The concept of Blockchain has already become the focus of global fintech talks. But what is Blockchain?

区块链已经成为全球互联网金融最为火热的概念,罢特,what is 区块链?

Traditionally speaking, there is always a database behind any system regardless of its size with the database being a massive ledger. For example, Taobao's database is like a massive ledger that records the account balance between user A and user B. If user A pays one Yuan to user B, then Taobao adds one Yuan to user B's account and deducts one Yuan from user A's account. Naturally, we can relate the update of a database to bookkeeping.

在传统情况下,无论大小系统背后都有一个数据库,数据库就像一个大的账本。比如某宝的数据库就像一个大账本,账上记录了A用户有多少钱、B用户有多少钱。如果A用户支付一元给B用户,那么某宝就在B用户账上加上一元,而在A用户账上减掉一元。所以也可以把数据库的变化看成是一种记账行为。

We often like to think that the person who is responsible for managing the system is the person responsible for managing the database, that no one else can be involve, and that our users from the Taobao example are unable to take part in the bookkeeping process.

我们通常认为谁维护系统,谁就天经地义的管理数据库,而其它使用者无权参与。就像某宝的用户无法参与具体的记账行为一样。

However, Blockchain can disrupt the traditional system, and allow every user to take part in the system.

但是区块链颠覆传统,让系统中每一个用户参与其中。

Blockchain is like a massive ledger that involves every user in the bookkeeping process. At a certain period in time, the system will select the fastest and most qualified user to update the account. The user then records the change on a block, as if writing on a piece of paper, and then distributing the copies to all the users in the system as backup. This is repeated in the next phase thus allowing all nodes in the system to have a copy of the most updated ledger.

区块链就像一个大的总帐本,系统中的每个用户都可以参与竞争记账。在某个时间段内,系统会在竞争者中找出记账最快最好的用户。该用户把这段时间内的数据变化写到一个区块中,就像写到一张账页上,并把这张账页复制给系统内所有其他用户进行备份,完成整个动作。在下个时间段周而复始,于是系统中每个节点都有着完整账本的副本。

Since every block of data is cryptographically chained together, we call it Blockchain or distributed ledger technology.

由于每个区块数据是通过密码学技术来链接在一起,所以我们称它为“区块链(Blockchain)”,或者 “分布式总账技术(Distributed Ledger Technology)”。

Blockchain allows everyone to take part in bookkeeping. There is no specific bookkeeper, and any node destroyed in the system will not affect its operation; everyone's account is thus more stable. The system defines the ledger with most similar data as the real ledger while the ledger with least similarity as the fake ledger; everyone's account is thus more secure. This makes it difficult for blockchain with enough nodes to be attacked or tempered. These nodes are distributed at every corner of the Internet. You would not be able to tamper anything unless you’re god and can control majority of the computers in the world. Therefore, the blockchain is considered to be the safest method for database management. Bookkeeping will be more efficient for everyone since there is no centralized intermediary, which means operations are automated and settings are pre-established, lowering cost and improving efficiency significantly, with verifications on each record and transparency throughout the ledger.

区块链,让全民参与记账。全民记账更稳定,由于系统中并没有特定记账人,系统中任意部分节点失联或者被摧毁,都不会影响系统的运行。全民记账更安全,系统规定相同数量最多的账本是真账本,少部分和其他用户不一致的账本即为假账本。这让具有足够多节点的区块链很难被攻击和篡改。这些节点分布在互联网的任意角落,除非你是上帝,能够控制全世界大部分电脑,否则无法篡改。因此区块链被认为有史以来最为安全的数据管理方式。全民记账更高效,由于没有中心化的中介机构存在,完全通过预先设定的程序自动运行,能够极大降低成本和提高效率,并且确保账本记录过程和内容公开透明。

Bitcoin is only one use case for payment transfer using the blockchain technology. Blockchain can be used on other industries such as health care, supply chain, Internet of Things, Identity, social media, and artificial intelligence. The Economist has referred Blockchain as the trusted machine, pointing out that the technology would be profound and impactful to the financial industry or even the social structure globally.

比特币只是区块链技术方案在支付领域的一个试验性应用,区块链还可以用于更加广阔的领域,医疗、供应链、物联网、安全认证、社交以及人工智能等领域都有它的身影。《经济学人》称区块链“信任的机器(the Trust Machine)”,认为它对于全球金融甚至是社会结构都会产生巨大且深远的影响。

To summarize, blockchain technology maintains a database of daily records in a reliable matter using cryptography in a multi-party environment without the need of a trusted intermediary. Now do you understand blockchain?

如果用一句话总结,区块链技术是在多方无需互信的环境下,通过密码学技术让系统中所有参与方协作,来共同记录维护一个可靠数据日志的方式。你懂了吗?
