| JoinMarket yield generators earn money on an unpredictable basis. It's worth calculating | |
| the equivalent interest rate as if joinmarket was a savings account. | |
| We can make a model of a bank account that takes deposits and withdrawals at any time and | |
| where the balance accumulates interest, then the parameters from a JoinMarket yield-generator | |
| wallet can be inputted to obtain the equivalent interest rate. | |
| We know that the present value of a bank account (P) grows to the future value (F) determined | |
| by the interest rate per unit time (r) and time (t) | |

JoinMarket release 0.2.0 ameliorates this snooping attack. It is a protocol-breaking change so everyone must update which we anticipate may take some time.
https://github.com/JoinMarket-Org/joinmarket/blob/master/doc/release-notes-0.2.0.md
Looks like enough people have updated and there's plenty of liquidity now.

A single JoinMarket coinjoin often doesn't hide which inputs belong to the maker(s) and which belong to the taker. This is because the coinjoin fee is included on-chain.
To tell apart takers' inputs from makers' inputs, subset matching can be used. The taker's subset is

Lightweight wallets are ones which are not full nodes. Lots of people use them because full nodes are costly: they cost time to setup/synchronize, education, disk space, bandwidth, RAM and a few other resources.
