摘要

智能合约是在区块链中运行的自动执行程序,允许在没有中间人的情况下进行分散存储和执行。链上执行是昂贵的,矿工根据协议中定义的成本模型对分布式执行收取费用。特别是,交易具有很高的固定成本。在本文中,我们介绍了MultiCall,这是一个解释器,通过在一个交易中模拟来自多个用户的交易序列来降低智能合约执行的成本。我们已经将MultiCall实现并集成到以太坊中。我们的评估表明,与单独发送交易的标准方法相比,使用MultiCall可以节省56.8%到98.9%的固定每交易成本。

MultiCall: A Transaction-batching Interpreter for Ethereum
Smart contracts are self-executing programs running in the blockchain allowing for decentralised storage and execution without a middleman. On-chain execution is expensive, with miners charging fees for distributed execution according to a cost model defined in the protocol. In particular, transactions have a high fixed cost. In this paper we present MultiCall, an interpreter that reduces the cost of smart contract execution by emulating sequences of transactions from multiple users in one transaction. We have implemented and integrated MultiCall into Ethereum. Our evaluation shows that using MultiCall provides a saving between 56.8% and 98.9% of the fixed per-transaction cost compared to the standard approach of sending transactions individually.
