Forking, Cashing, and Witnessing

At Blockchain, our priority is always our users and the safety of their funds. We recently communicated that our service would be unavailable during the Segwit2x hard fork. While plans for the hard fork have been suspended, there may be some network instability at block height 494,784.

We’ll be monitoring the network closely. Should network instability threaten the safety of our users’ funds, we may briefly suspend outgoing bitcoin transactions but anticipate any suspension to last no more than 1 hour.

Moving forward, we are prioritizing two major initiatives to improve our users’ experiences in the digital currency ecosystem:

SegWit

Our block explorer, Blockchain.info, has supported SegWit from the day it activated. In 2018 we will be rolling out support for SegWit within our wallet products. This will be a major and complex update to some of the most sensitive parts of our codebase, across a wide variety of platforms and devices, affecting billions in user transactions with potentially significant privacy implications. We will do this cautiously but also with consideration for the rising miner’s fees within the bitcoin ecosystem. We are excited about the advances SegWit offers and we plan to begin making it available within our wallets in as soon as possible in 2018, with an eye towards rollout in Q1.

Bitcoin Cash

We launched partial Bitcoin Cash support on October 11th and said we would monitor market demand for fully featured support. Market demand for Bitcoin Cash has proven strong and, in our view, it’s likely here to stay.

We plan to offer full support for Bitcoin Cash before the end of year on web with support across all our platforms before end of the end of Q1 2018. Stay tuned for product launch announcements!

Meet our Team: November 2017

With less than two months left in 2017, we’re waiting (some more enthusiastically than others) for snow fort season to begin. In the meantime, we’ve kept a clear focus on enhancing our platform for our 18+ million users around the world. Here are some of the newer team members helping us do just that and then some.

Beyond Backups: How to Use Your 12-Word Recovery Phrase

Your 12-word recovery phrase is, without a doubt, one of the most important wallet tools at your disposal. Knowing that, it’s no surprise we strongly recommend users write it down and store it safely before adding any funds to a new wallet. If you’ve already completed these backup steps, it’s equally important to have a solid understanding of how to use your 12-word phrase if you ever need to. Here, we’ll explain exactly that!

SegWit2x Hard Fork: Frequently Asked Questions

When block 494,784 is mined (on or around November 16th), the second and final part of an important network upgrade to the Bitcoin protocol called “SegWit2x” will take place. Below is a quick breakdown of what to expect throughout the coming weeks.


Some background on SegWit2x
SegWit2x is essentially a software upgrade that will bring improved capacity to the Bitcoin protocol.  A majority of Bitcoin miners have signaled their intent to deploy Segwit2x, which increases the base size of bitcoin transaction “blocks” (groups of bitcoin transactions). The final part of this change is scheduled to occur when bitcoin block 494,784 is mined. Right now, this protocol change will likely activate on or about November 16th.

How does Blockchain plan to respond to SegWit2x?
During the upgrade, unanticipated changes to the Bitcoin network may occur. Our team is working around the clock to ensure our platform is prepared to incorporate these changes to the network as quickly as possible.  During the upgrade period, we will take steps to ensure users are protected and their funds are safe.

To keep your funds safe while the network is in transition, we will temporarily suspend bitcoin send, request, buy, sell, and exchange functionality roughly 24 hours before the time of the fork until the network stabilizes.

What happens if there is a network split?
There is a significant possibility that the planned hard fork will result in two bitcoin block chains. In this case, we will follow the chain with the most accumulated difficulty and refer to that chain as bitcoin. If the minority chain has significant value, we will make that value available for customers to hold or exchange for a period of time, as we have done with Bitcoin Cash. If the minority chain is the one with 1MB blocks, we plan to call it BT1. If the minority chain has 2MB blocks, we plan to call it BT2.

Is there any action I need to take in advance?
While no immediate action is required, we encourage you to write down your backup phrase if you haven’t already. Check out this blog for more info on that.

Will I be able to see my bitcoin in my Blockchain wallet?
Yes. We will temporarily be suspending transactions for bitcoin, but your funds will remain safe and you’ll be able to monitor them from within your Blockchain wallet. Please note, until the network stabilizes, your bitcoin’s fiat balance will be based on the value of bitcoin at the time of the hard fork.

Can I use ether during SegWit2x?
Yes, ether will be available during SegWit2x. If you have transactions you need to make during this time, we recommend using ether to send and request.  

When are you suspending buy and sell functionality for bitcoin?
We will be suspending all buy and sell functionality roughly 24 hours before the fork.

When will you bring back transactions? Will you be offering replay protection? 
We’ll bring back transactions when it’s safe either because there is one chain or funds are protected by our own replay protection.

Where can I find the latest updates?
We’ve created a status page at blockchain-status.com where we’ll be posting regular updates throughout. We will have updates featured on throughout the wallet as well.

Have additional questions? Our industry-leading support team is prepared, as always, to help answer your questions at support.blockchain.com.

Ether is Now Available on iOS & Android

A few months ago, we added ether to the Blockchain wallet. Today, we’re excited to announce that we’re extending that functionality to our mobile apps. As of today, users can seamlessly store, send, and receive ether on both iOS and Android.

As part of our mission to make digital assets increasingly user-friendly and accessible, we kept the mobile user experience for both currencies consistent and easy to navigate. With this update, users will notice the following two exciting changes:

  1. With a simple tap users can navigate between ether and bitcoin to monitor transactions, send funds, or request payment; and
  2. We’re rolling out a new dashboard that will allow users to monitor the market price for both currencies.

As always, users can find the latest mobile versions at our App Store and Google Play Store links.

Bitcoin Cash is now available in the Blockchain Wallet

Since the Bitcoin Cash (BCH) hard fork activated on August 1st, we’ve continued to monitor this emerging digital asset and confirmed in a brief update our decision to roll out limited support, in line with our users’ requests, within approximately 8 weeks.

We’re excited to share that, as of today, any user who had a Bitcoin balance in their Blockchain wallet when the fork activated, will be able to access the same amount in BCH.

Users can now store, exchange, and send Bitcoin Cash by clicking on General in the Settings menu of their web wallet. In the future, we may offer expanded support.

If you choose to continue to store your BCH, you’ll still retain full, exclusive access to these funds, which will always be accessible with your recovery phrase. Still curious about how Bitcoin Cash will work in the Blockchain wallet? Visit our Support Center.
