A New Look for Bitcoin Cash Addresses

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

Q: Why do my Bitcoin Cash addresses look different?

A: Bitcoin Cash developers have proposed a new format for addresses to help differentiate between bitcoin and Bitcoin Cash addresses, called CashAddr. This updated format only changes how your Bitcoin Cash addresses are displayed, not the underlying private and public keys.

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

A: We want to continue improving the user experience for both bitcoin and Bitcoin Cash within users’ wallets. Ultimately, having a different address format for each will help you distinguish which currency you’re transacting with, allowing you to use BTC and BCH more easily.

Q: What is the difference between the address formats?

A: Bitcoin Cash addresses now look like this: qp3wjpa3tjlj042z2wv7hahsldgwhwy0rq9sywjpyy. They can also have a prefix (bitcoincash:qp3wjpa3tjlj042z2wv7hahsldgwhwy0rq9sywjpyy). Each Bitcoin Cash 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 between 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 show Bitcoin Cash addresses in this new format. The only thing we encourage you to do is to start 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 begin using the new version. Don’t worry, if you have a legacy address that is currently being used, it will continue to work. If you continue transacting with your legacy addresses, they will be displayed in your transaction feed as the BCH CashAddr address equivalent.

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

A: Nope.

Q: Where can I dive into more technical details?

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

An Update on This Morning’s Twitter Changes

Early this morning (GMT time), we discovered that our Twitter account was defaced with provocative and distasteful political propaganda. We quickly got to work securing access to the account, removing the offensive tweets and broadcasting a message that all Blockchain services, including wallets and API were not impacted whatsoever. Unfortunately, we were not the only firm swept up in this issue. As this article notes, Forbes, BBC North America, Amnesty International, the European Parliament were among the hundreds of accounts impacted.

Twitter acknowledged the incident in a statement to Gizmodo stating:

We are aware of an issue affecting a number of account holders this morning. Our teams are working at pace and taking direct action on this issue. We quickly located the source which was limited to a third party app. We removed its permissions immediately. No additional accounts are impacted. Advice on keeping your account secure can be found here.

What we know is that a third party social media analytics provider called The Counter, which many large firms (including Netflix, YouTube, Slack, the UN and Adobe) rely on, was compromised. We will no longer be using them. At no time was Blockchain the deliberate target of this external breach. Here is what they had to say:

While the motivation for this bizarre social media attack is still unknown, we’re sorry for any confusion or offense this may have caused. We take these issues extremely seriously and have already kicked off an internal audit of our security practices for both our analytics providers and also specifically our social and community channels to prevent a similar incident from happening again.

Blockchain’s Wallet App for Android is Picking Up Steam

Blocktrain.org recently did an interview with Blockchain Android Wallet product lead, Keonne Rodriguez. Here’s a peek into what went down. Make sure to read the full interview over on Blocktrain!

“The goal of the Android application from the start was twofold. Update what was a dated and rather spartan UI, and more importantly prepare the ‘under-the-hood’ foundations for much bigger updates going forward. With those goals in mind we wanted to maintain feature parity and also create a new experience we felt old and new users would appreciate.”

Prepare Yourself – The North American Bitcoin Conference is coming

亲爱的 Blockchain 用户,

千万别被钓鱼!Blockchain 是钓鱼欺诈者热衷的目标。钓鱼欺诈的方式,是搭建一个外形酷似 blockchain.info,却使用不同域名的伪造站点。而攻击的触发方式则是用户不经意间的域名错误拼写、点击电子邮件中的链接,甚至通过各种网络广告平台直接推销伪站。一旦您在伪站上尝试登录 Blockchain 的服务,他们将截获您的用户名与密码(以及你的双重验证码)。由此,他们便可以窃取您的所有资金。
