This is a blockchain that allows several chains to work without problems, according to official data it is theoretically really interoperable allowing transfers between chains, among its characteristics is its high scalability to process transactions between chains, and easy integration and adaptation to new protocols and chains.
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 dispenses these concerns through the reconciliation of an assortment of exclusive advancements. Remarkably, it is even ready to convey data from private blockchains to public networks and the other way around.
The framework capacities in a novel way that joins a network of heterogeneous blockchains called parachains and parathreads. These chains associate with and are secured. There are additional examples where these chains interface with outer networks by means of scaffolds also. This plan gives it added adaptability.
It has important associations with other projects, such as ChainX, Polymat, Dock.
The most important thing is that it maintains the integrity of its respective chain, so there are no modifications to or centralized storage. Currently the networks are not integrated, this process is still under development. The team that is developing this project also has important partners. I think its biggest problem is that it should be listed in other exchanges that give credibility to the project such as binance or others that handle a better volume.
