Enhancing Payment Channel Network Routing with Multiparty Computation
2025 7th Conference on Blockchain Research & Applications for Innovative Networks and Services (BRAINS)Payment Channel Networks (PCNs) offer a scalable solution for off-chain cryptocurrency transactions, but suffer from low success rates and security challenges. A key issue lies in the lack of visibility into channel balances during route discovery, which

Thor: A Virtual Payment Channel Network Construction Protocol over Cryptocurrencies
IEEE Conference on Computer CommunicationsPayment Channel Networks (PCNs) have been proposed as a second-layer solution to the scalability issue of blockchain-based cryptocurrencies, most developed systems still lack effective strategies for further scalability solutions. Virtual payment channel

Avoiding Deadlocks in Payment Channel Networks
2018Payment transaction channels are one of the main proposed approaches to scaling cryptocurrency payment systems. Recent work by Malavolta et al. [7] has shown that the privacy of the protocol may conflict with its concurrent nature and may lead to deadlocks.

Assessing Routing Algorithms for Payment Channel Networks
Distributed Ledger Technologies: Research and PracticePayment Channel Networks (PCNs) are a promising approach to overcome scalability issues of blockchains. To achieve efficient payments in PCNs, it is necessary to route transactions between a payer and a payee. Especially in large-scale PCNs, multi-hop routing becomes necessary, since transactions need to be relayed by nodes.

Post-Quantum Adaptor Signatures and Payment Channel Networks
2020Adaptor signatures, also known as scriptless scripts, have recently become an important tool in addressing the scalability and interoperability issues of blockchain applications such as cryptocurrencies. An adaptor signature extends a digital signature in a way that a complete signature reveals a secret based on a cryptographic condition.

AODV–Based Routing for Payment Channel Networks
2018Payment Channel Networks such as the Lightning Network (LN), Raiden or COMIT were created to tackle the scalability problems of their underlying blockchains, by moving from expensive and slow on-chain transactions to inexpensive and fast off-chain ones. However, those networks are unregulated and decentralised, comprise point-to-point channels that may
