# A Note on Determinism The logic for blockchain transaction processing must be deterministic. If the application logic was not made to be deterministic a consensus would not be reached among the Tendermint Core replica nodes. Solidity on Ethereum is a great language of choice for blockchain applications because, among other reasons, it is a completely deterministic programming language. However, it is also possible to create deterministic applications using existing popular languages like Java, C++, Python, or Go. Game programmers and blockchain developers are already familiar with creating deterministic programs by avoiding sources of non-determinism such as: * random number generators (without deterministic seeding) * race conditions on threads (or avoiding threads altogether) * system clocks * uninitialised memory (in unsafe programming languages like C or C++) * floating point arithmetic * language features that are random (e.g. map iterations in Go) While programmers can avoid non-determinism by being careful it is also possible to create a special linter or static analyser for each language to check for determinism. In future, we may work with partners to create such tools. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.emoney.network/tendermint-and-evmos/a-note-on-determinism.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
