Bitcoin developer Kevin Loaec, who flagged the danger on X this week, stated massive holders might be focused first. Doing nothing will probably be a safer choice, he acknowledged, as cash that by no means transfer can’t be replayed as a result of there is no such thing as a signed transaction to repeat.
IMPORTANTIn the following couple of days, a brand new shitcoin will fork off Bitcoin. It’s a massive safety threat for individuals who simply imagine they’ll get an “airdrop” and wish to promote it, to get extra bitcoin.
I’ll write extra about it, however right here is the TLDR:— Kevin Loaec (@KLoaec) August 6, 2026
How BIP-110 makes this attainable
The explanation any of that is taking place is a proposal referred to as BIP-110, which might maintain footage, textual content and different non-payment information out of bitcoin transactions for a 12 months.
Altering bitcoin’s guidelines requires miners to agree, and so they register that settlement by marking the blocks they produce. BIP-110 wants 1,109 marked blocks out of a 2,016-block stretch, or 55%. (A block is the batch of transactions miners add to the ledger roughly each ten minutes.)
That route is closed however the proposal has a second one written into it. From block 961,632, anticipated this weekend, computer systems working BIP-110 software program will reject any block that doesn’t carry the mark, whether or not miners agreed or not.
Virtually each block being mined proper now doesn’t carry it. So these computer systems will begin rejecting the chain that just about all of bitcoin’s mining energy is constructing.
If some miners proceed constructing a BIP-110-compatible department whereas the remainder maintain mining bitcoin as traditional, two competing variations of the transaction historical past may emerge. It stalls if no one retains extending the minority department, it stalls.
