libdohj VS dogecoin-spv-node

#2758 that removes a potential spam problem in the p2p protocol needs testing with libdohj to make sure that we don’t accidentally exclude wallets built upon that library from the network.

The technical problem to solve is to have a means to translate implicit on-chain transaction events to webhook calls (tx received, tx confirmed, # confirmations, tx got reorg'd). For my pilot, I used block.io because /u/kindoge has made a very reliable webhook mechanism so I didn't have to code that from scratch. If you need a full sovereign solution, I think that besides doing it on Dogecoin Core, something can be built into dogecoin-spv-node (js) or create a custom thing with libdohj (java) (perhaps until /u/xanimo-net is further along with libdogecoin and gives you a php sdk 😁).

Pruning works well, you don't need any patches for that and can just use 1.14.5. You can also use dogecoin-node-spv or build something with libdohj for an spv client.

You may want to take a look at https://github.com/dogecoin/libdohj for java / android.

I've not had time to do much with it recently, but is https://github.com/dogecoin/libdohj the sort of thing you're looking for to get started?

Multidoge is depreciated though, someone should build a new light wallet based on https://github.com/dogecoin/libdohj - that's a nice starter project because that offers a lot of the harder crypto already solved.

Libdohj the backbone for many Java implementations of Dogecoin wallets, based from this. Shows not only work but a full pushed update less than two weeks ago.

There currently is the cltv-spillman-style payment channel implementation but that is a unidirectional, for-purpose channel, so it's not an L2. Other than that I haven't heard of a timelock based L2. I have some designs for a timelock based sidechain though, but that has nothing to do with L2.
