It is a small coup that fairness is so associated with "fair ordering" / time based ordering There is no single notion of "fair." These protocols privilege a different set of actors and MEV extraction is a different "game" to play on them Disclaimer: personal views

@monad_alexander rootkid ✌️ unsigned_algorithms I would rather buy on an open-source marketplace than on any closed source one. Reason one I can verify what is going to happen, reason two I know the dApp is contributing to the ecosystem with the open-source code (especially important in the early days now).

In reality SPOs have always full control over transaction ordering, not exposing the API of the tx management is just wishful thinking, in reality you can always patch the node, hook up debugger to it or find some other way, to order, prioritize, or exclude transactions in block.

There's no such thing as a "closed-source decentralised exchange". Interested to hear your thoughts - am I missing something? Here's mine: hrpr.uk/2022/02/10/clo… #Cardano #ADA

I'm proud to formally introduce TxPipe, a small team committed to contribute to the #CardanoCommunity by building open source tools and infrastructure for developers. The new home for Oura, Scrolls, Pallas and many more to come🤞 txpipe.io

Whitehat satya0x reported a critical vulnerability in wormholecrypto on Feb 24 via Immunefi. The bug was quickly patched, no user funds were affected, and satya0x received a $10 million payout from Wormhole, the largest bounty payout on record. medium.com/immunefi/wormh…

Join me and Canonical next week to talk about smart contract and Cardano security, as well as topics such as MEV, the mempool, batchers, bug bounty, opensource, etc...

Oura is an #OpenSource project built with the effort of several contributors from the #CardanoCommunity. This release includes contributions from: skb, 4TT1L4 (github), Roberto C. Morano, Harper, Lucas, Santiago Carmuega

Dear #Cardano community! We've submitted several proposals for Project Catalyst Fund 10! 🥳 Our mission is to usher Cardano into the mainstream by offering the most advanced dApp developer platform and empower YOU the community to build better, faster, and easier. #Fund10 🧵👇

Maestro placed 1st in the Battle of the Builders #cardanosummit2023 The competition was fierce. There were so many brilliant, innovative projects, and we were simply happy to take part. We are truly humbled by this experience and want to thank our fellow competitors.

👀 Early support for Conway primitives in Pallas: github.com/txpipe/pallas/… A big step in the path for #Rust tooling and libraries that integrate with #Cardano governance actions. ♥️ contributors: Harper, lisicky (github)
