&gt; The given rationale for a difficulty reset was to let developers occasionally mine blocks on their laptop.<br /><br />It is technically possible to allow CPU users to get some coins, if they provide some Proof of Work.<br /><br />Example Script: "OP_SIZE 60 OP_LESSTHAN OP_VERIFY 0279be667ef9dcbbac55a06295ce870b07029bfcdb2dce28d959f2815b16f81798 OP_CHECKSIG".<br /><br />Related topic: https://delvingbitcoin.org/t/proof-of-work-based-signet-faucet/937<br /><br />And because this method is network-independent, and can be deployed anywhere (all testnets, mainnet, signet, regtest, doesn't matter), then it is probably a good idea to disable 20 minute rule, that way or another.<br /><br /><div class="gmail_quote"><div dir="auto" class="gmail_attr">poniedziałek, 24 marca 2025 o 02:29:17 UTC+1 Murch napisał(a):<br/></div><blockquote class="gmail_quote" style="margin: 0 0 0 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">Hey Antoine and everyone,
<br>
<br>What you suggest makes sense to me. Since the 20-minute difficulty 
<br>exception is now exploited perpetually, it doesn’t serve its intended 
<br>purpose of allowing developers to mine themselves a few coins easily or 
<br>confirm their own non-standard transactions. In that case, it would be 
<br>better to not have it at all.

<br>I would suggest to pick a date that’s not a holiday in many places to 
<br>avoid disrupting people’s holiday, how about 2026-01-01 instead?
