7.7 Off-path Payment Privacy of Bitcoin Lightning Network || Seres Istvan

Seres Istvan [@Istvan_A_Seres] says that nodes who are not in the route of a payment through the Bitcoin Lightning Network should learn no information that this payment is happening, or how much bitcoin is being sent. The attacker can break this privacy guarantee by finding out the balances of most channels in the network multiple times, and calculating the differences of each snapshot. https://arxiv.org/pdf/2003.12470.pdf https://arxiv.org/pdf/2007.00764.pdf https://arxiv.org/pdf/2004.00333.pdf https://arxiv.org/pdf/1911.09432.pdf https://arxiv.org/pdf/2102.09256.pdf https://arxiv.org/pdf/2006.12143.pdf
