BGIN Tapes Out 4nm Bitcoin Mining ASIC BT1—Seventh Straight Success

BGIN just hit another milestone. The Nasdaq-listed company announced the first successful tape-out of its BT1, a 4nm Bitcoin mining ASIC—its first proprietary chip for BTC mining. The project entered tape-out in October 2025 and nailed it on the first try.

The chip is now moving into system-level testing and production prep. This marks BGIN's seventh consecutive successful tape-out since 2022—a clean sheet in ASIC execution.

BGIN says the win lowers development risk and strengthens confidence in its multi-gen mining roadmap. It's already working on next-gen architectures to squeeze out better energy efficiency. The mining chip race keeps heating up.
