In the traditional chip development industry, it typically takes up to two years to transition a chip from the design phase to a finished product. For example, developing mining rigs for Sia and Decred required approximately 13 months from project initiation to product delivery. If we were to undertake a similar project again, we estimate that timeline could be shortened to under nine months.
A significant portion of this development time is dedicated to the full-custom routing of the chip. There is a faster alternative known as "place-and-route," which can reduce development time by about three months. However, chips produced using this method tend to be two to five times slower than those developed by a team employing full-custom design. We believe that using the place-and-route approach could allow us to deliver a product within six months.
Industry observations suggest that Bitmain took roughly five months to develop its A3 miner, while Halong Mining likely spent about nine months creating the B52 miner. It is suspected that both companies utilized the place-and-route design methodology, which aligns with the relatively lower performance of these machines.
When creating a chip from scratch, the timeline is extensive. However, targeting a hard fork significantly shortens this process. If a manufacturer anticipates the need for a redesign, numerous shortcuts can be taken to reduce time-to-market. Modifying an existing design to accommodate an algorithm adjustment is much faster than starting from zero. A skilled team with robust infrastructure could complete such a redesign in as little as two weeks.
If production is prioritized at the factory, new chips could be ready in approximately 40 days. After that, about a week is needed for packaging before shipment to the manufacturer for assembly. Finally, the finished miners must be delivered to data centers to begin operation.
Assuming all wafers, components, and other necessary materials are pre-ordered, upgrading a chip to adapt to a hard fork and enabling miners to operate under a new hashing algorithm could theoretically be achieved in around 70 days. In practice, however, companies like Bitmain might require three to four months to adjust an existing chip for a hard fork. Without on-hand wafer inventory, this could extend to four or five months. For any other company besides Bitmain, these timelines could increase by an additional 30 to 60 days.

Understanding the Development Timeline
Creating a mining rig involves multiple stages, from initial design to mass production. Each phase requires careful planning, technical expertise, and coordination with manufacturing partners. Manufacturers often balance speed with performance, choosing between full-custom and place-and-route methods based on their goals.
The Impact of Hard Forks on Manufacturing
Hard forks—significant changes to a blockchain’s protocol—often require mining hardware upgrades. Manufacturers that anticipate these changes can respond more swiftly. Preparedness includes pre-booking production capacity and maintaining strategic component inventories.

Frequently Asked Questions
How long does it typically take to develop a new mining rig?
Developing a new mining rig from scratch usually takes between 9 to 13 months. This timeline includes design, testing, and production. Using faster methods like place-and-route can shorten this period but may reduce performance.
What is the difference between full-custom and place-and-route design?
Full-custom design involves manually optimizing each part of the chip for maximum performance, which takes longer. Place-and-route uses automated tools to speed up development but often results in slower, less efficient chips.
Can manufacturers quickly adapt to blockchain hard forks?
Yes, with adequate preparation. If a manufacturer anticipates a hard fork, it can modify existing designs in as little as two weeks. However, production and delivery typically add several months to the process.
Why might some companies respond faster to hard forks than others?
Larger companies like Bitmain benefit from economies of scale, established supply chains, and pre-booked production capacity. These advantages allow them to adapt more quickly compared to smaller manufacturers.
What role does inventory play in production speed?
Having wafers and components in inventory significantly shortens production time. Without inventory, manufacturers must wait for new orders, extending the timeline by weeks or even months.
Is it possible to further reduce these timelines in the future?
Advancements in automation, design software, and supply chain management may further reduce development and production times. However, physical manufacturing and logistics constraints will always impose certain limits.
