While the appearance of Venezuela’s Petro attracted considerable attention to the issue of state-backed cryptocurrencies, little discussion has explored the forms these are likely to take, the impacts they are likely to have, and the broad, long-term impacts likely to result.
