peercoin-sha256-crypto

Sustainable. Secure. Peercoin is here. Through an innovative minting algorithm, the Peercoin network consumes far less energy, maintains stronger security, and rewards users in more sustainable ways than other cryptocurrencies. Peercoin’s original innovation is the proof-of-stake/proof-of-work hybrid system. Like other cryptocurrencies, initial coins can be mined, but the core network is maintained by coin holders, rather than the fastest pool. Maintaining the network through the hybrid proof-of-work/proof-of-stake algorithm reduces the risk of the Selfish-Miner Flaw, 51% attacks, and the block bloating that have been used to exploit other currencies.

opensourcecoin-sha-256-crypto

OpenSourceCoin (OSC) is a SHA 256 POW/POS cryptocurrency. It has features like Symmetrically Scaling Difficulty retarget algorithm that set it apart from other cryptocurrencies. While being a proof of stake coin in the vein of P2Pcoin, OSC is different in many ways. It utilizes payment notes, called Transaction or “Tx Messages” to pass notes to other addresses within the blockchain. A checkpointing server is responsible for maintaining blockchain security to reduce the risk of a “time travel exploit”, a method of reversing transactions in a hash-cash proof of work environment first described and later carried out by ArtForz of the bitcoin community.
