Wrote a short post on using Harberger Lease, an idea from @aja @ciamac @undefined and @danrobinson, for Execution Tickets/Auctions. It is an interesting way to prevent hold-out problems and increase allocative efficiency at an, in my opinion, slightly increased risk of more multi-block MEV. https://mirror.xyz/0x03c29504CEcCa30B93FF5774183a1358D41fbeB1/TO_fODV1R1QampX9FVGOYP6m9WZAKckFsZjaj1dizTI

thanks for having us on and the productive back and forth @hasu @joncharbonneau! staking economics is a super important topic and hopefully this convo helps to give more context on the intentions of our proposals and how we see things :)

We model an investor deciding how to stake its ETH with a simple linear programming problem. The model is simplified and not meant to be holistic. Rather, we want it to base the conversation around staking economics in addressable models and encourage others to iterate!

New post exploring the impact of issuance on Ethereum staking! A decentralized distribution of stake is important. Our analysis shows that stake distribution remains unaffected by the level of issuance.

Thanks for the suggestion, definitely something we will look into. Different but related. The authors of this paper use a sequential model to model the adverse selection costs of JIT LPs on passive LPs https://arxiv.org/abs/2311.18164

This paper shows the cost of permissionless liquidity provision in AMMs, check the full thread here 😀

The intuition is that as the arbitrage intensity per unit of liquidity decreases, more liquidity flows in, so the total amount of arbitrage may not decrease proportionally.

Finally, we show that clever AMM design may reduce the arbitrage intensity per unit of liquidity but that this does not lead to a proportional decrease in the total amount of arbitrage and, under some circumstances, even an increase.

Our main result is that the price of anarchy, defined over the liquidity provider performance, is O(N), meaning that the welfare loss to LPs scales linearly with the number of passive LPs

These two effects are not aligned because the marginal LP tries to get some of the fee revenue obtained in the AMM without this additional liquidity. This means that LPs deposit liquidity beyond the optimal point: where fee revenues equals adverse selection and opportunity costs

Passive LPs have two reasons to deposit liquidity. More liquidity induces more trading demand, and leads to a greater share of total fee revenue, since fee revenues are distributed proportional to the fraction of liquidity provided. The liquidity and competition effect

Excited to release a new paper with @davidecrapis! We present a game theoretic model of simultaneous liquidity provision by passive LPs. We show that competition between liquidity providers causes a loss in total LP welfare that grows linearly with the number of passive LPs.

Here is a new RIG Open Problem on the specification of a Multiplicity gadget in the context of Ethereum’s Gasper consensus. Good problem for a consensus researcher interested in censorship-resistance! https://efdn.notion.site/ROP-9-Multiplicity-gadgets-for-censorship-resistance-7def9d354f8a4ed5a0722f4eb04ca73b
