Today, we’re proud to announce the release of the open-source, Polygon ID Identity Infrastructure! 🎉 This is the first decentralized identity platform using zero-knowledge (ZK) to issue credentials on-chain, making it secure and privacy-preserving to power identity on web3. 🧵

The @0xPolygon #zkEVM testnet was designed from the engine (zkProver). We created public.zkevm-test.net back in October once we had complete, auditable ZK proofs with EVM-equivalence. After 50k+ proofs, we know how we can scale #Ethereum. Working to speed it up.

Excited to see @billions_ntwk live on @KaitoAI. Proof-of-human meets proof-of-attention.

The new public.zkevm-test.net is out! - ZK Proof recursion enabled - L2 Batch size increased from 4 to 10M gas - Proof time reduced from 10 to 4 min - L1 verification with 350K gas This adds more efficiency and ability to manage the tradeoff between finality time and tx cost.

We are very excited about the progress of EVM-equivalence in @0xPolygon #zkEVM! Currently, we are passing 99.5% of Ethereum test vectors that apply to our type-3 implementation (9.650+ tests passed): github.com/0xPolygonHermez 1/n

We still have a lot to build — but I wish more people could see just how strong this team is and how hard everyone’s been working behind the scenes. Proud of the progress. More to come. @billions_ntwk

AI is eating the internet. At @billions_ntwk we’re building the missing trust layer - one that respects privacy and enables secure, human-to-AI relationships at scale.

On @billions_ntwk , your info stays on your wallet. When an app needs to know something about you, it asks — and you choose what to share. You prove it’s true with zero-knowledge, but no data is sent. Simple, private, in your control.

A real-world use case of @billions_ntwk wallet — and one we’ll be repeating with other teams very soon. That airdrop? It was for humans only. The best part? The success led to a new partnership with our friends at @lagrangedev.

With Billions, projects achieve better ROI on token allocation. Lagrange used our Proof of Humanity for a secure, privacy-first ZK airdrop 🧵👇

Our wallet is not just for storing your identity. @billions_ntwk lets you prove it — privately, with ZK. To websites, decentralized apps, and even IRL. One verification. Infinite destinations. EVM-ready. More chains next. This is how identity scales.
