* [  2026-07-14 · Oskar Introducing EthSystems EthSystems builds confidential systems for institutional Ethereum, carrying forward the IPTF work as an independent company focused on privacy, protocol design, and commercial execution. ](/blog/introducing-ethsystems/)
* [  2026-06-11 · Yanis Exploring Hardened Shielded Pools Extending a working shielded pool with epoch nullifiers and PIR, and why private selection is the harder problem left for private payments at scale. ](/blog/exploring-hardened-shielded-pools/)
* [  2026-05-29 · Aaryamann Resilient Civic Participation Petitions on Ethereum where the signer list never exists and the outcome stays verifiable from chain state alone. ](/blog/resilient-civic-participation/)
* [  2026-05-14 · Aaryamann Resilient Disbursement Rails Aid payments on Ethereum that protect recipients even when local partners are compromised, or when recipients cash out into local currency. ](/blog/resilient-disbursement-rails/)
* [  2026-04-22 · Aaryamann, Oskar Resilient Plural Identity Designing identity on Ethereum that survives issuer failure: plural attestation sources, vOPRF sybil resistance, and an on-chain trust anchor that no single party can revoke. ](/blog/resilient-plural-identity/)
* [  2026-03-18 · Oskar DIY Validium: Private Logic on Public Rails A validium PoC where the business logic is ordinary Rust, proved in zero knowledge and verified on Ethereum. ](/blog/diy-validium-private-logic-on-public-rails/)
* [  2026-03-13 · Yanis Private Crosschain Atomic Swaps (Part 2 of 2) How a Trusted Execution Environment (TEE) can coordinate private crosschain atomic swaps today, what the real attack surfaces are, and why TEEs are a practical bridge to stronger cryptographic solutions. ](/blog/private-crosschain-atomic-swaps-part-2-of-2/)
* [  2026-03-06 · Yanis, Aaryamann Private Crosschain Atomic Swaps (Part 1 of 2) How to build atomic delivery-versus-payment across two chains while hiding amounts, prices, and counterparty identities. Part 1 covers the protocol: shielded UTXO notes, stealth addresses, and the coordination problem. ](/blog/private-crosschain-atomic-swaps-part-1-of-2/)
* [  2026-02-26 · Aaryamann Building Private Transfers on Ethereum with Plasma Explore how ZK-plasma enables private stablecoin transfers on Ethereum. Covers off-chain execution, balance proofs, and deployment tradeoffs for institutions. ](/blog/building-private-transfers-on-ethereum-with-plasma/)
* [  2026-02-19 · Aaryamann Building Private Transfers on Ethereum with Shielded Pools A proof-of-concept for compliance-first private stablecoin transfers using a shielded pool on Ethereum L1: covering KYC-gated entry, UTXO commitments, dual-key architecture, and ZK circuits in Noir. ](/blog/building-private-transfers-on-ethereum-with-shielded-pools/)
* [  2026-02-12 · Yanis Building Private Bonds on Ethereum - Part 3 Exploring Fully Homomorphic Encryption as a path to confidential institutional bonds on Ethereum, the third approach in our Private Bond PoC series. ](/blog/building-private-bonds-on-ethereum-part-3/)
* [  2026-02-05 · Yanis Building Private Bonds on Ethereum - Part 2 Part 2 of our private bonds series: we rebuild the same protocol on Aztec, where notes, nullifiers, and ZK proofs are handled by the network itself. 200 lines of Noir replace three separate components. ](/blog/building-private-bonds-on-ethereum-part-2/)
* [  2026-01-30 · Oskar Public Rails vs Private Ledgers An institutional decision framework for choosing between public blockchains with cryptographic privacy and private ledgers with trust-based privacy. ](/blog/public-rails-vs-private-ledgers/)
* [  2026-01-21 · Yanis Building Private Bonds on Ethereum A walkthrough of a proof-of-concept for private zero-coupon bonds using zero-knowledge proofs on Ethereum - covering the UTXO model, JoinSplit circuits, atomic swaps, and the relayer architecture. ](/blog/building-private-bonds-on-ethereum/)
* [  2026-01-09 · Oskar Cypherpunk x Institutional Privacy Exploring the overlap and tension between cypherpunks and institutions - and how the Institutional Privacy Task Force is mapping real institutional privacy requirements to solutions on Ethereum. ](/blog/cypherpunk-x-institutional-privacy/)
