Maybe I'm being too much of a Spok here, @shadders , but this sentence's semantics beg for a question: "SPV Channels CE (for “community edition”) allows asynchronous encrypted messaging between participants, even when there’s no direct connection between them (e.g. one may be offline)." Does "direct cxn between them" mean: 1) The wallets can talk to each other, via something like NFC phone-to-phone, but niether can talk to the internet (no WIFI or LTE)? 2) One wallet can access the internet while the other cannot? 3) The two wallets cannot talk via NFC, but one of them has internet access? 4) Other? Seems like if both wallets are SPV and using NFC, and niether has internet connection, money can STILL be confidently exchanged so long as the receiver trusts his SPV verfication and the inputs are sufficiently deep from the blockchain tip, no? But to do this, the sender would need to send the merkel branch hashes of the inputs, along with the transaction, yes? source: https://coingeek.com/true-p2p-and-spv-released-on-bitcoin/
