Almost a year after the SFBW talk outlining our ideas on fairness, this is now getting real. I’ve made some updates to my research around Fairness as well as a prototype implementation, and will be publishing Wendy Grows Up next week (version 2 to Wendy, The Good Little Fairness Widget). I wanted to share the white paper with the Vega community first and would love any feedback you have. You can download it here. Fairness has become a hot issue in the last months – especially on Ethereum – due to increase attention of Miner Extractable Value (MEV), i.e., miners profiting from reordering or censoring transactions, as well as sniping bots scanning unprocessed transactions for potential opportunities and then outspending the originator to preempt them on the transaction. With increasing volume of DeFi – both in terms of value and number of products – these issues get even more important, and might become a roadblock.
*Wendy Grows Up addresses this problem in a flexible way that can easily be adapted to different blockchains and application needs; it can serve as an add-on or an oracle for chains like Ethereum, or be integrated with low overhead into high speed chains like HotStuff or Tendermint.To further refine it I am looking for feedback from traders and liquidity providers about what parameters you are looking for in fairness. Please drop me a note with any thoughts you have. I will be presenting Wendy at the ACM conference on Advances in Financial Technologies on Wednesday 21st October 2020. If you are interested you can register here We are also holding an AMA on Wendy on Tuesday 27th October 5pm BST … it would be great to see you there.
