Free New Tool for Building Blockchain Skills

Blockchain CTF helps pros build skills with simulations.

Blockchain is understood to be an inherently secure technology, but that doesn't mean every implementation of blockchain is secure. A new tool, Blockchain CTF, can help train software developers, security professionals, and blockchain experts to design and implement more secure blockchain applications.

Blockchain CTF (which stands for "capture the flag") is a simulator developed by Security Innovation, a company that provides security training, assessment, and consulting. Blockchain CTF is being released as a free resource for members of the security and blockchain communities.

With Blockchain CTF, participants see a series of vulnerable smart contracts and decentralized apps (DApps) in situations that range from initial coin offerings to open source lotteries. Participants are challenged to find and exploit the vulnerabilities and, in doing so, win points for placement on a leaderboard.

Within the simulations, Security Innovation provides tips and hints aimed at helping participants gain knowledge in developing and testing smart contracts and DApps. The platform is implemented as a client-side DApp on the Ethereum Testnet Blockchain, with states managed by the Ropsten Testnet Blockchain.
