“…Peter Robinson [ 20 ] analyzes how each protocol achieves cross-chain consensus, what trust assumptions are made, their ability to operate successfully in the context of permissionless and permissioned blockchains, and whether the protocols provide atomic updates across blockchains. Lydia Negka [ 21 ] et al propose a state channel design that is optimal for applications where the state includes a large set of elements by running an RSA accumulator on a compact state structure. This state channel design is presented by analyzing all the state channel operations and how these operations are modified, and finally discusses the security of the design, while analyzing a practical usage scenario on the design of an on-chain asset (e.g., NFTs) exchange application on this basis.…”

Blockchain cross-chaining is about interconnectivity and interoperability between chains and involves both physical to virtual digital aspects and cross-chaining between digital networks. During the process, the liquidity transfer of information or assets can increase the use of items with other chains, so it is worth noting that the enhancement of cross-chain liquidity is of great practical importance to cross-chain technology. In this model, Layerzero is used as the primary secure cross-chain facility to build a full-chain identity by unifying NFT-distributed autonomous cross-chain identity IDs; applying super-contract pairs to enhance cross-chain liquidity; and initiating a dynamic transaction node creditworthiness model to increase the security of the cross-chain model and its risk management. Finally, by verifying three important property metrics timeliness is improved by at least 18%, robustness is increased by at least 50.9%, and radius of convergence is reduced by at least 25%. It is verified that the liquidity cross-chain model can eliminate the authentication transition between hierarchies while saving the cross-chain time cost, as a way to truly realize the liquid interoperability between multiple chains of blockchain.

“…These channels offer a lightweight solution for scaling layer two transactions by conducting offchain transactions between parties. Payment channels evolution is elevated by state replacement techniques, which assume rational behaviour and adherence to agreed-upon obligations by channel participants [52]. Two smart contracts are utilized in state channels: one for the state channel and the other for the application execution.…”

“…The dispute handler verifies evidence during a waiting period and commits the state with the highest round number. After finalizing the state, participants can submit new inputs for the subsequent round [36], [52]. State Replacement Techniques (SRT) represent controlling techniques to ensure the channel's evolution by replacing the old state with a new state.…”

“…These disputes can arise when a party attempts to deceive others by submitting an outdated transaction state to gain unauthorized access to previously acquired funds or when a party becomes unresponsive and unexpectedly disconnects from the network. Synchronous communication is employed on the layer one blockchain to handle such disputes, allowing parties a specific response timeframe [52], [96]. However, synchronous communication with the onchain layer poses challenges.…”

Blockchain technology era is triggered due to current advancement in the decentralized paradigms via facilitating secure collaboration among untrusted entities consequently superseding the necessity for the trusted third parties’ existence. Notwithstanding its potential, blockchain scalability faces severe limitations such as low throughput, high fees, and confirmation time latency. Several scaling solutions have been proposed, including layer one solutions that substantially require fundamentally amending blockchain underlying infrastructure resulted in further scalability complications. Layer two solutions, specifically Lightning Network, is a successful cryptographic layer built atop of the Bitcoin blockchain that aims to alleviate these implications by deporting transaction processing outside blockchain while ensuring security and consensus inherited from blockchain without compromising its infrastructure. Payment channels form the core of the lightning network, facilitating fast and secure transactions between participants. However, the network encounters substantial obstacles associated with transaction amounts that exceed the current channel capacity, leading to payment failures and limiting its effectiveness. Payment Channel Networks (PCN) have been risen as an evolved replacement that solves payment channel’s issues, seeking to enhance transaction throughput and reduce confirmation delays by solving limited capacities shortages. This paper thoroughly examines PCN efficiency impacting factors that hinder its current adoption growth and avoiding its widespread employment. Additionally, existing solutions are reviewed and categorized based on the PCN building architecture. The research concludes by outlining potential research avenues and future directions to improve the efficiency and practicality of the Lightning Network PCN. This research contribution aids the advent of blockchain layer two technology and participates in its integration into real-world applications.
