The Election contract is responsible for managing the validator elections on the TON blockchain.

The reason why the contract's balance may be greater than the total stake of all validators combined is because the stake of each validator is divided into two halves, and only one half is used during the current validation round.

In order to participate in the next round, validators must make a new stake before it begins, while their previous stake is still locked.

As a result, the Election contract may hold a significant amount of locked stakes from previous rounds, leading to a higher balance than the total stake of active validators.
