Breadwallet CEO Aaron Voisine: SegWit Soft Fork First, Block Size Hard Fork Later

The ongoing block size dispute has catapulted to the center of attention again. One of the most talked-about developments is Segregated Witness, of which a public testnet iteration was launched last week. The innovation as recently proposed by Blockstream co-founder and Bitcoin Core developer Dr. Pieter Wuille is the centerpiece of a scalability “roadmap” set out by Bitcoin Core.


But relying on Segregated Witness as the next step of Bitcoin’s scalability process is opposed by the recently launched Bitcoin Core fork Bitcoin Classic. Rather than a Segregated Witness soft fork, Bitcoin Classic prefers to deploy a “cleaner” hard fork in order to increase the block size limit to 2 megabytes.


To find out where the development community stands on this issue, Bitcoin Magazine reached out to library and wallet developers – those who will need to do the heavy lifting in order to utilize Segregated Witness once rolled out.


In this, part 3 of a series: Breadwallet CEO Aaron Voisine.


The Other Side of Segregated Witness


Wuille’s Segregated Witness proposal is set to improve the Bitcoin network in several ways. For one, it effectively increases the block size to some 1.75 megabytes to 2 megabytes. But interestingly, many developers are more excited about the other improvements Segregated Witness has to offer.


This is true for Voisine as well.


“Segregated Witness is worth the effort even if it provided no block size increase,” Voisine said. “It has lots of advantages. The thing I think is most interesting about SegWit soft-fork technique is the ability to add new signature types such as Schnorr signatures. This means that if elliptic curve algorithms were broken, for instance by quantum computers in the future, we could fix that with only a soft fork, by adding a new quantum resistant digital signature algorithm. The fact that we get a quick, effective bump in block space is just a bonus.”


As such, Voisine plans to roll out support for Segregated Witness on the popular Bitcoin wallet app for iOS.


“The implementation is not especially difficult, and it’s opt-in for wallet developers,” Voisine explained. “Existing wallets that don’t upgrade will continue to work, they will just need to pay higher fees because their transactions will be larger than Segregated Witness transactions. With Breadwallet, we’ve started working on our implementation and should be ready to try it out on the Segregated Witness testnet over the next few weeks.”


Soft Forks vs. Hard Forks


The most notable difference between Bitcoin Core and Bitcoin Classic is that the former prefers a soft-fork increase in block size through Segregated Witness. A soft fork can be employed through miner-support only, and is therefore considered a safer solution by Bitcoin Core developers. The Bitcoin Classic team, however, believes these risks are overblown, and considers a hard fork more desirable.


Voisine said he sees merit in a soft fork as well – though he notably expressed support for Bitcoin Classic, too.


“I think we should do the Segregated Witness soft fork first,” Voisine said. “It will be quicker to achieve consensus. However, Segregated Witness will only give us something like an 80 percent capacity increase, and hard forks take a long time to deploy. The hard fork needs to be readied, and roll-out started quickly after. While I’d prefer it if Bitcoin Core does that, it appears Bitcoin Classic is the leading option for deploying a hard fork. As such, we do support that project.”


For more information on Segregated Witness, see Bitcoin Magazine’s three-part series on the subject, or part 1 and part 2 of this development series.

Why I've decided to bale on Bitcoin. (reddit.com)

Long time lurker here. Been holding BTC for the last two years since February, 2014.. until today. Yes, I’m one of those that has caused the price to drop as I sold more than half. Sorry. But all this complete and utter bs with the miners, devs and in-fighting has really illustrated to me that bitcoin really is a 1st generation cryptocurrency. I’m not a computer guy and smart like a lot of you are and I’m sure the price will probably rebound, but long term? I’m not holding my breadth. Yes…

BTCDirect: Making International Bitcoin Exchange ‘as Fast as Possible’

btcdirect

BTCDirect has a very unique bitcoin exchange platform. Unlike other exchanges, BTCDirect does not own any bitcoin. Instead, it places a bitcoin order on an international exchange once it receives payment from a customer. The goal of this model is to make international bitcoin trading more straightforward, as other options create inconvenient difficulties for traders.

We interviewed BTCDirect CEO Mike Hutting in order to learn more about the company.



 



BTCDirect: A New Way to Exchange Bitcoin Internationally


How is BTCDirect any different than other exchanges out on the market?


We position ourselves as a ‘brokerage’, meaning that we execute the orders of our users on international bitcoin exchanges. These exchanges are usually not very user friendly, have limited payment options available and it can take quite some time before you are able to buy your first bitcoins there. We really put the interest of our users first and listen to their feedback. There is simply no other service around where you can sign up and activate an account, buy bitcoins with your credit card up to 1000€ per day and receive the bitcoins in your wallet all within a few minutes.


Speed and ease of use are the two things where we really distinguish ourselves from other services where you can buy and sell bitcoins.


Why is BTCDirect directing its attention to Spanish Bitcoin customers?


Month after month we were seeing more and more Spanish users on our website, even though we didn’t really target this market yet. This made us realize that there wasn’t really a service like ours active in Spain yet. Our Spanish users told us that they really appreciate the service we offer and that we should become more invested in the Spanish market, so after a few meetings we decided to go for it.


How will BTCDirect become the most used exchange for Spanish users?


For the first time bitcoin user, we simply offer the best service around. Our live support agents are available through most of the day to help you with the activation of your account and to guide you to the order process. Within a few weeks from now we hope to have added our first Spanish speaking staff members to our support team, again increasing the user friendliness of our platform.


When we helped our first Spanish users to buy bitcoins they were able to use the payment options ‘Sofortbanking’ and a regular SEPA bank transfer. But ofcourse most Spanish people prefer to use their credit cards for online purchases so we worked around the clock for several weeks to make this possible. Now we are one of the only companies around where you can buy bitcoins with your credit card, and we are most definitively the fastest.


Why use an account activation method through Skype? 


In order to keep our platform safe and to be compliant with EU legislation it’s important for us to identify our users. We were looking for ways to make this process as simply and fast as possible. The activation through a quick video call on Skype or via the live chat window on our website has proven to be the best possible method thus far. The number of new account activations and the feedback we receive from our users seem to confirm this. The call is usually finished in under a minute and the support agent that helped you with your activation will be there to guide you to the ordering process afterwards.


An important aspect of Bitcoin is anonymity. Why force people to expose themselves through a skype call?


The only option to buy anything in full anonymity is with cash and most certainly not online. So when buying something online with your bank account or with your credit card you shouldn’t have the illusion that you are anonymous in any way. For us to be able to provide this service at all we have to be compliant with legislation and therefore we have to identify our users. Luckily for us most of our users seem to understand this and have no problem with this whatsoever.


About anonymity, bitcoin transaction are not fully anonymous but pseudo anonymous. The public ledger itself is fully transparent and most transactions can be lead back to an actual person. People tend to focus on the anonymity aspect of bitcoin but this isn’t one of the most important features about bitcoin we believe. The most important aspects are speed, cross boarder transactions, the fact that you can be your own bank etc etc.We also are strong believers of the fact that bitcoin has an important function as a hedge to the current financial system. That was basically the most important reason to start BTC Direct in the first place.


What are crucial features offered by BTCDirect?


  • – Buy and sell bitcoins instantly

  • – Receive your bitcoins in under 2 minutes

  • – Wide range of payment methods

  • – Live support

  • – Proven track record

  • – Thousands of active users


 


BTCDirect aims to become the biggest exchange in international markets through their user-friendly platform, account security measures, customer support, and dedication to their customers. Definitely, a contender to rise as one of the better exchanges available to customers in international waters. Their vision for the future is simple and straightforward, allowing us to see a bright future for the exchange. Hopefully, accompanied by success.
