Block's Open-Source Nano Chip the Future of Bitcoin Mining

Block, the financial services and technology company owned by former Twitter CEO Jack Dorsey, has announced that it has completed the prototype design of its new five-nanometre (5nm) Bitcoin mining chip.

This chip is a crucial step towards decentralizing the supply of Bitcoin mining rigs, which is currently heavily concentrated in the hands of a select few companies.

Decentralizing Bitcoin Mining

Block has been pushing for a more decentralized approach to Bitcoin mining for some time, and its new 5nm chip is the latest step in this direction.

According to the company, they intend to enhance innovation and expand the Bitcoin mining hardware ecosystem by making Bitcoin mining technology open source by selling separate ASICs and hardware components.

Open Source Mining Technology

Block aims to open source its new Bitcoin mining technology and make it available to as many people as possible.

This will allow the company to experiment with new designs and aid in bringing more efficient and affordable Bitcoin mining chips to the market.

Block has purchased a large batch of ASIC chips from Intel to fast-track this development push.

The company claims its proprietary 3nm chip, which it plans to release, would be the most advanced chip to date.

The timing of the purchase is advantageous since Intel recently announced that it would discontinue taking orders for its Blockscale 1000 Series ASICs on Oct. 20 and cease shipping by April 2024 to reduce costs. This gives Block an advantage over competitors by having a readily available supply of the older chips.

A nanometer (1nm) is about the width of two silicon atoms, enabling the placement of more transistors on a silicon die of the same size as chips get smaller.

Decreasing the circuit size reduces the distance traveled by the electric current to perform a calculation, improving efficiency and decreasing heat production.

5nm ASIC Chips Already Exist

5 nanometre ASIC chips have been around for some time. The earliest 5nm ASIC was released in 2021 by Chinese mining firm Canaan.

At present, 5nm chips power the majority of Bitcoin mining ASICs, but no company has yet shared their ASIC chip designs as open source.

Block’s chip is expected to be a game-changer in the Bitcoin mining industry. Its small size, energy efficiency, and advanced security features make it a highly attractive option for miners.

Moreover, by making Bitcoin mining technology open source where possible, Block is promoting innovation and competition, which can only be good for the industry as a whole.

With the first prototype of the chip now complete, it is only a matter of time before we see it in action.
