Glamsterdam Upgrade On Hold: Ethereum Devs Halt Hoodi Fork
The Ethereum Glamsterdam upgrade is on hold. Core developers will not fork the Hoodi testnet until a set of gas-related smart contract risks is resolved, according to an Ethereum Foundation blog post dated November 6. Cointelegraph reports the same decision.
Why the Glamsterdam upgrade stalled
The problem comes from two proposals, EIP-8037 and EIP-8038. They change how gas is charged for state creation and state access. Auditor ChainSecurity published a review on October 13. It found that, with unchanged contract code, a failure path that used to revert can now complete.
That matters for contracts that catch failed calls and then check how much gas is left. For example, a forced failure could disable a retry or remove a claim. The Foundation refers to “eight invariants” that the new rules break. It says it cannot check every project, so it is working with ChainSecurity and Dedaub.
What happens next
First, the next All Core Devs calls must work out what could break and whether spec changes can prevent it. Meanwhile, Glamsterdam went live on the Sepolia testnet on October 6, and work on Hegota continues in parallel. Neither source gives a new Hoodi date or a mainnet date. The Foundation asks affected projects to write to glamsterdam@ethereum.org.
Does the Glamsterdam upgrade matter to bitcoin miners?
Not directly. Ethereum is proof of stake, so no ASIC or GPU earns block rewards there. This is a software schedule story, not a hashprice story. Still, it is a useful reminder of how slow and careful upgrades should be. And it matters to anyone who holds ETH or runs contracts.
Miner math: bitcoin margins are unchanged by Ethereum’s delay
Here is the live maths on November 7. Bitcoin is $75,752 and the network is 1007 EH/s, so hashprice is about $34.12 per petahash per day. That is what one PH/s of hashing earns before power.
| Machine | 5c/kWh | 8c/kWh | 12c/kWh | Break-even |
|---|---|---|---|---|
| Antminer S19 (95 TH/s, 3250 W) | -$0.66 | -$3.00 | -$6.12 | 4.2c |
| Antminer S19k Pro (115 TH/s, 2645 W) | $0.75 | -$1.15 | -$3.69 | 6.2c |
| Antminer S19 XP (141 TH/s, 3010 W) | $1.20 | -$0.97 | -$3.86 | 6.7c |
| Antminer S21 Pro (234 TH/s, 3510 W) | $3.77 | $1.25 | -$2.12 | 9.5c |
Numbers are profit per day after electricity, at the three power prices shown. Break-even is the most you can pay per kilowatt-hour before the machine loses money.

The table is the honest answer for mining. Nothing in this delay changes bitcoin difficulty, hashrate or hashprice. What does move your margin is the bitcoin price and your power cost. We track the wider market in our Bitcoin price prediction, and our mining economics guides show the break-even arithmetic.
