A TOCTOU issue was reported by EF security in which two attestations
being validated at the same time may result in both of them being
forwarded. The spec says that we need to forward only the first one.

- Remove unnecessary `Copy()` call in `Eth1DataHasEnoughSupport`
- `data.Copy()` was called on every iteration of the vote counting loop,
even though `AreEth1DataEqual` only reads the data and never mutates it.
- Additionally, `Eth1DataVotes()` already returns copies of all votes,
so state is protected regardless.

The for loop in MigrateToCold function was brute force in nature. It
could be improved by just directly jumping by `slotsPerArchivedPoint`
rather than going over every single slot.
```
for slot := oldFSlot; slot < fSlot; slot++ {
...
if slot%s.slotsPerArchivedPoint == 0 && slot != 0 {
```
No need to do the modulo for every single slot.
We could just find the correct starting point and jump by
slotsPerArchivedPoint at a time.

The constructor `NewStateRootNotFoundError` incorrectly returned
`StateNotFoundError`. This prevented handlers that rely on
errors.As(err, *lookup.StateRootNotFoundError) from matching and mapping
the error to HTTP 404. The function now returns
StateRootNotFoundError and constructs that type, restoring the intended
behavior for “state root not found” cases.

This PR introduces flag `--ignore-unviable-attestations` (replaces and
deprecates `--disable-last-epoch-targets`) to drop attestations whose
target state is not viable; default remains to process them unless
explicitly enabled.
The head state is guaranteed to have the same shuffling and active
indices if the previous dependent root coincides with the target
checkpoint's in some cases.

Move the "Not enough connected peers" (for a given subnet) from WARN to
DEBUG
**Rationale:**
The
<img width="1839" height="31" alt="image"
src="https://github.com/user-attachments/assets/44dbdc8d-3e37-42ee-967b-75a7a1fbcafb"
/>
log is (potentially) printed every 5 minutes.
Every 5 minutes, the BN checks if, for a given subnet, the actual count
of peers is at least equal to a minimum one.
If not, this kind of log is printed.
When validators are connected and selected to be an aggregator in the
next epoch, the BN needs to subscribe and find new peers in the
corresponding attestation subnet.
If, right after the beacon is subscribed (but before it had time to find
peers), the "5 min ticker" ticks, then this warning log is displayed,
even if the slot for which the validator is selected as an aggregator is
still minutes away.
For this reason, this log is moved from WARN to DEBUG

The slot parameter in blobCacheEntry.filter was unused and redundant.
All slot/epoch-sensitive checks happen before filter
(commitmentsToCheck), and disk availability is handled via
BlobStorageSummary (epoch-aware).
Changes:
- Drop slot from blobCacheEntry.filter signature.
- Update call sites in availability_blobs.go and blob_cache_test.go.
Mirrors the data_column_cache.filter API (which does not take slot),
reduces API noise, and removes dead code without changing behavior.

This change ensures FlagOptions in cmd/beacon-chain/execution/options.go
appends only one endpoint option depending on whether a JWT secret is
present. Previously the code always appended WithHttpEndpoint and then
conditionally appended WithHttpEndpointAndJWTSecret which overwrote the
first option, adding unnecessary allocations and cognitive overhead.
Since WithHttpEndpointAndJWTSecret fully configures the endpoint,
including URL and Bearer auth needed by the Engine API, the initial
WithHttpEndpoint is redundant when a JWT is supplied. The refactor
preserves behavior while simplifying option composition and avoiding
redundant state churn.

**What does this PR do? Why is it needed?**
When unmarshaling a block with fastssz, if the target block's
`ExecutionRequests` field is nil, it will not get populated
```
if b.ExecutionRequests == nil {
b.ExecutionRequests = new(v1.ExecutionRequests)
}
if err = b.ExecutionRequests.UnmarshalSSZ(buf); err != nil {
return err
}
```
This is true for other fields and that's why we initialize them in our
gossip data maps. There is no bug at the moment because even if
execution requests are nil, we initialize them in
`consensus-types/blocks/proto.go`
```
er := pb.ExecutionRequests
if er == nil {
er = &enginev1.ExecutionRequests{}
}
```
However, since we initialize other fields in the data map, it's safer to
do it for execution requests too, to avoid a bug in case the code in
`consensus-types/blocks/proto.go` changes in the future.

**What type of PR is this?**
Feature
**What does this PR do? Why is it needed?**
This PR adds integrates state-diff into `HasState()`.
One thing to note: we are assuming that, for a given block root, that
has either a state summary or a block in db, and also falls in the state
diff tree, then there must exist a state. This function could return
true, even when there is no actual state saved due to any error.
But this is fine, because we have that assumption throughout the whole
state diff feature.
**Review after #16033 is merged**

Other
**What does this PR do? Why is it needed?**
This PR refactors the code to find the corresponding slot of a given
block root using state summary or the block itself, into its own
function `SlotByBlockRoot(ctx, blockroot)`.
Note that there exists a function `slotByBlockRoot(ctx context.Context,
tx *bolt.Tx, blockRoot []byte)` immediately below the new function. Also
note that this function has two drawbacks, which led to creation of the
new function:
- the old function requires a boltdb tx, which is not necessarily
available to the caller.
- the old function does NOT make use of the state summary cache.
edit:
- the old function also uses the state bucket to retrieve the state and
it's slot. this is not something we want in the state diff feature,
since there is no state bucket.
**What type of PR is this?**
Feature
**What does this PR do? Why is it needed?**
This PR integrates the state diff path into the `State()` function from
`db/kv`, which allows reading of states using the state diff db, when
the `EnableStateDiff` flag is enabled.
**Notes for reviewers:**
Files `kv/state_diff_test.go` and `config/features/config.go` only
contain renamings:
- `kv/state_diff_test.go`: rename `setDefaultExponents()` to
`setDefaultStateDiffExponents()` to be less vague.
- `config/features/config.go`: rename `enableStateDiff` to
`EnableStateDiff` to make it public.

**What does this PR do? Why is it needed?**
Previously, JWT secrets longer than 256 bits could cause client
compatibility issues. For example, Prysm would accept longer secrets
while Geth strictly requires exactly 32 bytes, causing Geth startup
failures when using the same secret file.
This change enforces the Engine API specification requirement that JWT
secrets must be exactly 256 bits (32 bytes), ensuring consistent
behavior across different client implementations.

## **Description:**
**What type of PR is this?**
> Bug fix
**What does this PR do? Why is it needed?**
Replaces fixed `time.Sleep(time.Second)` delays in `TestLifecycle` with
active polling to wait for service readiness/shutdown. This improves
test reliability and reduces execution time by eliminating unnecessary
waits when services start/stop faster than expected.
**Which issues(s) does this PR fix?**
N/A - Minor test improvement
**Other notes for review**
- Uses 50ms polling interval with 3s timeout for both startup and
shutdown checks
- Maintains same test logic while making it more efficient and less
flaky
- No functional changes to the service itself

This PR removes the last production usage for: `LastArchivedRoot` by
- extend the P2P config to accept a `StateGen` dependency and wire it up
from the beacon node
- update gossip scoring to read the active validator count via stategen
using last finalized block root
note: i think the correct implementation should process last finalizes
state to current slot, but that's a bigger change i dont want to make in
this PR, i just want to remove usages for `LastArchivedRoot`
**What type of PR is this?**
Bug fix
**What does this PR do? Why is it needed?**
This PR fixes a bug in the state diff `getBaseAndDiffChain()` method. In
the process of finding the diff chain indices, there could be a scenario
where multiple levels return the same diff slot number not equal to the
base (full snapshot) slot number.
This resulted in multiple diff items being added to the diff chain for
the same slot, but on different levels, which resulted in errors reading
the diff.
Fix: we keep a `lastSeenAnchorSlot` equal to the `BaseAnchorSlot` and
update it every time we see a new anchor slot. We ignore if the current
found anchor slot is equal to the `lastSeenAnchorSlot`.
Scenario example:
exponents: [20, 14, 10, 7, 5]
offset: 0
slots saved: slot 2^11, and slot (2^11 + 2^5)
slot to read: slot (2^11 + 2^5)
resulting list of anchor slots (diff chain indices): [0, 0, 2^11, 2^11,
2^11 + 2^5]
* stop emitting payload attribute events during late block handling when we are not proposing the next slot
* Change the behavior to not even enter FCU if we are not proposing next slot
* Vendor go-bip39 dependency locally to third_party/
The github.com/tyler-smith/go-bip39 repository has been deleted from GitHub
but is still needed for BIP-39 mnemonic functionality in the validator wallet
system. This change vendors v1.1.0 of the library into third_party/go-bip39/
to ensure continued availability.
Changes:
- Copy go-bip39 v1.1.0 source from Go module cache to third_party/go-bip39/
- Create BUILD.bazel files for main package and wordlists subpackage
- Update 5 BUILD.bazel files to reference local vendored version instead of external dependency
- Remove go-bip39 from go.mod and deps.bzl
- All builds and tests pass successfully
The vendored package includes all 9 language wordlists (English, Chinese Simplified/Traditional,
Czech, French, Italian, Japanese, Korean, Spanish) and maintains the original import paths for
compatibility.
* Changelog fraagment
* use go mod replace for vendored lib
* Run gazelle

This is our initial mainnet release for the Ethereum mainnet Fulu fork on December 3rd, 2025. All operators MUST update to v7.0.0 or later release prior to the fulu fork epoch `411392`. See the [Ethereum Foundation blog post](https://blog.ethereum.org/2025/11/06/fusaka-mainnet-announcement) for more information on Fulu.
Other than the mainnet fulu fork schedule, there are a few callouts in this release:
-`by-epoch` blob storage format is the default for new installations. Users that haven't migrated will see a warning to migrate to the new format. Existing deployments may set `--blob-storage-layout=by-epoch` to perform the migration.
- Several deprecated flags have been deleted! Please review the "removed" section of this changelog carefully. If you are referencing a removed flag, Prysm will not start! All of these flags had no effect for at least one release.
- Several deprecated API endpoints have been deleted. Please review the "removed" section of this changelog carefully.
- Backfill is not supported in Fulu. This is expected to be fixed in the next release and should be delivered prior to the mainnet activation fork.
- The builder default gas limit is raised from `45000000` (45 MGas) to `60000000` (60 MGas).
- Several bug fixes and improvements.

- Fixed web3signer e2e, issues caused due to a regression on old fork support. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15832)
- Do not mark blocks as invalid from ErrNotDescendantOfFinalized. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15846)
- Fixed [#15812](https://github.com/OffchainLabs/prysm/issues/15812): Gossip attestation validation incorrectly rejecting attestations that arrive before their referenced blocks. Previously, attestations were saved to the pending queue but immediately rejected by forkchoice validation, causing "not descendant of finalized checkpoint" errors. Now attestations for missing blocks return `ValidationIgnore` without error, allowing them to be properly processed when their blocks arrive. This eliminates false positive rejections and prevents potential incorrect peer downscoring during network congestion. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15840)
- Mark the block as invalid if it has an invalid signature. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15847)

- Fix `/eth/v1/beacon/blob_sidecars/` beacon API is the fulu fork epoch is set to the far future epoch. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15867)
-`dataColumnSidecarsByRangeRPCHandler`: Gracefully close the stream if no data to return. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15866)
-`VerifyDataColumnSidecar`: Check if there is no too many commitments. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15859)
-`WithDataColumnRetentionEpochs`: Use `dataColumnRetentionEpoch` instead of `blobColumnRetentionEpoch`. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15872)
- Mark epoch transition correctly on new head events. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15871)
- reject committee index >= committees_per_slot in unaggregated attestation validation. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15855)
- Decreased attestation gossip validation batch deadline to 5ms. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15882)
