Today we're releasing Plasma, a reference implementation of a sandwich-resistant AMM.
Plasma is an application-layer solution to sandwich attacks, based on the design published on @UmbraResearch. Plasma is audited and source-available to help advance the development of more robust DEX architectures.
FUTARCHY AS TRUSTLESS JOINT OWNERSHIP
In this piece, @dj_d_sol explores futarchic governance as a market-based alternative to the flawed crypto governance we see today.
A SANDWICH-RESISTANT AMM
In this post, @jarxiao, @FrankieIsLost, @0xShitTrader, and @danrobinson introduce an AMM design that protects swappers from frontrunning attacks. This is an application-layer mitigation to atomic sandwich attacks.

TOWARD MULTIDIMENSIONAL SOLANA FEES
In this piece, @theo_diamandis, @tarunchitra, and @0xShitTrader explore how multidimensional fee markets can elicit demand signals from the market, and how multidimensional fees lead to better pricing, blockspace utilization, and UX on Solana.

SOLANA FEES, PART 1
In this series, we explore Solana's fee mechanism, a formalism for analyzing fee mechanisms under Solana's constraints, and some proposals for the system.
This first part by @0xShitTrader describes Solana's current fee mechanism and some of its effects.

ETHEREUM'S SUPPLY CHAIN, PART 2
In part 2 of this series, @0xemperor explores proposals for enshrining PBS.
We start by examining the reasons to enshrine, then move on to design goals, the proposals themselves, and other dependencies that implementations must be aware of.

SHARED VALIDITY SEQUENCING
In this piece, @pumatheuma, @0xShitTrader, and @jtguibas describe Shared Validity Sequencing, a shared sequencer architecture for optimistic rollups that enables atomic interoperability.
MEV ON SOLANA
In this piece, @0xShitTrader and @0xEdgar dive into the current state of MEV on Solana, how it will evolve, and its effects on the Solana network.
They also pose some open questions about the future of MEV on Solana.

INTRODUCING UMBRA RESEARCH
Umbra Research is exploring novel ideas in blockchain research.
Our first piece is on the lifecycle of a Solana transaction.
In this piece, @0xShitTrader and @buffalu__ dive into how the Solana runtime processes transactions, with an emphasis on transaction execution and ordering.
The goal of this piece is to set the stage for discussing MEV on Solana.
