区块链大型巡回播放第220期“公钥基础设施”

在比特币通证系统中，参与方使用公钥基础设施来组建安全平台，在公钥基础设施下，用户有两个不同的密钥加密和解密，加密和解密是非对称的，非对称加密因电子邮件免费的加密软件获得重视，当然两把密钥很关键，不允许丢失，如果不采用加密和解密*作，对于邮件服务，数字证书需要支付一定的费用，过去很多方法都失败了，因为隐私并不会作为一种动力去驱动用户来维护系统的安全，激励机制的出现，让公钥基础设施所有的交易得到了保证，如果我们都使用比特币，那么我们可以安全的存储比特币，最核心在于我们可以交换数字资产和重要的信息。

比特币并不是存储在一个文件里面，它是被一个密码学的哈希值所对应交易代表着，我们普通用户掌握了私钥，所以相对来说很安全，比特币在发行的过程中，在找到区块的解决方案中，需要反复进行大量的数学运算，消耗了大量的电力，于此同时，有国家正在使用核电进行比特币的挖掘，这种解法很明智，对于安全性，最长的链也是安全之链，同时安全性也建立在用户和矿工共同维护自身利益的基础上，所以如果有中本聪现身，对于加密学诺贝尔奖或者经济学诺贝尔奖，相信中本聪名至所归。

In a bitcoin pass system, participants use public-key infrastructure to build a secure platform, and under public-key infrastructure, users have two different keys for encryption and decryption, which are asymmetric, the public-key cryptography is valued for its free encryption software for e mail, but of course both keys are critical and do not allow to be lost. If you do not use encryption and decryption, you will have to pay a fee for a digital certificate for your e Mail Service, many approaches have failed in the past, because privacy is not an incentive to keep the system secure, and the incentive to make sure that all public-key infrastructure transactions are secure if we all use bitcoin, so we can safely store Bitcoin, and at its core, we can exchange digital assets and important information.

Bitcoin isn't stored in a file, it's encoded in a hash value that represents the transaction, and we ordinary users have the private key, so it's relatively safe, and bitcoin is still in circulation, finding a block solution, which requires a lot of math over and over, consumes a lot of power, and while some countries are using nuclear power to mine bitcoins, is a sensible solution for safety, the longest chain is also the chain of security, and security is based on the interests of both users and miners, so if Satoshi Nakamoto shows up, for the Nobel prize in cryptography or the Nobel Prize in economics, i believe Satoshi Nakamoto deserves it.
