Right after I sent that email AntPool mined multiple V3 transactions: 774ed3c3760a859bf1cc4f6b11829807b19cacbe3045348694f1b6deff13720b a1f5d87ad33fb38b2bf950ae712cbcefb0f91f8e951c4f6bb2e825af88ae25a9 a4c3637cddb10ab3b99a7a27c5356952a1a756ccfa4cf06569d8de9c351415a9 1449ab8fb32e3c7664276f8c6e320e478ff44e1599c44d3dfb6ec6607c45ef26 Mining pools often split up their block template creation across multiple nodes, so it's quite possible that I just got unlucky. Or maybe someone at AntPool noticed my email and upgraded one or more of their nodes. Based on the available data all I can say for sure is that ViaBTC, SpiderPool, Binance Pool, BTC.com, and Luxor seem to *not* be mining V3: a4c3637cddb10ab3b99a7a27c5356952a1a756ccfa4cf06569d8de9c351415a9 e6469be8344aabe4758fc420279e764e784f6371f9df0a8fb1e463809dd765cb 35a49bf34f5af21d295a1d19d5d557251f6caa02e640457c73f921ddd9186ecb It'd be interesting to compare these findings to the accusations that many other pools are just a proxy for AntPool... I've got better things to do with my time right now. But I'll leave the experiment running for a bit longer. :) -- https://petertodd.org 'peter'[:-1]@petertodd.org -- You received this message because you are subscribed to the Google Groups "Bitcoin Development Mailing List" group.
