A computer-implemented method for blockchain data storage includes sending a marker message from a first blockchain node in a first shard of a blockchain network to a second blockchain node in a phosphor of the blockchain network; receiving a marker block from the second blockchain node, wherein the marker block is associated with the phosphor and includes the marker message; creating a first block associated with the first shard that includes a block associated with the phosphor that immediately precedes the marker block; creating a second block associated with the first shard that includes the marker block; generating, during creation of the second block associated with the first shard, a snapshot of state information corresponding to a newest block associated with the first shard; and storing the snapshot of the state information.
