Polkadot is a multi-blockchain technology that is designed to improve the compatibility of different blockchains. This is due to the fact that projects can communicate with each other (transfer arbitrary data, and not just tokens) and strengthen the overall security.
The goal of Polkadot is to change the structure of the Internet on Web3 to a completely new and decentralized network, where control will belong entirely to the users. And at the same time, make sure that all transactions take place in good faith and that the blockchains involved remain completely secure.
The Polkadot ecosystem also has its own token — DOT.
- A relay chain is the basic Polkadot chain that connects all the individual blockchains (parachaines) in the network and ensures the exchange of transactions between the chains. Guarantees consensus and security.
- Parachains (short for “parallelized chain”) are individual parallel blockchains that conduct transactions and transfer them to the source blockchain.
- Bridges (Bridge Chain) connect blockchains that do not use Polkadot control protocols (e.g., Ethereum, Bitcoin and Tezos).
A bridge between Free TON and Polkadot has been under development since October 2020.
