### Announcements

- [Sipher Vault: Devnet Beta is Open](https://blog.sip-protocol.org/blog/sipher-vault-devnet-beta-open/)
  Sipher Vault devnet beta is open. It closes the sender-side privacy gap stealth addresses alone cannot fix — authority-signed CPI to sip_privacy breaks the on-chain link between sender wallet and stealth recipient.
- [SIP Roadmap 2026: The Path to Privacy Standard](https://blog.sip-protocol.org/blog/sip-roadmap-2026-explained/)
  SIP is executing a 6-milestone strategy: M17 (Solana same-chain) and M18 (EVM same-chain) build the foundation. M19-M20 create a technical moat through proof composition. M21 formalizes SIP as an industry standard. M22 enables institutional and AI agent adoption.

  The SIP Protocol blog is live! Follow us for technical deep-dives on privacy tech, ecosystem updates, tutorials, and our vision for making privacy the standard in Web3.

### Tutorials

- [privacy on solana, explained like youre not a cryptographer](https://blog.sip-protocol.org/blog/privacy-without-jargon/)
  every transaction you make on solana is public. everyone can see your balance, who paid you, who you paid. this is a problem. privacy fixes it.
- [stealth addresses: one-time addresses without the math](https://blog.sip-protocol.org/blog/stealth-addresses-for-humans/)
  stealth addresses generate a fresh address for every payment you receive. only you can find and spend the money. no one can link your payments together.
- [viewing keys: how to be private AND compliant](https://blog.sip-protocol.org/blog/viewing-keys-tldr/)
  viewing keys give read-only access to your transactions. share with your accountant for taxes, auditor for compliance, nobody else. private by default, transparent when needed.
- [Building with Arcium: Your First MPC Application](https://blog.sip-protocol.org/blog/building-arcium-mpc-application/)
  Use Arcis CLI to scaffold MPC projects, define encrypted types with #[derive(Encrypted)], write programs that compute over encrypted data, and integrate with TypeScript client using @arcium/sdk.
- [SIP SDK: Your First Private Transaction](https://blog.sip-protocol.org/blog/getting-started-sip-sdk/)
  Install @sip-protocol/sdk, create stealth addresses for private receiving, use Pedersen commitments to hide amounts, and generate viewing keys for compliance. Full working examples included.

### Thought-leadership

- [The Complete Guide to Crypto Privacy](https://blog.sip-protocol.org/blog/complete-privacy-guide/)
  Your crypto wallet is public. This guide explains 6 different privacy approaches, their trade-offs, and why SIP combines them all with compliance-ready viewing keys.
- [Privacy for Humans: A Jargon-Free Guide](https://blog.sip-protocol.org/blog/privacy-for-humans/)
  Crypto privacy explained with zero jargon. Secret PO boxes hide who you are. Locked safes hide how much you have. Spare keys let you share with people you trust. Simple.
- [Wallet Surveillance Exposed: Who is Tracking You?](https://blog.sip-protocol.org/blog/wallet-surveillance-exposed/)
  Companies like Chainalysis and Arkham track every crypto transaction. They link wallets, correlate timing, and sell your data to governments and corporations. Your financial life is an open book—but solutions exist.
- [The 1000-Year Blockchain: Which Chains Will Survive?](https://blog.sip-protocol.org/blog/the-1000-year-blockchain/)
  Most blockchains face an existential security budget crisis when block rewards end. Our analysis scores 7 major chains on 1000-year survival probability—Ethereum leads at 65%, while Bitcoin faces serious challenges at 25%.
- [Crypto Privacy for Humans: No Jargon, Just Facts](https://blog.sip-protocol.org/blog/crypto-privacy-for-humans/)
  Every crypto transaction is public forever. Privacy solutions differ: pool mixing hides you in a crowd, cryptographic privacy uses math. SIP uses math-based privacy plus viewing keys so you choose who sees what.

### Technical

- [Noir ZK Proofs on Solana: A Production Implementation](https://blog.sip-protocol.org/blog/noir-zk-proofs-solana/)
  We built 3 production Noir circuits (3,776 ACIR opcodes) with browser WASM support, 86 tests, and Solana integration. Noir enables privacy proofs that hide balance, sender identity, and transaction details while remaining compliant.
- [MPC and Confidential Computing: How Arcium Works](https://blog.sip-protocol.org/blog/mpc-confidential-computing-arcium/)
  Arcium uses Multi-Party Computation (MPC) across distributed nodes to compute over encrypted data. No single node sees the plaintext. C-SPL tokens enable confidential balances while keeping recipients public.
- [Pedersen Commitments: The Math Behind Amount Hiding](https://blog.sip-protocol.org/blog/pedersen-commitments-explained/)
  Pedersen commitments hide values using C = v*G + r*H. The magic: they are additively homomorphic, meaning you can verify C(a) + C(b) = C(a+b) without knowing a or b. This enables balance verification without revealing amounts.
- [The State of Privacy on Solana (2026): A Technical Overview](https://blog.sip-protocol.org/blog/solana-privacy-landscape-2026/)
  Solana has five main privacy approaches: pool mixing (PrivacyCash), bulletproofs (ShadowWire), MPC (Arcium), TEE (Inco), and cryptographic middleware (SIP). Each has different trade-offs in latency, privacy guarantees, and compliance features.
- [Stealth Addresses Explained: EIP-5564 and Recipient Privacy](https://blog.sip-protocol.org/blog/stealth-addresses-eip-5564/)
  Stealth addresses create unique one-time addresses for each payment. Only the recipient can detect and spend funds sent to them. This prevents tracking by address reuse and provides complete recipient privacy.

### Ecosystem

- [a16z Big Ideas 2026: Privacy is Crypto's Next Moat](https://blog.sip-protocol.org/blog/a16z-big-ideas-2026-validates-sip/)
  a16z's 2026 predictions validate SIP's core thesis: privacy creates network effects, and agents need cryptographic credentials. SIP delivers both with viewing keys.
