Zvonimir enhanced the node score calculation in the OriginTrail/dkg-evm-module by implementing a new weighting formula within the RandomSampling smart contract. Using Solidity, he adjusted the influence of nodeAskFactor18 and nodePublishingFactor18, dividing the former by ten and multiplying the latter by fifteen before summing with nodeStakeFactor18. This approach aimed to better reflect node capability and participation, thereby improving the reliability of node selection and aligning rewards more closely with actual contributions. The work demonstrated a focused application of smart contract development skills, addressing incentive balance and selection accuracy within a complex decentralized system over a one-month period.
