BOScoin is a South Korean company that is developing a self-evolving cryptocurrency platform for trust contracts. It uses an embedded decision-making system called Congress Network and has a Proof-of-Stake (PoS) consensus mechanism. BOScoin is working to construct an algorithm for smart contracts that will ensure binary responses. BOScoin tries to solve this problem of undecidability of smart contracts by using a domain-specific language understandable by the average user. It also tries to mathematically demonstrate the decidability of its smart contracts’ implementation. To do this, they've introduced the concept of Trust Contracts; which are securely executable contracts based on a technology called Owlchain.

High Performance Blockchain (HPB) is a Chinese company that is developing an improved blockchain infrastructure. Their goal is to dramatically improve the speed of transactions and throughput of existing blockchain systems. HPB has been called the EOS of China.
Similar to EOS, HPB uses a delegated Proof of Stake (DPoS) consensus algorithm that will enable parallel processing. It will also aid in improving the performance of their blockchain, and they hope that it will enable the creation of an ecosystem for the creation of decentralized applications.
HPB's platform is based on hardware accelerator chip drivers. The accelerator chips can be customized and will aid in the performance of the blockchain. HPB has the ambitious goal of enabling 1 million transactions per second.
The company's founders are well connected in the blockchain and payment sector in China. NEO is one of the chief investors in the company, and they also works with Union Pay; which is an influential payment network that connects banks in China.

RSK is an open source smart contract platform that is secured by the Bitcoin network. RSK is designed to add value and increase the functionality of the Bitcoin ecosystem by providing smart contracts that are compatible with the network's code and can be written in Solidity. RSK smart contracts are powered by the SmartBitcoin (RBTC) which is linked to Bitcoin. (1 RBTC=1 BTC)
RSK developed the RIF Token which is intended to enable users to access a range of DApps within their ecosystem. In September 2019, RSK purchased the Spanish social media platform Taringa with the goal of using the RIF token as an incentive to encourage users to share content.
