Yesterday, we celebrated that it was exactly 10 years ago since we did the first @cphethereum meetup. I can't believe that we're still going after that long. It feels surreal how quickly those 10 years have passed. I've had so many crazy, amazing and unique experiences…

I was pretty pissed at the @mintlify team when they broke compatibility with languages in their syntax highlighter, without warning. But I have to hand it to them; since then, they've been shipping cool features non-stop, and the highlighter was fixed pretty quickly, too.
Ethereum has nearly made it to Year 10 because of unsung heroes behind the scenes keeping things together. We never forget where we came from thanks to people like @peter_szilagyi. A great reminder to always stay grounded, appreciate the origins of work & how it shaped the future

🔥 We’re working 16-hour days, every single day, to fight this battle in court. The trial is almost over — but I’m still facing massive legal bills. 💸 The costs are overwhelming, and donations are the only thing keeping us afloat. 🙏 I know we’ve raised a lot already, and no…
In 2015, when I first started building Etherscan as a solo founder, I would at times get "stuck" (no AI helpers back then!). One particular tricky area was the "internal txns". I remember reaching out to Peter late at night on Gitter —he was very helpful and kind.. he replied,…

Roman is one of the biggest contributors to Ethereum out there. Before Tornado Cash, he was critical for early ETH scaling via POA Network & xDAI and after that was critical to Blockscout, the first useable open-source block explorer. He is an Ethereum hero.
In NYC subway after long hours of work. Sleep deprived as hell. Trials are brutal.
You either get why the fight for Tornado Cash is existential for crypto, or you don't get crypto.
Can confirm this works and is as easy as it sounds.
Prevent a hack in 6 simple steps. (Here's how each step works):
huge news for the contract verification ecosystem. please consider using sourcify so that your contract source code can automatically be picked up by tooling (wallets, debuggers, etc) and other explorers (@blockscout, @routescan_io) via @verifalliance
We just launched a brand new Verification UI! With Sourcify APIv2, it makes verification smoother than ever: ✅ Clear error messages ✅ Onchain vs recompiled diffs ✅ One-click GitHub issue reporting when it fails ✅ Etherscan import ✅ Solidity & Vyper Let’s break it down 👇
Ameen is Ethereum. We are Ameen.
what is Ethereum? to witness the trials of zk pioneers to see defi take DC by storm to watch ETH catch a bid to create governments build on L2s to help unbank your mom to future proof democracy to upgrade citizenship with zkIDs globally *we* are Ethereum
What the ever-living fuck. DoJ/FBI/SDNY/IRS-CI is trying to imprison Roman Storm—an American software developer—for decades because North Korea Gov used his software. And they introduced evidence supposedly tying their witness—a scam victim—to his Tornado Cash software... ⤵️
This!
Anyone saying that end-users won't run their own infra. If they don't run their own infrastructure then they'll never actually benefit from any of the tech we built. They'll just trust a different third party! We better make certain that they run it!
It’s time to prevent hacks *before* they happen. The V1 of the Credible Layer is here. Beta testing starts now. We've been working on this for a long time now, and we are very optimistic about the impact it can have. Here's how it works. The Credible Layer has four…
If I'm not mistaken these are the first 40 million gas limit @ethereum block. Let's scale!
🚨 $44 Million Lost in CoinDCX Hack 🚨 Another reminder that not your keys = not your crypto. Centralized exchanges are convenient—but they come with risks. Just ask the users affected by the recent CoinDCX breach. Choose Self Custody, Choose AirGap!
North star should always be to do what is right and fair, even if not everyone is happy about it. Appeasement breeds resentment and good people will leave. If you want to build a community that cares -- always do what is right.
As an industry, we are not taking private key safety seriously. We aren’t taking wallet hygiene seriously. And we are constantly getting hacked because of it. “Oh verifying calldata is too hard” “It was just easier to put my private key in a .env” Step your shit up.
Hi everyone, At @CoinDCX, we have always believed in being transparent with our community, hence I am sharing this with you directly. Today, one of our internal operational accounts - used only for liquidity provisioning on a partner exchange - was compromised due to a…
