Classix

Classix is an open source development agency with skin in the game, building and maintaining critical infrastructure for Ethereum Classic.

[Classix @classix_dev]

What Classix shipped for #EthereumClassic in October:

• ETC’s full history back on Google BigQuery
• etchd, an OpenTimestamps calendar anchored to ETC
• Research on ETC held at exposed public keys
• New Nethermind ETC plugin and Besu for ETC releases

Building in public, every month.

@ClassicIsComing That there is no dev team helping advance the ecosystem. We're here. ☘️

[Classix @classix_dev]

We spent last week at #Devcon8, connecting with folks from across the #Ethereum and EVM spaces, and came home with plenty to talk about.

• 11 special ideas for ETC in 2027
• Our packed meetup, with 213 more on the waitlist
• Besu is set to run ETC without a fork, thanks to @diega's plugin work

And a whole lot more below.

Of course not. Just because one organization ceases operations doesn't mean a network will cease to exist. That would make the network a centralized failure.

There are greater times ahead and we plan on bringing our best to ETC - picking up where the Co-op left off!

@mitansh_j07 The Cooperative has been winding down for some time now. We're picking up where they left off. You can learn about who we are below!

Many thanks to @BobSummerwill for leading the Co-op through some of ETC’s toughest years, and to everyone else who worked there along the way. ETC is better because of you all.

And a special thanks to @BarrySilbert and @Grayscale: thank you for believing in Ethereum Classic enough to support the Co-op's stewardship of ETC from day one.

That support built a foundation the whole community still stands on.💚

[Classix @classix_dev]

For 9 years, @ETCCooperative showed up for Ethereum Classic: funding development, supporting builders, and holding the line when it wasn’t easy.

Thank you. Part of why ETC is still here is that work.

As one chapter ends, the next one begins, and we’re proud to help write it.

[ETC Cooperative @ETCCooperative]

ETC Cooperative has begun winding down its operations. Since 2017 we've supported Ethereum Classic through protocol, infrastructure, tooling, education and community funding. Thank you to everyone who built this with us.

That was 2020, when ~4 TH/s secured Ethereum Classic.

Today ETC ranges from ~205-230 TH/s.

Etchash on NiceHash: 66.5 GH/s, or ~0.03% of the current network hashrate.

You can’t rent your way to 51% anymore.

But we keep watching anyway. 🔍

[Classix @classix_dev]

In 2020, attackers rented hashpower on NiceHash for ~15 hours, privately mining over 4,000 blocks, paying about $192K to double-spend $5.6M.

Back then, no one was publicly watching for reorgs.

Now Triforce monitors ETC live, 24/7, and logs every reorg the moment it happens. 🔍

[Classic Kevin Lord @Classic_Kevin_]

Wrote a beginner-friendly guide to running your first core-geth node with Docker.🐳

Short of downloading the binary, this is the easiest way to run an ETC node. You literally just run one command.

I’m not a developer, so if I can do it, you can too.🧑🏻‍💻

Since March 2021, the #EthereumClassic community has met for 62 Community Calls.

A few worth your time:
• #16: ETC’s principles, with Donald McIntyre
• #37: the Spiral upgrade
• #41: should ETC adopt EIP-1559?
• #57: 10 years of Classic
• #62: “Bunker Mode”, quantum, AI and ETC’s signatures

Which one should we clip first?

[Classix @classix_dev]

For exchanges, pools and service providers that handle Ethereum Classic:

When it comes to block reorgs, we stay proactive, monitoring the network 24/7 from 11 Triforce nodes across four clients – logging every one the instant it occurs.

We’ve counted 135 since late September, none deeper than 2 blocks, which is normal in proof-of-work.

If anything deeper shows up, we’re the first to see it. 🔍

ETC hasn’t had a reported 51% attack since August 2020, when only about 4 TH/s secured the network. Hashrate recently peaked at 235.98 TH/s, the highest since late December 2025.

[Classix @classix_dev]

Running an #EthereumClassic node shouldn’t depend on who set it up.

Our Nix builds of all four clients and NixOS configs for mainnet and Mordor are on GitHub, along with tooling for chain replays and devnets.

No single point of failure. Including us.

@web3privacy @robdotrego Thank you all for putting together such an amazing event. A major highlight of our week.

Looking forward to Cypherpunk Congress #4!

[Classix @classix_dev]

@changerofficial @eth_classic @BobSummerwill 🇮🇳 💚

[Classix @classix_dev]

What a week at #Devcon8 🇮🇳

New faces, familiar ones, and talks from some genuinely inspiring people.

Many thanks to @EFDevcon and @web3privacy for putting together these great events, and a big thank you to everyone who came to our Ethereum Classic meetup.

You made the trip extra special.💚

We'll be sharing some videos and blog posts from our week here, so keep an eye out.👀

[Classix @classix_dev]

Such a great night in Mumbai. Many thanks to @BobSummerwill, and everyone else who came out to talk Ethereum Classic with us.🍀

Didn’t get a chance to chat?
Come find us at #Devcon8 this week!

Every item, with links to the work behind it, is in the October Activity Report 👀

Work goes back to the day Classix started.

[Classix @classix_dev]

Project Triforce, the node grid behind #EthereumClassic public RPC:

• 11 nodes, 4 clients
• 3 providers, 3 regions, no two nodes in the same building
• Every node pins the other 10 over a private mesh
• Watches reorgs, the mempool and every peer it can see
• Two archive nodes feed ETC’s full history into Google BigQuery

Watch it live 🔍 https://t.co/TVawTutDq9

[Classix @classix_dev]

All the work we do for ETC can be tracked since our inception.

See for yourself 🔍

[ETCGrantsDao @ETCGrantsDao]

The chain has always recorded the exposure.

Most chains just prefer not to measure it. #ETC

[Classix @classix_dev]

@ETCGrantsDao We keep track of everything we do, going back to our inception! 👀 https://t.co/GdvwVlbX0S
