AWS Backs $100,000 Competition to 'Change the Face of Blockchain'

The highly technical conundrum has been posed to coders in a competition supported by Amazon Web Services that aims to "Change the face of blockchain," as well as how hardware is designed and made.

Launched by the VDF Alliance, the competition aims to solve how to calculate something called the verifiable delay function in the shortest time.

In its announcement, AWS paraphrases Justin Drake, a researcher with the Ethereum Foundation, explaining that "VDFs are a low-level building block in cryptography, barely more than a year old. It's the"V" or 'verifiable' in VDF that makes the approach so unique.

Included in the "Cool things" promised by VDF tech is "Unbiased proof of randomness." Effectively, it could enable trustless, truly random number generators on blockchains.

If the tech can be advanced sufficiently it could help to move blockchain such as ethereum from the energy-intensive and hence costly proof-of-work algorithm to one called proof-of-stake.

"The Ethereum ecosystem alone currently uses on the order of 850 megawatts to extend blocks. That's about $460 million in running costs per year," said Tim Boeckmann, senior startup business development manager for AWS in the U.K. "With VDFs in Ethereum, there is an opportunity to bring down that cost to less than $0.13 million for the 0.25 megawatts of energy to power the hardware random beacons."

The competition is being held in partnership with the Ethereum Foundation, as well as other alliance members, the Interchain Foundation, Protocol Labs, Supranational, Synopsys, and Xilinx, which are sponsoring the event "With support from AWS.".

As reported by CoinDesk previously, the Ethereum Foundation is already working on the VDF problem, revealing in February that it was considering spending $15 million in the search for true randomness.

VDFs are envisioned for use in ethereum's much-anticipated proof-of-stake system called Serenity, to which the ethereum network will migrate in the next few years.

The first round of the competition will run till the end of September, and will award prize money to the fastest design that solves the problem at the top of this article.
