Holo is a decentralized hosting provider that is built on top of Holochain. DApps can be set up and deployed with Holo hosting, as a decentralized alternative to Amazon Web Services, or other centralized hosting solutions.
Holochain is a protocol for creating decentralized Apps and is different from blockchain protocols in several ways. The main difference being that Holochain takes an agent-centric approach to their consensus mechanism, and has a different approach to validating value transfers.
The HOT token is used for paying for hosting services on Holo, and users can be paid for offering their computing resources.

Aeternity is a smart contract driven blockchain platform that aims to integrate real world data and improve the overall performance of smart contracts. Aeternity has a hybrid consensus algorithm that combines PoW for verifying transactions, and PoS for governance purposes. The platform is based on a system of state channels that allow users to interact privately with each other and record this information off-chain.

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.
