I read the tor hsv3 specs and saw some parts considering load balancing.

=== 1.5. In more detail: Scaling to multiple hosts

This design is compatible with our current approaches for scaling 

hidden services. Specifically, hidden service operators can use onionbalance to achieve high availability between multiple nodes on the HSDir layer. Furthermore, operators can use proposal 255 to load balance their hidden services on the introduction layer. See [SCALING-REFS] for further discussions on this topic and alternative designs. === The reason for a maximum value of 20 is to give enough scalability to tools like OnionBalance to be able to load balance up to 120 servers (20 x 6 HSDirs) but also in order for the descriptor size to not overwhelmed hidden service directories with user defined values that could be gigantic. ===

So... can we benefit from this? Onionbalance seems to have been abandoned and prop255 seems to have stalled. Is there any effective way to properly load balance hsv3?

Hello,

we are currently developing onionbalance for v3 onions. Please see https://trac.torproject.org/projects/tor/ticket/26768 for more details.

It should be out at some point around Christmas: consider it as our Christmas gift from us to you!

Until then you can still do naive onion load balancing by just configuring a bunch of onion services with the same private key, so that they race each other. That would still work with v3s.
