Smart Contracts News TLDR / Table of Contents
- GitHub is where people build software. More than 28 million people use GitHub to discover, fork, and contribute to over 80 million projects.
- EVM version, target EVM version, gas estimator reports, open source community, regular function calls
- Security Vulnerabilities in Smart Contracts – Schneier on Security
- smart contracts, trace vulnerabilities, smart contract, stateful executable objects, real exploits
- Smart Contracts, Explained
- Everything you wanted to know about smart contracts. | Explained | Cointelegraph
- smart contracts, smart contract, appropriate environment, main principles, Blockchain technology
- Also, the gas estimator reports different costs for the opcodes depending on the version and thus the optimizer might generate different code.
- We especially thank all our open source community contributors: – – This ensures that functions marked as or (previously ) cannot modify the state.
- This is especially important if you call unknown code via a generic interface and you cannot be sure whether the function modifies the state or not.
- Currently, the stack slot reserved for the variable still spans the whole function, but this is planned to be improved for the next release.
- We present a new systematic characterization of a class of trace vulnerabilities, which result from analyzing multiple invocations of a contract over its lifetime.
- We focus attention on three example properties of such trace vulnerabilities: finding contracts that either lock funds indefinitely, leak them carelessly to arbitrary users, or can be killed by anyone.
- We implemented MAIAN, the first tool for precisely specifying and reasoning about trace properties, which employs inter-procedural symbolic analysis and concrete validator for exhibiting real exploits.
- On a subset of 3,759 contracts which we sampled for concrete validation and manual analysis, we reproduce real exploits at a true positive rate of 89%, yielding exploits for 3,686 contracts.
- Our tool finds exploits for the infamous Parity bug that indirectly locked 200 million dollars worth in Ether, which previous analyses failed to capture.
- A lot has changed since Blockchain technology emerged.
- Bitcoin laid the basis for contracting on the Blockchain.
