### Describe the bug After `mev-boost` returns execution payload, it took ~1.5s to compute state root ``` Jun-03 22:01:24.079[chain] ^[[36mverbose^[[39m: Produced beacon block body fork=deneb, blockType=Blinded, slot=9219005, attestations=128, deposits=0, voluntaryExits=0,...

ViewDU container rebinds node with read-only operations

**Describe the bug** Consider this unit test here in #378 ```typescript it("should not recompute hashTreeRoot() when no fields is changed", () => { const root = state.hashTreeRoot(); // this causes...

fix: single state tree at start up

2

**Motivation** - we deserialize states 2 times to 2 separate tree: one for db state and one for ws state, and each `hashTreeRoot()` call takes ~24s of blocking time at...

fix: improve performance of getExpectedWithdrawals

1

**Motivation** - improve performance of getExpectedWithdrawals() **Description** - for EIP-7002 withdrawals, only call `getAllReadonly()` conditionally due to its big length limit - for capella withdrawals, improve performance by embedding logics...

feat: consume new ssz batch hash branch

3

**Motivation** - reduce `hash_tree_root` time in lodestar, especially at epoch transition time - this leverage the new [hashtree](https://github.com/ChainSafe/hashtree-js) which and new as-sha256 which support batch hash api **Description** - consume...

Use single state tree at startup

### Problem description Right now if user provides a `checkpointState` or `checkpointSyncUrl` we'll deserialize states to 2 separate trees: one with the last state stored in db and the other...

fix: improve regen state

3

**Motivation** - improve regen state - more metrics when regen state **Description** - most of the time to regen state is due to loading block from db. At this time...

feat: archive state using BufferPool if provided

2

**Motivation** - When n-historical state flag is lived, we have a BufferPool. We should use it to archive state better - It's also a prerequisite for [state-diff PR](https://github.com/ChainSafe/lodestar/pull/7005) **Description** -...
