Open Labels Initiative

A standardized framework and data model for EVM address labeling

[Open Labels Initiative @open_labels]

OLI labels are now available as public BigQuery tables!

~170M contract labels are queryable directly in BigQuery, including decoded labels and raw attestations.

Built for analysts, researchers, and builders working with open onchain labels.

as always: labels are "just" the raw label pool - a collection of all submitted labels/attestations. This also means that there might be duplicated labels.

In order to get to "trusted" labels, you should define your own trust list - which attesters (i.e. growthepie, Sourcify, etc) do you trust?

@sampotter___ give it a go and let us know if any questions pop up 😎

The explorer now uses @open_labels for contract and account names.

How does trust work in OLI?

Anyone can submit labels to the Label Pool, so trust is critical. We've built a transitive trust system that assigns a confidence score to each label based on a trust list and how trust propagates through the network.

We got a new banger workshop, this time by the one and only @LehmannLorenz !

26. Feb at 2pm CET
A hands-on workshop on how to access high quality labels!

This is for you if:

​* You are using or planning to use the OLI Label Pool and want more control over which labels you trust

* You want to understand how trust lists work and how to filter out low-quality or untrusted labels

* You want to assign a trust score to each label from the OLI Label Pool

​What you can expect:

​We will introduce the concept of trust lists and why they are essential for working with open, community-sourced labels.

​You will learn how to create and manage your own trust list to filter the OLI Label Pool

​We will use the OLI pip package to build a simple trust setup, fetch labels and apply filtering in practice

​By the end, you will have a working trust-based labeling flow you can integrate into your own analytics, dashboards or applications.

[Open Labels Initiative @open_labels]

Oli Trust workshop is tommorrow!

Come by to learn how to best get the highest quality labels in oli's Label Pool.

And aditionally how to rate and add your own trustlist to the OLI so that everyone else can make better decisions what label to trust.

See you there!

@growthepie_eth has added detailed tracking for @Starknet apps — now you can see real user activity data, spot which dApps are actually growing, and follow where people are spending time and transactions on the chain.

> For everyday users: It's a quick way to discover the hottest or fastest-rising projects on Starknet without guessing.

> For builders and devs: Tag/label your smart contracts properly (use tools like @open_labels), and your app's metrics will show up accurately in their dashboard.

This plugs you straight into transparent, on-chain performance visibility that helps everyone see real traction.

Simple, open data like this makes the ecosystem way easier to explore, understand and grow.

Big Ups to the @growthepie_eth team for shipping this!

The power of an open registry for blockchain labels!

[Lorenz Lehmann @LehmannLorenz]

First time seeing @blockscout showing labels sourced from @open_labels label pool and I love it!

Blockchain labels should be a public good. Attest once, automatically integrate everywhere. This is how we move toward a truly transparent and decentralised future.

Reminder: Tomorrow is the day
​The workshop is tomorrow, January 29, 2026 at 2:00 PM CET.

​We’ll go from prepping our CSV → Submiting OLI labels easily through hardhat → a minimal UI and example scripts to read them with the SDK.

​Will try to make it hands-on by creating a few tasks and hints along the way.

​Then cap it with how beautifully the onchain tools on our web page can make your life easier with all the tags and its quick fixes.

​Prepare your dummy private keys and get a OLI API Key already to be ahead of the game tom'!

Hey everyone! We got a special event on our January monthly call on the 15th next week.

We are showcasing a few of the new OLI toolsets and playing around with some labels together in this hands-on workshop.

This will be a great time to bring your questions and get on track with OLI and how to use it.

[growthepie 🥧📏 @growthepie_eth]

We are seeing increased registrations for the Ethereum Attestation Service on OP Mainnet

Would love to see more contracts tagged @eas_eth @brycepatrick @open_labels

[matze | growthepie 🥧 @web3_data]

Only 4 days left to vote in @OctantApp epoch 10 👀

If you have GLM staked and want to support Ethereum projects, make your way to the Octant app and donate to your favorite projects.

Octant matches the donations with 268 ETH (yes, almost $1M).

@growthepie_eth is also participating in this round and is grateful for every donor 🙏

Also, if you don't have any GLM staked yet, go get yourself some GLM and stake it so that you can partake in future rounds.

This is how you can help shape Ethereum.
You can just do things 🫡

Frontier phase on @megaeth is heating up.

App developers are now actively deploying and tagging their contracts with @open_labels.

Integration is a smart move. It gives developers free, transparent metrics on @growthepie_eth to track their early traction.

But more importantly, it instantly makes their new applications discoverable to the first wave of users on the fastest chain.

Flywheel is starting to spin.
