I’m taking part in round with bitoinj and I can not seem to even get essentially the most primary performance working.
What I wish to do: I’ve one pockets with one deal with. I wish to dowload blockchain and from that, get the pockets steadiness.
What I did is following code (in scala, nevertheless it is kind of the identical factor as Java), the pockets is in deal with.walet, I would like the blockain to be saved at saved.blockchain:
val params = NetworkParameters.prodNet
val walletFile = new java.io.File("deal with.pockets");
val pockets = Pockets.loadFromFile(walletFile)
val key = pockets.keychain.get(0)
val deal with:String = key.toAddress(params).toString
println("ADDRESS IS : "+deal with)
val blockStore = new BoundedOverheadBlockStore(params, new java.io.File("saved.blockchain"))
val chain = new BlockChain(params, pockets, blockStore)
val peerGroup = new PeerGroup(params, chain)
peerGroup.setUserAgent("BitToy", "0.1")
peerGroup.addPeerDiscovery(new DnsDiscovery(params))
peerGroup.addWallet(pockets)
println("START DOWNLOADING BLOCKCHAIN")
peerGroup.begin()
peerGroup.downloadBlockChain()
peerGroup.cease()
println("DONE; BALANCE IS :")
println(pockets.getBalance)
I do have steadiness on the deal with within the pockets.
Now, after I run it for the primary time, the blockchain (or, reasonably, the headers) will get downloaded and I see the proper steadiness. Nevertheless, after I run it for second time, I simply see:
ADDRESS IS : [correct address here]

and the steadiness is zero. If I delete the saved blockchain and let it re-download once more, it really works once more, however just for one time.
What am I doing improper?
