I notice that most users with open offers seem to have longer, V3 .onion addresses, but a few have short V2 .onion addresses. Is there an explanation for this? Are the shorter onion addresses more “suspicious” (ex., using an older version of Bisq or some kind of hacked version)? Or, are they more “trustworthy” (ex., because they’ve maintained a Bisq account for a long time)? I’m just curious - thanks! ---

You can find more information on that topic in this thread and wiki page: > [@Tor v2 Addresses](https://bisq.community/t/tor-v2-addresses/10503): > > In October 2021 support for tor v2 address will end ([Onion Service version 2 deprecation timeline | Tor Blog](https://blog.torproject.org/v2-deprecation-timeline)). Is there a possibility to migrate to a new v3 address without stopping all trades and offers at the same time? According to this wiki page [Local reputation - Bisq Wiki](https://bisq.wiki/Local_reputation) an existing onion key should not be deleted while having open offers etc. It would be nice to be able to create new offers using already a new v3 address while slowly using up all old v2 based offers. A migration as smo… [https://bisq.wiki/Changing\_your\_onion\_address](https://bisq.wiki/Changing_your_onion_address) Tor v2. will be disabled this year. ---
