Feathercoin is a PoW coin with a fast block processing time. The project was developed with the goal of creating a user friendly coin with fast transaction times and low fees. The Feathercoin network features Automatic Checkpointing (ACP), which is used to prevent 51% attacks. ACP creates a new checkpoint every 5 blocks, protecting the history of the Feathercoin blockchain.

BurstCoin is a cryptocurrency with a Proof-of-Capacity (PoC) consensus algorithm. Unlike most other cryptocurrencies, Burst's architecture uses a Tangle (similar to IOTA) instead of relying on a blockchain. It also utilizes ring signatures and other features, in what is called the Dymaxion. The Dymaxion implements layers of tangle-based lightning networks on top of the Burst blockchain. Each of these payment channels is opened in the form of a standalone colored tangle. Burst is also developing atomic cross-chain transactions (ACCT), that will allow for full decentralized trading between two cryptocurrencies.

Bitcoin Cash SV is a cryptocurrency that was created as a result of a hard fork of the Bitcoin Cash blockchain that occurred on November 15, 2018. The central issue that led to the hard fork of Bitcoin Cash was a debate among prominent members of the Bitcoin Cash community regarding block size. A larger block size can improve transaction times, but also lead to greater network centralization. Roger Ver, an influential cryptocurrency advocate, was one of the central figures in favor of keeping the smaller 32 MB block size, while Craig Wright, the chief scientist at nChain, favored a larger 128 MB block size. The division between these two factions led to the hard fork that created Bitcoin Cash ABC and Bitcoin Cash SV.
