# Vouch network > Vouch for or denounce accounts, and see the trust signals from your network. import VouchCardDemo from "../../../components/VouchCardDemo.svelte"; Vouching serves as a signal of trust to your circle. You can vouch or denounce users that you interact with. It is a signal of trust to your circle. Your circle can view vouch descisions made by you. Vouching on Tangled is inspired by the [vouch](https://github.com/mitchellh/vouch) project by Mitchell Hashimoto. Read the [blog post](https://blog.tangled.org/vouching/) to know more. ## Vouch or denounce Open a profile and select **Vouch**. Then select **Vouch** or **Denounce**. You can add an optional reason, up to 256 characters. When vouching for a user from the a PR submission, Tangled automatically adds the PR record to the vouch record's evidences list. ## The network Tangled collects vouch records from every account. It shows a "hat" on a profile at points of interaction: - issues and issue comments, and - pull requests and pull request comments. A green hat is a vouch. A red hat is a denouncement. A hat appears only in two cases: - you vouched for or denounced the account, or - an account you vouched for made a decision about it. Thus you see the decisions of your circle. Select the hat to see who made the decision. Only a vouch extends your circle: a denouncement does not add the account to your network. Two people can see different hats for the same account. ## The effects of vouching A vouch or a denouncement does not gate any permissions at the moment. It does not hide anyone's issues or pull requests. It shows a hat only. Use the hat to inform your decision. A denouncement has no consequence for the other account at this time. Vouching is simply used to build your trust network and inform your circle, actions are left up to the end user. :::caution Reasons and evidence are public data in your account. Anyone can read them, independent of any web app. Do not put private reports or personal information in them. :::
