Summary for December 2018
We’ve been taking a break for the past two months while working on a website upgrade. Since we did not cover news in that time, we decided to make a series of recap articles covering the last two months, starting with news related Bitcoin Core and going through Lightning Network and its related updates.
Data Piggybacking Within the Payment Preimage for Offline Payments in Wallets
Piggybacking information within payment_preimage is a suggestion by developer Jose Femenias, it is used to enable sharing a common secret seed between an offline device and an online LN node, both the devices calculate the same per_transaction_secret, the node encrypts the PIN within the payment_preimage and then when the LN wallet receives the payment_preimage it decrypts it showing the PIN, this is provided as proof of payment to the offline device.
