Most blockchain-based cryptocurrencies suffer from a heavily limited transaction throughput, which is barrier to their growing adoption. Payment channel networks (PCNs) are one of the promising solutions this problem. PCNs reduce on-chain load transactions and increase throughput by processing many payments off-chain. In fact, any two users connected via path payment channels (i.e., joint addresses between end-points) can perform payments, underlying blockchain used only when there dispute users. Unfortunately, in be conducted securely along path, prevents design interesting applications. Moreover, most widely implementation, Lightning Network Bitcoin, suffers collateral lock time linear length, it affected security issues, relies on specific scripting features called Hash Timelock Contracts that hinders applicability protocol other blockchains.
