Fusaka and Glamsterdam: what home stakers need to know
By AVADO team · Published
Fusaka is the Ethereum upgrade that went live on mainnet on 3 December 2025. Its main change is PeerDAS (EIP-7594): nodes no longer download all blob data, only a sample of it. For a home staker this means less disk space and download bandwidth, but more upload bandwidth. The next upgrade, Glamsterdam, is planned for late 2026 but has no confirmed date yet. It followed Pectra, which went live in May 2025.
What did Fusaka change?
Fusaka’s main changes are these:
| Change | EIP | What it means |
|---|---|---|
| PeerDAS (data availability sampling) | EIP-7594 | Nodes hold a fraction of blob data instead of all of it |
| Blob-parameter-only forks | EIP-7892 | Blob capacity can grow in small steps without a full upgrade |
| Default gas limit of 60 million | EIP-7935 | More room for transactions in each block |
| Gas cap per transaction | EIP-7825 | No single transaction can use more than about 16.8 million gas |
| Block size limit | EIP-7934 | Execution blocks are limited to 10 MiB |
| Deterministic proposer lookahead | EIP-7917 | Block proposers are known further in advance, which helps preconfirmations |
| History expiry groundwork | EIP-7642 | Clients prepare to drop old chain history |
| secp256r1 precompile | EIP-7951 | Wallets can use passkeys, like the ones on phones |

How does Fusaka affect my node?
Fusaka’s main effect on a node is on bandwidth and disk use, and it depends on how much ETH the node runs. According to ethereum.org:
- Solo stakers: disk use and download bandwidth for blob data fall by around 50%, but upload bandwidth needs to be two to three times higher.
- Nodes with 800 ETH or more: these keep more blob data and need around 30% more download bandwidth.
- Very large nodes (4,096 ETH or more) act as “supernodes”, keep all blob data and need about 20 Mbps of sustained bandwidth.

For most home stakers the only thing to check is your upload speed and that your internet plan has no data cap. See the staking hardware requirements for 2026.
Do I need to do anything on my AVADO?
No action is needed if your AVADO has installed its updates since 3 December 2025: it runs Fusaka. Your node needed Fusaka-ready client versions before that date. The AVADO team packages client releases for network upgrades, and with auto-update on (the default) your box installs them by itself. If you’re not sure, open the Admin UI and install any updates it offers.
Priority Care subscribers also get a warning when a network upgrade deadline is close or an installed app has a known bad version.
What is Glamsterdam?
Glamsterdam is the next planned Ethereum upgrade. Its two headline changes are:
- Enshrined proposer-builder separation (ePBS, EIP-7732): builds the split between block proposers and block builders into the protocol, instead of relying on outside relays as MEV-Boost does today.
- Block-level access lists (EIP-7928): blocks say in advance which accounts and storage they touch, so clients can process them in parallel. This is a step towards higher gas limits.
When is Glamsterdam going live?
Glamsterdam’s mainnet date is not confirmed yet. As of September 2026 it is targeted for the fourth quarter of 2026, after an earlier target slipped because ePBS took longer than expected. It will activate on the public testnets (Sepolia and Hoodi) before mainnet. We’ll package the client releases when they’re out, and your AVADO will offer them as usual.
Until the date is set, there’s nothing to do. Keep your AVADO updated, and follow the AVADO blog or the Discord community for the announcement.
