A race-of-work (RoW) system is an upgrade to proof-of-work system, invented by Ilya Gazman. It's a competition between miners seeking for the smallest hash possible in predefined block time. ROW avoids accidental forks by having a diplomatic vote to void delayed blocks, by doing so it become resistant to 51% attack as there is no way to drop accepted blocks.
Background[edit | edit source]
ROW was invented as an answer to POW instability, the inability to predict the exact time it takes to mine a block. On one occasion in Bitcoin: block 152218 followed block 152217 after a delay of 1 hour 39 minutes and 7 seconds, instead of expected 10 minutes.
