H I believe I ran into similar issues a while back - have you tried
whitelisting the IP of your bitcoinj client in the Bitcoin Core conf?
I also vaguely recall getting stalled connections from time to time and
adding logic in my app to hack around it by disconnecting and reconnecting.

This is normal due to how UTXO-based cryptocurrencies operate. The
remaining value from the spent UTXOs is "sent back to yourself" via a

Dust threshold is slightly more complicated now due to transition from

20 millibits says that the block parser is choking on a transaction that
spends a SegWit UTXO.

It looks like the bitcoinj documentation site is open source and located
here: https://github.com/bitcoinj/bitcoinj.github.io
So if you have updated examples, you should be able to create a pull
request to fix them in that repository. Thanks!

When you generate a private key it's up to you to keep track of it,
preferably without telling it to anyone else.
The key space for bitcoin is huge; the chance of a collision with someone
else's key is essentially zero.

Bitcoin block space is in high demand these days; if you're trying to send
amounts less than 0.005 BTC (assuming only 1 input) then it probably won't
make economic sense to do so.

Hm, "priority" is an outdated concept in Bitcoin since the emergence of the
fee market. I suspect that this older 0.12.1 node tried to use the priority
rules to decide whether or not to accept the transaction because you did
not pay a sufficient fee. I see in your debug output you paid 0 fee: fee
ity of your new protocol. Tread carefully...

BitcoinJ isn't compatible with any of the Hyperledger projects to my
knowledge. Fabric and Sawtooth Lake, for example, are not Bitcoin-style
blockchains - they are new types of distributed ledgers that don't share
much in common with Bitcoin and thus BitcoinJ can't interact with them.

I don't think replay protection can be added at the network level. Peers
could lie about their software version and/or switch it, plus it's highly
likely that a chain split won't result in a clean network partition.
Transactions will get relayed around the network comprised of nodes on both
chains
I'd recommend reading the wallet documentation here:
https://bitcoinj.github.io/working-with-the-wallet
If you want to specify which nodes you push the transactions to, you can
create a PeerGroup that you only add Peers to which you want to push the
transactions. Then to push the transactions, cal
Can you be more specific?
Do you mean that you already have a signed, valid transaction hex and want
to broadcast it to the network?
Or are you asking for how to build and sign a transaction using a BitcoinJ
wallet?

I suppose that's their fancy way of saying that your node no longer follows
the same rules of newer nodes that don't accept alert messages.

Are you saying that this is breaking your application? This looks like
normal behavior to me - it just means that you received an orphan block /
out of order block and bitcoinj ignored it. In most cases, bitcoinj should
end up receiving more blocks that eventually connect them together. I have
