It is implementing protocols that enable communication and collaboration between different blockchain networks. Examples include Polkadot’s Substrate framework, Cosmos’ Inter-Blockchain Communication (IBC) protocol, and Ethereum’s Interoperability Protocol (EIP) standards.

  • Atomic swaps

Atomic swaps allow for the peer-to-peer exchange of cryptocurrency in business without the need for intermediaries. This blockchain interoperability medium ensures that either both parties successfully complete the transaction or neither does, preventing the risk of one-party defaulting.

  • Sidechains

Sidechains are independent blockchains connected to a parent blockchain (mainchain) through two-way pegging. They enable the transfer of assets from the mainchain to the sidechain and vice versa to facilitate trusted interoperable blockchain and automate security operations.

  • Token standards and wrappers

This involves creating token standards or wrapping existing tokens to make them compatible across multiple blockchains. Examples include Wrapped Bitcoin (WBTC) on Ethereum, which represents Bitcoin on the Ethereum blockchain, and ERC-20 tokens, widely supported across various Ethereum-based projects.

  • Interoperability middleware

Middleware architecture offers intermediaries between different blockchains, translating data and facilitating communication between them. These blockchain interoperability solutions often include APIs, SDKs, and middleware platforms designed to simplify cross-chain interactions for developers.

Overcoming the formidable hurdles of interoperability emerges as a pivotal endeavor, essential for unlocking the full potential of distributed ledger technologies.
