Address Blockchain’s Biggest Problem with Supercomputing


Producing digital coins is not environmentally friendly, to say the least. Bitcoin mining – one of the best-known implementations of blockchain – consumes around 110 Terawatt Hours per year, which is more than the annual consumption of countries such as Sweden or Argentina.

The project involves running open-source simulations to study how the speed of transactions on the blockchain could be increased using various techniques, such as sharding.

Sharding implies splitting a blockchain network into smaller partitions called ‘shards’ that work in parallel to increase its transactional throughput. In other words, it’s like spreading out the workload of a network to allow more transactions to be processed, a technique similar to that used in supercomputing.

In the world of high-performance computers, ways to parallelize computation have been developed for decades to increase scalability. This point is where lessons learned from supercomputing come in handy.

“A blockchain like Ethereum is something like a global state machine, or in less technical words, a global computer. This global computer has been running for over five years on a single core, more specifically a single chain,” Bautista tells ZDNet.

“The efforts of the Ethereum community are focused on making this global computer into a multi-core computer, more specifically a multi-chain computer. The objective is to effectively parallelize computation into multiple computing cores called ‘shards’ – hence the name of this technology.”
