Repo markets run on cutoff windows, intraday credit lines, and settlement delays that create counterparty exposure from morning to close. Real-time 24/7 repo settlement with atomic DvP is in development on Cocoon. No cutoff windows. No intraday exposure accumulating between trades. Proof-backed audit trails verifiable by any regulator, without disclosing counterparty details. Settlement that matches the speed of the trade. erigon.tech/products/cocoon/ #Cocoon #Ethereum

Every regulatory reporting cycle forces a choice. Disclose enough to satisfy the regulator, exposing counterparty positions. Or protect the data and fail the obligation. ZK proofs remove that tradeoff. Cocoon proves compliance at the argument level: capital ratios, concentration limits, exposure thresholds. The underlying positions never leave the permissioned environment. erigon.tech/products/cocoon/ #Cocoon #Ethereum

Zilkworm's new design goes beyond basic post-state root checks, providing an elegant solution to the known risk of ExecutionWitness omission in stateless execution models. The answer is a hybrid approach combining verified witness consistency (pre-state) with lazy MPT validation at the point of read (during execution). This ensures the transition from Root A to Root B is mathematically bound to the canonical chain, without sacrificing proving speed.

Cross-border settlement between regulated institutions takes days, and each hop is a compliance event. Correspondent banks aren't just slow. They multiply the regulatory surface. Each jurisdiction, each intermediary, each cutoff creates a new reporting obligation. Cocoon targets settlement under 5 seconds, no correspondent bank required. One leg. One atomic transaction. One compliance proof. erigon.tech/products/cocoon/ #Cocoon #Ethereum

Traditional dark pools solve one problem by creating another. Hide the orders from the market? Yes. But also from regulators, from auditors, from anyone who needs to verify fair execution. Operators ask for trust they cannot prove they deserve. Cocoon flips the logic. The order book stays private to the market. A ZK proof attests every match followed the rules, anchored to Ethereum. Regulators get verifiable totals. Not your trades. erigon.tech/blog/cocoon-dark… #Cocoon #Ethereum

Tokenized MMF issuance should not require exposing your fund's balance sheet to the market. Cocoon runs MMF share issuance, transfer, and redemption on a private permissioned ledger. Automated yield distribution settles in minutes. ZK proof of reserves lets your regulator verify without seeing individual positions. Private to your counterparties. Provable to the auditor. erigon.tech/products/cocoon/ #Cocoon #Ethereum

On-chain transparency breaks down for size. Put a large order in a public mempool and bots front-run it before it fills. Dark pools solved this off-chain, but you had to trust the operator. Cocoon does both: the order book never touches a shared mempool, while ZK proofs let regulators verify totals and exposures without seeing individual trades. Privacy to the market, provability to the regulator. erigon.tech/blog/cocoon-dark… #Cocoon #Ethereum

🚢 Erigon v3.4.3 "Splashing Saga" has just shipped! This bugfix release is recommended for all users. Highlights: • Fixes a remaining post-reorg state leak that could cause gas accounting mismatches after tip reorgs. • Aligns debug_getModifiedAccounts* behavior with Geth semantics. • Fixes --rpc.logs.maxresults so CLI configuration is properly applied. • Improves Engine API performance by failing fast on backward downloads beyond the reorg limit. Includes additional stability and correctness improvements following the fixes introduced in v3.4.2. Release notes: github.com/erigontech/erigon… #Ethereum #Erigon

Cross-border payments often route through multiple intermediary banks. Processing time ranges from hours to days depending on the currency corridor. Each intermediary adds a fee, a liquidity hold, and a settlement risk window. Cocoon is developing cross-border payment infrastructure targeting settlement under 5 seconds, with no correspondent bank required. erigon.tech/products/cocoon/ #Cocoon #Ethereum

Regulated institutions face a tradeoff: share enough data to satisfy regulators, but not enough to expose sensitive positions. ZK proofs remove the tradeoff. Cocoon's regulatory reporting module lets institutions prove compliance — capital ratios, exposure limits, counterparty concentration — without revealing the underlying data. The regulator gets a verified statement. The portfolio stays private. cocoon.erigon.tech #Cocoon #Ethereum

🚨Erigon v3.4.2 is out! Bugfix release recommended for all users. This update fixes a state-leak issue that could surface after tip reorgs, improves receipt cache handling, and adds a DB/state merge improvement for smoother operation. Upgrade now! github.com/erigontech/erigon…

Most repo settlement still depends on end-of-day batch processes. The result: collateral locked, cash unavailable until cutoff. Intraday liquidity management becomes a negotiation with the settlement clock. Cocoon is developing real-time, 24/7 atomic DvP settlement for intraday repo. Collateral and cash settle simultaneously, programmatically, at any point in the day. erigon.tech/products/cocoon/ #Cocoon #Ethereum

Zilkworm supports pluggable RISC-V backends. Today, this means SP1 and SP1 HyperCube. However, work is ongoing with other teams to integrate additional backends. The execution trace is produced once by the C engine. The backend produces the ZK proof. Switching backends doesn't require re-implementing the EVM. This is what "pluggable prover backends" actually means in practice. Benchmark results across backends 👇 ethproofs.org #Zilkworm #Ethereum

Asset managers can now issue, transfer, and redeem MMF shares on Cocoon. Settlement is atomic. No T 2 lag, no correspondent bank in the loop, no settlement risk. Each transaction is ZK-verified: auditors confirm compliance without accessing raw portfolio data. Tokenized money market funds, built for regulated institutions. Available today. erigon.tech/products/cocoon/ #Cocoon #Ethereum

Most ZK provers are written in Rust. Erigon built Zilkworm in C . This wasn't a contrarian choice — it was the logical one. Silkworm and EVMone gave Erigon a decade of C EVM performance work. A ZK proving engine built on that foundation inherits every optimization already made to execution. Zilkworm isn't starting from scratch on cycle count. It starts where Ethereum's fastest execution left off. 🔗 erigon.tech/blog/introducing… #Zilkworm #Ethereum

EVMone is one of the most optimised EVM implementations ever written. It powers Erigon's execution engine and holds multiple performance records. Zilkworm is built on top of it. Every proving run starts from an execution trace generated by code that has been optimised for years at mainnet scale. Not a re-implementation. Not an approximation. The actual engine.

Regulatory reporting today forces a choice: share raw transaction data with auditors, or fail to prove compliance. Neither option is acceptable for institutions handling sensitive client positions. Cocoon removes the tradeoff. ZK proofs let regulated institutions demonstrate compliance at the protocol level — without disclosing the underlying data.
