Security of smart contracts written in the Solidity programming language

Coding smart contracts in the Solidity programming language represents a special challenge, as the specifics of blockchain technology require the use of unconventional programming patterns. Any bugs and security flaws written in the code are visible to everyone, as the source code of smart contracts is public viewable. From the security point of view, it is therefore recommended that the Solidity programmer should have a good knowledge of established programming design patterns. That allows him or her to write functional programming code and reduces the possibility of making mistakes.
