+`validatorsAccumulator` is a Merkle tree accumulator that contains the public keys of validators and their corresponding Eth1 deposit indexes.

+In the deposit function, each validator's public key and their Eth1 deposit index are packed together and hashed to form a node. This node represents the validator in the Merkle tree.
+
+The node is then inserted into the Merkle tree at the appropriate level, based on the current number of validators. The path to insert the node is determined using the binary representation of the total validator count. The leftmost branch is taken for every 0, and the rightmost branch for every 1.
+
+The get_validators_accumulator function calculates and returns the Merkle root of the validatorsAccumulator. This root is a single hash that effectively represents all the validators in the accumulator.
