This paper surveys recent work on applying analysis and transformation techniques that
originate in the field of constraint logic programming (CLP) to the problem of verifying …

Decentralized Finance (DeFi) is emerging as a peer-to-peer financial ecosystem, enabling
participants to trade products on a permissionless blockchain. Built on blockchain and smart …

Smart contracts facilitate the execution of programmable code on a blockchain. The cost for
executing smart contract code is metered using gas-the exact amount of which is based on …

Users must pay a fee depending on resource consumption when using smart contracts on
the Ethereum blockchain. As even the most basic operations cost several dollars under …

Smart contracts deployed to the Ethereum blockchain hold billions of dollars worth of assets.
Ethereum currently represents the most widely used smart contract platform. It is the second …

Recurrence equations have played a central role in static cost analysis, where they can be
viewed as abstractions of programs and used to infer resource usage information without …

Context-sensitive global analysis of large code bases can be expensive, which can make its
use impractical during software development. However, there are many situations in which …

Nontermination is an unwanted program property for some software systems, and a safety
property for other systems. In either case, automated discovery of preconditions for …

Assertion checking is an invaluable programmer's tool for finding many classes of errors or
verifying their absence in dynamic languages such as Prolog. For Prolog programmers, this …

The Ethereum blockchain has a\emph {gas system} that associates operations with a cost in
gas units. Two central concepts of this system are the\emph {gas limit} assigned by the …
