A network of purpose-built blockchains are connected through the next-generation proof of stake blockchain protocol known as Polkadot, which enables them to work together at scale. A wide variety of practical use cases are made possible by Polkadot’s ability to send any sort of data between different types of blockchain.
Polkadot opens the door for new decentralised marketplaces to develop, giving better methods to access services through a variety of apps and providers by combining the greatest features from multiple blockchains.
Launched on May 26, 2020, its developers include Ethereum co-creator Gavin Wood. The principal research institution that looks after Polkadot’s open-source code is the nonprofit Web3 Foundation.
Its design offers several distinct advantages over existing and legacy networks, including heterogeneous sharding (to split large databases into smaller partitions), scalability, upgradeability, transparent governance and cross-chain composability.
The network can process more than 1,000 transactions per second, compared to about 7 for Bitcoin and 30 for Ethereum.
Polkadot will be able to scale even further in the future with a planned feature known as nested relay chains, which will increase the number of shards that can be added to the network.
Like all software, blockchains need upgrades in order to stay relevant. However, upgrading conventional blockchains requires forking the network, often taking months of work, and particularly contentious hard forks can break apart a community.
Polkadot revolutionizes this process, enabling blockchains to upgrade themselves without the need to fork the chain. These forkless upgrades are enacted through Polkadot’s transparent on-chain governance system.
With this feature, Polkadot enables projects to stay agile, adapting and evolving with the pace of technology.
The Polkadot token (DOT) serves two main functions within the Polkadot network: it’s a governance token, which allows holders to have a say in the future of the protocol, and it’s used for staking, which is the way the Polkadot network verifies transactions and issues new DOT.
