Public Blockchain

A public blockchain is a decentralized, distributed ledger accessible to anyone on the internet without permission or restriction. These blockchains, like Bitcoin and Ethereum, allow participants to read, write, and validate transactions, ensuring transparency and trust. Public blockchains operate under consensus mechanisms such as Proof of Work (PoW) or Proof of Stake (PoS), where participants (miners or validators) maintain the network's integrity by verifying new transactions. Since they are open-source, public blockchains enable decentralized applications (dApps) and smart contracts that do not rely on central authorities, promoting greater security and autonomy. Public blockchains are pivotal in sectors like finance, supply chain, and digital identity, as they provide transparency, data immutability, and trustless transactions, empowering users globally.
