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.

Klaytn Coin is the native currency of the Klaytn blockchain. It was developed by the South Korean internet giant, Kakao and is operated by its subsidiary Ground X. Klaytn Coin is designed to power an enterprise-grade, service-centric platform that brings a user-friendly blockchain experience to its users. It has a hybrid architecture that combines elements of public and private blockchains. Klaytn uses an optimized version of the Istanbul Byzantine Fault Tolerant consensus algorithm. There are three types of nodes, CN (Consensus Node), PN (Proxy Node) and EN (Endpoint Node). CNs are managed by CCOs (Core Cell Operators) and are in charge of block generation. These blocks are verified by all nodes in the network.
It has partnerships with multiple prominent companies, including Binance, which serves on their governance council, and several large South Korean banks and technology companies. The company also plans to integrate with OpenSea's NFT marketplace to allow Klaytn-powered NFTs to be sold more easily.

TrueChain is developing a secure and scalable blockchain platform with a strong developer community. TrueChain hopes to improve upon current platforms with a hybrid consensus protocol called Minerva. This hybrid model will combine a consensus mechanism based on Practical Byzantine Fault Tolerance (pBFT) with a FruitChain-based Proof-of-Work protocol. Fruitchain is designed to minimize the incentives of mining pools by decreasing the variance of mining rewards; making the network more decentralized.
TrueChain's architecture also hopes to improve transaction times and reduce fees, by including a sharding mechanism that is locked to Gas fees. The first use cases for their platform will be digital advertising solutions.
The company is backed by several large Chinese blockchain companies, including ZB.com; one of the largest cryptocurrency exchanges. digital advertising industry
