Announcing the 2025 Columbia Cryptoeconomics (CCE) Workshop, December 10+11 at @Columbia (link in replies). Confirmed speakers include @BenBerg07141321 @liobaheimbach @ks_kulk @AndrewLewisPye @mikeneuder @noamnisan @malleshpai @Tim_Roughgarden Maria Inês Silva @ssrivatsan97

Timeboost is now live on Arbitrum One and Nova. This new transaction ordering policy allows users to bid for express lane access, which provides faster transaction inclusion while maintaining Arbitrum a private mempool. Why it matters. 👇

In a joint work with @BenBerg07141321 @EdFelten, Benny Sudakov, we study censorship attack during a challenge protocol of an optimistic rollup. Block proposers, who control transaction inclusion on base layer, can be bribed by an adversary to exclude honest party's transactions.

Today, BoLD delivers permissionless validation, making the Arbitrum ecosystem more secure and more decentralized than ever. Anyone can defend Arbitrum. Stage 2 soon.

We looked into the option of selling multiple TimeBoost licenses. While having multiple arbitrageurs with time advantage has obvious advantages and disadvantages, there is a considerable probability one monopolist will buy all of them, given extra value from owning all licenses

@OffchainLabs is #hiring an EA to work with our CEO, @sgoldfed, on cross-organizational initiatives! This isn’t just another #job; it’s your chance to shape the future of the firm shaping the future of #Web3!🚀 Know anyone in #NYC area who'd be a fit? https://t.co/RJXK8AWcFn

In a new paper ( https://t.co/yqkQZ4JtBl) with Minghao Pan and Christoph Schlegel, we look into Sybil(Sibyl)-proof mechanisms. We show that the only non-wasteful, incentive compatible and Sybil-proof mechanism is a second price auction. A🧵:

Since fraud proof security is in the news-with some questioning whether it even matters if a fraud proof system is secure-let’s review Arbitrum’s approach to protecting user funds with fraud proofs. This is my view but I think it’s widely held in the community. 🧵

Arbitrum has just processed over 1 BILLION transactions across One and Nova. We've come so far as an ecosystem, and yet our growth has only just begun. Thank you for building with us. 🤝💙

Proud of the whole @OffchainLabs team for making this happen-especially our research team for the heavy lifting to make sure this groundbreaking protocol is secure by design, and proven secure. Want a technical deep dive?

We’re thrilled to see Arbitrum BOLD live in testnet! Since Arbitrum’s inception, Offchain Labs’ focus has been aligning with Ethereum’s vision of decentralized rollups. The BOLD public testnet is the next step in its journey to becoming a Stage 2 rollup.

Just to highlight how much of a laughing stock the BBC is now, an Israeli satirical programme made fun of them and it’s pretty spot on.

Something is seriously wrong in our society if people feel free removing posters of kidnapped kids

1. בימים האחרונים, הנפש סוערת. ככל שעובר הזמן, העדויות והתמונות נעשות קשות יותר והכאב הופך להיות בלתי נסבל. אל מול התמונות המחרידות של ילדות וזקנים, תינוקות ונשים, מתבוססים בדם נקי מכל חטא – חיפשתי מילים, נחמה וכיוון. חיפשתי אותם עבור אלו שאיבדו את הכול, >>>
