比特币挖矿池容易消亡
加密资产分析网站 Coin Metrics 最近发表的研究指出，比特币矿池正处于“高消亡率”的状态。研究人员考察了 2011 年至 2019 年间的 37 个矿池(包括大型独立矿池)，发现许多曾经辉煌的矿池现在都已不复存在。
Bitcoin Mining Pools Are Fallible
Bitcoin mining pools are in "the high die-off rate", according to recently published research from crypto-asset analytics site Coin Metrics. The researchers looked at 37 mining pools (including large solo miners) from 2011-2019 and found that many once-prominent pools are now defunct.

我不认为以太坊经典（ETC）遭受了 51% 攻击就证明 以太坊（ETH）工程本身是有能力（抵抗51%攻击）的。两条链之间唯一的相关差异在于以太坊（ETH）的算力高出20倍。虽然这确实证明以太坊（ETH）哲学是具备（抵抗51%攻击）能力的，因为它验证了我们转向权益证明机制（PoS）的决定是正确的。
I don't think the 51% attack on ETC proves that ETH engineering is competent per se; the only relevant diff between the two is that ETH hashpower is 20x higher. Though it does prove ETH philosophy is competent, because it validates our decision to move to proof of stake.

ShapeShift 裁员37名。
“作为企业，我们犯过上千个错误。其中最严峻的是缺乏专注度。”--@ErikVoorhees
99%的企业都犯过这个错误。包括 ConsenSys 和 比特大陆。从此刻开始，重新调整企业愿景、将激情倾注于核心产品之上，继续前进。
ShapeShift laid off 37 employees.
"As a company, we’ve made a thousand mistakes. The most thematic has been a lack of focus." - @ErikVoorhees
99% of firms made same mistakes. ConsenSys & Bitmain included. From here, realign vision, aggressively focus on core products, move on.

我们通常听见的一个错误说法是以太坊区块链的大小已超过1TB。事实并非如此，事实上，目前链上数据的容量为138GB。我在ethhub.io上开了一个新页面，帮助大家认识这个错误说法的真面目。
地址：https://docs.ethhub.io/questions-about-ethereum/is-ethereum-over-1tb-in-size …
A very common myth we hear is that the Ethereum blockchain is over 1TB in size. This is not true and in fact the chaindata sits at 138gb today. I started a page on @ethhub_io to try and help dispel this myth.

51%攻击是不会发生的。
为什么……
1.法律-矿工如果这样做很容易就被认定为从事犯罪行为，且会被控告侵权和合同违约。
矿工的投资巨大，投入的规模达亿万美元甚至更大。
2.经济激励-矿工如果这样做，会降低他们从激励机制得来的利润，他们从事的这种这激励机制可以提供长期的利益。
比特币并不是加密保护技术-它甚至都没有加密。
它是一个经济激励系统。
矿工不会对比特币进行51%攻击，因为这对他们来说没什么经济性的好处。
这也是为什么只有比特币能存在（只要一条区块链），并且是唯一的协议。
There is NO 51% attack.
Why...
1. Law - a miner doing this is an easy target for criminal action and can easily be taken to task in both Tort and contract.
Miners have a HUGE investment. 100s of millions of USD at scale or MORE
2. Economic incentives - if the miner does this, they lower the profitability of the very investment they have a long term interest in building.
Bitcoin is NOT at all about cryptographic protections - it is NOT even encrypted.
It is an economic incentive system.
Miners do not do 51% attacks on Bitcoin as it is not economically viable for them to.
This is also why ONLY one Bitcoin can exist (only one Blockchain) and only ever one protocol.

以太坊经典（ETC）自称攻击他们链的大可能是自私挖矿攻击。
实际上，自私挖矿可以用来降低双重花费攻击的成本。这样做可以使攻击者花费的哈希算力变少，但是代价是攻击成功的概率也降低。
鉴于一些我从别人那里听到的消息，我怀疑这次攻击不是自私挖矿，但也只有仔细调研才能得出最准确的结论。
Ethereum Classic said that the attacks against their chain were most likely Selfish Mining attacks.
Indeed, selfish mining can be used to reduce the cost of a double-spend attack. The trade-off is that the attacker needs less hashpower, but sacrifices some success probability.
Given what I've heard from others, I suspect this was not SM, but only a careful post-mortem can tell.
