SyncPCN/PSyncPCN: Payment Channel Networks without Blockchain Synchrony. (arXiv:2207.11615v2 [cs.CR] UPDATED)

Payment channel networks (PCNs) enhance the scalability of blockchains by
allowing parties to conduct transactions off-chain, i.e, without broadcasting
every transaction to all blockchain participants. To conduct transactions, a
sender and a receiver can either establish a direct payment channel with a
funding blockchain transaction or leverage existing channels in a multi-hop
payment. The security of PCNs usually relies on the synchrony of the underlying
blockchain, i.e., evidence of misbehavior needs to be published on the
blockchain within a time …
