The field of blockchain research is moving towards enabling greater decentralization and interoperability between different blockchain networks. This is driven by the need to provide services traditionally offered by the internet in a decentralized manner, marking the emergence of the Internet of Blockchains. Recent work has focused on developing decentralized architectures for network discovery, high-performance decentralized storage protocols, and mechanisms for trustless data trading. Noteworthy papers in this area include:

• Enabling Blockchain Interoperability Through Network Discovery Services, which proposes a decentralized architecture for blockchain network discovery.
• Shelby: Decentralized Storage Designed to Serve, which introduces a high-performance decentralized storage protocol that achieves fast and reliable access to large volumes of data while preserving decentralization guarantees.
• Yotta: A Large-Scale Trustless Data Trading Scheme for Blockchain System, which proposes a complete batch data trading scheme for blockchain that features a data trading design leveraging innovative cryptographic workflow with IPFS and zk-SNARK.
• Enabling Bitcoin Smart Contracts on the Internet Computer, which presents an architecture that enables the execution of Turing-complete Bitcoin smart contracts on the Internet Computer, a blockchain platform for hosting and executing decentralized applications.
