以太坊核心开发者
我们要在区块高度为7280000左右进行君士坦丁堡硬分叉，时间是2月27日。将在主网进行分叉，在测试网进行君士坦丁堡更新后的修复分叉，使之恢复到与主网一致的正常功能。
Seems we're going with block 7.28M for the #Ethereum Constantinople refork scheduled for the 27th of February! Will be a single fork on mainnet and a post-Constantinople-fixup fork on the testnets to get them back in line feature wise with the main network.

【以太坊死忠粉 Evan Van Ness：我们曾以为51%攻击会永久性地终结一条区块链的价值。而虽然 ETC 受到 51%攻击，但价格没怎么变。】
我觉得这是因为人们错误的地认为51%攻击意味着攻击者可以“盗走所有人的钱”，其实其潜在的损害没那么严重-它主要针对的是特定的交易。
【Evan Van Ness：We used to think a 51% attack would permanently end a blockchain's value. Then ETC got 51% attacked and the price didn't move.】
I think that is because people wrongly think that 51% attacks mean attackers can "steal everyone's money", where the reality of potential damage is much more mundane - mainly targeted at specific transactions.
