Foundry USA Pool Begins Stratum V2 Testing, Allowing Miners to Choose Transactions

Foundry USA Pool's Stratum V2 testing shifts a core piece of block construction from the pool to individual miners, a meaningful change for a mining sector where transaction selection has largely been centralized at the pool level. The significance is less about any single block and more about precedent: if the testing phase holds up, it could alter how miners relate to the pools that coordinate their hashpower. Whether other large pools follow, and whether miners actually exercise the new autonomy rather than defaulting to pool templates, is the open question.
