Still, it's a massive development effort and merits a spot here. It's been developed by Intel's incubation group initially and opensourced in March 2016. |

Factom anchors itself in the Bitcoin and Ethereum blockchains, but operates its own data chains too. The anchoring part (and the start of the project) is based on the bitcoin "wire" level protocol library. Here, I am using the initial commit by Paul Snow (current CEO of Factom) as the start of the Factom project itself (the project was still called NotaryChain back then). This project could as well go into the "dismissed" tab, because it's not fitting the rules perfectly and doesn't have one public blockchain, but one could also argue that it merits the spot here. |

Polkadot is a "heterogenous multi-chain technology", but it's definitely built from scratch and has one central "relay" chain. |
