15:53:58 <hyc> Interesting attack on ETH mining https://twitter.com/yaish_aviv/status/1555445520646250496
15:55:21 <hyc> mine a block with artificially high difficulty and faked timestamp, to keep diff adjust algo from dropping
15:55:47 <hyc> then proceed to mine many more blocks at lower difficulty than would otherwise be required
16:24:10 <sech1> no, they want high difficulty to make competing block an uncle (less paying)
16:24:21 <sech1> and their block taking the full reward
16:31:10 <hyc> does that mean the attack only works when performed right before a difficulty adjustment?
16:31:28 <hyc> and diff will adjust, regardless?
16:36:40 <sech1> from what I read, their diff adjustment works based on timestamp and starting from 9th second after the last block, it starts dropping
16:36:44 <sech1> very unsecure
16:37:03 <sech1> so f2pool fakes timestamp to avoid diff drop
