For each transaction hash included in the final block
header, the node checks whether its corresponding
transaction content is available. If the corresponding
transaction was proposed by the shard to which the node
belongs, then the hash of the transaction data is compared
with the hash contained in the final block header.
If the transaction was proposed by another shard, the
transaction data is shared asynchronously across shards.
If the transaction was proposed by another shard, the transaction data is shared asynchronously across shards
A lot of critical information is hidden from this unclear sentence.How the transaction data shared asynchronously across shards withought compromising the overall security and how your preserve the eventual atomicity???
PS i would be grateful if i have the opportunity to further discuss with someone from your team privately in gitter chat some of my concerns thnx in advance.
