Ethereum co-founder Vitalik Buterin cautioned that a blockchain’s key security assurance is that even a 51% attack cannot turn an invalid block into a valid one, meaning colluding validators are unable to steal users’ assets. However, he clarified that this guarantee doesn’t apply off-chain in external trust situations, if 51% of validators act together, users are left without recourse.

A solo miner successfully mined a Bitcoin block using equipment worth up to $300. An unknown lucky miner mined block #887212 using a home setup from Bitaxe (priced between $150 and $300) with a hash rate of 480 GH/s. For comparison, this is only 1/27th of the hash rate of an old Antminer S9 from Bitmain. The miner earned 3.17 BTC (about $246,501, including fees). According to CKPool administrator Con Kolivas, the chance of mining a block with such power is less than 1 in a million.
