I am trying to redeem a multisig transaction using the bitcore.io library (signing client side in the browser). I need the unspent outputs to to do so. Both Blockchain.info and Biteasy.com have an unspent outputs endpoint:

BLOCKCHAIN.INFO: https://blockchain.info/unspent?active=3CmmhMciChAx4FtGxHtYppoPBLpRLcBy1H

BITEASY: https://api.biteasy.com/blockchain/v1/addresses/3CmmhMciChAx4FtGxHtYppoPBLpRLcBy1H/unspent-outputs

I understand there are small differences between the 2 APIs but... they seem to differ heavily.

• The tx_hash (db29...) and transaction_hash (9e07...) are not the same?!
• The tx_index (5480...) and transaction_index (0) are not even close (guess the transaction_index from Biteasy matches with the tx_output_n (0) from Blockchain but if so, what is the tx_index (0))?
• The script (a914...) and script_pub_key (HASH...)  are in a different format (guess you can encode one in the other)?

Do they simply use different ways to present the same data or is the data different between the two?

Trying to understand the following:

I signed a 2-3 multisig raw transaction and sent the signed hash to the counter-party. The counter-party will sign with their private key and send the transaction to the network.

As far as I understand it the counter-party will need to include the unspent outputs to the signrawtransaction RPC command like I had to do the first time (the hash I signed is not enough, is it?). Now, how does the counter-party know which unspent outputs to include? I suppose the counter-party needs the same outputs as me and he might pick different ones or pick a different fee. Am I supposed to send him the signed hash and the transaction array I used to sign it the first time (including the redeemScript)?

Thanks!

Hey Bitcoin Gentenaars,

Ik ben bezig een overzicht te maken van alle Bitcoin meetups in België. Zie: http://meetups.bitcoinassociation.be/

Heb net de Bitcoin Meet Gent toegevoegd. Laat me zeker iets weten als jullie weet hebben van andere Bitcoin meetups!

Bedankt.

It seems we have 2 Bitcoin meetups in Antwerp. There is the one announced in this thread and another one at http://www.meetup.com/Bitcamp/. Maybe we can merge the 2 meetups in one? I am collecting all the Belgian meetups at http://meetups.bitcoinassociation.be/ to make it easier for people to find one nearby.

www.cryptocoincharts.info has some, not all, altcoins but it's nice to see their relative values.
