Audit standards help establish a benchmark for the audit process, ensuring consistency and reliability in the methods used to evaluate the financial statements and practices of a company. These standards are often set by recognized authorities such as the International Auditing and Assurance Standards Board (IAASB) and the American Institute of Certified Public Accountants (AICPA). They cover areas such as audit planning, risk assessment, evidence collection, and reporting. In the context of blockchain and web3 systems, these standards are crucial for evaluating the integrity and security of smart contracts, decentralized applications, and financial transactions.
