    Suspicious automatic download opens ripple wallet.... techy help

    Posted: 06 Sep 2019 06:20 PM PDT

    Hi guys. I'm not as techy as some of you. I was just browsing normal sites and out of nowhere safari downloaded two files. I will post the details of the files below. When I open the files it automatically opens my ripple ledger wallet. What appears the same app I use when plugging in my ledger. I have not plugged it in. This file comes from adware?

    from ad.doubleclick.net then has a huge address.

    ​

    Could this be trying to steal my ledger when plugged in? when opened, it opens what appears to be the ripple ledger wallet asking to plug in

    Public websockets to access live trade and order book data from Binance, Bittrex, KuCoin, Kraken, and more.

    Posted: 06 Sep 2019 03:43 PM PDT

    Hi Everyone,

    We've seen a lot of interest from people in this group to access live websockets for trade and order book data. To help everyone out, we've made our websockets open to the public. That means you can access websockets to all 16 exchanges we support here:

    https://developers.shrimpy.io/docs/#websocket

    You don't need to sign up for an account or anything. The data is completely public for use. Just install the python or node libraries to get quick access to the data here:

    https://github.com/shrimpy-dev

    Try a few different pairs and exchanges - I think you will find it pretty exciting!

    I'm happy to answer any questions if you have some. Looking forward to hearing your feedback!

    Soon we will be releasing historical order book snapshots and trade data as well for the 16 exchanges we support. Check back next week and it might be ready!

    Monero : Multisig support added to JavaScript RPC, Java RPC and JNI, and C++ libraries

    Posted: 06 Sep 2019 12:25 PM PDT

    https://np.reddit.com/r/Monero/comments/d0j6b7/multisig_support_added_to_javascript_rpc_java_rpc/

    Here's a demonstration of creating N/N, (N-1)/N, and M/N multisig wallets in Java using native bindings to Monero Core.

    public static void main(String[] args) { createMultisigParticipants(2, 2); createMultisigParticipants(2, 3); createMultisigParticipants(2, 4); }

    private static List<MoneroWallet> createMultisigParticipants(int M, int N) {

    // create participating wallets List<MoneroWallet> wallets = new ArrayList<MoneroWallet>(); for (int i = 0; i < N; i++) { wallets.add(MoneroWalletJni.createWalletRandom("testwallet" + (i + 1), "supersecretpassword123", MoneroNetworkType.STAGENET, new MoneroRpcConnection("http://localhost:38081"))); }

    // prepare and collect multisig hex from each participant List<String> preparedMultisigHexes = new ArrayList<String>(); for (MoneroWallet wallet : wallets) preparedMultisigHexes.add(wallet.prepareMultisig());

    // make each wallet multsig and collect results List<String> madeMultisigHexes = new ArrayList<String>(); for (int i = 0; i < wallets.size(); i++) {

    // collect prepared multisig hexes from wallet's peers List<String> peerMultisigHexes = new ArrayList<String>(); for (int j = 0; j < wallets.size(); j++) if (j != i) peerMultisigHexes.add(preparedMultisigHexes.get(j)); // make wallet multisig and collect result hex MoneroMultisigInitResult result = wallets.get(i).makeMultisig(peerMultisigHexes, M, "supersecretpassword123"); madeMultisigHexes.add(result.getMultisigHex());

    }

    // if wallet is not N/N, exchange multisig keys N-M times if (M != N) { List<String> multisigHexes = madeMultisigHexes; for (int i = 0; i < N - M; i++) {

     // exchange multisig keys among participants and collect results for next round if applicable List<String> resultMultisigHexes = new ArrayList<String>(); for (MoneroWallet wallet : wallets) { // import the multisig hex of other participants and collect results MoneroMultisigInitResult result = wallet.exchangeMultisigKeys(multisigHexes, "supersecretpassword123"); resultMultisigHexes.add(result.getMultisigHex()); } // use resulting multisig hex for next round of exchange if applicable multisigHexes = resultMultisigHexes; }

    }

    // wallets are now multisig participants return wallets; }

    This could be useful to integrate Monero wallets with multisig support on platforms like Bisq or Android. The messaging to exchange multisig information among participants is currently outside of the scope of these libraries, but rbrunner's mms could be useful for that.

    All libraries conform to the same interfaces outlined in this spec, which has been updated with multisig, method parameter types, and corrected ulongs vs uints per feedback.

    If anyone wants to help out, there are opportunities across all libraries, which are documented in their respective issues. Any help would be great.

    Java (JNI and RPC): https://github.com/monero-ecosystem/monero-java JavaScript (RPC only): https://github.com/monero-ecosystem/monero-javascript C++ (native binding to wallet2): https://github.com/woodser/monero-cpp-library API spec: http://moneroecosystem.org/monero-java/monero-spec.pdf

    Edit: I should add:

    The JavaScript library is released as a npm module. A simple web application is included in the JavaScript library to demonstrate creating a browser application. It currently depends on RPC endpoints, but it may be possible to be fully client-side in the future. I think it would be really cool if someone built a sample wallet UI or a stress testing tool in which funds are deposited and transactions are generated. The library tries to make it easy to build such applications. This release makes breaking changes to the wallet API. Specifically, in order to support multisig, the return type when sending transactions is now a MoneroTxSet which contains references to individual transactions, rather than returning the transactions directly.

    What is being decentralized with the blockchain?

    Posted: 06 Sep 2019 02:43 PM PDT

    We hear the word 'decentralization' and we immediately think about the blockchain, but what is being decentralized? Ledgers, authority?

    I am currently working on a presentation about the blockchain, but I can't seem to find the answer to the simplest question; what IS being decentralized with the blockchain? My thought went to authority or ledgers, but those two just don't sound right.

    Definitely a little clueless at the moment. Could anyone please help me?
