And then -- this is the key part -- that block is linked to the previous block
隨后是關(guān)鍵的部分，該區(qū)塊連接到前一個(gè)區(qū)塊，
and the previous block to create a chain of blocks.
以及更前面的區(qū)塊，形成了一連串的區(qū)塊。
And every one is time-stamped, kind of like with a digital waxed seal.
每一個(gè)區(qū)塊都是時(shí)間標(biāo)記，有點(diǎn)像是數(shù)字蠟印。
So if I wanted to go and hack a block and, say, pay you and you with the same money,
假如說(shuō)我想要破解其中的一個(gè)區(qū)塊，比方說(shuō)給你還有你一樣的金錢，
I'd have to hack that block, plus all the preceding blocks,
我需要破解那個(gè)區(qū)塊和前面所有的區(qū)塊，
the entire history of commerce on that blockchain,
就是那區(qū)塊鏈上完整的交易歷史，
not just on one computer but across millions of computers, simultaneously,
并不只是破解一臺(tái)電腦，而是要同時(shí)破解數(shù)億臺(tái)電腦，
all using the highest levels of encryption,
它們都使用著最高級(jí)別的加密技術(shù)，
in the light of the most powerful computing resource in the world that's watching me. Tough to do.
世界上最強(qiáng)大的計(jì)算資源正在監(jiān)視著我。幾乎不可能的任務(wù)。
This is infinitely more secure than the computer systems that we have today.
比起我們現(xiàn)有的計(jì)算機(jī)系統(tǒng)，這絕對(duì)要安全得多。
Blockchain. That's how it works. So the Bitcoin blockchain is just one.
區(qū)塊鏈，這就是它工作的原理。而比特幣的區(qū)塊鏈只是其中之一。
There are many. The Ethereum blockchain was developed by a Canadian named Vitalik Buterin.
還有許多種類。以太坊區(qū)塊鏈由加拿大人維塔利·布塔林開發(fā)。
He is 19 years old, and this blockchain has some extraordinary capabilities.
他只有19歲。（實(shí)際年齡應(yīng)為22歲）這一區(qū)塊鏈有一些無(wú)與倫比的特點(diǎn)。
One of them is that you can build smart contracts. It's kind of what it sounds like.
其中之一是你可以制定智能合約。它正如其名。
It's a contract that self-executes, and the contract handles the enforcement, the management, performance and payment
它是自我執(zhí)行的合約，合約負(fù)責(zé)處理強(qiáng)制措施，經(jīng)營(yíng)管理，工作情況和支付方式，
the contract kind of has a bank account, too, in a sense -- of agreements between people.
某種意義上來(lái)說(shuō)，該合約也有一個(gè)銀行賬戶，是關(guān)于人們之間的協(xié)議。
And today, on the Ethereum blockchain, there are projects underway to do everything
如今，通過(guò)以太坊的區(qū)塊鏈，有各種工程進(jìn)行著各種任務(wù)，
from create a new replacement for the stock market to create a new model of democracy, where politicians are accountable to citizens.
從創(chuàng)造新的股票市場(chǎng)的替代品，到創(chuàng)立一個(gè)政客對(duì)公民真正負(fù)責(zé)的民主制度的新模型。
