Overview of Blockchain Technology and Its Applications
This article explains the fundamental concepts of blockchain—including distributed storage, peer‑to‑peer transmission, consensus mechanisms and cryptography—illustrates its advantages such as cost reduction and transparency, compares it with cloud computing, and discusses its impact across industries while noting upcoming events.
The official definition of blockchain is a new application model that combines distributed data storage, peer‑to‑peer transmission, consensus mechanisms, and cryptographic algorithms.
Blockchain technology represents a way for everyone to participate in bookkeeping; behind every system there is a database that can be seen as a large ledger where each participant records their own transactions.
Because there is no centralized intermediary, all operations run automatically according to pre‑defined programs, dramatically lowering costs and increasing efficiency. Since everyone shares the same ledger, the recording process is publicly transparent.
Blockchain is the underlying technology of Bitcoin; Bitcoin has operated for many years without any central authority and without major issues, which led people to abstract its core technology and call it blockchain or distributed ledger technology.
A report by Spain’s largest bank, Santander, estimates that if all banks worldwide adopted blockchain technology around 2020, they could collectively save about US$20 billion per year, highlighting the massive transformation potential for traditional finance.
Cloud computing is usually defined as providing dynamic, scalable, often virtualized resources over the Internet, typically operated by a centralized provider. In contrast, a blockchain network lacks a specific central institution, making it closer to the definition of a distributed computing system.
Blockchain technology has evolved from the initial digital currency stage through three development phases to the current decentralized application 3.0 stage, permeating various industries. Is blockchain a universal cure or a flawless solution? Could it become the next disruptive core technology after the steam engine, electricity, and the Internet?
On January 16, 360 will hold a Shared Cloud Plan and Blockchain Technology launch event to officially release the Shared Cloud Plan and discuss blockchain topics.
