Re: seed that is NOT BIP39 will not be imported

Hi.

I used BitcoinJ as a base for my wallet, and have a 12-word seed. I have used the wallet a couple of years, and it still works for BTC.
If I manually direkt the client to a Cash-node, I also can see my BCH balance in that wallet, but it has no support for the changed difficulty-regime in Cash-chain, and I cannot sign transaction in Cash-chain.

Therefore I wantet to try Electrum Cash as a wallet for accessing my Cash...
When I start up, and tries to import my seed, it does not seem to recognise my 12 words unless I check for BIP39. But ofc, when recovering witn BIP39 my balance does not show up, since the keys in BitcoinJ is not BIP39.
Did you just use your own made up 12 word seed? Or did you generate one? I'm pretty sure that Bitcoinj is actually BIP39 compliant, as MultiBitHD was using BitcoinJ as it's base... and MultiBitHD was generating BIP39 seeds...

I suspect maybe your Derivation Path is wrong? Do you know what the derivation path of your BitcoinJ wallet is? I can't seem to find any documentation on it.

Why is the button to continue disabled when I don't check BIP39 ?  And how should I import my old wallet from BitcoinJ ?

Note - when using BitcoinJ, I can use any 12 words I want as seed, and it creates a wallet that is useable...  So why can I not just enter an 12 words and import as non-BIP39-seed using Electrum Cash ?
Because Electrum (and therefore ElectronCash, as it is a fork of Electrum) has it's own proprietary seed format that is not BIP39 compatible (the checksum calculations use different methods). This is why the "BIP39 seed" option exists. So, you can either restore from an Electrum seed or a BIP39 seed... but a made up random collection of words won't work.

Well... I have several seeds, and the one I had BTC in during fork was automatically generated for me by BitcoinJ.
I tested a recovery with this seed in MultiBitHD-wallet, and did not get the same addresses.
I also tested a seed from MultiBitHD with balance as a recovery with BitcoinJ, and the balance did not show up.

That's why I suspected that BitcoinJ-seeds are not BIP39.

I do not know what derivation-path is for my BitcoinJ-seed...
only used this method :
     DeterministicSeed seed = kit.wallet().getKeyChainSeed();
     System.out.println("Seed words are: " + Joiner.on(" ").join(seed.getMnemonicCode()));

and with those 12 words I can do :
      String seedCode = "xxx xxx xxx ...";
      long creationtime = System.currentTimeMillis()/1000l-60*60*24*30;
      DeterministicSeed seed = new DeterministicSeed(seedCode, null, "", creationtime);
      Wallet restoredWallet = Wallet.fromSeed(params, seed);

And start the wallet-kit in normal way, and it finds all transactions to my own wallet the last 30 days.

But the same 12 words is evaluated as BIP39 by the EElectrum/Electron-wallets, but then again - I don'w know the Detivation-path, so I let it be unchanged... So maybe that's what's worng...

You should re-post to the Electron-cash subforum...

Not quite sure how to find that...  I have looked a bit around here..  Could you provide me with a link ?

Why is blocks not 'filled up'?

⭐ Merited by ETFbitcoin (1)
I notice that every once in a while, there comes along blocks with lots of space left over even when there are loads of unconfirmed transactions.
Like this one : https://blockchain.info/block/000000000000000004ae1a3b7ac7c7422a779e4ea9eb8e3c14935a80ca51dc17
This block was mined when there was over 6000 unconfirmed transactions.
What's the logic behind not filling up the block? Don't this just delay the whole network and give less transaction-fees to the miner ?

Looked pretty 'nice' in this list : https://en.bitcoin.it/wiki/How_To_Buy_Bitcoins_With_Your_Credit_Card
But when they after one week hasn't replied to any mail or any feedback on their site, I cannot think that this is nothing but a scam.
Of course the payment-link on the order leads to PayPal-payment as 'friend' and there is no option to dispute it via PayPal.

I expereince the same with Bitxim. Their payment-option was paypal-friend, and they don't answer on any mail-address or 'servicerequest' on their 24/7 service...

I dont have editor-privs og the list, så if anyone could put them up as scammers - feel free Smiley

needs editor- or someone to flag BitXIM as 'scammer's.  My experience is that for one week they have not responded to emails on any account, and I have not recieved bitcoins from them.  They were listed as "Bitxim is a professional, reliable and accessible German bitcoin exchange."
but this cannot be true...
