Lorenzo, founder of Bitcoin Scaling Solution Fractal Bitcoin, said in an X post in response to a previous tweet by StarkWare Eco-Head about Fractal Bitcoin or the existence of security issues: "Thanks for discovering these vulnerabilities, the Docker repository (which contains bitcoin.conf file) is only for internal quick testing purposes. It should have been removed during the last testnet last month. We removed the bitcoin.conf file from the fractal-docker directory. If you want to use this Docker setup for quick testing, please generate your own configuration file. Please note that the latest release version is still v0.2.1 and there are no changes". Previously, StarkWare's ecological director wrote on the X platform that there may be security issues with Fractal Bitcoin.
