The international chip shortage has had a big impact on IT and knowledge facilities in every single place. At least one contributor to the shortage is the rising software of blockchain expertise, which consumes a considerable share of chip manufacturing consequently of its compute-intensive nature.
How consequential the chip shortage is perhaps and the way lengthy it would final are amongst the questions regarding IT practitioners and trade watchers alike.
Chip provide and demand
“Blockchain should be thought of as an application that runs on servers. And servers, in turn, run operating systems using microprocessor chips to provide processing power,” stated Ron Howell, software-defined WAN and Secure Access Service Edge architect for Capgemini America. There are solely so many microprocessor chips out there, they usually go to the highest bidders. Blockchain requires excessive numbers of distributed processing engines to function successfully.
“The popularity of cryptocurrency adds to the high demand for chips and contributes to the shortages we see today,” Howell stated.
While demand for semiconductors elevated 17% from 2019 to 2021, there was no commensurate improve in chip provide.
The overwhelming majority of semiconductor fabrication crops already function at about 90% of their capability to fabricate chips, which means they’ve little rapid means to extend their output, in line with current research.

“It is getting worse, and the effect is a slowing of the economy overall,” Howell stated. “The need for chips is expected to increase, as technologies that use vast amounts of semiconductors, like blockchain processing, cryptocurrency growth, 5G and electric vehicles, become more widespread.”
It boils down to provide and demand: There is at the moment extra demand than provide for particular microprocessor chips. Some corporations now stockpile chips in order to construct their merchandise for market.
Supply chain points
Some estimate that total provide chain constraints and shortages will final one other two years, till all the further fabrication capability comes on-line, stated Greg Schulz, founder and consulting analyst at Server StorageIO.
“All of a sudden, we needed more chips, but increasing production depended on expanding the factory, and that takes time to build,” Schulz stated.
That gradual response ripples up the provide chain, with the tools that produces the chips now in quick provide — tools that itself usually requires chips, producing a chicken-and-egg state of affairs.
Some of the disruption might be attributed on to the COVID-19 pandemic, however Schulz additionally believes there was too little funding in the sector to arrange to satisfy demand.
“The surge in all of these things, whether it is memory chips or general-purpose chips or GPUs or RISC or Arm chips — it is easy to point the blame at COVID, but COVID only exacerbated the situation,” Schulz stated. “You suddenly had more people who needed smart devices and computers, and on the production side, you had workers who couldn’t go to work.”
Although loads of chip manufacturing is automated, human involvement stays necessary.
Use circumstances for GPUs
For Chris Mattmann, chief expertise and innovation officer at NASA’s Jet Propulsion Laboratory, the greatest half of blockchain’s affect on the chip shortage is, in reality, its in depth use of GPUs. In the previous, GPUs have sometimes been reserved for complicated mathematical operations and AI processing.
“As it turns out,” Mattmann stated, “these chips also are quite useful in blockchain, since part of the design of the blockchain calls for dynamic new blocks to be written by linking the new blocks of transactions to previous blocks.”
The act of creating new blocks includes hashing and competing to seek out the finest, quickest and most resilient hash code. Hash code is pc code that capabilities as a compact illustration of a chunk of knowledge that may symbolize the new block. Nodes that discover the new hash code the quickest are rewarded with cryptocurrency, akin to Bitcoin or Ether.
Now, blockchain nodes, which energy nonfungible tokens, media and different widespread functions, more and more use these chips, driving chip consumption points alongside demand from AI and deep studying.
“Cryptocurrency mining is based on proof of work that is high computation intense and power-hungry, but mining chip design is much less complex compared to the microprocessor MPU, GPU or [Associative Processing Unit],” stated Samuel Wang, analysis vp at Gartner.
The wafer demand for cryptocurrency application-specific built-in circuit chips is “totally manageable,” at lower than 30,000 300-millimeter wafers monthly globally, Wang stated. It’s one thing that was arguably “never in shortage.”
Likewise, on the macro stage, Wang stated that blockchain operations are usually segregated from mainstream IT.
“On blockchain, there are companies specializing in the operation of data centers for handling blockchain for customers,” Wang stated. Because each PCs and knowledge facilities can function blockchain, when chip shortages hit each, the blockchain enterprise slows down.
“But I doubt blockchain was the cause of the shortage for PCs or data centers,” Wang stated.
Blockchain might be designed by one of two algorithms: proof of work (POW), which calls for energy, or proof of stake (POS), which has a decrease energy requirement.
“POS is a newer method for blockchain as it is faster, less expensive and more energy-efficient than the traditional POW used by cryptocurrency,” Wang stated. “My judgement is that more blockchains are moving toward POS; therefore, power consumption and chip demand can be minimized.”
