now instead of saving all roots, we'll just save serialized snapshot periodically. Something like: const treeSnapshot = depositRootTree.toSnapshot(depositCount);
const depositSnapshot = {
finalized: treeSnapshot.finalized,
depositRoot: treeSnapshot.root,
depositCount: treeSnapshot.count,
executionBlockHash,
executionBlockHeight,
};
db.put(executionBlockHeight, depositSnapshot);upon restart we download snapshot from const depositRootTree = DepositDataRootPartialList.toPartialViewDU({
finalized: snapshot.finalized,
root: snapshot.depositRoot,
count: snapshot.depositCount,
});then the partial tree grows from there similar to the current full tree |

Implement snapshot apis for eip-4881
Description
PartialListCompositeTypetype along with ViewDU (and no View since we lacks a lot of methods there and dont maintain it anymore)toPartialViewDU()api as the entry pointtoSnapshot, fromSnapshotapisDepositDataRootPartialList = new PartialListCompositeType(Root, 2 ** DEPOSIT_CONTRACT_TREE_DEPTH);depositRootTree = DepositDataRootPartialList.toPartialViewDU(snapshot)Closes #293
a candidate to replace #377
