Payment Trees: Low Collateral Payments for Payment Channel Networks
2021The security of blockchain based decentralized ledgers relies on consensus protocols executed between mutually distrustful parties. Such protocols incur delays which severely limit the throughput of such ledgers. Payment and state channels enable execution of offchain protocols that allow interaction between parties without involving the consensus ...

Lightweight Virtual Payment Channels
2020Blockchain systems have severe scalability limitations e.g., long confirmation delays. Layer-2 protocols are designed to address such limitations. The most prominent class of such protocols are payment channel networks e.g., the Lightning Network for Bitcoin where pairs of participants create channels that can be concatenated into networks. These allow

Utility-Aware Payment Channel Network Rebalance
Proceedings of the VLDB Endowment, 2023The payment channel network (PCN) is a promising solution to increase the throughput of blockchains. However, unidirectional transactions can deplete a user's deposits in a payment channel (PC), reducing the success ratio of transactions (SRoT). To address this depletion issue, rebalance protocols are used to shift tokens from well-deposited PCs to ...

Payment Channel Attack Vectors
2020Criminals are predators, seeking any opportunities to exploit bad practices or poorly configured, or managed, systems. Increasingly, consumers are seeking to use more convenient, efficient, and quicker ways to purchase goods or services. In response to this demand, businesses are turning to new technologies to meet customer expectations.

Card Payment Protocol for Cryptocurrencies with Payment Channel Network
Distributed Ledger Technologies: Research and PracticeCryptocurrency, despite the upsurge as a speculative investment, is still a long way from being people’s money. The extreme technicality poses a significant barrier for the general public to adopt it as a medium of exchange. Therefore, simplifying the payment process is a predominant necessity; for example, facilitation in adopting conventional payment

Super Payment Channel for Decentralized Cryptocurrencies
2019 IEEE Conference on Dependable and Secure Computing (DSC), 2019Payment channel with penalizing double-spending has been widely applied in cryptocurrencies for achieving fast payment. However, current payment channel solutions suffer at least one of the following problems: 1) large overheads and communication costs are incurred to thwart double-spending; 2) payees must be defined before building payment channels; 3)

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.

Payment Channel Network for Scriptless Blockchains
2023Payment channels help make blockchains more scalable, but creating them for scriptless blockchains like Monero is challenging. This study introduces AuxChannel, the first bi-directional payment channel protocol for scriptless blockchains without a limited lifetime.
