I'm pleased to announce the release of bitcoinj 0.16.3, a bug fix and
maintenance update to the Java implementation of the Bitcoin protocol.
This release fixes a bug that prevents blockchain sync of mainnet blocks

For a thorough list of changes, have a look at the release
If "wallets are loaded with 13k addresses" means you derived 13k
addresses from the wallet, that's really a lot! I doubt we have ever
tested it with that many addresses. Under normal usage, one address
would be created for each incoming payment (for receiving) and one
address for most outgoing

The callback should fire immediately after bitcoinj first learns of an
incoming transaction, either by unconfirmed broadcast or by block (if it
missed the broadcast).

Generally it's not a good idea trying to derive a "from address".
Your code can only work in very specific cases (inputs spending P2PKH
outputs).
You should assert that chunks.size() == 2.
Also the example transaction is a BCH transaction. I'm not sure how
similar BCH is to Bitcoin these days
Half of your code example has nothing to do with bitcoinj. And on the
other hand, your "resync" code is missing.
Can you post the logfile (console output) and a wallet.toString() from

Have a look at the KeyChainGroupStructure class. You can define the

Regarding your first question: Bitcoinj has a CoinSelector interface you
can implement. The defaut implementation always picks the oldest coins

It's a limitation of the Bitcoin protocol. The fee is not an explicit
data field. To calculate the fee of a transaction, you need to know the
values of all inputs and outputs. And input values are not explicit
fields either; you need to know their connected outputs and use their value.

That is because the fee is defined as the difference of all input values
and all output values. And the Bitcoin protocol doesn't actually have

terms of security and usability so generally you're advised not to this.
If you want to move value, use a Bitcoin transaction.

Master is on 25.1-android already.

The Wallet class supports you with that. See the examples and/or the
WalletTool's 'send' implementation.

I have a version of Bitcoin Wallet that runs on master. So far I didn't
encounter any problems, but of course my testing is limited.
Yes, if no one objects my plan is to branch as soon everything that's
needed for receiving and sending to/from segwit native addresses is
implemented. We should
The stall messages are just a symptom. For finding the cause have a look
at the logfile of both bitcoinj and Bitcoin Core.

For the archive: this is now fixed on master, by specifying source

For years, we've been using SpongyCastle as a replacement for

BouncyCastle version with Android, which would clash with a BC castle

I'm not sure if anyone has ever done it. Are there any HSMs that can do
the BIP32 derivation of private keys? Trezor and its cousins are
probably the best bets, as they're designed for Bitcoin.
On master there is already the ability to derive from other paths if
needed. That should solve your

After importing a previously unknown key, you need to rescan the whole
blockchain for any UTXOs that might be relevant. Only after that is
finished you can prepare and sign a spending transaction. That's the
decentralized way to do it.
Alternatively, you could query an external service like a
