Prophet: Conflict-Free Sharding Blockchain via Byzantine-Tolerant Deterministic Ordering. (arXiv:2304.08595v1 [cs.CR])
cs.CR updates on arXiv.org arxiv.org
Sharding scales throughput by splitting blockchain nodes into parallel
groups. However, different shards' independent and random scheduling for
cross-shard transactions results in numerous conflicts and aborts, since
cross-shard transactions from different shards may access the same account. A
deterministic ordering can eliminate conflicts by determining a global order
for transactions before processing, as proved in the database field.
Unfortunately, due to the intertwining of the Byzantine environment and
information isolation among shards, there is no trusted party able to
predetermine …
