Web 3.0 is a project that aims to realize a decentralized web world without centralization, and a blockchain for this purpose.

It is a network protocol that allows arbitrary data as well as tokens to be transferred between blockchains.

The currency unit for tokens used in Polka Dot is DOT.

The main chain, Relay Chain, is connected to multiple blockchains called Parachain, which process each transaction in parallel to increase processing speed and solve the scalability problem.

A blockchain development tool called Substrate is available to the public, allowing anyone to develop a blockchain compatible with Polka Dot.

Polkadot holders are given governance rights to determine fees within the network, add and remove blockchains, and update the protocol.

In order to become a member of the Polkadot network, a DOT token must be staked, which makes it difficult for participants to engage in fraudulent activities.

It is said to have the potential to solve the problem of fat protocol, which is a problem in the blockchain industry structure.

It can be purchased on Binance, etc.
