Polkadot is an open-source, sharded protocol that carries in its batch two types of blockchains. One is a relay chain playing the role of a main network where permanent transactions take place and the other is parachains, also known as user-created networks. Owing to its versatile nature, the latter can be customized for an unlimited number of uses and integrated into the main blockchain. This integration allows parachain transactions to enjoy the same security as the main chain does. To ensure that transactions on Polkadot are dealt with an optimal level of security and accuracy, it is designated as having certain computing resources to deliver performance in the main chain. It suffices to say that in this resurgence, Polkadot manages to resolve some remaining problems, meaning that it shall not risk disclosing user data to the public network and at the same time processes a greater number of transactions.
