I am using this bitcore npm package. https://bitcore.io/api/lib
And i want to monitor all the transactions over the blockchain, and read the input address, output address and amount associated with that transaction.
But i am unable to find the javascript method to invoke to accomplish this. Even i am not able to find a example for this.
I am looking for as short as something like

QUESTION
I am developing a wallet for HappyCoin which is similar but different fork of Bitcoin.
Since this coin doesn't have addressindex rpc methods(getaddressbalance, getaddressdeltas, getaddressmempool, getaddresstxids, getaddressutxos), I can't get utxos and transactions for a specific address.
Since it is quite different from Bitcoin I can't use bitcore-lib or bitcore-node.
How can I get utxos and transactions related to a specific address using legacy rpc methods?
Here are the rpc methods this coin supports.
I've tried with listunspent and listtransactions but these only work with local wallet address not other addresses.
...ANSWER
Answered 2019-Sep-05 at 03:39You could try first importing the address as a watch-only address into your wallet using:
importaddress
[label]
Once the rescan is complete (it has to scan the entire blockchain for all transactions related to this address), which can take over an hour.
You should then be able to use the wallet commands to list unspent and tx'es.
QUESTION
I have a derivation scheme starting with tpub... for testnet and I want to be able to generate bitcoin addresses from derivation scheme. Also I want a method be applicable to mainnet, is any library available that could help me in this task. And code example how to do it what be great. I was thinking bitcore-lib would help, but didn't found anything useful for my task. But any solution would be fine. All useful information I found was a bunch of bips, but I doubt that I need to do that from scratch, and want to avoid it.

QUESTION
I am using bitcore-lib to decode transactions encoded in hexadecimal, but I'm getting a weird result. For comparison, I've used bitcoinjs-lib and it seems to be working just fine.
Network: bitcoin testnet

...ANSWER
Answered 2018-Sep-19 at 08:34Your transaction is a segwit* transaction and bitcorejs does not support it.
From reddit:
SegWit input scriptSigs will have one of these patterns:
- 0x160014<20 bytes> (P2WPKH)
- 0x220020<32 bytes> (P2WSH)
A great alternative to bitcorejs in my opinion is bcoin: it have the same capabilities (running a full node) plus segwit support and it has a similar architecture so it's easy to migrate to it from bitcore.
QUESTION
I want to run full node on my box, and write a program using bitcore-lib using which I can get balance from a given address and also transfer money, using the running full node on my box. I would really appreciate any pointers to achieve it.
...ANSWER
Answered 2018-Sep-13 at 16:22How to connect bitcore-lib to a running full node-bitcoin
Use npm to install bitcore-lib. It should also come with it's own version of bitcoind (unsure if they've switched over to bcoin). If not/you're unsure, you can download and set up your own bitcoind node by cloning the bitcoin repository and follow the docs on setting it up on your machine (OSX, Linux, Windows, etc)
Then, to configure bitcore-lib to connect to your node, you can configure your bitcore-node.json file to look something like this.
QUESTION
I've installed bitcore (https://github.com/bitpay/bitcore) using "npm install -g bitcore" with NVM running node v4.8.2, confirmed with "node -v" and "which node".
The CLI works, and I am able to run my full node as a service (using pm2).
However, I want to use bitcore-lib in my app, which I have added to my dependencies. In my code I have a little test to make sure I have my modules working, which looks like this:
...ANSWER
Answered 2018-Apr-26 at 21:52Global modules are not requireable - global installs are only for command line tools.
If you require it, it's a dependency - so it needs to be locally installed and in your app's package.json.
QUESTION
I'm importing bitcore-mnemonic in my React project with this conditions:
- I'm importing it just once and in one file.
- The component utilising it is imported just once and is called by
react-router. - No other library is using
bitcore-lib. How did I find? searchednode_modules. - I'm importing as
import mnemonic from 'bitcore-mnemonic';.
And I'm getting this error while running unit tests:
Uncaught Error: More than one instance of bitcore-lib found. Please make sure to require bitcore-lib and check that submodules do not also include their own bitcore-lib dependency.
Please help me know what I'm doing wrong.
...ANSWER
Answered 2017-Sep-30 at 17:37bitcore-lib creates a global object named _bitcore, and every time you want to create an instance it checks to make sure that object is not available.
To solve this, I simply delete this variable before requiring:
