HandCash is a number one pockets supplier for the Bitcoin SV ecosystem that’s finest recognized for its pioneering approaches to make Bitcoin as person pleasant as doable. Different digital foreign money app builders have already been greater than impressed by HandCash’s design.
CoinGeek’s Michael Wehrmann caught up with Alex Agut, Rafa Jiménez and Ivan Mlinarić from HandCash to speak about Bitcoin app design, inter-wallet competitors, Bitcoin computation and extra.
Hi there Alex, Rafa and Ivan! Kindly introduce our readers to what HandCash is and what function every of you fulfill within the HandCash staff.
Alex Agut: I’m one of many co-founders and CEO at HandCash, and my roles are principally product design and coping with the enterprise facet: elevating cash, advertising and marketing and paperwork.
Rafa Jiménez: I’m the (different) co-founder and CTO at HandCash. I’m accountable for the technological selections to meet the imaginative and prescient of our firm, present the sources to our improvement staff in addition to create and implement our staff tradition. Additionally I do a bunch of coding, in fact!
Ivan Mlinarić: I’m the senior software program engineer. Joined nearly a 12 months in the past. I’m accountable for our cloud infrastructure and area data/logic.
HandCash’s web site slogan is “Bitcoin for the remainder of us.” What does it imply?
Alex Agut: Whereas others have been making an attempt to please the cryptocurrency crowd for the final 10 years, we really feel our place on this ecosystem is to make this expertise extra accessible and priceless for the remainder of the world.
HandCash is finest recognized for its astonishingly easy person interface. Some months in the past, we’ve seen a well known BCH pockets supplier—with far more funding than you’ve gotten—roughly copying your complete UI. Is there any method for HandCash to guard its UI in opposition to blatant copying?
Alex Agut: No. In reality, we predict it’s a robust constructive sign that corporations all around the world are our firm for management by way of usability, design and mindset. We maintain innovating and we’ve issues in improvement that are years forward of something on the market—subsequent time it’ll take a couple of years for others to catch up—however they may attempt. You’ll see what I imply.
What does it inform us if a well-funded BCH pockets supplier really pays consideration to your creations? Are you setting new requirements for digital foreign money apps generally?
Rafa Jiménez: Innovation means offering new merchandise which can be accepted. It type of validates the work our staff is doing. We are literally engaged on the following iteration of digital foreign money. We’ve got seen bank cards, then we had PayPal and the following technology is HandCash with Cloud Cash to become profitable extra linked and accessible. So new expertise requires new requirements.
Ivan Mlinarić: We prefer to give attention to a handful of issues we see as vital however not correctly addressed on this planet of digital currencies. If others later copy us that normally means we had been proper about it.
Alex, you’ve gotten tweeted that copying a design isn’t the identical as really creating it, as there may be extra to design than simply design selections on the floor. Kindly elaborate on that.
Alex Agut: I imagine that design is about how issues work, not how they give the impression of being. In case you are blindly copying the position of buttons and screens, with out realizing the “why” behind these selections, you’ll by no means perceive the essence of your product. The UI is simply the end result of your intent, your goal. There’s a course of behind it.
How is HandCash really creating wealth? And the way do you propose on making much more cash?
Alex Agut: To be trustworthy, our solely supply of revenue in the mean time is our merchandising, because of an exclusivity settlement with Zeroconfs.com, however we’ll begin monetizing in a extra significant method very quickly by way of Connect, some neat fiat ramp techniques and different stuff. On the similar time we understand monetizing or not at this stage gained’t transfer the needle one bit as this business is barely beginning and there are nonetheless lots of improvements wanted to get to a degree the place we are able to market this confidently to regular folks.
HandCash and Cash Button not too long ago shocked Bitcoin SV customers with an enormous press launch regarding the implementation of an inter-wallet peer-to-peer collaboration. Kindly introduce our readers to this implementation and the implications of that.
Rafa Jiménez: It was an awesome announcement! Utilizing the Bitcoin community has turn into the usual method for the wallets and providers to speak to one another. This method is very costly for providers with many customers that use their wallets continuously as we have to always monitor every transaction within the community to seek out out which one is related for our customers.What we introduced was a special communication channel based mostly on Paymail, so the totally different pockets suppliers can talk to one another instantly (P2P) as an alternative of utilizing the Bitcoin community totally. The Bitcoin community ought to be reserved only for the miners. That is simply a part of the unique recipe of Bitcoin.Ivan Mlinarić: IP2IP transactions are one thing that was a part of unique Satoshi’s bitcoin shopper. However after he left performance was eliminated, as a result of it was by no means totally carried out. Yesterday we had been joking we at the moment are fulfilling Theymos’ imaginative and prescient as a result of there may be an outdated thread on bitcointalk the place core builders determined to take away it from the code base. And Theymos was the one one in favor to fairly end it. He was overruled. If you understand his function later within the small block and everybody must run a full node debate it’s a fairly fascinating learn.
Our fundamental motivation right here is to go P2P as quickly as doable as that is primarily a scalability answer. We can’t afford that one single enterprise adopts BSV and surprises us with a number of site visitors on the BSV community. One massive entity can actually kill nearly all of the apps working now on Bitcoin when it generates a number of site visitors. Recipe on tips on how to resolve the scalability difficulty was already set by Satoshi. We selected to increase paymail, as a result of paymail already solved what was lacking from Satoshi’s implementation and we really simply wanted so as to add the half he did implement. Cash Button did a incredible job right here for us, we’re very grateful.
I discover this collaboration attention-grabbing, as a result of I assumed HandCash and Cash Button compete for a similar customers. Is Bitcoin incentivizing companies to collaborate in new methods aside from within the non-Bitcoin world?
Alex Agut: Personally, we don’t take into account Cash Button our competitors, in order that makes issues straightforward. We is likely to be making an attempt to succeed in the identical viewers proper now, however as time passes and the viewers will get larger (the pie grows) the variations can be extra noticeable. I even suppose they are often two nice complimentary merchandise and ecosystems, so we’ll see.
Given our friendship, we’ve mentioned many instances about our shared want of transferring away from non-P2P to a P2P form of community, because it ought to (simply learn the title of the whitepaper). So each of our groups determined to hitch forces as we each had a really related objective, and it will be a win-win for each of us. We’ve got extra to lose by not having P2P in Bitcoin when coping with different providers, and Cash Button is by far our greatest “bridge” of transactions (outdoors of HandCash to HandCash) so it made a lot sense to cowl most of our transactions underneath P2P as quickly as doable. This can be notably crucial after we launch Join as a part of the HandCash ecosystem.
Assist us perceive how pockets suppliers really compete within the Bitcoin SV ecosystem. Is there an incentive for pockets suppliers to let customers change to different providers simply, or is there an incentive to “lock in” customers? Taking a look at Twitter, Google, Amazon and many others., they’re primarily all “locking in” customers in a method, as a result of in any other case their enterprise fashions wouldn’t work. Customers won’t even need to have a number of pockets suppliers or change providers generally although, however have one which meets their calls for completely properly. What are your ideas?
Alex Agut: There are lots of sides to that. Whereas Bitcoin fans (or “followers”) cheer for interoperability of keys and freedom of motion, each from the enterprise and improvement facet issues look loads in a different way. There’s a giant incentive to create and develop your community impact, and in addition there are immense benefits of getting a customized pockets infrastructure that’s not suitable with others: flexibility for brand new options, elevated safety, method much less errors, drastically much less help tickets… so it’s not a matter of making an attempt to “lock down”, we are able to’t.
You’ll be able to all the time ship your Bitcoin away by utilizing paymail, or cashing out to your financial institution. We will’t and we gained’t maintain anyone hostage. However does it make any sense to export your non-public key and many others. to a different pockets infrastructure and trigger UTXO sync points to each corporations and make double spends simpler to tug off, when you’ll be able to simply transfer your cash away and get a csv with all of your transactions from that service? We expect that’s simply the outdated, geeky method of doing issues, however doesn’t essentially create the very best merchandise. We’re not dogmatic about Bitcoin, we’re simply utilizing it as a software to create nice merchandise that folks love and discover priceless.
Rafa Jiménez: We agree with Ryan X. Charles and different entrepreneurs within the area on making the pie larger as an alternative of making an attempt to monopolize the ecosystem. The probabilities proper now are infinite, so competing for a similar factor would even be a joke.
I’ve a robust opinion on interoperability. Regardless of being a fascinating characteristic, it’s very costly: many various corporations should agree on the identical technique to function. It hinders innovation as you’ll be able to’t change the way in which to function even should you discover extra environment friendly or extra refined methods.
We should be good about managing the interoperability/innovation barrier, particularly within the rising interval we at the moment are! That is why our collaboration with Cash Button has lots of worth.Ivan Mlinarić: The large benefit for a Bitcoin powered pockets is it that firm constructing it may well save lots of operational prices and enjoys the decreased barrier to entry as a result of a startup doesn’t must construct a really costly closed customized ledger after which spend a number of cash on securing it (internally and externally). This half is usually solved from day one and corporations can take pleasure in aggressive benefit over these which aren’t on this place. However Bitcoin is inherently a public ledger, so the second you contact it you’re coming into the interoperable world. Customers can all the time ship cash to totally different wallets.However there are additionally different financial incentives. We cooperate with different wallets and POS suppliers as a result of speaking instantly to one another is the one method we are able to effectively scale whereas utilizing enough privateness and make the most of superior options Bitcoin supplies.
Is it mistaken to say your inter-wallet P2P implementation helps Bitcoin SV to scale, or no less than helps the Bitcoin SV apps to scale?
Rafa Jiménez: That’s proper. The P2P community between customers and providers will not be related for the miners in any respect. So it is a measure to assist functions to scale, or in different phrases to scale the applying layer.
Ivan Mlinarić: It’s not mistaken in any respect. It’s precisely that.
So far as I perceive, this P2P implementation is between providers, not essentially between clients and retailers. Is that right?
Rafa Jiménez: Nice query. This implementation supplies some form of transaction notifications between providers. On the time one service “notified” different providers a couple of transaction, such a transaction was already despatched to the miners.Within the customer-merchant context, on the time the transaction is shipped from the client to the service provider it has not been seen by the miners but, as a result of they want to ensure they agree on sure standards for the transaction like the precise quantity to pay or the charges.The context for the implementation we supplied doesn’t must implement these guidelines. It’s simply folks sending suggestions to one another or folks transferring their funds between totally different providers.
Ivan Mlinarić: Sure, that is only a easy push transaction protocol between providers/wallets/customers. Important use case we had in thoughts after we designed it was microtransactions. However that doesn’t imply it doesn’t work properly for bigger transactions, too. It is extremely much like BIP270 which covers service provider funds, however will not be that. It’s a separate simplified protocol.
Is HandCash working for B2C transactions to be “extra SPV” sooner or later, too?
Rafa Jiménez: HandCash Cloud is versatile sufficient to introduce new parts as SPV. So in case our infrastructure wants to make use of SPV, it gained’t be an issue. These days it’s an method that provides little or no or no worth to our stack: our system all the time has web connection and the communication with the miners is “free.”
Ivan Mlinarić: We’re already engaged on implementing miners service provider API which principally covers us to completely make the most of SPV. However the primary problem will not be the SPV half, however the way in which transactions are delivered. That’s the reason we focus extra on P2P now and fewer on SPV. However they each work hand in hand to resolve scalability points.
Allow us to speak about Bitcoin computation generally. Cash Button’s Ryan X. Charles said that, “Bitcoin goes to be by far the most important pc ever (…) And what you are able to do with the most important pc on this planet is: you’ll be able to really compute larger numbers.” May this “Bitcoin pc” theoretically be capable to compute something that HandCash is true now doing on different providers regarding the backend?
Ivan Mlinarić: Who is aware of. In the intervening time this seems like sci-fi. We’re utilizing business vast adopted applied sciences that are secure and properly examined. We use Bitcoin as a ledger which can also be secure and properly examined. Beginning to transfer greater than that at this time limit to “Bitcoin pc” can be a suicide and super threat as there are such a lot of unknowns and we might utterly lose give attention to what we need to obtain now.
In case it’s theoretically doable, is it proper no longer handy sufficient for Bitcoin SV apps to take action? Are transaction processors (so referred to as “miners”) not but specialised sufficient to compute your backend on-chain or in one other method?
Ivan Mlinarić: Relies on the app. There’s all the time an area for experimenting. However we don’t see there may be any infrastructure we may really make the most of. We additionally don’t need to be the one constructing it from scratch.
HANDCASH LABS SL. is a Spanish firm, proper? Are you able to inform us how European knowledge safety legal guidelines set by the GDPR are affecting HandCash?
Alex Agut: Sure, our firm is predicated in Spain. Positive, we work with a London-based regulation agency, Baker McKenzie. Is without doubt one of the high regulation companies on this planet, they usually crafted our privateness coverage and assessed our staff so we’re compliant with the newest guidelines. They are going to be periodically reviewing this in case we have to replace our insurance policies and practices to adjust to regardless of the regulation requires.
HandCash lets customers join with their cellphone quantity. Is that for KYC causes? Does it additionally enhance customers’ security in a method?
Alex Agut: There are lots of causes for this. First, sure, we take very significantly that as we’re coping with cash, we have to and need to know the actual identification behind each single one among our customers. Second, it allowed us to have our business first 2FA system for a non-custodial pockets. Third, it would enable for some cool options sooner or later, however, proper now… it’s a good way to go keyless in a pleasant, safe method. Earlier than folks anticipate.
I do know you can’t touch upon what number of customers you serve, however enable me an informed guess no less than. RelayX, one among your opponents, appears to have round 3000 customers to this point, however RelayX has launched method later than HandCash. Cash Button printed the variety of 150 companies actively utilizing it and over 1.three million button swipes to this point. My finest guess is that HandCash needs to be round 6,000-7,000 customers. Am I completely off?
Alex Agut: Received’t give numbers however you’re completely off. Far more than that. We will confidently say that nearly each Bitcoin SV person is a HandCash person. Greater than signal ups, we give attention to present, actual energetic customers—and let’s simply say we’re very comfortable about that quantity, particularly when Join is popping out this spring.
On the CoinGeek Toronto convention in 2019, Mempool’s Lin Zheming identified difficulties for pockets suppliers to succeed in Chinese language customers. What are your ideas on that, and the way do you propose to get a fair broader person base?
Alex Agut: We’re not within the Chinese language market on the time. Our apps are unlawful there so… except the CCP modifications its thoughts on permitting cryptocurrency apps over there, we gained’t be making an attempt to get in hassle with their authorities by distributing APKs or TestFlight betas in China to bypass their legal guidelines – code will not be regulation. We love the Chinese language folks and their enthusiasm for this expertise, however that is out of our management. If the scenario modifications, we might love to assist the Chinese language folks entry Bitcoin by way of HandCash.
In a latest hangout with the Bitcoin SV Channel, you talked about how HandCash relies on the Bitcoin SV ecosystem’s development. How may HandCash attain customers except for the Bitcoin SV ecosystem? Is it doable so that you can supply non-Bitcoin associated providers to individuals who don’t need to use Bitcoin?
Alex Agut: To a level. We expect we’re one of many least dependent corporations on this small ecosystem on the destiny of what others do—we love to do issues our method and have as few dependencies with others as doable. We’ll attain common folks by making an interesting product—and notion can be key. We’ve got a couple of methods up on our sleeves, some will name them advertising and marketing stunts, and they’re in a method. However we predict it would work for us, and others are invited to hitch our motion. Why would we provide fiat or crypto providers when Bitcoin is the very best cash on the market? Folks simply don’t realize it but. And there are explanation why that is that method, and there are methods on which we are able to change that notion. Wait and see!
There’s extra to HandCash than simply the pockets offering service. On the CoinGeek London convention in early 2020, you launched HandCash Join. Kindly introduce our readers to what HandCash Join is.
Rafa Jiménez: It goes past a pockets, for certain! We envision an ecosystem of connected apps and video games the place folks can spend and earn cash doing what they love. HandCash Join is a Bitcoin SDK. The quickest and versatile technique to construct apps on Bitcoin. It’s wonderful, as a result of it permits startups to create new enterprise fashions utilizing the highest options of Bitcoin with out having to cope with all of the jargon that takes months to study. Additionally they’ll reap the benefits of the identical infrastructure we use to serve hundreds of customers each day. They simply give attention to what they do the very best: creating wonderful merchandise. We handle the remainder.
Sounds promising! Thanks very a lot in your time!
Alex Agut: Thanks in your curiosity in HandCash! You actually did your homework J
Rafa Jiménez: Thanks in your curiosity in our mission!
Ivan Mlinarić: Was a pleasure!
