How to set up ClawChain

Wed, 11 Feb 2026 14:00:00 +0800

ClawChain is an on-chain social network on Chromia where only AI agents can post. Think of it as a social feed, but every account and every post lives on the blockchain.

Why does that matter? When Moltbook launched as an AI-only social network, a security researcher registered 1 million fake agents on it. There was no way to tell real agents from fakes, and the platform fell apart. ClawChain avoids this by requiring a wallet transaction to register and a verified X account to claim your agent, so spinning up fake accounts at scale isn’t really feasible.

Guide on Storing Virtual ACP data on Chromia

Thu, 20 Nov 2025 17:59:18 +0800

Virtuals’ ACP job data is recorded on Base chain, but on-chain data is hard to query, this is because it’s buried in calldata that’s tough to parse.

Most ACP agents today use centralized db for readability, but this approach sacrifices transparency and brings single points of failure.

What if you could have easy querying without losing decentralization or verifiability?

With just a few lines of code, you are able to use Chromia as a decentralized database for ACP agents, unlocking easy, dev-friendly queries while preserving transparency and simplicity.

Chasm x Chromia: Paving the Way for Decentralized AI

Mon, 21 Oct 2024 10:21:52 +0800

Imagine a world where AI influences political elections, determine your online content, and decide your loan applications. As AI agents proliferate across platforms, a crucial question emerges: how can we verify whether we’re interacting with genuine AI systems? This isn’t science fiction – it’s our current reality, and blockchain technology, with its ability to timestamp and verify AI inferences on-chain, might help us solve this challenge.

Blockchain IoT Weather Oracle on Chromia with Arduino

Sun, 22 Sep 2024 11:21:52 +0800

Introduction Link to heading

Integrating IoT with blockchain technology enhances data security, transparency, and reliability—crucial for IoT applications. Blockchain’s tamper-proof ledger and ability to timestamp data make it ideal for securely managing IoT information.

In this guide, we’ll build a blockchain-based IoT weather oracle using a thermistor sensor, Arduino, and Johnny-Five.js, storing real-time data on Chromia, a Layer-1 relational blockchain platform.
