Hello ZmnSCPxj,
Such a system will have to be publicly advertised, in the same way we
see centralized cryptocurrency staking shops buying ads all over the
place. That's how they'll make retail hodlers aware that renting out
your coins in this way is possible. If JoinMarket/Teleport users notice
such ads appearing then we could change the taker code to remove the
intermediate certificate keypair, and have the fidelity bond UTXO key
sign the endpoint (IRC nickname or onion hostname) directly. This
removes the possibility of fidelity bonds in cold storage. It would have
to be done for privacy, and it wouldn't be too bad. Right now there's no
cold storage solution for fidelity bonds yet JoinMarket has about 600
bitcoins locked up and advertised, which must be all on hot wallets.
Best,
CB

Good morning Chris,
Hello ZmnSCPxj,
Renting out fidelity bonds is an interesting idea. It might happen in
the situation where a hodler wants to generate yield but doesn't want
the hassle of running a full node and yield generator. A big downside of
it is that the yield generator income is random while the rent paid is a
fixed cost, so there's a chance that the income won't cover the rent.
The fact that *renting* is at all possible suggests to me that the following
situation *could* arise:
* A market of lessors arises.
* A surveillor creates multiple identities.
* Each fake identity rents separately from multiple lessors.
* Surveillor gets privacy data by paying out rent money to the lessor market.
In defiads, I and Tamas pretty much concluded that rental would happen
inevitably.
One could say that defiads was a kind of fidelity bond system.
Our solution for defiads was to prioritize propagating advertisements (roughly
equivalent to the certificates in your system, I think) with larger bonded
values * min(bonded_time, 1 year).
However, do note that we did not intend defiads to be used for
privacy-sensitive applications like JoinMarket/Teleport.
