Until earlier this month, bitcoin and Bitcoin Metselspecie addresses used the same format, making it difficult to ensure you were transacting using the keurig currency’s address. Te order to simplify the process for transacting with both bitcoin and Bitcoin Specie for our users, Blockchain wallets are now using an a fresh format (CashAddr) for Bitcoin Specie addresses.

Q: Why do my Bitcoin Metselspecie addresses look different?

A: Bitcoin Metselspecie developers have proposed a fresh format for addresses to help differentiate inbetween bitcoin and Bitcoin Contant addresses, called CashAddr . This updated format only switches how your Bitcoin Metselspecie addresses are displayed, not the underlying private and public keys.

Q: Why has Blockchain implemented this switch for users’ wallets?

A: Wij want to proceed improving the user practice for both bitcoin and Bitcoin Contant within users’ wallets. Ultimately, having a different address format for each will help you distinguish which currency you’re transacting with, permitting you to use BTC and BCH more lightly.

Q: What is the difference inbetween the address formats?

A: Bitcoin Metselspecie addresses now look like this: qp3wjpa3tjlj042z2wv7hahsldgwhwy0rq9sywjpyy. They can also have a prefix (bitcoincash:qp3wjpa3tjlj042z2wv7hahsldgwhwy0rq9sywjpyy). Each Bitcoin Specie address also has a “legacy address”, which is it’s corresponding bitcoin address. You can find the legacy address for each BCH address on Blockchair . Take a look here to see an example of the difference inbetween legacy and CashAddr addresses.

Q: What do I need to do?

A: Nothing, we’re taking care of it for you! Your wallet will now only demonstrate Bitcoin Metselspecie addresses te this fresh format. The only thing wij encourage you to do is to commence sending and receiving using the updated address type.

Q: Can I still send to the original ‘legacy’ address?

A: Technically yes, but it would benefit both you and the community to start using the fresh version. Don’t worry, if you have a legacy address that is presently being used, it will proceed to work. If you proceed transacting with your legacy addresses, they will be displayed ter your transaction feed spil the BCH CashAddr address omschrijving.

Q: Is this a protocol switch, soft-fork, or hard-fork?

Q: Where can I dive into more technical details?

A: You can find more details on this update here .

Earlier today, wij announced a partnership with SFOX that lays the groundwork for our users ter the US to seamlessly buy and sell digital assets with greater reliability and without compromising user security or control.

At Blockchain, wij’re striving to write reusable, extendable, and pliable code. This practice has become even more significant with the latest addition of Bitcoin Specie and ether to our wallet application. For our users, adhering to writing agnostic components makes project delivery speeds swifter and more consistent. For our developers, it makes the code joy to work with and less buggy.

A few months ago, wij added ether to the Blockchain wallet along with a crypto-to-crypto exchange integration. This feature wasgoed the very first we’ve built that supports numerous cryptocurrencies (instead of just bitcoin to fiat or vice versa). Ter our efforts to build reusable, extendable, and supple code wij built it to support any digital currency our wallet presently offers or will suggest te the future.

The components that make up our exchange integration are totally agnostic to the currencies the user wishes to shift. Any digital currency can be plugged into the integration spil long spil it’s “API” ter the My-Wallet-V3 core supports a few basic functions. Let’s walk through how this works a little bit.

When the wallet initializes the exchange checkout process it passes the destination and origin wallets to the shift-create component from the shapeShiftCheckout controller:

And ter My-Wallet-V3-Frontend/app/partials/shapeshift/checkout.pug

Note: There are more attributes passed to the shift-create component, but for plainness I’ve liquidated them.

The line ter shapeShiftCheckout.controller.js (`this.wallets = Wallet.accounts().concat(Ethereum.defaultAccount),`) wasgoed for shifting inbetween bitcoin and ether when wij originally launched the ether integration. What it does is concatenate all the bitcoin wallets te your Blockchain wallet with the ether default wallet. Ter checkout.pug, wij tell shift-create to flow thesis wallets spil possible origins and destinations te an exchange.

A few months zometeen, wij added total support of Bitcoin Metselspecie to our wallet. Wij desired to give users the capability to exchange their Bitcoin Contant to and from bitcoin and ether. Here is the commit that added Bitcoin Specie to our exchange integration: https://github.com/blockchain/My-Wallet-V3-Frontend/commit/0c44b5bca7951a9a298d5599d5fd872b0eff5de5 .

Adding Bitcoin Metselspecie wasgoed spil effortless spil switching one line of code because wij built cryptocurrency agnostic components for exchanging bitcoin <,->, ether from the beginning.

If you check the shift-create component where the wallets are passed, you won’t find any reference towards a specific cryptocurrency itself: ( https://github.com/blockchain/My-Wallet-V3-Frontend/blob/master/assets/js/components/shapeshift/shift-create.component.js ). You’ll only see functions called on the wallets that the API te My-Wallet-V3 core requires them to have.

  1. `getAvailableBalance` ->, How the component calculates the total amount the outgoing wallet has available to send/exchange. Below are the functions for each cryptocurrency:
  1. bitcoin: https://github.com/blockchain/My-Wallet-V3/blob/master/src/hd-account.js#L311
  2. ether: https://github.com/blockchain/My-Wallet-V3/blob/master/src/eth/eth-account.js#L138
  3. Bitcoin Specie: https://github.com/blockchain/My-Wallet-V3/blob/master/src/bch/bch-account.js#L68
  • coinCode ->, The wallet’s coinCode to be used straks ter the cryptoCurrencyMap.
    1. bitcoin: ‘btc’
    2. ether: ‘eth’
    3. Bitcoin Contant: ‘bch’
    4. Balance ->, Used to check for balance updates ter the wallet. If a user’s balance switches, the component calls getAvailableBalance.
    5. cryptoCurrencyMap ->, Used to calculate conversions inbetween each digital currency and their fiat values.
    6. When everything comes together, the final result looks like this:

      Despite the ease of adding fresh currencies, wij desired to proceed improving the exchange practice for our users.

      Te version 1 of our exchange integration, there wasgoed no loading state to tell users that the component wasgoed working on getting a quote. Under good network conditions requests like thesis can seem instantaneous and a loading state might even seem a little jarring. However, because of the high traffic on digital currency networks, requests can take up to Five seconds to resolve. Bitcoin, ether, Bitcoin Contant, and other digital currencies are treating more transactions than they everzwijn have before. Record high transaction volumes are leading to network congestion, te turn leading to slow loading times from services like ShapeShift.

      Depending on how long a request took to make, it could look like the component wasgoed frozen or that something broke and no error wasgoed returned. Te reality, a request wasgoed being made and wij weren’t correctly indicating that to the user. Wij determined to add a loading state to the component spil you can see ter version 1 vs version Two below.

      Version Two Version 1

      Users were loosened to see an indication of the app working to get a quote after the launch of version Two. Our transaction volume enlargened by 10% the week after wij flipped out thesis switches,

      30% overheen the Two weeks after, and 75% overheen the following month. Seemingly petite improvements like this make a big difference to users.

      Building components that are resilient to cryptocurrency’s rapid growth and onveranderlijk switch is just one of the many ways wij ensure our users are getting a best-in-class practice on our verhoging. Wij hope you’ve loved learning a little more about our process and look forward to continuing to supply fresh and innovative solutions te our effort to create an open, fair, and accessible financial future.
