Thanks, i'll ask him what are his fees.

No, I tried to register a long time ago, but couldn't since at the moment they didn't allow users from Spain, so I forgot all about them. Just Googled them to read some opinions.

Made some research on Coinbase, this doesn't look good: https://www.reddit.com/r/Bitcoin/comments/419gtr/coinbase_has_closed_my_account_without_allowing/

Thanks for the info, I'll check it out.
For now I'll use multisigna or localbitcoins.

Does it require KYC, etc? SEPA transfers are done between users or to a Coinbase account?

Thanks!

Hi,

I'm buying 0.5 BTC with SEPA at www.multisigna.com (username netsuke) at market price.

Regards

Ok, thanks.

Lock the the payment to a set of addresses. For example address 3jhGu... Can only spend its bitcoins to pay addresses 1huyt... & 1PLo2...

Hello,

Is it possible to lock the output addresses of a Multisig address?

Thanks

Ok, thanks I'll try to write a tutorial with the information given here.

Yes, but to build the header I need to know the nBits and I don't know where to find that value.

Thanks for the reply.
There is one piece of information from the block header I don't know where to get it from. It says the target threshold is needed, but does not say what it is. Is it the current difficulty?

Hello,

I'm having a hard time trying to find what is exactly being hashed ( plus the nonce ) to find the string with enough 0's.
I've tried the previous tx hash, the current and previous Merkle root, but no luck.

Does anyone know?

Thanks

It's easier to use electrum client to send raw transactions.

Thanks

I found out the blockchain hasn't been completely downloaded. Maybe this is the issue?

That transaction is already signed by 2 of the 3 private keys. It is a valid transaction waiting to be sent to the network.

Hello,

I'm trying to send a raw Multisig transaction but getting error -25. The transaction is correct since sending it through Blockchain works.

Any ideas?

Thanks!
