Onchain privacy isn’t solved with storytelling.
At @web3edubrasil Brazil 2026, @neylanxyz and I ran a workshop: Building Private On-Chain Transactions with Noir, Solidity & Barretenberg.

Commitments, Merkle Trees & Zero-Knowledge Proofs — all hands-on, everyone in the code. 🔐

[heronlancellot.eth @heronlancellot]

Hackathons aren’t coding marathons — and no one tells you that.

@mika_sza and I took that to the stage at @web3edubrasil Brazil 2026 @Oracle .

After 6 wins: code is just one part. What wins is strategy, narrative, the right team, and the right story for the right people. 🚀

Huge pleasure to be part of this! 🙏 Let's build private onchain apps with Noir, Solidity and Barretenberg — see you in São Paulo on June 27! 🚀

[Instituto Web3EduBrasil @web3edubrasil]

🚀 Pare de apenas estudar privacidade. Comece a construir aplicações privadas onchain.

Se você já iniciou no universo Web3, este é o seu próximo passo técnico.

No workshop Construindo Transações Privadas On-Chain com Noir, Solidity e Barretenberg, você vai aprofundar seu entendimento sobre privacidade e Zero-Knowledge Proofs aplicados à blockchain:

🔹 Fundamentos de commitments e Merkle Trees
🔹 Conceitos práticos de Zero-Knowledge Proofs (ZK)
🔹 Integração entre Noir, Solidity e Barretenberg

Tudo isso em uma experiência hands-on com o @wallabyxyz_ e @heronlancellot.
🧠 Ideal para desenvolvedores de nível intermediário e avançado
💻 Necessário levar notebook

📅 27 de junho
⏰ 13h às 15h

Be AWARE of this 'Fake Podcast' scam in crypto

This is the second time I've been a target (and they failed)

1) Big publication will email or reach out on Telegram to interview you in their podcast

2) They send you a fake "Streamyard" link (pay attention to it not being .com)

3) It prompts you to download their "Desktop version" (Streamyard is browser only)

This is malware. It will hijack your wallets, your Telegram, your entire computer.
