Polkadot is a revolutionary blockchain infrastructure designed to enable the next generation of the web where users control their own data and identity. It creates this infrastructure by providing a way to connect different, independent blockchains together in a single network, allowing them to interoperate, exchange data, and process transactions with the benefit of shared security provided by the Polkadot Relay Chain. It also allows interaction with non-blockchain systems and established blockchains such as Bitcoin and Ethereum.
Polkadot is a project of Web3 Foundation.
Before being integrated into Polkadot, the technology can be tested on the experimental platform Kusama, which has been built with (almost) the same code.
DOT - the native Polkadot tokens - serve several functions. They:
give holders a role in controlling the governance of the platform
are staked for operating the network
can be bonded for a parachains
can be used to pay fees within the network
Polkadot is the brainchild of Gavin Wood, co-founder and former CTO of Ethereum.
Cryptocurrency mining is the process in which transactions between users are verified and added to the blockchain public ledger. The process of mining is also responsible for introducing new coins into the existing circulating supply and is one of the key elements that allow cryptocurrencies to work as a peer-to-peer decentralized network, without the need for a third party central authority.
Cryptocurrencies Use Decentralized, Distributed Systems
How does it work?
A miner is a node/device in the network that collects transactions and organizes them into blocks. Whenever transactions are made, all network nodes receive them and verify their validity. Then, miner nodes gather these transactions from the memory pool and begin assembling them into a block (candidate block).
