The Ethereum Foundation took a bold step toward making privacy a default feature of the network on September 14, 2025, officially rebranding its Privacy and Scaling Explorations team as the “Privacy Stewards of Ethereum” and unveiling a comprehensive zero-knowledge proof roadmap designed to integrate privacy features directly into the Layer 1 protocol by the end of the year.
The announcement, which coincided with a wave of infrastructure developments across the broader blockchain ecosystem, signals Ethereum’s most ambitious privacy push to date and comes at a time when zero-knowledge technology is rapidly maturing from theoretical promise to production-ready infrastructure.
TL;DR
- Ethereum Foundation rebrands PSE team to “Privacy Stewards of Ethereum” with a three-track privacy roadmap
- Linea launches “Ignition” liquidity program, allocating 160 million tokens to DeFi with TVL reaching $1.32 billion
- Hyperliquid selects Native Markets to issue USDH stablecoin, backed by BlackRock-managed reserves
- Boundless Network goes live on mainnet with novel “Proof of Verifiable Work” consensus for ZK proving
- Monero suffers record 18-block chain reorganization, highlighting security challenges for privacy-focused networks
The Privacy Stewards of Ethereum
The rebranding of the Privacy and Scaling Explorations team to the Privacy Stewards of Ethereum represents more than a name change. The newly christened team introduced a formal three-track privacy strategy that aims to embed zero-knowledge technology at every level of the Ethereum stack.
The first track, dubbed “Private Writes,” focuses on enabling shielded transactions that hide sender, receiver, and amount details while maintaining full compatibility with existing smart contracts. The second track, “Private Reads,” introduces privacy-preserving RPC queries that prevent third parties from inferring user intent based on the data they request from the network. The third track, “Private Proving,” aims to enable zero-knowledge proof generation on consumer hardware, including smartphones, making privacy accessible to everyday users rather than requiring specialized computing infrastructure.
Perhaps most significantly, the roadmap includes a target to integrate an L1 zkEVM — a zero-knowledge execution environment — directly into the Ethereum mainnet by late 2025. If achieved, this would allow all Ethereum transactions to benefit from privacy guarantees without requiring users to interact with separate Layer 2 networks or specialized applications.
PlasmaFold: A New L2 Architecture
Alongside the privacy roadmap, developers detailed a new Layer 2 design called PlasmaFold on September 14. Unlike traditional optimistic rollups that require a 7-day withdrawal period, PlasmaFold leverages ZK proofs to enable private transfers while eliminating the cumbersome “exit game” delays that have plagued earlier plasma and rollup designs.
The architecture represents a hybrid approach that borrows the data availability guarantees of plasma constructions with the cryptographic finality of ZK rollups. Early benchmarks suggest PlasmaFold could achieve transaction finality in under 30 seconds while maintaining full privacy for user transfers, a significant improvement over the multi-day waiting periods common in current optimistic rollup implementations.
Linea Ignition and the DeFi Liquidity Race
ConsenSys-backed Layer 2 network Linea made waves with the launch of its “Ignition” liquidity program, allocating 160 million LINEA tokens to incentivize DeFi activity on the network. The LINEA token surged approximately 20% in the 24 hours following the announcement, trading between $0.029 and $0.031 as exchange listings expanded.
Linea’s total value locked reached $1.32 billion, positioning it among the top tier of Ethereum Layer 2 networks. The Ignition program distributes tokens across lending protocols, decentralized exchanges, and yield vaults, creating a comprehensive incentive structure designed to attract both retail users and institutional liquidity providers.
USDH: A BlackRock-Backed Stablecoin on HyperEVM
High-performance decentralized exchange Hyperliquid concluded a competitive bidding process by selecting Native Markets as the issuer for USDH, a new stablecoin built natively on HyperEVM. The project features an unusual custody structure: BlackRock manages the off-chain treasury reserves, while Superstate handles tokenized on-chain reserve yields through Stripe’s Bridge platform.
USDH represents a growing trend of traditional finance giants directly backing crypto-native stablecoin infrastructure. By combining BlackRock’s institutional credibility with the transparency of on-chain reserves, the project aims to bridge the trust gap between traditional and decentralized finance. The stablecoin will compete with established players like USDC and DAI in the growing market for transparent, yield-bearing stable assets.
Boundless Network and Proof of Verifiable Work
The Boundless Network launched its mainnet on September 14, introducing a novel consensus mechanism called Proof of Verifiable Work. Unlike traditional proof-of-work mining that secures a single chain, PoVW specifically rewards nodes for generating ZK proofs that can be used by external rollups and bridges. The network’s ZKC token began trading following the launch.
The approach creates what developers describe as a “universal proving layer” — a decentralized network of provers that can generate zero-knowledge proofs for any compatible blockchain. If successful, Boundless could significantly reduce the cost and complexity of operating ZK rollups by outsourcing the computationally intensive proving process to a dedicated network.
Monero’s Record Reorg Raises Security Questions
Not all blockchain developments on September 14 were positive. Privacy coin Monero experienced its deepest-ever chain reorganization, with 18 blocks — representing approximately 36 minutes of transaction history — being rolled back. The incident, attributed to the Qubic mining pool controlling over 51% of the network’s hashrate, invalidated 118 confirmed transactions.
Paradoxically, XMR prices climbed 7.2% to $174.40 on the same day as traders appeared to bet on a technical resolution to the mining centralization issue. The reorganization, however, reignited regulatory discussions about the stability of privacy-focused networks and the potential need for exchanges to implement additional safeguards for assets with known consensus vulnerabilities.
Why This Matters
September 14, 2025 was a banner day for blockchain infrastructure. Ethereum’s commitment to privacy-by-default, Linea’s massive liquidity injection, the BlackRock-backed USDH stablecoin, and Boundless’s novel proving network all point to a maturing ecosystem where the building blocks of a privacy-preserving, scalable, and institutionally connected financial system are being assembled. The Monero incident serves as a reminder that technical challenges remain, but the overall trajectory is unmistakable: the infrastructure layer is getting stronger, faster, and more private with each passing week.

private writes AND private reads in the same roadmap? if they actually ship both this year it would be the biggest privacy upgrade ethereum has ever had
Rebranding from PSE to Privacy Stewards feels mostly symbolic. What matters is whether they can deliver shielded transactions without gas costs going through the roof.
^ the gas concern is legit. ZK verification on L1 is expensive. they need Pectra-level blob support to make this economical
meanwhile monero just had an 18-block reorg. timing is ironic when the biggest privacy coin cant keep its chain stable
