Methods, systems, and techniques for generating a new blockchain involve storing, in an existing blockchain, a genesis block of the new blockchain; and hosting the new blockchain using the genesis block of the new blockchain as a first block of the new blockchain. The storing may be done before the hosting, such as when the existing blockchain generates the genesis block of the new blockchain itself and subsequently causes the new blockchain to be hosted. Alternatively, the hosting may be done before the storing, such as when a node foreign to the existing blockchain generates the genesis block of the new blockchain and hosts the new blockchain, and the genesis block of the new blockchain is subsequently introduced to and stored in the existing blockchain.
