Claim 15:
16. A method comprising: receiving, by a full node from a client device, a query for a random sampling of block headers on a blockchain, the query including a random number, partitioning, by the full node, the blockchain into a plurality of blockchain partitions including a last partition, the last partition including a latest block header; randomly sampling of block headers from the block headers in the last partition equal to the random number to form the random sampling of block headers; determining, by the full node, a plurality of Merkle mountain range proofs associated with the random sampling of block headers; and transmitting, by the full node, the random sampling of block headers and the plurality of Merkle mountain range proofs to the client device, wherein the client device verifies the random sampling of block headers and the plurality of Merkle mountain range proofs.
