A method of building a first distributed ledger based on synchronization with a proxy distributed ledger comprising a genesis block of a second distributed ledger and a contiguous plurality of last blocks of the second distributed ledger. The method comprises initializing a first distributed ledger by creating a first genesis block comprising executable instructions that implement a smart contract; initializing the proxy distributed ledger as a combination of the blocks read from the second distributed ledger; and building the first distributed ledger by creating blocks and adding the blocks to the first distributed ledger, wherein each block comprises a content field created at least in part based on processing one of the blocks of the proxy distributed ledger in time synchronization based on executing the executable instructions stored in the first genesis block.
