Abstract: A method of performing a blockchain transaction includes partitioning a private key of an account into a first part, a second part, and a third part, using a processor. The method further includes delivering the first part to a user of the account via a network. The method further includes storing the second part on a first server in association with information about the end-user. The method further includes receiving the first part from the user via the network. The method further includes reconstructing the private key of the account using the first part and the second part. The method further includes performing the blockchain transaction using the account and the reconstructed private key.
