Another little-known fact about Web3 is the crucial importance of interoperability between different blockchains. This interoperability allows distinct blockchain networks to communicate, exchange information, assets, and services seamlessly, which is often a major challenge. Currently, many blockchains operate in silos, limiting the fluidity of Web3.
What is innovative is that there are already modular infrastructures and cross-chain bridges, like Polkadot or Cosmos, that aim to create a connected ecosystem. However, these bridges can be vulnerable to attacks, which drives the need for more secure solutions based on application standards and shared protocol layers for a truly interoperable Web3. This opens the door to uses such as the ability to use NFTs from one blockchain in applications of another blockchain, which is still not widely visible to the general public.
