Abacus Protocol

Abacus is an identity and compliance protocol for permissioned tokens and a permissionless protocol for services that facilitate the issuance, administration, and settlement of tokenized financial instruments on the blockchain.

Their stated mission is 'to build the open financial infrastructure of the future and pave the way for the total automation of financial instruments.'

The Abacus Protocol includes a registry of on-chain compliance standards: smart contracts to provide automated regulatory compliance for smart financial tokens.

They work with Morrison & Foerster to launch the protocol with the following two compliance standards:

• The protocol allows these regulatory guidelines to be automatically enforced on every transaction and facilitates 'compliant' token offerings.
• To facilitate these needs, the protocol allows off-chain service providers to write data onto the blockchain that other smart contracts or users in the ecosystem can use, adding to the vault of 'trusted' information on the protocol.
