    Sheel: So if I send $1,000 from the US to my cousin in India via stablecoins, what would she get in INR? Brian: She'd get ₹83,000 worth. And the best part — it's basically free. Sheel: Basically free, or free? Brian: Free. Stablecoins make remittance fees go to zero. Sheel:
    How can stablecoins reduce remittance fees to zero? makes no sense to me whatsoever. The bulk of remittances $ is migrant workers sending money to family, from US->Mexico, US->India, Gulf->India Stablecoins can make the money-movement leg much cheaper/near-zero but that isn't

    Just joined @eigencloud! Super stoked and looking forward to learning from, contributing to, and pushing forward with one of the top teams in the space. Let's BUIDL!

    Ethereum started with a mempool and flashbots removed it. Solana started with no mempool and jito added one.

    This past month I got the chance to participate in @wintermute_t x @encodeclub's MEV hackathon. @0xK1000 and I just submitted our project "MEV mitigation using modular DAG-based consensus protocols" (docs.google.com/presentation/d…). Would love some criticism/feedback!

    We wrote the first (?) btc lightclient on starknet at the starknet hackathon in Amsterdam. Check it out: github.com/samlaf/starkne… Thanks to @GuthL for the constant moral and technical support, and my awesome teammates @maxgillett github.com/tekkac and BrDu#1111

    Did I just read that Sui has a way to enforce NFT royalties onchain?
    IMO this is one of the best security features of Sui's native object ownership--classic wallet drainer attacks (e.g., giving a token/NFT approval to a smart contract that later gets hacked) are impossible by construction. If coins or NFT's are owned by address A, it is only

    For those having trouble understanding the connections between the different parts in @svlevine's (awesome) control as inference tutorial, I made this diagram synthesizing the major relationships.
    If you want to know how probabilistic inference can be tied to optimal control, I just put up a new tutorial on control as inference: arxiv.org/abs/1805.00909 This expands on the control as inference lecture in my class: rll.berkeley.edu/deeprlcourse/

    Really enjoying the Aptos guys coming out on twitter and sharing their views more. This guy is insta follow for me.
    Here's some of my takes, got to the party a bit late, opinions are my own.

    Check out our new work. Been thinking about "illuminating the dark forest" of Narwhal based chains for a while, and @0xtrojan_ the powerhouse was just the perfect fit for this task. Was a blast to work with him.
    1/ MEV 🤝 DAG: As a part of the @eigencloud research fellowship, I worked with @samlafer on analyzing the landscape of MEV on chains that use Narwhal DAG-based consensus mechanism ♾️🧵 Here is what we found 👇

    Themis (@_mahimna et al's) protocol achieves a precise notion of decentralized-FIFO ordering called batch-order-fairness (BOF) without sacrificing liveness, but requires n>4f. @0xK1000 and I tried to distill the paper, and stumbled upon interesting things!

    Replying to @0xmisaka
    It certainly has blocks. It's a DAG-based mempool, not unlike that of Avalanche, where every validator can "propose" blocks every round of the DAG, all of which get totally ordered by a consensus running on top of the DAG. See my recent thread:

    Saturday morning brain dump of web2 auth, smart contract wallets EIP-4337, zk auth, and eigenlayer AVS/operator registration. What we want is **fine-grained**, **programmable** authorization and authentication.

    Do you view PoW and PoS as sybil resistance mechanisms, or as economic incentive-alignment schemes? Or are those two sides of the same coin?
