Novacoin is a hybrid Proof of work (POW) / Proof of stake (POS) decentralized peer-to-peer cryptocurrency.The Proof of Work part of Novacoin is based on the Scrypt hashing algorithm. Proof of Stake contributes to the coins energy efficiency, as there is no need for nodes to contribute mining power to part of the money creation process. As of now, Novacoin is set to be capped at 2 billion coins. However Novacoin stated that the cap limit may be lifted if the situation requires it. It looks very much like a variation of Sunny King Peercoin.
Standard Tokenization Protocol is a smart contract platform that allows issuers to create and issue token offerings in a regulatory compliant manner in a large number of jurisdictions around the globe. The protocol allows the integration of international regulations to enable compliant issuance of tokenized assets and cross-jurisdictional transfers of ownership. It also allows for issuer-specific parameters such as ownership concentration, holding periods, and voting. By issuing a permissioned ERC-20 token (STPT) on the Ethereum blockchain, Standard Tokenization Protocol ensures that: 1) regulatory and issuer-specific compliance requirements included in the smart contract are met at the token level, and 2) changes in the regulatory landscape can be captured and integrated. Standard Tokenization Protocol standard enables the tokenization of any type of asset in a globally compliant manner.
