How to create a P2SH address which will be the hash of a redeemScript

How to create a P2SH address which will be the hash of a redeemScript

Suppose I have a redeemScript and I want to create a P2SH address corresponding to the hash of that redeemScript. How do I do it?

I was thinking of bitcore-lib but I'm not sure I am going in the right direction. Below is my staring point and I am not sure what to do next.

Also the scriptPubKey appears to be 0x04 and it has to be 0x05.

And how do I further generate my keys for this new address?

> var bitcore = require('bitcore-lib');
    undefined
    > var redeemScript = bitcore.Script.fromASM('OP_SHA256 001xxxxxxxxxxxxxxxxxxxx6 OP_EQUAL');
    undefined
    > var scriptPubKey = redeemScript.toScriptHashOut();
    undefined
    > scriptPubKey
    <Script: OP_HASH160 20 0x04xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx6 OP_EQUAL>
    > scriptPubKey.toAddress()
    3xxxxxxxxxxxx
    > scriptPubKey.toHex()
    a914xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx287

Another option will be to use this:

bitcoin node: what is the difference between simnet and regtest?

bitcoin node: what is the difference between simnet and regtest? btcd, and presumably other bitcoin node implementations, seem to have 4 network options: mainnet testnet regtest simnet. I get that mainnet and testnet both are "public" in that your node will communicate with other nodes and that both have an existing blockchain and genesis block. However, from what I can tell, both simenet and regtest both create a local only blockchain, and both will create a new genesis block. I this case, what is the difference, and which is better (easier) for developing bitcoin applications? This is what the documentation has to say: --regtest Use the regression test network --simnet Use the simulation test network https://ift.tt/2TAMkwe

How to check if Electrum is masking my IP with the Tor proxy?

How to check if Electrum is masking my IP with the Tor proxy? When i start Electrum from the command line i see this mensage: (python3:7069): dbind-WARNING **: 14:09:58.452: Couldn't register with accessibility bus: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken What does it mean? I just installed Electrum following this tutorial: http://docs.electrum.org/en/latest/tor.html I followed the instructions from this topic " Option 2: Multiple servers but Tor Main ". I installed Electrum using the command line on Ubuntu, check the " Installation from Python sources " on this link https://electrum.org/#download if you want to see the codes. And i used this code bellow to download the Signatue keys: $ gpg --keyserver pool.sks-keyservers.net --recv-keys 2BD5824B7F9470E6 I checked the both checkbox: 1)...

Tor proxy on Electrum, what does Port: 9150 and 9050 mean?

Tor proxy on Electrum, what does Port: 9150 and 9050 mean? The first time that i installed Electrum i navigated to Tools->Network->Proxy i saw there a checkbox "Use Tor proxy on port 9050", i had a problem with my OS so i had to reinstall my OS, Electrum and Tor, and now instead of "port 9050" it's "port 9150". I think that it's because i'm using the Tor Bundle, as said on this electrum docs , downloaded from here: https://www.torproject.org/projects/torbrowser.html.en#linux i want to know what is the difference between the port "9050" and "9150". And if i'm fine using the "9150". https://ift.tt/2T0EvmY
