This issue tracker is only for technical issues related to Bitcoin Core. General bitcoin questions and/or support requests are best directed to the [Bitcoin StackExchange](https://bitcoin.stackexchange.com). For reporting security issues, please read instructions at [https://bitcoincore.org/en/contact/](https://bitcoincore.org/en/contact/). If the node is "stuck" during sync or giving "block checksum mismatch" errors, please ensure your hardware is stable by running memtest and observe CPU temperature with a load-test tool such as linpack before creating an issue! ### Describe the issue #### What behavior did you expect? #### What was the actual behavior (provide screenshots if the issue is GUI-related)? #### How reliably can you reproduce the issue, what are the steps to do so? ### What version of Bitcoin Core are you using, where did you get it (website, self-compiled, etc)? ### What type of machine are you observing the error on (OS/CPU and disk type)? ### Any extra information that might be useful in the debugging process. This is normally the contents of a `debug.log` or `config.log` file. Raw text or a link to a pastebin type site are preferred.
