Jack Dorsey's company, Block, has introduced a significant advancement in Bitcoin (BTC) mining technology by completing its three-nanometer (3nm) mining chip.

This achievement follows the earlier prototype of a five-nanometer chip. The new chip aims to enhance efficiency and decentralization in Bitcoin mining, particularly as the industry transitions into the fifth mining epoch post the fourth halving of the block subsidy.

Building on insights gained from the tested 5nm chip prototype, Block has refined the 3nm chip to improve performance and support mining operators in a highly competitive market. Additionally, Block is developing a comprehensive mining system, leveraging its expertise in product development, software engineering, supply chain management, and customer support.

This system is designed to introduce innovations in mining hardware form factors and applications, addressing various miner needs. Block is actively seeking feedback from the mining community to further refine its products and enhance its mining hardware solutions.
