DDK is a community platform that aims to create economic opportunities through the development of blockchain solutions. Since 2015, the DDK community claims to have contributed to a number of blockchain platforms.The DDK platform uses the Delegated Proof of Stake (DPoS) mechanism within its core. According to DDK, one of the advantages of a DPoS blockchain is that it depends on community members to participate in the maintenance and security of the platform so that each member’s participation provides benefit for all.
Akropolis is building a domain-specific financial protocol dedicated to the needs of the informal economy. It is designed to: - Enable anybody regardless of geography to quickly set up, operate and grow informal autonomous financial organisations (AFOs), e.g. digital co-ops, guilds, mutuals - Enable a previously impossible interoperable scalable network between them and external third parties, whereby value can be exchanged freely in a trust-minimised way (e.g. co-invest, lend/borrow, trade). - Reduce instances of fraud and misuse of funds
