With the rise in the use of blockchain-based products and services, the enterprise demand for reliable performance, versatility, and blockchain interoperability solutions has increased as well. One of the most prominent bottlenecks that are hindering the mainstream adoption of distributed ledger technology (DLT) solutions is their interoperability. However, the rapid pace of development of blockchain interoperability solutions comes as a ray of hope that seeks to close the informational gap between different isolated blockchains.
Tackling the Blockchain Interoperability Issue
At a broad level, blockchain can be viewed as both – a distributed and an independent ledger. An interoperability or a cross-chain solution is of particular significance in the DLT ecosystem as it would function as a catalyst that transforms an isolated blockchain into an interconnected one. It won’t be an exaggeration to state that robust blockchain cross-chain solutions hold the potential to increase blockchain’s utility exponentially and play a key role in fostering the maturity of the DLT ecosystem.
As a decentralized open-source blockchain project, aelf has successfully developed a cross-chain transfer protocol based on its multi-level “main chain – multiple side chains” structure. The cross-chain protocol developed by aelf specifically focuses on ease of use, scalability, and security. Per sources close to the matter, the newly developed protocol processes smooth cross-chain transfers between independent blockchain systems. What’s more, it also supports applications that demand the transfer of assets between different blockchain systems.
aelf’s protocol provides a standard solution for cross-chain transfers and a unified specification for cross-chain asset transfer between DLT systems. Additionally, it also offers a standardized interface and data structure that enables decentralized cross-chain asset transfer services thereby functioning as a common solution for developers.
The protocol’s goal is twofold.
First, it seeks to eliminate the issues pertaining to lack of data connection and low interoperability resulting from the incompatibility of different blockchain protocols. Second, the protocol wants to solve the notorious problem of low efficiency/high cost of cross-chain asset transfers.
The Application of the Protocol
The cross-chain protocol is applicable to the following three scenarios:
1. Cross-chain asset transfers between blockchain systems.
2. Cross-chain asset exchange between blockchain systems.
3. Finish existence proof between blockchain systems.
The need for the establishment of unified data format standards is the need of the hour to facilitate seamless interaction among different blockchain systems using different governance protocols and data structures. These data standards must be compatible with various blockchain protocols so they enable cross-chain transfers and, subsequently, help establish common assets cross-chain standards.
In essence, there’s an immediate need to define the standard structure of asset cross-chain transfer data.
At the same time, it’s also worth noting that the cross-chain asset transfer process is based on cross-chain Existence Proof, which, in turn, is dependent on the Merkle Proof mechanism. This necessitates the need for a unified verification method to foster cross-chain verification across different blockchain systems which can only be achieved by defining the standard method of cross-chain Existence Proof.
aelf Committed to Establishing a Unified Cross-Chain Protocol
There’s no doubt that a future where blockchain solutions and services are the norms, there will be no dearth of cross-chain and interoperability solutions. The blockchain-enabled world of the future will inarguably comprise of chains that are able to interact with one another without any hiccup.
As the vast majority of chains today are heterogeneous in nature, the free flow of information from one chain to another is central to creating value and utility around these networks. This can only be achieved by establishing a unified cross-chain protocol that stretches the corners of today’s blockchain ecosystem.
Concluding, aelf’s cross-chain transfer protocol is a testimony to its commitment to foster a tomorrow that is not only decentralized and secure but also communicates freely. Through its protocol, aelf aims to enable seamless cross-chain interaction between chains. The exponential growth of the aelf ecosystem will directly lead to increased use-cases and value of its cross-chain protocol.
