Factom is a decentralized data storage platform that augments the storage and auditing capabilities of the Bitcoin blockchain. Factom provides an an additional data layer that allows users to store and audit data more efficiently and to overcome the storage limitations caused by small block sizes. It also allows organizations to leverage the benefits of blockchain, while providing a mechanism for auditing and ensuring relevant compliance. Factom offers an API that can be used to develop decentralized projects, and is designed to assist government agencies, businesses, and non-profits. The blockchain has a hybrid consensus mechanism, with elements of Proof-of-Existence (PoE), Proof-of-Process (PoP), and Proof-of-Audit (PoA).

The Lambda blockchain infrastructure will enable scalable data storage for DApps. Lambda Chain will also enable cross-chain data management. The network is currently powered by the Ethereum-based LAMB token.

Tierion is developing a blockchain solution for verifying data. Tierion's platform will be aimed for businesses and developers. "Proof" will allow businesses to prove the integrity and timestamp of data without depending on a trusted third-party. "Chainpoint" will enable developers to anchor data to the blockchain; giving them the ability to create a verifiable audit trail for data, and timestamp important documents.
Tierion's network is powered by the TNT token.
