Blockchain technology has matured significantly beyond its original use case as the foundation of digital currency. Today, decentralized technology is being deployed across many industries to address genuine problems.
In essence, a blockchain is a shared record system that maintains a ever-expanding sequence of entries, known as blocks. Each block contains a cryptographic hash of the prior record, establishing an tamper-proof sequence.
Self-executing contracts constitute one of the most powerful applications of distributed ledgers. These programmable contracts autonomously execute the conditions of an deal when predetermined triggers are satisfied.
Financial services has been one of the first embracers of distributed ledgers. DeFi protocols are enabling peer-to-peer borrowing bypassing centralized banks.
While the potential is significant, the technology confronts meaningful limitations. Scalability, environmental impact, and compliance complexity remain significant issues that need to be addressed for broad adoption to happen.
