【精讲文本】

Bitcoin may be the currency of choice, but it’s blockchain, the technology that supports it, that has everyone talking.
比特币是否会成为人们首选的货币或许还不一定，但比特币所基于的区块链技术，现在成为很多人关注的焦点。

blockchain: 区块链

是比特币（BitCoin）技术中的核心部分，其功能简单而言类似于一种账本，记录所有的交易数据。简而言之，区块链（Blockchain)就是通过去中心化和去信任的方式集体维护一个可靠数据库的技术方案。
作为一种P2P形式的数字代码，比特币(BitCoin)不依靠特定货币机构发行，而是依据特定算法，通过大量计算产生。

“Every blockchain transaction is open on this big public ledger. So it’s kind of like if you share an Excel file with a group of your employees at the office. Every time that you update the file, it gets updated on every other computer.”
“每次的区块链交易都是在这个公开的大分类账簿上开放的。所以这样就像在办公室里，你跟一群员工分享一个Excel文件。你每次更新文件时，其他计算机上的文件也会相应地进行更新。”

ledger: n. 总账，分户总账；[会计] 分类账；账簿；底账；（手脚架上的）横木

-Looking for the current ledger balance, you can rigorously specify which balance you want.
寻找当前的分类帐余额，您可以精确指定想要的余额。

Bitcoin uses blockchain technology to enable anonymous, peer-to-peer payments, which is why the digital currency is often associated with illicit activity. But developers are realizing the same technology can be applied elsewhere.
比特币利用区块链技术来实现匿名的对等支付，这就是为什么数字货币往往与非法活动产生联系。但开发人员逐渐意识到，这项技术也可以应用在其他领域。

Blockchains eliminate the need for intermediary parties, by relying on a decentralized network of computers, or nodes, to verify transactions.
区块链通过依靠分散的计算机网络或节点来进行交易验证，从而不需要中间方的介入。

eliminate: vt. 消除；排除

-Snickers will replenish your energy and eliminate your hunger immediately.
士力架能帮你迅速补充体力，消除饥饿感.

Intermediary:
adj. 中间的；媒介的；中途的
n. 中间人；仲裁者；调解者；媒介物

哈德森•詹姆森帮助开发了一款汽车硬件和软件平台，这一平台基于以太坊区块链技术。“我们将以太坊网络节点设计在一款特斯拉(Tesla)汽车中，所以每当它通过收费桥的时候，以太坊节点或汽车就会与收费桥形成交互，并自动支付过桥费。所以，你可以想一下今天的收费桥，你必须用信用卡支付交易费用。但是我们研发的系统，可以实现机器对机器的自动交易。”

Transactions are processed on the spot without going outside of the network.Companies like Toyota, United Health Group and Fidelity are exploring blockchain and in part lending it legitimacy.
这种机器对机器的通信，使得直接使用存储在数字钱包中的数字货币成为可能。交易可当场进行处理，不经外网。像丰田、联合健康集团和富达国际这样的公司正在探索发展区块链技术，某种程度上，增强了区块链的正统地位。
