Unable to get balance with bitcore lib

Unable to get balance with bitcore lib

Using latest version of bitcore lib , want to check balance for making tx but once I include

var explorers =require('bitcore-explorers');

after

var bitcore =require('bitcore-lib');

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.

I had a look at this thread

Bitcore = "Error: More than one instance of bitcore-lib found"

but it does not help . When I comment out this part

var bitcore =require('bitcore-lib');

explorer seem to be running but the problem is it always returns 0 for all the wallets . For instance this wallet has fonds wallet testnet fonds

here is the code

const insight = new explorers.Insight();
insight.getUnspentUtxos('mkFPBvd3jbPYn4223SNTneBWHodziU287G', function(err, utxos) {
    console.log(utxos);
    let balance = 0;
    for (var i = 0; i < utxos.length; i++) {
        balance +=utxos[i]['satoshis'];
    }
    console.log('balance:'+ balance);
});

and response is always [] , 0

1) How to check balance using bitcore without conflict with bitcore-lib ?

2) Which is the "web3" (most commonly used for ethereum) node js library for bitcoin ?

Thanks a lot !

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?

Need help to recover blpckchain.info wallet, my wife forgot her password and the brute force with btcrecover is not catching the password

Need help to recover blpckchain.info wallet, my wife forgot her password and the brute force with btcrecover is not catching the password I used btcrecover to extract the wallet file (wallet.aes.json) from a blockchain account and I have been running btcrecover with dictionaries of my making but it has been going on for weeks and I am running out of ideas on how to permutate what my wife and I think the password could have been. Is there a way to just manually transfer the btc from the old wallet into a new wallet we do have access to or is there any way to extract the password or private keys directly from the wallet file? We have: the phone with the original wallet app installed, the wallet file pulled using btcrecover, access to the email to allow authorization to access, the wallet identifier that was sent to her email when she first signed up, the phone which has the wallet, the pin that was used for the wallet, and we know how much btc is in the account. We do not have: The pri...
