The Interplanetary File System (IPFS) is a decentralized network protocol for sharing hypermedia in a distributed file system. IPFS can be used to link blockchain transactions This effectively timestamps and secures the content, without having to put the data on the chain itself. Filecoin, an IPFS-based decentralized storage cloud, is closely related with the IPFS protocol, and provides the incentive system.

Alqo is developing an ecosystem of decentralized products and services that will be powered by the Alqo coin (XLQ). Their blockchain-based ecosystem enables instant and anonymous transactions. The XLQ coin is designed to be a multipurpose coin that will be used by all projects in the "Alqo Planetary System." Alqo is currently building Bitfineon (cryptocurrency exchange) and Payinx (payment solution for merchants). They plan on adding more projects (planets) to their ecosystem later. The Alqo network uses a modified Proof-of-Stake (PoS) consensus mechanism and an improved version of Zerocoin for encryption. The Alqo DAO (Decentralized Autonomous Organization) uses a Carbon Voting system to resolve governance issues.

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.
