Web 3.0, the next generation of the internet, has been envisioned by proponents to run on a fully-decentralized blockchain to create a user-friendly web wherein a user’s identity and data are their own.
Creating a multichain future
Polkadot was created with just that goal in mind—with the belief that no single blockchain can support the entire Web 3.0 economy and that multichains are the future of such an unconnected ecosystem.
But such an implementation requires blockchains to interact, exchange data (almost speak) to one other). This is where “bridges” come in, a technology that Polkadot looks to implement.
The project realizes that while its underlying infrastructure allows developers with the necessary tools required for scalability and high throughput, there are existing networks with strong communities outside of the Polkadot ecosystem which make the use of cross-network bridges necessary.
