When Miners Collide: Foundry's Seven-Block Streak Leaves AntPool and ViaBTC in the Digital Dust

Foundry USA Pool just executed a Bitcoin power move so slick it would make a maximalist blush. They out-muscled rivals AntPool and ViaBTC, extending their own blockchain branch until the competitors' blocks were unceremoniously kicked from the canonical chain like a bad NFT from a profile pic frame.

The blockchain drama unfolded like a high-stakes, low-latency soap opera. Multiple miners hit valid blocks nearly at the same time, creating a temporary network fork—the crypto equivalent of a traffic jam at the merge. Foundry mined block 941881 while AntPool mined a competing block at the same height. Not to be left out, ViaBTC then piled onto that competing chain with block 941882.

Meanwhile, Foundry, refusing to let its hard work go to waste, kept chipping away at its own branch, producing an alternative version of block 941882. This triggered Bitcoin's cold, unfeeling consensus rules, which simply select the chain with the greatest cumulative proof of work—survival of the fittest, with more hashes.

Then, Foundry went full degen mode, embarking on a legendary mining spree and producing seven blocks in a row. This made their branch the undisputed heavyweight champion, forcing network nodes to accept it. The competing blocks from AntPool and ViaBTC became stale, valid but ultimately forgotten blocks, left outside Bitcoin's canonical ledger like transactions with too-low gas fees.

This event was a two-block reorganization, a scenario where a temporary tie between competing branches persists for more than one block before a winner is crowned. While single-block reorgs are the occasional network burp, two-block events are rarer, a known but spicy outcome of near-simultaneous block discovery and the normal, slightly chaotic gossip of network propagation.

Crucially, for any anxious bag-holders watching, transactions in those orphaned blocks weren't necessarily lost to the void. They either already existed, chilling in the winning chain, or were gracefully returned to the mempool to wait for another shot at inclusion—think of it as a transaction's second chance at life.

The entire episode serves as a masterclass in Bitcoin's built-in fork resolution mechanism. The network operated exactly as its pseudonymous creator intended, dispassionately favoring the chain with the greatest cumulative proof of work. It's a beautiful, if brutally efficient, system.
