Decentralized systems has grown well past its original use case as the foundation of digital currency. Now, decentralized technology is being applied across many industries to fix practical problems.
Fundamentally, a decentralized network is a decentralized ledger that maintains a ever-expanding sequence of entries, called blocks. Each record holds a unique identifier of the prior record, creating an permanent history.
Programmable contracts represent one of the most significant use cases of distributed ledgers. These programmable contracts automatically execute the conditions of an deal when predefined requirements are satisfied.
Banking and finance has been one of the first adopters of distributed ledgers. Blockchain-based finance applications allow trustless lending without traditional banks.
Despite its promise, blockchain confronts significant challenges. Processing capacity, energy consumption, and legal ambiguity persist as key considerations that should be resolved before mainstream adoption is achieved.
