Block’s 3nm Bitcoin Mining Chip Reaches Tape-Out; MARA Launches Landfill-Gas Mining Pilot; Boyaa to Allocate All Web3 Profits to Bitcoin
ME News, April 7 (UTC+8) — BBX crypto-related equities disclosures show the sector pushing two themes: greater decentralization of mining hardware and a sharper shift of corporate cash flow into Bitcoin. Payment and mining firms are advancing proprietary silicon and off-grid energy strategies, while listed companies are moving to Bitcoin-first treasury policies.
Block, Inc. (NYSE: $SQ) said its in-house 3-nanometer (3nm) Bitcoin mining chip has successfully completed tape-out. Built for decentralized mining with ultra-low power consumption and an open-source architecture, the chip targets the dominance of incumbent high-efficiency hardware makers. Related systems are expected to begin shipping to small-to-midsize and home miners in Q3 2026.
Boyaa Interactive International Limited (HKG: $0434) said its board has approved directing 100% of net profits from future Web3 games and related applications to Bitcoin purchases, with holdings transferred to cold-wallet reserves. The company is positioning the move as a full-allocation treasury approach, minimizing fiat exposure and holding reserves in Bitcoin.
Marathon Digital Holdings, Inc. (NASDAQ: $MARA) announced a new "Energy Harvesting" division and launched its first landfill-gas (methane) mining pilot in Utah. The project captures and combusts methane to generate electricity for mining, aiming to cut emissions while lowering energy costs.
Cipher Mining Inc. (NASDAQ: $CIFR) disclosed it has completed the acquisition of a 150MW standalone wind farm in Texas. The company plans to deploy containerized mining units on-site to run fully off-grid, seeking to avoid ERCOT peak-shaving directives and transmission and distribution charges.
Semler Scientific, Inc. (NASDAQ: $SMLR) provided a first-quarter business update and said it continues to use excess free cash flow from core medical device sales to buy Bitcoin. The company described the strategy as "fiat generation, digital savings," using its crypto treasury as an inflation hedge for healthcare supply-chain costs through 2026.
