比特币 VS 以太坊：道不同不相为谋
未来，区块链技术将不单单用于数字货币的应用程序，我们将这种升级产品称之为Crypto 2.0,Blockchain 2.0甚至是Bitcoin 2.0。
Ethereum has received a lot of attention since its announcement at the North American Bitcoin Conference in early 2014 by Vitalik Buterin. The natural consequence of its rising popularity has been its constant comparison to Bitcoin, the first virtual currency. It is important for investors to understand the similarities and differences between Bitcoin and Ethereum.
Bitcoin, the first virtual currency, was born seven years back. It introduced a novel idea set out in a white paper by the mysterious Satoshi Nakamoto: Bitcoin offers the promise of lower transaction fees than traditional online payment mechanisms and is operated by a decentralized authority, unlike government issued currencies. There are no physical Bitcoins, only balances associated with public and private keys.
Over these years, the acceptance of the concept of a virtual currency has increased among regulators and government bodies. Although it isn’t a formally recognized medium of payment or store of value, it has managed a niche for itself and continues to coexist in the financial system despite being regularly scrutinized and debated.
The attempts to understand Bitcoin more closely resulted in the discovery of blockchain, the technology that powers it. The blockchain is not just the hottest topic in the FinTech world but also a sought after technology in many industries.
A blockchain is a public ledger of all transactions in a given system that have ever been executed. It is constantly growing as completed blocks are added to it. The blocks are added to the blockchain in linear, chronological order through cryptography, ensuring they remain beyond the power of manipulators. The blockchain thus stands as a tamper-proof record of all transactions on the network, accessible to all participants. The blockchain offers a chance to work at lower costs with greater regulatory compliance, reduced risk, and enhanced efficiency.
Blockchain technology is being used to create applications which are beyond just supporting a digital currency. Such applications are often referred to as Crypto 2.0, Blockchain 2.0 or even Bitcoin 2.0.
Launched in 2015, Ethereum is the largest and most well-established, open-ended decentralized software platform that enables SmartContracts and Distributed Applications to be built and run without any downtime, fraud, control or interference from a third party. Ethereum is not just a platform but also a programming language (Turing complete) running on a blockchain, helping developers to build and publish distributed applications.
The potential applications of Ethereum are wide ranging and run on its platform-specific cryptographic token, Ether. In 2014, Ethereum had launched a pre-sale for ether which received an overwhelming response. Ether is like a vehicle for moving around on the Ethereum platform and is sought by developers looking to develop and run applications inside Ethereum.
Ether is used broadly for two purposes: it is traded as a digital currency exchange like other cryptocurrencies and is used inside Ethereum to run applications and even to monetize work. According to Ethereum, it can be used to “codify, decentralize, secure and trade just about anything.” One of the big projects around Ethereum is Microsoft’s partnership with ConsenSys which offers “Ethereum Blockchain as a Service (EBaaS) on Microsoft Azure so Enterprise clients and developers can have a single click cloud-based blockchain developer environment.”
Bitcoin Vs Ethereum
While both Bitcoin and Ethereum are powered by the principle of distributed ledgers and cryptography, the two differ in many technical ways. For example, the programming language used by Ethereum is Turning complete whereas Bitcoin is in a stack based language. Other differences include block time (Ethereum transaction is confirmed in seconds compared to minutes for Bitcoin) and their basic builds (Ethereum uses ethash while Bitcoin uses secure hash algorithm, SHA-256).
However, from a general point of view, Bitcoin and Ethereum differ in purpose. While Bitcoin is created as an alternative to regular money and is thus a medium of payment transaction and store of value, Ethereum is developed as a platform which facilitates peer-to-peer contracts and applications via its own currency vehicle. While Bitcoin and Ether are both digital currencies, the primary purpose of Ether is not to establish itself as a payment alternative (unlike Bitcoin) but to facilitate and monetize the working of Ethereum to enable developers to build and run distributed applications.
The Bottom Line
In sum, Ethereum is an advancement based on the principle of blockchain that supports bitcoin but with a purpose that does not compete with Bitcoin. However, the popularity and rising market capitalization of Ether brings it in competition with all cryptocurrencies, especially from the trading perspective. Currently, the market cap of Ether (ETH) is more than Ripple and Litecoin although it’s far behind Bitcoin (BTC). On the whole, Bitcoin and Ethereum are different versions using the blockchain technology, and are set to establish themselves, driven by different intentions.
