Abstract: Transaction handling computing elements comprise a network core that processes transaction requests into a blockchain, wherein a data block is a collection of transactions, and wherein an Unspent Transaction Output (UTXO) supporting the blockchain is an output from a finalized transaction. The elements interoperate with a transaction signing mechanism that associates a set of addresses on the blockchain with a delegate address, the delegate address having a set of signing public keys corresponding to one or more signing private keys used to sign UTXOs. In association with a new transaction being processed by the set of transaction handling components, a signing public key for an associated UXTO is located by following an address chain that includes an address in the set of addresses together with the delegate address. The signing public key is retrieved from a location associated with the delegate address and then used to sign (unlock) the associated UXTO.
