EIP-4788 exposes the beacon root to smart contracts, but smart contracts using it need to be redeployed / upgraded whenever the indexing changes during a fork, even if that fork does not touch any used functionality. This problem expands further to bridges on other blockchains, or even into wallet apps on a phone that verify data from the beacon chain instead of trusting the server. It is quite unrealistic to expect such projects to all align their release cadence with Ethereum's forks. EIP-7688 fixes this by defining forward compatibility for beacon chain data structures. Electra `Profile` retain their Merkleization even when rebased to `StableContainer` definitions from future forks, enabling decentralized protocols to drop the requirement for trusted parties to periodically upgrade beacon state proof verifiers.
