MultiCall: an interpreter implemented on the Ethereum Virtual Machine

Abstract

Cryptocurrency protocols such as Bitcoin and Ethereum provide distributed ledgers, decentralized databases which can be used to make censorship-proof payments without a trusted intermediary. The computation performed to update the ledger is performed redundantly across thousands of servers and is therefore expensive. Ethereum additionally supports Turing complete programs stored in the ledger; they can be used to retrofit the protocol with new capabilities and optimizations. The following thesis presents the MultiCall interpreter, a smart contract implemented on the Ethereum blockchain which is capable of significantly reducing the cost of payments by emulating multiple transactions with a single invocation of the interpreter.
