# High-computational and Storage Efficiency

A smart contract can carry out complex computations like verifying a block header with hundreds of signatures or storing a few hundred GB of data on a chain, all at a very affordable cost, which is simply impossible on any other blockchains. This is why Omnity can implement the world's first on-chain Bitcoin token indexer, which facilitates transferring Bitcoin tokens to other blockchains in a fully trustless way.
