This data is on the Ethereum main network.
It is preserved and secure for as long as Ethereum exists,
stored on a smart contract directly on the blockchain.
It is stored on a smart contract on-chain,
but is not secure or preserved until it is put on the
Ethereum main blockchain, or mainnet.
Thankfully, the project is fully funded to bring it to the Ethereum mainnet.
