Skycoin began as an ambitious infrastructure project aimed at replacing the Proof-of-Work (PoW) and Proof-of-Stake (PoS) consensus algorithms that dominate current blockchain platforms. It has since evolved into a project focused on creating a decentralized mesh-Internet and a platform for other blockchain-based projects. Skycoin is developing an ecosystem with a variety of goals, including: the elimination of mining rewards, development of energy-efficient custom hardware, advancing security and privacy, and achieving transaction speeds that rival current digital payment systems. The ecosystem consists of the native SKY coin, Skywire (decentralized mesh-Internet), Skyminer (hardware and access point for Skywire), Skyledger (decentralized open blockchain network), and a suite of DApps. The consensus algorithm is called Obelisk. The network's nodes agree based on a Web-of-Trust consensus. The ability to influence transaction verification is distributed over the network creating a web of trust. To eliminate mining completely each node on the network connects to a list of nodes that it sees as trustworthy.

Harmony is developing an open consensus blockchain platform. Harmony's sharding-based consensus mechanism is designed to scale as the number of nodes increases in the network. Harmony aims to tackle issues related to scalability by optimizing across multiple layers in a way that will enable parallel transaction processing with reduced latency. Harmony is currently powered by the ONE token, which is built on the Binance blockchain.

CyberMiles is developing a decentralized ecosystem for e-commerce. Their blockchain platform will provide users a library of e-commerce focused smart contracts to develop DApps and will facilitate decentralized settlements between parties.
The Cybermiles blockchain will be optimized specifically for e-commerce exchanges and will maintain records of users' identities, credit histories, and reputation scores. Users will be able to enter into smart business contracts without human intervention.
The CMT token will power the CyberMiles e-commerce network
