Episode notes
Seres Istvan [@Istvan_A_Seres] lays out that the capacity of a Bitcoin Lightning Network payment channel is known by everyone, but the balance of which peer owns how much bitcoin inside the channel should be obfuscated. But an adversary can discover the balance by attacking with channel probing, to send many payments at different values, seeing at what balances they fail to route.
