Polkadot (DOT) is a next-generation protocol platform designed to securely connect and interact between chains (Parachains). The Polkadot platform was established in May 2020 by Gavin Wood - one of the co-founders of Ethereum. The purpose of this protocol is to increase the ability to interact between platforms, blockchains with each other safely and quickly. Users connected to Polkadot can freely transfer data or any assets without the need to withdraw to an external wallet.
In addition to the main goal of connecting blockchains to each other, Polkadot also solves issues such as increasing transaction processing speed, providing network expansion capabilities for platforms, and increasing network reliability,... The DOT cryptocurrency is a native token on the platform now used as a means to vote for network governance and pay transaction fees...
Overall, Polkadot is a useful solution to solve the current problem of having too many separate platforms that make it difficult for users to interact between them. With this potential for development, the demand for DOT transactions is expected to increase day by day, however, there are still risks that investors should carefully research before participating.
