Here we report on the progress of the leading builders in the Privacy ecosystem, documenting recent significant releases, technical breakthroughs and general updates.
Featuring @zksync, @StarkWareLtd/@Starknet, @Scroll_ZKP, @aztecnetwork, @taikoxyz, @0xPolygon, @ZircuitL2, & @kroma_network 👇
ZKsync
@zksync has introduced Airbender, a high-speed open-source zkVM based on RISC-V:
Benchmark tests show Airbender delivers sub-second ZKsync block proofs and proves @ethereum blocks in under 35 seconds using a single GPU - dramatically outperforming existing systems that require dozens more. It also cuts proving costs by over 10x and supports consumer-grade hardware.
Designed for integration across the Elastic Network, it replaces the Boojum prover and enables near real-time cross-chain interoperability. Though still in beta, Airbender is available now for developers to build and test.
Scroll
🔷 Launches 🔷
@Scroll_ZKP has launched the Scroll Audit Marketplace on Areta Market, giving developers a quicker, clearer route to smart-contract security reviews:
Builders submit their scope once and receive six to eight competitively priced proposals, cutting typical wait times from weeks to days and lowering fees by up to 30 percent.
All participating auditors - @hackenclub, @immunefi, @spearbit, @NethermindEth, @sherlockdefi, @zellic_io, @CertoraInc, @hexensio, and @rv_inc - have been vetted by Areta, ensuring standardized terms, transparent pricing, and greater confidence before deployment for teams on mainnet.
🔷 Integrations 🔷
Scroll also is now supported by @zkp2p, enabling users to onramp through familiar apps like Revolut, Venmo, Cash App, and Wise. This provides global access with local convenience, moving closer to a truly open economy:
Aztec
@aztecnetwork has integrated @ZKPassport into its Testnet to help combat Sybil attacks by verifying user humanity without compromising privacy:
Using ZKPs, users prove they hold a valid ID without sharing personal data. This enables more legitimate node operators to join the validator set, increasing decentralization.
ZKPassport runs entirely on users’ devices, ensuring privacy, security, and permissionless participation in the Web3 ecosystem.
Taiko
@taikoxyz has announced a partnership with security firm @Hashlock_ to enhance its Taiko Takeoff program, a community-driven initiative supporting early-stage projects on Taiko’s decentralized ZK Rollup:
Participating projects will receive a 10% discount on audit fees, a month of free bug bounty coverage post-audit, and marketing support. The collaboration aims to strengthen the security and visibility of projects building within the Taiko ecosystem.
In addition, @HotcoinGlobal has joined Taiko as a strategic partner in the Taiko Takeoff Program. With over $1.5 million in grants and 45+ partners, the program offers funding, mentorship, technical support, and user exposure to help teams scale more efficiently and build securely on Taiko:
Polygon
Polygon has released plans to scale to 100,000 transactions per second by 2026, aiming to support real-world payments and tokenized assets:
A July upgrade will deliver 1,000 TPS and 5-second finality, rising to 5,000 TPS via @Agglayer by year-end.
Backed by active institutional use and strong stablecoin velocity, Polygon combines low fees, speed, and interoperability to become a key blockchain for onchain finance and global economic infrastructure.
Zircuit
@ZircuitL2 is integrating with @SindriLabs after months of planning and testing:
Sindri provides scalable infrastructure for cryptographic workloads, supporting SP1 zkVM by @SuccinctLabs and Jolt zkVM by @a16zcrypto.
Zircuit engineers have updated Kona for Sequencer Level Security and optimized OP-Succinct with Sindri’s cloud provers. Internal testnets using SP1 zkVMs are nearly ready for public launch, ahead of a mainnet release.
