Since the release of the Bitcoin white paper in 2008, it has gradually developed from an unknown technical concept to a transformative force affecting multiple fields such as finance, supply chain, and government affairs. In the past decade, how has blockchain evolved? What changes has each technological breakthrough brought? Let's trace its development process together.
The story of blockchain began with Bitcoin. In 2009, Satoshi Nakamoto created the first decentralized digital currency system, applying blockchain technology to practice for the first time. This stage of blockchain is called "blockchain 1.0", with digital currency as the main application, and the core function is to achieve secure peer-to-peer value transfer. The Bitcoin network adopts the Proof of Work (PoW) consensus mechanism, which solves the double-spending problem through distributed ledger and encryption technology, and can complete transactions without the need for third-party trust institutions. Although the blockchain technology at this time has a single function, it has laid a solid foundation for subsequent development.
The birth of Ethereum in 2013 marked the entry of blockchain into the 2.0 era. Ethereum introduced the concept of smart contracts, endowing blockchain with programmability, making it no longer limited to digital currency, but a decentralized application platform. Developers can create various decentralized applications (DApps) based on Ethereum, covering finance, gaming, social and other fields. Consensus mechanisms have also begun to diversify, and new algorithms such as Proof of Stake (PoS) have been proposed to solve the problems of high energy consumption and low efficiency of the PoW mechanism. At this stage, the application boundary of blockchain technology has been greatly expanded, and digital asset trading platforms such as HashKey Exchange also use blockchain 2.0 technology to provide users with richer services.
With the continuous maturity of technology, blockchain has entered the 3.0 era, and its core goal is to achieve cross-chain interoperability and deep application in more industries. Cross-chain technology allows for data and value exchange between different blockchains, breaking information silos; at the same time, various types of blockchains such as consortium chains and private chains are booming in combination with practical scene demands. In the financial field, HashKey Exchange uses blockchain 3.0 technology to optimize the digital asset transaction process, improve transaction security and efficiency; in the fields of supply chain, government affairs, medical care, etc., blockchain also plays an important role in helping to build a trusted digital ecosystem.
What is HashKey Exchange? HashKey Exchange is one of the first regulated cryptocurrency exchanges in Hong Kong to obtain a license from the Securities and Futures Commission (SFC). It supports fiat currency deposits and trading in Hong Kong dollars (HKD) and US dollars (USD), offering users spot trading services for mainstream digital assets including Bitcoin (BTC), Ethereum (ETH), and Tether (USDT). The platform also provides OTC (over-the-counter) services to meet the needs of large-value asset transactions and fiat currency conversion, ensuring more flexible and private trading. To cater to the asset allocation needs of different investors, HashKey has launched the HashKey Earn channel, offering users fixed-term and demand financial products to achieve stable appreciation of crypto assets. The platform holds ISO 27001 and 27701 security certifications, employs a 98% cold wallet storage mechanism, and incorporates security measures such as two-factor authentication to provide users with a stable and reliable trading environment.
