AHash Time Lock Based on Double Encryption Algorithm

Abstract

With the rapid development of blockchain technology in recent years, many blockchain networks suitable for different types and scenarios have been born at home and abroad. Due to the characteristics of blockchain independence and network heterogeneity, there has been a scenario where data and assets cannot be exchanged and transferred between different blockchain networks, forming many value islands. Blockchain cross chain technology is an important technical means to realize the data circulation and value exchange between chains. As a mainstream cross chain technology, hash time lock (HTCL) technology originally came from Bitcoin's lightning network, which places transactions under the chain, greatly improving the speed of transactions. However, this algorithm has problems such as low security and transaction congestion in actual scenarios, This paper proposes a hash time lock based on dual encryption technology to ensure the security of the hash lock in the transmission process and effectively prevent the possibility of being intercepted and tampered with.
