When using checkpoints, the November 13 DAA will fail. This was resolved with #18 on cash-0.14 with https://github.com/bitcoinj-cash/bitcoinj/pull/18/files#diff-ef262b65e6add81fc5f71fd7a4e2d82cR242
on getPrev(), check for null and if it is null throw BlockStoreException.
By way of reminder, checkpoints allow the app to start syncing the blockchain at arbitrary block heights instead of starting from block 0.

I propose to remove the BTC Bitcoinj branches from this repo because they cause confusion. If we need to merge changes from the BTC Bitcoinj into this repo, this can be done using a local git, pulling the necessary commits across.
The affected branches would be: "master", "release-0.14", and "segwit".
Any thoughts?
I have noticed sometimes the MultiplexingDiscovery is not able to find peers. This issue occurs randomly and is very confusing for the user: Can't see the balance increasing after send some funds.

I use the above code to import the wallet, get the balance of the wallet, but the balance of the wallet is empty, and the address of this wallet is not 0 in the other purse tools. Why
I'm experiencing problems with the tx.getFee() method. Some times works fine but others just returns 0.0 when actually the fees are higher than that.
I haven't been able to find a pattern with the transactions causing the issues. Some examples:
Any hypothesis about what could be causing the this random issue?

how can i sign bch txs offline with this library？
Can you give me a demo？
Now it's impossible to use this module with bitcoinj in one project due the package name conflict, this is very inconvenient.

In JDK 9 the Cleaner the sun.mic.Cleaner class was removed.
use JDK 8 or lower.
Taken from javadoc of org.bitcoinj.store.WindowsMMapHack:
This class knows how to force an mmap'd ByteBuffer to reliquish its file handles before it becomes garbage collected,
by exploiting implementation details of the HotSpot JVM implementation.This is required on Windows because otherwise an attempt to delete a file that is still mmapped will fail. This can happen when a user requests a "restore from seed" function, which involves deleting and recreating the chain file. At some point we should stop using mmap in SPVBlockStore and we can then delete this class.
It is a separate class to avoid hitting unknown imports when running on other JVMs
The specific java bug is marked as a won't fix
Suggest we look at alternatives to MappedByteBuffers or an alternative (API supported) means of explicitly releasing the memory mapping.
As you know, Bitcoin Cash dropped the legacy RBF protocol in order to simplify 0-conf payments. Still not 100% secure since a rival could try different attacks that I personally consider very unlikely, but just my opinion (we can discuss about it if required).
The different Bitcoin Cash wallet, should consider this feature to provide the best user experience. In the future, we should stop using "confirmations" as a common word for payments. To go mainstream we need people and merchants to stop caring about confirmations, they just need to pay done. Does people care about the technical details when they pay using Visa? Not at all.
Since we have a technology that allow us to work this way, I think we should start taking the most from Bitcoin Cash. If we all are integrating 0-conf in our wallets, add this feature to the Bitcoinj-cash library is the way to go: each wallet don't need to reinvent the wheel + we standardise the algorithm to do it.
Just following some comments from Satoshi: https://bitcointalk.org/index.php?topic=423.msg3819#msg3819 and https://bitcointalk.org/index.php?topic=532.msg6306#msg6306.
In the big picture we need to:
As far as I understand, this is could be an algorithm to process 0-conf payments, opened to changes, for sure:
Notice any of this parameters could be tuned, depending of the considerations of each wallet. If this is becoming standard, should be flexible enough.
Pending question: what to do in case we find a double-spend after we broadcast?
As the original bitcoinj project works over Bitcoin Core, and it includes the RBF feature obviously it doesn't consider any of the previous points.
Correct me if I'm wrong but when you include a broadcast transaction listener, it's only invoked if the transaction is accepted by a node, but you can't notice if any node rejects it. This node rejection message remains totally hidden, what makes the previous algorithm a little bit tricky. https://github.com/bitcoinj-cash/bitcoinj/blob/cash-0.14/core/src/main/java/org/bitcoinj/core/TransactionBroadcast.java#L91
Provide a solution to have all the required events over the transactions is a must to implement the a 0-conf algorithm.
TransactionBroadcaster https://github.com/bitcoinj-cash/bitcoinj/blob/cash-0.14/core/src/main/java/org/bitcoinj/core/TransactionBroadcaster.java that performs this new logic.broadcastTransaction method to include a kind of listener to notify the response:public TransactionBroadcast broadcastTransaction(Transaction tx, int minConnections)
public TransactionBroadcast broadcastTransaction(Transaction tx, int minConnections, BroadcastTransactionListener listener)
BroadcastTransactionListener. For instance: public interface BroadcastTransactionListener{
void onBroadcastSuccess(Transaction tx);
void onDoubleSpendReceived(Transaction broadcasted, Transaction received);
void onProgress(int totalBroadcasts, int target);
}
What is your view for this? Many points to discuss, so please just let out any insight or comment you have.

Hello
I've developing some bitcoin cash wallet app on android with this bitcoinj.cash library.
I've some problems with restoring wallet from seed.
I restored wallet I had created in other wallet app (handcash) and there are some BCH.
but restored wallet shows always has a zero balance.
If I send some bch to this newly restored wallet, It will be displayed as successful and it will be displayed with another wallet app(handcash) that I already have.
The newly restored wallet only shows transactions that occurred after it was restored....
how can I fix this issue?
here is the code that i've tried
NetworkParameters parameters = null;
if(walletAppKit == null || !walletAppKit.isRunning()) {
if(BuildConfig.MAINNET)
parameters = MainNetParams.get();
else
parameters = TestNet3Params.get();
File walletDir = getFilesDir();
walletAppKit = new WalletAppKit(parameters, walletDir, WALLET_NAME) {
@Override
protected void onSetupCompleted() {
wallet().allowSpendingUnconfirmedTransactions();;
wallet().addCoinsReceivedEventListener(BitcoinService.this);
wallet().addCoinsSentEventListener(BitcoinService.this);
walletAppKit.setDownloadListener(new DownloadProgressTracker() {
@Override
protected void progress(double pct, int blocksSoFar, Date date) {
super.progress(pct, blocksSoFar, date);
// progressing....
}
});
}
};
walletAppKit.setBlockingStartup(false);
walletAppKit.setAutoSave(true);
walletAppKit.setUserAgent(getString(R.string.app_name), BuildConfig.VERSION_NAME);
if (mnemonicCode != null) {
try {
DeterministicSeed seed = new DeterministicSeed(mnemonicCode, null, "", MnemonicCode.BIP39_STANDARDISATION_TIME_SECS);
walletAppKit.restoreWalletFromSeed(seed);
} catch (UnreadableWalletException e) {
e.printStackTrace();
}
}
}
walletAppKit.startAsync();
}

Account balances are adequate, and transfers always indicate insufficient balance. The balance found through the import wallet is also correct. Why?
org.bitcoinj.core.InsufficientMoneyException: Insufficient money, missing 0.01001546 BCH
The payment channel implementation in bitcoinj-cash is outdated, I dont recommend using it.
I'm willing to update it, but its not a high priority at the moment. If you actually want to use it, let me know here.
Currently on the bitcoin cash network, 1 sat/byte fees are going through no problem. Transactions in bitcoinj, however, have an "ensuredMinRequiredFee" option that makes the minimum TOTAL fee be 1000 satoshis, which is usually about 4-5 satoshis per byte (outrageous!) So it needs to be default for the min fee to be much lower, perhaps even 0, as we move towards reinstating zero fee transactions in the future.
This is the code that I made. Is there anything to correct?
public void send(String toAddress , String amount)
{
try {
SendRequest request = SendRequest.to(Address.fromBase58(getMainNetNetwork(), toAddress), Coin.parseCoin(amount));
kit.wallet().completeTx(request);
kit.wallet().commitTx(request.tx);
kit.peerGroup().broadcastTransaction(request.tx).broadcast();
} catch (InsufficientMoneyException e) {
e.printStackTrace();
}
}
hi:
how can i use this library in android studio?
thank you very much
When wallet_tool syncs the blockchain from scratch, it automatically uses checkpoints to skip ahead in the chain and sync faster.
However, for testing purposes, it would be nice to be able to skip this feature and sync from the beginning of the chain.
I have noticed you can't use multiple outputs in a SendRequest using the emptyWallet option. I understand this makes sense when this outputs have a value but, what happens if the output is an OP_RETURN? Why should't be correct create an emptyWallet request including an OP_RETURN?
This is line I'm referring to: https://github.com/bitcoinj-cash/bitcoinj/blob/cash-0.14/core/src/main/java/org/bitcoinj/wallet/Wallet.java#L3986
Not sure if this is a bug or I'm missing any consideration.

The above is my code, I use TestNet to transfer to my wallet address mhCHrjrvtjnv1of8EN6ffGUe1iazeQUc7i, and then when the code is executed again, the balance of the wallet is rich, but when I turn out, the account balance is insufficient and the wallet information has several addresses. How should I make it correct Transfer your wallet with your wallet? Is there any problem with my code? Thank you very much. The following is the log:

but I broadcast get errors
https://test-bch-insight.bitpay.com/
An error occurred: 16: mandatory-script-verify-flag-failed (Signature must be zero for failed CHECK(MULTI)SIG operation). Code:-26
Please help me. I've wasted three days on this problem.
It was pointed out to me that my Bitcoin Cash Wallet app (for testnet) gets stuck at the November 13 hard fork.
In my bitcoincashj library, the difficulty adjustment algorithm for testnet does not work correctly. Since this library is based my library, then bitcoinj-cash probably has the same problem. I will work on a solution and submit it in the next week or so.
I don't see a way to make an Address object from a bech32 address.
Ideally there would also be a method to get an address without caring which format it is in.
And a way to convert an address into a bech32 string.
I can add this but probably won't get to it for a while.

Sometimes I cannot broadcast pending transactions because active peers size won't be larger than the value returned by PeerGroup#getMinBroadcastTransacions.
So, I want to call PeerGroup#setMinBroadcastTransactions before broadcasting pending transactions on startup...
I've been working on a small project with bitcoinj cash (great work by the way). Recently I tried to build it and got this error:
INSTALL_FAILED_NO_MATCHING_ABIS: Failed to extract native libraries, res=-113
I found this post on stackoverflow dealing with a previous version of bitcoinj:
In this issue, excluding the 'scrypt' module from bitcoinj got rid of this error, and it also worked for me. I'm interested if anyone else has this issue building for Android, and how they fixed it. In the post, they recommend switching to org.spongycastle.crypto.generators.SCrypt. If there's an easier way to fix this, that's great, but it might be worth looking into migrating to spongycastle's implementation.
While loading blk files before 2017.8.1, org.bitcoinj.utils.BlockFileLoader#loadNextBlock does not work well.
It looks like that the magic number for block before 2017.8.1 is 0xf9beb4d9L, instead of 0xe3e1f3e8L.
Extracts the checkpoint file.
There is no response even if I wait.

I'm trying to send a test transaction using Android / Kotlin, and encountered the SIGHASH_FORKID error, but even after using request.setForkId(True) it still doesn't work? Not sure whats going on?
Everything I find out there just says set the flag?
Received Reject: tx for reason 'mandatory-script-verify-flag-failed (Signature must use SIGHASH_FORKID)' (16)

SendRequest.to(Address.fromBase58(MainNetParams.get(), recipientAddress), Coin.parseCoin(amount))
request.setUseForkId(true)

kit.wallet().sendCoins(request)
