@wemeetagain Does this issue require any changes in our case? It just adds a `uint32` casting ```python variable_offsets = [serialize(uint32(sum(fixed_lengths + variable_lengths[:i]))) for i in range(len(value))] ```

The cause has been traced back to the SubTree WeakRef - nodejs/node issue (closed) https://github.com/nodejs/node/issues/39902 - v8 issue https://bugs.chromium.org/p/v8/issues/detail?id=12145

With a steep decline of priority over time, should this be implemented? If so, it this mono-repo the right place or should it be a separate project?

I propose to add constructor options to composite types so you can choose not to return a Tree (*using `shouldNotReturnSubTree` for clarity, but we should use a better name*) ```ts...

I've done some extra analysis of the performance of hashTreeRoot. Commenting to link the issues https://github.com/ChainSafe/lodestar/issues/2206 The approach is to compare us with Lighthouse, and apparently our hashing function is...

@hujw77 thank you so much for the contribution! Could you add tests to prove correct logic?
