Abstract
Disclosed techniques relate to a method of securing a distributed ledger system, comprising: receiving, from a user application executed on an electronic user device and at a shared security platform executed on a backend, a request for a private key, the private key capable of accessing an account of a distributed ledger network; generating and storing a first shard of the private key on a smart card using the protocol; generating and storing a second shard of the private key on at least one institution backend using a protocol; receiving, from a merchant point of sale system, a request for a transaction associated with the account and the first shard; retrieving, from the at least one institution backend, the second shard; and generating the private key from partial signatures of the first shard and the second shard, and upon generating the complete signature, executing the transaction.
