We store a blockheight at which point a private key is created, allowing
us to skip merkle checks before that time.
This was was tricky for a not yet synched wallet because its blockchain
was stuck at height zero.
Causing us to sync everything anyway.
Now we store the timestamp of wallet create instead, until the time that
the blockchain is synched. After that we resolve the block that we need
to start sync from based on that timestamp.
For each transaction allow to click on it and show lots of further
details about it.
This also fixes various bugs and adds some basic helper methods in
various places.
The QML is barely functional, getting the right data exposed was the
only goal today.
We wait until the chain is synched and then we check for and broadcast
unconfirmed transactions.
This essentially means that every single block we receive will trigger
this code. In BCH I think that is just fine since all we really do is
send an INV.
When a transaction is received by the p2pnet layer via a simple INV/
GetData we now process this and properly lock the outputs it spent to
avoid creating double spending transactions.
One task is left: properly recognize when a mined transaction
invalidates another transaction (like an unconfirmed one) and update the
datastructures.
This provides code for creating the transaction, selecting the UTXOs and
signing the transaction.
Essentially everything except the handling of final tx (like sending it
to a peer).
For maintainability the pair of tx-index/output-index are now stored in
a simple class.
Additionally the calls to the privacyFilter have been upgraded to follow
the API fix in Flowee the Hub.
This is clearly beta-level quality, it won't lose your money, but
kittens can be killed if you use this in production! Don't do that!
This payment client uses the proper P2P client and does not require
any additional indexing services and therefor is very much geared
towards the most private it can be with SPV, while staying scalable and
nible.
The only GUI available right now is for the desktop, it should be pretty
simple to re-do a nice GUI for some mobile or similar form-factors.
That is one area that QML simply rocks in.
