Web3 Foundation: An organization that funds research and development teams. It is an organization that has provided funds for many projects until today. It is a very experienced system in smart contracts. Polkadot acts as a bridge between blockchains. Polkadot has 4 goals:
1- Managing transactions on the network
2- arranging operations
3- To establish connections between operations (bridge duty)
4- Finally, running these connected operations together.
Polkadot can process multiple transactions at the same time. And it completely eliminates any problems (Bottlenecks incidents) that may arise.
As a result: I think Polkadot, which also supports Ethereum users, will be one of the best systems of the future. I trust this system very much. Because the Web3 Foundation funding this system. Web3 Foundation never invests in bad systems. Polkadot has taken its place in the crypto world as the system of the future.
