I'm trying to use bchwallet (https://github.com/gcash/bchwallet) in SPV mode, as described in this article: https://medium.com/@bchd.cash/announcing-neutrino-wallet-for-bitcoin-cash-eb7a85a49c0e
I can see that the wallet is finding a bunch of peers and trying to download block headers from those peers. However, it appears that each peer gets immediately dropped once the wallet starts trying to download block headers. Once all the discovered peers are dropped, the wallet simply stalls.
I tried manually adding a specific peer by using the --addpeer option to add bchd.fountainhead.cash. When I did this, rather than stalling, I could see that the wallet kept trying to reconnect to that one peer, but the peer was immediately lost each time.
Has anyone gotten bchwallet to work in SPV mode? Any chance of some pointers on what I'm doing wrong?
Command I run:
./bchwallet -u blahblahuser -P blahblahpassword --usespv --rpclisten=0.0.0.0:8332 --noinitialload --addpeer=bchd.fountainhead.cash
Sample output:
