sha256 works in blocks, each is 64 bytes so perhaps it's more meaningful to reflect that for also with holesky, there are 1.7M validators. For every 8 deposits we have to reallocate the whole 1.7M * 8 bytes = 13.6MB for Update:

I left a few comments but I think this PR really needs to be reviewed by @wemeetagain

It might be helpful to break out a helper function so its clear why this is happening everywhere.
export function getPaddedByte32Count(buf: ArrayBuffer): number {
return Math.ceil(buf.length / 32);
}
export function getPaddedByte64Count(buf: ArrayBuffer): number {
return Math.ceil(buf.length / 64);
}This reverts commit 15cf649.

is this comment correct? it looks like hashTreeRootInto is filling all 32 bytes

I'd remove that comment @nazarhussain . I remember I tried allocUnsafe() at some points and got "Invalid state root" issue. If we want to apply it, need to audit carefully an apply to other places as well
