Base adds ZK proofs to Base Azul with SP1. Base is partnering with Succinct to prove $7.4 billion in deposits with zero-knowledge proofs. Today, Succinct is announcing that Base is partnering with Succinct to bring zero-knowledge proofs to the Base chain. Base's Azul upgrade will use SP1 to prove $7.4 billion in deposits. This is a defining moment for Ethereum and its scaling roadmap. With Base upgrading to zero-knowledge, the largest layer 2 chains have validity proofs on their roadmap. Leading chains like Base use SP1 to generate their proofs, making SP1 critical infrastructure for chains that need speed and security. Proving Base with SP1. Base's current fault-proof system is optimistic and interactive: a batch of transactions is assumed valid unless someone challenges it within a 7-day window, slowing down withdrawals for $7.4B in assets. The upcoming Azul proof system upgrades Base to a multi-proof system combining TEE and ZK proofs as an intermediary step towards full ZK proving. When a ZK proof - generated by SP1 - and TEE proof back the same proposal, the Base chain unlocks three important properties: * Faster finality. Finality drops from seven days to one if a proposal to withdraw funds back to mainnet is backed by both a ZK and TEE proof. That means faster withdrawals and better capital efficiency. * Cryptographic security. Fault proofs rely on proposers to bond capital when submitting proposals. Azul's ZK path complements Base's existing security model with cryptographic guarantees that help prove correctness. * A path to Stage 2 decentralization. Reaching Stage 2 requires a way to detect proof system errors onchain. Azul accomplishes this through contradiction: ZK proofs are posted permissionlessly and override permissioned TEE proofs when the two disagree. The most advanced zkVM in production. Within the past year, several major chains have migrated from optimistic proof systems to ZK proofs. This is because zero-knowledge virtual machines (zkVMs) like SP1 have become increasingly performant and cheap. Generating ZK proofs for L2 blocks used to take hours and required writing bespoke circuits. SP1 lets teams write programs in standard Rust, compile to RISC-V, and generate ZK proofs of execution. With SP1, generating ZK proofs becomes fast, cheap, and production-ready for leading chains like Base. Over 35 customers, including rollups, bridges, exchanges, and DA layers use SP1 for its: * Performance. SP1 Hypercube is the first zkVM to deliver real-time proving for Ethereum, proving 99.7% of Ethereum mainnet blocks in under 12 seconds on 16 RTX 5090 GPUs. * Security. SP1 Hypercube is the first zkVM with complete formal verification of all 62 core RISC-V opcodes, completed with Nethermind Security and the Ethereum Foundation. * Trust. SP1 secures billions in TVL across the largest L2s and has generated millions of proofs on the Succinct Prover Network. $10B secured and counting. Base joins Optimism, Arbitrum, Polygon, Mantle, Celo, and more in implementing SP1 to secure over $10 billion in digital assets across major rollup ecosystems. The Ethereum rollup ecosystem is consolidating around ZK, with SP1 at the center.

Succinct unveils Zcam camera app to combat AI deepfakes. Succinct launches iPhone app to cryptographically verify photos. Cryptography company Succinct launched Zcam, an iPhone camera app that signs photos and videos at capture to help prove media authenticity in the AI era. Cryptography company Succinct has launched Zcam, an iPhone camera app that cryptographically signs photos and videos at the moment of capture to help prove their authenticity. The company said Thursday that Zcam embeds a tamper-evident record linking media to the device that captured it, allowing viewers to verify that content was not digitally altered or generated by artificial intelligence. How the Zcam application works. Source: Succinct According to Succinct, the app works by hashing raw image data and signing it using keys generated inside Apple's Secure Enclave, a hardware-based security module. The resulting signature, along with capture metadata and attestation, is embedded into the file using the Coalition for Content Provenance and Authenticity (C2PA) standard, a framework for attaching tamper-evident provenance data to digital media. Standards such as C2PA are designed to establish the origin and edit history of digital content by embedding signed provenance metadata into files. According to the C2PA, its open technical standard lets publishers, creators and consumers establish the "origin and edits" of digital content. It allows users to record how the content was created, which tools were used and how it changed over time. The launch pushes Succinct's applied cryptography work beyond blockchain infrastructure and into media provenance, as companies look for ways to authenticate digital content at creation rather than rely only on after-the-fact AI detection tools. The launch comes as security concerns in crypto increasingly include AI-driven fraud. On Thursday, blockchain security firm CertiK warned that deepfakes, phishing attacks and AI-assisted social engineering are likely to drive some of the largest crypto hacks in 2026. The report highlighted how attackers are using convincing synthetic media to deceive users and bypass security checks. Crypto security expands beyond code as AI threats rise. Succinct said Zcam is an early step toward broader adoption of cryptographic provenance tools, which could be used in areas such as journalism, insurance claims and identity verification, where trust in digital media is increasingly critical. The company acknowledged limitations in its current implementation, noting that the Zcam software development kit is unaudited and not production-ready. It also said secure enclaves have been compromised in the past and that ensuring a fully tamper-proof capture-to-signing process remains an active area of research.
