![]() Polkadot intends to allow any public or private blockchain to communicate with each other-it’s meant to be the “internet of blockchains.” Polkadot’s Native Token: DOT They don’t have much interaction between them. Thibault Perréard, head of finance for cross-chain staking hub Bifrost, says most of these Layer 1 systems are siloed. All the Layer 1 programmer has to do, then, is focus on optimizing their own project. They need to build the base layer before they can even start incentivizing hundreds of people to run their Layer 1 program on a computer, says Bill Birmingham, chief investment officer at Osprey Funds.Įxperts say Polkadot already has the base layer built. Layer 1 blockchains, like the Ethereum project Wood built along with co-founder Vitaly Dmitriyevich “Vitalik” Buterin and others, allow programmers to build decentralized applications (DApps), smart contracts, non-fungible tokens ( NFTs) and more.īut it’s hard for programmers to build a Layer 1 blockchain. Polkadot provides a built-in infrastructure upon which programmers can build their own blockchains with cross-chain interoperability. How Does Polkadot Work?ĭavid Lawant, director of research at Bitwise Asset Management, calls Polkadot a “heterogeneous multichain system.” That’s just a fancy way of saying that there are different blockchains operating on the Polkadot system.Īs noted above, a layer 0 blockchain functions as a foundational layer beneath layer 1 blockchains. The primary scaling issue that Wood wanted to address with Polkadot was the amount of computing power Ethereum required for its original proof-of-work validation system. With proof of stake, validators use tokens staked as collateral to determine the next block in the chain. In proof of work, blockchain miners solve cryptographic puzzles to add the next block to the chain for mining rewards. Proof-of-stake validation was proposed in contrast to earlier blockchains, such as Bitcoin (BTC) or Litecoin (LTC). Noticing issues with Ethereum’s ability to grow and scale, Wood attempted to solve this problem with a new blockchain based on a proof-of-stake validation system. When Wood first wrote the Polkadot whitepaper, he argued that crypto needed a new system allowing interactions between different blockchain networks. It calls itself a Layer 0 blockchain, whereas Ethereum and similar blockchains like Solana (SOL) and Cardano (ADA) are called Layer 1 blockchains. ![]() Polkadot operates at a deeper level than a blockchain like Ethereum-think of it as providing a foundation on which others crypto projects can build. The platform is now run by the Web3 Foundation (W3F), and developed by Parity Technologies, both co-founded by Wood. Launched in May 2020, Polkadot is the brainchild of Ethereum (ETH) co-founder Gavin Wood. Polkadot is envisioned as an improved version of Ethereum.
