01:35:17 Section 3.2 of https://www.cs.princeton.edu/~arvindn/publications/mining_CCS.pdf mentions a strategy of delaying the start of mining a new block since tx fees are delayed. Are there any mining impls (whether Monero, Bitcoin, or otherwise) that implement that? For Monero I'd imagine any theoretically profitable delay would be small with current fees, on the order of <10s. 01:36:30 Actually < 2s for Monero.
