如果我创建了自己的新闻网站，我会定条规则，所有发生在168小时以内的事件和资讯都不准发。
实际上，大多数的事情在一周后知道并没什么影响，而且我认为经过时间洗礼的报道质量会更高，内容也更好。
If I ever made my own media site, I would have a rule that no articles are allowed about events/info that came out less than 168 hours ago.
Realistically there's little harm in learning most things a week later and I feel reporting would be higher quality and healthier that way.

Charlie Lee
莱特币创始人
1）莱特币的早期研发阶段（2011年），莱特币经受着51%攻击的威胁。为了保护莱特币的安全，我在系统中引入了检查点（checkpoint）。检查点是一个中心化的功能，因为它依赖于开发员来决定哪条链是有效链。但这对于一枚币的早期阶段来说，这样做是合情合理的。
2）莱特币用一点中心化的代价，换取了网路的稳定性和可靠性。中本聪在一开始也在比特币网络中采用了检查点。虽然，你可以说这种做法类似于UASF，也即用户可以自行决定是否运行或升级到最新的检查点。
「Unitimes注：UASF 用户激活的软分叉(user-activated soft fork)」
3）我也考虑过采取行动防止代码中出现大型的重组错误，但我最后还是决定不去这么做。我不这么做的原因跟中本聪为什么不防止比特币出现重组错误的原因是一样的，中本聪在一封邮件里面对此进行了很好的解释。
4）如果你想要用与主链网络一致的共识规则来启动一个新节点，那么你必须认同正确链上面其他的节点都是有效的。整个去中心化共识基本上默认检查点前的信息都是真实可信的。
5）如果不能保证检查点的真实有效，那么这个网络就不是去中心化的网路，因为你必须信任那个告诉你哪条链是正确的的人。去中心化和“健全货币”的总体意义在于，你不需要去信任任何人。
1/ In the early days of Litecoin (2011), there were threats of 51% attacks. To keep Litecoin secure, I utilized checkpoints. Checkpointing is a centralizing feature as it relies on the developers deciding which is the right chain. But for the beginning of a coin, it made sense.
2/ It's trading off some centralization for network stability and reliability. Satoshi also used checkpoints in Bitcoin in the beginning. Though one can say that it is similar to the idea of UASF as users can decide whether or not to run or upgrade to the latest checkpoints.
「Unitimes：UASF = user-activated soft fork」
3/ I have also considered preventing large re-orgs in the code but decided against it. There is a very good reason why I didn't do this in Litecoin and why Satoshi didn't do it for Bitcoin. Satoshi said it best in one of his emails. https://satoshi.nakamotoinstitute.org/emails/cryptography/6/
4/ If you spin up a new node with the same consensus rules as the network, you need to come to the same conclusion as the rest of the network as to which is the right chain. The whole decentralized consensus is pretty much based on this simple fact to be true.
5/5 If this is not true, then it's not decentralized as you have to trust someone to tell you which is the right chain. The whole point of decentralization and sound money is that you don't have to trust anyone.

BTCC联合创始人&CEO
钱，一直以来要么是以物理形式（硬币、纸币、黄金）呈现，要么是以账户且与实名身份相挂钩（银行账号）的形式呈现。
而比特币，是人类历史上第一次，金钱以“信息”的载体形式出现：没有任何实体，也不与任何身份挂钩。
Money has always been either Physical in nature (coins, bills, gold), or Account-based, and thus tied to real-name identity (bank accounts).
With Bitcoin, for the first time in human history, money is now just #Information: nothing physical, and not tied to any identity.

看着那些废弃硬件堆的图片，不少人会对比特币挖矿造成的“浪费”感到愤怒。想一下任何类型的挖矿业务，以及它们所造成的混乱和“浪费”。那这是一个去中心化金融体系必须的成本吗？是的。浪费了吗？不尽然。
Quite a few are livid about the "waste" of Bitcoin mining, seeing pictures of abandoned piles of old hardware. Consider any kind of mining, and the mess and "waste" it creates. Is it a cost of a decentralized financial system? Yes. Is it waste? Not necessarily.

BCH 一直都是随人们自愿购买的，而 BSV 则一直威胁人们，如果他们继续待在 BCH 链上，就要进行区块重组和偷走他们的钱，从而迫使人们转换到他们的链上去。
BCH was always voluntary, but BSV is forcing people onto their chain by threatening to re-org and steal people's money if they continue on the voluntary chain.
