🚀 Big news for the @arbitrum ecosystem! Introducing arbos-foundry – a fork of Foundry that brings native support for testing Stylus programs. Developed by iosiro's @_dotvader for the Stylus Sprint, it brings the dev experience you love to the Stylus world.

@iosiro_security @arbitrum Shipping arbos-foundry was rewarding and challenging. Forking Foundry to bring native Stylus testing wasn’t trivial, but unlocking fast, local WASM testing made it absolutely worth it. Thanks to @arbitrum and the Foundry team - excited to see what developers build with this 🚀

Arbitrum is about to level up like no other EVM chain. 17 teams have just secured 5M ARB to innovate with Rust on Arbitrum.

Our latest bug report to @optimismFND in their sequencer stack allowed censoring of over 1.3m accounts for an arbitrary period of time. Affected protocols included: @LayerZero_Labs @StargateFinance @HopProtocol @SynapseProtocol @AcrossProtocol + more. 👇 iosiro.com/blog/optimism-…

@gakonst To add using Postgres/BigQuery for the transactions, block headers, block bodies, and other less IOPS intensive tables might allow for faster syncs and reduce running costs. No need to replicate that data when scaling horizontally.

@gakonst In the Q&A you mentioned someone replaced the KV store with Postgres. There a link to the implementation? Not to use, but good reference to see what needs to be done to support an alternative DB.

gave a small introductory talk about Reth to All Core Devs this morning... excited for Cancun, Devnet 9 & Holesky and to collaborate with the broader community building on nodes!

@0xSalmanA @gakonst Can confirm. Started my sync using ZFS pool with two 2TB NVMe SSDs. Sync was taking a lot longer than expected. Reformatted to ext4 to complete sync, performed a backup to an external drive and reformatted to zfs. Had a few other hiccups so can't give good metrics to compare.

@gakonst Thanks. Yea, that make sense. I imagine sync would also be slower on ZFS. Looking froward to the RPC benchmarks

report from community member: reth archive on zfs *1.1tb* vs a little over 2tb on ext4 incredible compression ratio see commit charts below (10-20x worse i/o), still need to measure latencies/throughput on RPC we'll have scripts for people to reproduce soon

We reported an issue in the @nethermind client that could have led to a consensus failure w/ other Ethereum clients. Bounties were awarded by @ethdotorg and @GnosisDAO. Another big one for @pleasew8t! Details: iosiro.com/blog/nethermin…

We recently disclosed a high risk double-spend vulnerability in @AcrossProtocol's bridge relayer infrastructure. No user funds were at risk! The issue was fixed and awarded with a $90,000 🪲 bounty. Read all the juicy details here: iosiro.com/blog/high-risk…

@gakonst @sourdzl @sina_eth_ @a_kirillo @ttobbaybbob Could be a lot more efficient if clustering was added: github.com/blockchain-etl…

Protip to scan (& pay for) less data on Ethereum BigQuery (here ~4x) BQ tables are partitioned by timestamp -> you can avoid full table scans by filtering via timestamp vs block number h/t👑@sourdzl for the observation & @sina_eth_ @a_kirillo @ttobbaybbob for working on this

We helped @AshiqAmien disclose a critical bug in @88mphapp. At least $6.5m of funds could've been stolen by attackers. That's no longer possible. Funds were whitehacked from the contract and returned to users. Bug bounties work. Read the postmortem: medium.com/immunefi/88mph…

@iamdevloper Where does `console.log("no error yet (24))"` fit on the scale?

On a scale of 1 to `console.log('here')` debugging, how bad is your morning going?

@johncdalton @Sarah_Mulvx Also no unboxed deals

@Sarah_Mulvx I don't see any reviews?

@sudo_vii Not great, not terrible

Hey healthy people. I've been exercising daily for a while and am now at the fittest I've probably been in years... Is a 64 resting heart rate good or bad?

Results of some late night source code reading: helm.sh/blog/chartmuse… and helm.sh/blog/helm-secu… Awesome work by the @helmpack team, they made the disclosure process exciting and rewarding by responding to and fixing the issues in record time.
