Blockchain Coding Contest Offers $100K Prize


- Advertisment -

A Blockchain coding competition supported by Amazon Web Services (AWS) is offering a $100,000 prize to anyone who can solve a problem and provide the fastest speed improvement to it, according to a report

The problem is as follows: 

“Given 1024-bit input x, compute the verifiable delay function ‘h=x^(2^t) mod N’ as fast as possible.



The contest wants to “change the face of Blockchain,” and it was launched by the VDF Alliance. The goal of the contest is to solve how to calculate the verifiable delay function (VDF) in the shortest time.

Justin Drake, a researcher with the Ethereum Foundation, explained 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. It’s trustless. For the first time, it adds this notion of time with which you can build all these cool things.”

When he says cool things, he’s referring to something called “unbiased proof of randomness,” which would mean truly random number generators on blockchains. Right now, those don’t exist. There are pseudo-random number generators and those can be exploited. True randomness wouldn’t allow a bad actor to guess the number. 

The tech would aid blockchain like ethereum to less energy-intensive.

“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 in partnership with the Ethereum Foundation, as well as other alliance members, the Interchain Foundation, Protocol Labs, Supranational, Synopsys, and Xilinx, as well as AWS.
