Hi

In june 2009 i was trying to mine bitcoin using commands, but i newer find or get any of this coins! The walue was to so smal at that time, so i didnt bother or work to hard to find them! I have been thinking about this for many years and i was thinking my computer was recykled years ago! But i find it and its up and runing! (Not online and stored safely now) It seems line the computer have «automined» every time it was online!
And dont ask me for any codes or numbers, im not stupid even of my bad english! 😂 And yes i know electrum did not exsist in 2009! I was using xml,json,sql…..

Does anyone know about this?: I have a «electrumkeyid», but i dont know what it is, or how to use it!

Here is how to sign a transaction with an offline Electrum wallet.

1. With your online (seedless) wallet, create the transaction using mktx:

./electrum mktx


XxxxxxAlot off numbers…. Xxxx

Note that returned json contains the unsigned tx in "hex". The field "complete" is false because the transaction is not signed, and "input_info" contains parameters that need to be passed to the offline wallet so that it knows which private keys to generate.

2. Sign the transaction with your offline wallet: pass "hex" and "input_info" to "signrawtransaction':

./electrum signrawtransaction

The command returns a fully signed transaction, as indicated by the "complete" field.

This transaction can be sent to the network with 'sendrawtransaction
