FROM 60M TO 200M: SIMULATING GLAMSTERDAM'S FEE MARKET

Ethereum researchers simulated Glamsterdam's proposed gas limit increase from 60M to 200M across 12 demand scenarios, replaying 21 days of mainnet transactions through an instrumented reth fork with 50 simulation paths per scenario. After a 10-hour adjustment period, nine of twelve scenarios settled near 50% block utilization, with median base fees ranging from under 0.0001 gwei to 0.39 gwei depending on demand level and price elasticity. Three low-demand scenarios failed to reach the 100M-gas utilization threshold even at near-zero base fees, shifting gas costs to priority tips at a median of 0.025 gwei. At 2x demand, base fees varied 18-fold across elasticity assumptions (0.006 to 0.106 gwei), indicating block utilization alone cannot predict post-upgrade fee outcomes.

FINANCING THE NEXT HUNDRED STABLECOIN-LINKED CARD PROGRAMS

Visa's stablecoin-linked card ecosystem has grown to 160+ active programs with $20 billion in annualized settlement volume, up 15x year over year, but early-stage issuers face a structural gap: daily settlement obligations must be funded before cardholders pay, at sizes too small to justify traditional warehouse facility costs. Credit Coop built a stablecoin-denominated revolving credit facility secured by settlement receivables, routing repayments through a Spigot smart contract and calibrating underwriting directly from Visa settlement files, cutting borrowing costs for participating programs by as much as 30%. The facility has financed over $2.5 billion in cumulative volume since 2023 with zero defaults and more than 9,000 onchain repayment events, serving programs including Rain (a Visa Principal Member) and Karta. The next phase adds just-in-time disbursements triggered directly by daily Visa settlement files, so programs pay for capital only during the hours it is deployed rather than maintaining a standing draw.

BLOOM FILTERS AND KEYED NONCES

EIP-8250 proposes replacing Ethereum's single per-account nonce with multiple independent keyed nonces stored in a NONCE_MANAGER system contract, serving use cases such as privacy pools running UTXO/nullifier models and accounts with independent authenticated signers. Under weak statelessness, each nonce key compounds VOPS storage requirements, prompting researchers to examine bloom filters as a compression mechanism that cuts per-nonce storage from roughly 64 bytes to 1-2 bytes by testing only whether a nonce equals zero. The approach breaks for non-binary nonces: those variants produce two-sided errors that let attackers push invalid transactions through mempool validators, which the one-sided bloom filter design specifically avoids. Researchers propose reserving the first byte of each nonce key as a nonce-type tag at creation time, separating binary from non-binary nonces and allowing the storage optimization to activate retroactively once statelessness launches with minimal changes to the EIP.
