hycInteresting attack on ETH mining twitter.com/yaish_aviv/status/1555445520646250496
-
hycmine a block with artificially high difficulty and faked timestamp, to keep diff adjust algo from dropping
-
hycthen proceed to mine many more blocks at lower difficulty than would otherwise be required
-
sech1no, they want high difficulty to make competing block an uncle (less paying)
-
sech1and their block taking the full reward
-
hycdoes that mean the attack only works when performed right before a difficulty adjustment?
-
hycand diff will adjust, regardless?
-
sech1from what I read, their diff adjustment works based on timestamp and starting from 9th second after the last block, it starts dropping
-
sech1very unsecure
-
sech1so f2pool fakes timestamp to avoid diff drop
