Distributed ledger technology has evolved well past its initial use case as the backbone of digital currency. Today, blockchain is being applied across diverse sectors to fix real-world inefficiencies.
Fundamentally, a distributed ledger is a distributed database that maintains a perpetually extending record of entries, called data records. Every entry contains a digital fingerprint of the previous block, forming an tamper-proof sequence.
Programmable contracts represent one of the most powerful use cases of distributed ledgers. Such automatically executing contracts autonomously enforce the terms of an contract when specific triggers are satisfied.
Financial services is one of the earliest adopters of Web3. Decentralized finance applications allow direct trading without traditional financial intermediaries.
Despite its promise, Web3 confronts meaningful hurdles. Processing capacity, energy consumption, and compliance complexity continue to be important considerations that should be solved before widespread use is achieved.
