Bug fix
**What does this PR do? Why is it needed?**
It appears that #16216 introduced hashtree integration but broke builds
on macOS Intel (darwin_amd64).
```
Error:
Undefined symbols for architecture x86_64:
"_github.com/OffchainLabs/hashtree.HashtreeHash"
```
The Bazel patch for hashtree was missing `wrapper_darwin_amd64.s`. So,
`//go:noescape` in `bindings.go` assumes that symbols are available
elsewhere, and while on other platforms optimized version is used, on
Darwin we have stub (symbol still must be available), which needs to be
referenced -- hence, this PR.
**Other notes for review**
I've re-checked using `bazel clean && bazel build //cmd/beacon-chain` --
it was failing before, works now.

This PR adds gloas specific time basis points for validator duties
(attestation, aggregation, and sync contribution) and wires the
validator client to use them once `GloasForkEpoch` is active. For now,
`GloasForkEpoch` is set to far-future so behavior is unchanged until the
fork epoch is configured
Note to the rev: today sync message duty uses `waitOneThirdOrValidBlock`
which shares with attestation dead line, that's why sync message bps is
not used
Initialize state-diff database on new node startup
When starting a node with --enable-state-diff feature flag, the database
is now initialized appropriately based on the startup scenario:
- New database + checkpoint sync: Set offset to checkpoint state slot,
save checkpoint state as full snapshot
- New database + genesis sync: Set offset to 0, save genesis state as
full snapshot
- Existing database without state-diff: Log warning that feature is
ignored due to old schema
- Existing database with state-diff: Return error (restarts will be
handled in a future PR)

**What does this PR do? Why is it needed?**
This PR adds the `cmd` directory and all it's subcategories to the
`hack/gen-logs.sh`. meaning that they will now have a `log.go` file and
a `package` field. see the list of added packages below. some of them
had different names, which has been added to the `prefixReplacements`
map.
packages added:
"cmd"
"cmd/validator/web"
"cmd/validator/wallet"
"cmd/validator/slashing-protection"
"cmd/validator/db"
"cmd/validator/accounts"
"cmd/prysmctl"
"cmd/prysmctl/weaksubjectivity"
"cmd/prysmctl/validator"
"cmd/prysmctl/testnet"
"cmd/prysmctl/p2p"
"cmd/prysmctl/db"
"cmd/prysmctl/checkpointsync"
"cmd/client-stats"
"cmd/beacon-chain"
"cmd/beacon-chain/storage"
"cmd/beacon-chain/jwt"
"cmd/beacon-chain/genesis"
"cmd/beacon-chain/flags"
"cmd/beacon-chain/db"
This PR moves consolidation and withdrawal request processing into
neutral package: `beacon-chain/core/requests`, such that they can be
shared between fork
Why?
Today our core packages are mixed between two workflows: older forks
calling into newer forks, and newer work calling back into older fork
code. No matter which direction we settle on long-term, a clear first
step is to move shared cross-fork functionality into a neutral place so
we can reuse it later such that if fork A and fork B interleave each
other, they can become clear abstractions
Why git mv wasn’t used for consolidations?
Withdrawals lived in a clean, dedicated file so it was moved with git
mv. Consolidation logic was interleaved with other Electra code and
needed extraction/refactor, so a pure git mv would not have preserved
meaningful history
**What does this PR do? Why is it needed?**
Fixing a bug in `check-logs.sh` where untracked files were ignored.
for example PR #16216 passed the check while it shouldn't have. this
change fixes the problem.
**What does this PR do? Why is it needed?**
Adds a log mentioning the name and the version of the app:
Beacon-chain:
```
[2026-01-26 12:03:12.91] INFO main: Prysm Beacon Chain started. [Prysm/Unknown/Local build. Built at: Moments ago] prefix=main
```
Validator:
```
[2026-01-26 12:00:07.38] INFO main: Prysm Validator started. [Prysm/v7.1.2/7950a249266a692551e5a910adb9a82a02c92040. Built at: 2026-01-06 18:47:23+00:00] prefix=main
```
**Note:** I've removed the previous two logs that mentioned version in
favor of these new ones. I've also moved the initialization logs of
persistent log file and ephemeral log file to DEBUG.

This refactors `ExpectedWithdrawals` to use shared helpers for pending
partial withdrawals and the validator sweep. The goal is to keep the
logic spec-aligned while making it easier to reuse across future forks.
```
**Example (Gloas expected withdrawals order):**
builder withdrawals
pending partial withdrawals
builder sweep withdrawals
validator sweep withdrawals
```
Note to reviewers: the helpers take a `*[]*enginev1.Withdrawal` so we
can append efficiently without returning/re-appending slices.
- moves deposit-related helpers (deposit signature verification, batch
verification, merkle proof verification, and activation helper) from
`beacon-chain/core/blocks` into `beacon-chain/core/helpers`
- updates call sites (Altair/Electra) to use helpers
Why?
- In gloas, the blocks package needs to call into gloas logic (e.g.
clearing builder pending payments/withdrawals on proposer slashing)
- gloas also introduces deposit-request processing which needs deposit
signature verification previously located in blocks.
That creates a Bazel/Go dependency cycle (blocks -> gloas -> blocks)
- the natural layering is for blocks and fork logic to depend on a lower
level util package for deposit verification, so moving deposit helpers
to core/helpers breaks the cycle
**What type of PR is this?**
Feature
**What does this PR do? Why is it needed?**
This PR adds a `--log.vmodule` flag to the beacon-chain and validator
apps, that allows setting a different verbosity for every* package.
*: not every package, but most packages. (all packages that define their
logger variable with a `package` field)
Combined with the `--verbosity` flag this allows users to control
exactly what they see.
This affects both the terminal and the log file (`--log-file`), but not
the ephemeral debug log file.
example usage:
```
./beacon-chain --log.vmodule=beacon-chain/p2p=info,beacon-chain/sync=error,beacon-chain/sync/initial-sync=debug
```
There are improvements to be done later, like accepting just the package
name instead of the full path, etc.

**What does this PR do? Why is it needed?**
Allow a flag to be hidden and hide the `--disable-get-blobs-v2` flag.
This flag is still usable, but does not show up any more in the help.
This flag is used for internal purpose only, so no need to expose it
publicly.
**Why do we need to modify the `cli.HelpPrinter` function whereas other
flags like `--aggregate-first-interval` are hidden just by using the
`Hidden: true` property?**
The `Hidden: true` property on the flag definition doesn't work by
itself because `usage.go` uses a custom help template that bypasses the
standard urfave/cli help rendering.

This PR fixes a security vulnerability where authenticated endpoints
could be accessed without authorization by using direct
`/v2/validator/*` paths instead of `/api/v2/validator/*`.
The `AuthTokenHandler` middleware only checked for authentication on
requests containing `/api/v2/validator/` or `/eth/v1` prefixes, but the
same handlers are also registered for direct `/v2/validator/*` routes.
This allowed attackers to bypass authentication by simply removing the
`/api` prefix from the URL.

Introduces a `completion` subcommand to `beacon-chain` and `validator`
that outputs shell completion scripts. Supports Bash, Zsh, and Fish
shells.
```bash
# Load completions in current session
source <(beacon-chain completion bash)
# Persist for future sessions
beacon-chain completion zsh > "${fpath[1]}/_beacon-chain"
validator completion fish > ~/.config/fish/completions/validator.fish
```
Once loaded, users can press TAB to complete subcommands, nested
commands, and flags. Flag completion supports prefix matching (e.g.,
typing `--exec<TAB>` suggests `--execution-endpoint`,
`--execution-headers`).
**Which issues(s) does this PR fix?**
Fixes#16244
**Other notes for review**
The implementation adds three files to the existing `cmd` package:
- `completion.go` - Defines `CompletionCommand()` returning a
`*cli.Command` with `bash`, `zsh`, `fish` subcommands
- `completion_scripts.go` - Contains the shell script templates
- `completion_test.go` - Unit tests for command structure and script
content
Changes to `beacon-chain` and `validator`:
- Import `cmd.CompletionCommand("binary-name")` in the Commands slice
- Set `EnableBashCompletion: true` on the cli.App to activate
urfave/cli's `--generate-bash-completion` hidden flag
The shell scripts call the binary with `--generate-bash-completion`
appended to get context-aware suggestions. This means completions
automatically reflect the current binary's flags and commands.

`SlotIntervalTicker` was created in `prepareForkChoiceAtts` and in the
fork-choice attestation processing routine without ever calling `Done()`
when the service context was cancelled. Once the consuming goroutine
exits on `ctx.Done()`, the ticker keeps running and eventually blocks on
sending to its channel, leaving a leaked goroutine behind.
This change wires the lifetime of the `SlotIntervalTicker` to the
corresponding service contexts by calling `ticker.Done()` on
`ctx.Done()` in both call sites. This keeps the behaviour of the
routines unchanged while ensuring the ticker goroutines exit cleanly on
shutdown, consistent with how regular `SlotTicker` is handled elsewhere
in the codebase.

This PR uses the head state to validate data column in more places than
we currently do. When the parent state is from the previous epoch and is
the head (for example at slot 0) instead of replaying slot and doing an
epoch transition, we use the head state directly.
Another change is that instead of replaying until the parent state in
the case of a head miss, we only replay until the target checkpoint
state, which is more likely to be a checkpoint state in the epoch
boundary cache.

**What type of PR is this?**
Feature
**What does this PR do? Why is it needed?**
- upgrading go ethereum to 1.16.7
- enabling fulu e2e
- added new e2e field params and build option
- removes github.com/MariusVanDerWijden/FuzzyVM
v0.0.0-20240516070431-7828990cad7d and
github.com/MariusVanDerWijden/tx-fuzz v1.4.0
what changed
- e2e config on slots per epoch increased to match minimum 6->8 a 33%
increase in run time ( this is needed because field params only have
minimum presets and proposer look ahead feature uses it, so if it
doesn't match it fails)
- reduce presubmit epochs from 18 -> 10 and only run for electra -> fulu
- moves bellatrix -> fulu post merge test to post submit

This PR adds the logic to migrate to cold when the database has the
hdiff feature. The main difference is that the boundary states have to
have the right slot therefore they need to be advanced and aren't
necessarily the post-state of a given beacon block root.

Bug fix
**What does this PR do? Why is it needed?**
**Before this PR:**
When starting the node with the `--[semi-]supernode` flag with an
already existing DB, the new value of the earliest available slot was
set to the slot of the latest finalized checkpoint.
==> Between the latest finalized checkpoint and the slot where Prysm
starts to actually sync (the justified checkpoint) after the reboot,
Prysm advertises a higher `cgc` than it should.
**With this PR:**
If, at node start, the node needs to increase its `cgc`, then it uses
the latest justified checkpoint (+ 1) for the new `eas`.
**Which issues(s) does this PR fix?**
- https://github.com/OffchainLabs/prysm/issues/16066
**Example of a test case:**
1. Start the node with an empty DB, without any validator connected.
```
[2026-01-09 13:38:21.77] DEBUG db: Custody info earliestAvailableSlot=2145952 groupCount=4
```
2. Try:
```
curl http://localhost:3500/eth/v1/beacon/blobs/2145952 | jq
{
"message": "Not found: the node does not custody enough data columns to reconstruct blobs - please start the beacon node with the `--semi-supernode` flag to ensure this call to succeed",
"code": 404
}
```
==> This is expected, since `cgc=4 < 64`
3. After a few epochs, add a few validators (< 64):
```
[2026-01-09 13:43:21.77] DEBUG db: Custody info earliestAvailableSlot=2146066 groupCount=10
```
4. Try:
```
curl http://localhost:3500/eth/v1/beacon/blobs/2146066 | jq
{
"message": "Not found: the node does not custody enough data columns to reconstruct blobs - please start the beacon node with the `--semi-supernode` flag to ensure this call to succeed",
"code": 404
}
```
==> This is expected, since `cgc=10 < 64`
5. After a few epochs, restart the node:
```
[2026-01-09 13:46:44.09] DEBUG db: Custody info earliestAvailableSlot=2146066 groupCount=10
```
==> OK (No change)
6. Restart the node with the `--semi-supernode` flag.
```
[2026-01-09 13:49:26.14] DEBUG db: Custody info earliestAvailableSlot=2146049 groupCount=64
```
The `eas` goes backward which is expected, since the node restarts
syncing from the latest justified checkpoint, which in this case is
lower than the slot where we added validators during step `3.`.
Try:
```
curl http://localhost:3500/eth/v1/beacon/blobs/2146049 | jq
==> OK
```
The whole `eas/cgc` advertisement management should probably be
re-thinked, for example by using what the node actually has in its DB to
decide what `eas/cgc` should be advertised.
(With a particular attention to the full node case until
https://github.com/OffchainLabs/prysm/issues/16065 is fixed.)
However, this PR fixes the linked issue, so it's a good fix until a
deeper redesign is done.

Adds a feature flag `--enable-proposer-preprocessing` to verify
individual signatures in the block right before proposing to fallback to
empty fields in case of failure.
