The KelpDAO hack meant $292M lost because their verifier depended on a fixed set of RPC nodes. Attackers compromised those nodes and fed fake data. If they had randomized node resolution as a fallback, the attack model breaks.
Today I announce NRS: Node Resolution Service. A free service that gives you a working RPC endpoint for any blockchain in milliseconds.
Once your request hits, we pick a healthy node from a curated pool, and redirect you there. Every request goes to a different node i.e no single point of failure.
Live now with $ETH $BNB $POL $ARB $IGRA and testnets.
Open source, free, MIT licensed.

Toccata is arguably one of the biggest and most anticipated upgrades $KAS has shipped. Covenants ZK opcodes change what you can build on it.
I’m speaking at this Berlin Blockchain Week workshop, breaking down how they actually work and where the sharp edges are.
What do you most want covered? 👇

Native assets on $KAS would be quite cool. We just need to agree on a standard, similar to ERC20. Who’s down to buidl?

New version of t.me/Igra_watch_bot:
- /stats now returns actual liquidity and network information
- New /bridges command monitors inflows and outflows across all Hyperlane routes
- Backup RPC failover via nrs.pub by @asaefstroem
- Performance and stability fixes

The ZK SDK is reaching maturity. This short snippet demonstrates how easy it will be to verify a ZK proof on $KAS!

Check it out here: nrs.pub. No API keys, no accounts, no provider setup. Just use nrs.pub/1 for Ethereum, nrs.pub/56 for BSC, and so on.

So $ARB just froze 70M of the stolen $ETH. That is fine, but this should have been a decentralised vote via staked $ARB. Now, Arbitrum is simply a representative democracy, except without democracy.
The Arbitrum Security Council has taken emergency action to freeze the 30,766 ETH being held in the address on Arbitrum One that is connected to the KelpDAO exploit. The Security Council acted with input from law enforcement as to the exploiter’s identity, and, at all times, weighed its commitment to the security and integrity of the Arbitrum community without impacting any Arbitrum users or applications.
After significant technical diligence and deliberation, the Security Council identified and executed a technical approach to move funds to safety without affecting any other chain state or Arbitrum users.
As of April 20 11:26pm ET the funds have been successfully transferred to an intermediary frozen wallet. They are no longer accessible to the address that originally held the funds, and can only be moved by further action by Arbitrum governance, which will be coordinated with relevant parties.

This is why bare metal, will win.
🚨 BREAKING: Vercel has been breached. A threat actor has listed their customers' data, source code, databases, and keys up for sale.
Vercel has also publicly disclosed they've identified a security incident involving unauthorized access to their internal systems.

$KAS, what is your opinion on this? The coins are effectively already out of circulation.
Apr 15
Satoshi's coins should not be frozen.
Let them be quantum mined.
The network will adjust.
Proof of work.

Man it feels so good to be back working on $KAS, what a crazy alien technology. 🚀👽

Given the recent supply chain attacks, hacks and general uncertainty in cybersecurity space, I decided to publish my crate I’ve been using personally, ezpgp.
Ezpgp, is a rust PGP-based offline messaging system. Good for sharing credentials between each other and other sensitive data. Built to be as minimal as possible so that you can actually audit the code yourself.
Can be installed via: cargo install ezpgp with source code available at: github.com/saefstroem/ezpgp.
Crates: crates.io/crates/ezpgp/0.1.0
Stay safe! #Rust

Worried about quantum computers stealing your $BTC? Don’t be, just follow two rules:
1. Store on an address you’ve NEVER spent from
2. If you spend, immediately sweep everything left to a fresh address
Here’s the thing: quantum computers can only crack public keys. But your $BTC address isn’t your public key it’s a hashed version of it. Your actual key only gets revealed when you make a transaction.
So if you never spent from an address? Your public key is hidden. There’s nothing for a quantum computer to attack.
#Bitcoin security is easier than you think.

One nuance for the nerds:
The hash protecting your $BTC address isn’t fully quantum-proof either. Grover’s search could theoretically cut the security in half.
Sounds scary? It’s not. Half of 160-bit security is 80 bits. That’s still more combinations than atoms in a human body.
Don’t reuse addresses and sleep easy. #Bitcoin
