Much attention has been paid in recent years to the use of smart contracts. A smart contract is a transaction protocol that executes the terms of an agreement. Ethereum is a widely used platform for executing smart contracts, defined by using a Turing-complete language. Various studies have been performed in order to analyse smart contract data from different perspectives. In our study we gather a wide range of verified smart contracts written by using the Solidity language and we analyse their code. A similar study is carried out on Solidity compilers. The aim of our investigation is the identification of the smart contract functionalities, i.e. opcodes, that play a crucial role in practice, and single out those functionalities that are not practically relevant.

Abstract
Much attention has been paid in recent years to the use of smart contracts. A smart contract is a transaction protocol that executes the terms of an agreement. Ethereum is a widely used platform for executing smart contracts, defined by using a Turing-complete language. Various studies have been performed in order to analyse smart contract data from different perspectives. In our study we gather a wide range of verified smart contracts written by using the Solidity language and we analyse their code. A similar study is carried out on Solidity compilers. The aim of our investigation is the identification of the smart contract functionalities, i.e. opcodes, that play a crucial role in practice, and single out those functionalities that are not practically relevant.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
