A Framework for Full Decentralization in Blockchain Interoperability.

Area of Science:

• Computer Science
• Cryptography
• Distributed Systems

Background:

• The proliferation of diverse blockchains has led to significant interoperability challenges, hindering seamless data and asset exchange.
• Existing blockchains often lack standardized protocols, preventing direct communication and integration between disparate networks.
• The need for secure and decentralized solutions to bridge these isolated blockchain ecosystems is paramount for broader adoption.

Purpose of the Study:

• To present a novel framework enabling decentralized interoperability between distinct blockchain networks.
• To maintain the inherent decentralized nature of blockchains while facilitating cross-chain communication.
• To enhance the security and integrity of data transferred across different blockchain platforms.

Main Methods:

• Implementation of a decentralized framework for cross-chain communication.
• Utilization of data encryption and hash-based verification to ensure transfer integrity.
• Application of light client verification, based on Simplified Payment Verification (SPV), for transaction validation.
• Development and testing of a modified peer-to-peer network setup for the framework.

Main Results:

• The proposed framework successfully enables interoperability between blockchains while preserving decentralization.
• Data encryption and hash-based verification confirm the integrity and security of inter-blockchain data transfers.
• Light client verification ensures that only valid transactions are processed and appended to the destination blockchain.
• Comparative analysis of the peer-to-peer network setup against a client-server model indicates its computational feasibility.

Conclusions:

• The developed framework offers a robust and secure solution for achieving blockchain interoperability in a decentralized environment.
• The integration of encryption, hash-based verification, and light client verification addresses key security concerns in cross-chain transactions.
• The modified peer-to-peer network demonstrates a viable approach for scalable and efficient inter-blockchain communication.
