🚀 Introducing Ethereum Comments Protocol (ECP)

ECP lets you post, reply, and react directly onchain—whenever you swap, send, mint, or play. No profiles, sub-cent gas fees, fully composable.

Try it in Interface today, the first app to integrate ECP, live on Base.

Building ethcomments.xyz 

built on farcaster: @larrybot, @qdau, @frames, @framesfun, /open-frames, farcasterchannels.com, farcaster.id, @mod, @search, @discove

3️⃣ Neutral & Open Source 100% open source, MIT licensed, immutable contracts. No privileged apps, no proprietary barriers. Infrastructure, not a walled garden.

(4/7)

2️⃣ Composable & Programmable ECP uses hooks—smart contracts that let communities and creators gate who can post, charge fees, reward curators & creators, launch tokens and build entirely new social experiences.

1️⃣ Interoperability & Permanence Your comments become a permanent, open record on Ethereum—fully accessible by any app. No more silos or lock-ins.

Your thing sounds really really really really cool. I hope you win, I hope it wins. 🙏

decentralized, community-owned, platform-agnostic protocol akin to DNS/ENS except for tags & tagging.

@ets, swaylocks.com & /tagcaster (eventually)

Congrats on this. It looks really cool.  I definitely admire any effort at creating an eth primitive.  

If I get some time I’m gonna see if it can integrate it in an app with @ets   I’m thinking a comment with hashtags in it is automatically indexed by ets.

Ok, but perhaps a v2 could have an option to choose between different types of storage (onchain, IPFS, arweave etc.)?

Btw, another question: can community choose their own mods? E.g. a community issues a modNFT and anyone who holds that NFT can moderate that community's channel? Is that possible in v1 rn?

we did consider it, and here‘s why we chose to put it all onchain

1. gas fees are sub 1 cent on L2 today, and will only get cheaper
2. it‘s much simpler for developers to integrate
3. hooks are more powerful as a result of being able to do things based on onchain content

that being said, our demo media upload uses pinata + ipfs for bigger files

Congrats! 🎉

Did you consider storing text on Arweave or IPFS instead (in JSON format). And then store only the hash/id on the blockchain? 

It would save a ton of gas fees, because the longer the text is, the more it costs if it's stored directly onchain.

This is awesome! Congrats on the launch David

Love this. You’ll like RARA, the social curation protocol, I built in 2022.
