Web3 is a model of the internet where users hold their own digital assets and identity through blockchain-based applications. Instead of logging into central platforms, people connect wallets to apps built on smart contracts and tokens.
A blockchain developer builds applications, smart contracts or core infrastructure on blockchain networks. The work ranges from protocol code to the services that connect users to chains, and hiring one makes sense when part of your product must run on a shared ledger.
A decentralized autonomous organization (DAO) is a group coordinated through smart contracts rather than a management hierarchy. Members propose and vote on decisions such as spending or protocol upgrades.
A Web3 wallet is an app or device that holds the keys to a user's blockchain accounts and signs transactions. It lets people hold assets and connect to decentralised applications under their own control.
A blockchain is a shared, append-only digital ledger that many computers keep in sync without a central owner. Records are grouped into blocks linked by cryptography, which makes past entries very hard to alter.
