Decentralized systems has evolved significantly beyond its initial application as the base layer of Bitcoin. At this stage, distributed ledger is being applied across many fields to fix practical inefficiencies.
At its core, a decentralized network is a distributed database that records a ever-expanding record of records, called block entries. Each record includes a cryptographic hash of the previous block, establishing an tamper-proof history.
Programmable contracts constitute one of the most powerful use cases of distributed ledgers. These self-executing protocols autonomously execute the rules of an agreement when specific requirements are satisfied.
Financial services remains one of the most active adopters of blockchain technology. Decentralized finance platforms allow direct trading eliminating the need for traditional financial intermediaries.
While the potential is significant, blockchain faces significant limitations. Transaction throughput, environmental impact, and regulatory uncertainty remain important issues that must be solved before widespread adoption to happen.
