Blockchain Scalability and Security: Communications Among Fast-Changing Committees Made Simple. (arXiv:2212.11700v1 [cs.CR])

For permissionless blockchains, scalability is paramount. While current
technologies still fail to address this problem fully, many research works
propose sharding or other techniques that extensively adopt parallel processing
of transactions. In these approaches, a potentially large number of committees
of nodes independently perform consensus and process new transactions. Hence,
in addition to regular intra-committee communication, (1) new transactions have
to be delivered to the right committee, (2) committees need to communicate to
process inter-shard transactions or (3) to exchange …
