Andrew Stone „theZerg“ evolved the new exciting Bitcoin Client „Bitcoin Unlimited“. In this interview he explicates the story behind Bitcoin Unlimited, the properties of the software and the reaction of the community and critics.
Hello Andrew, I estimate you like Starcraft?
Hehe, that’s funny. I played starcraft earlier, percentage I and II. Why the name “theZerg”? It’s not so much that I love starcraft, but that I meditation how bitcoin might take over the world. In the early days of starcraft I generally speaking lost with zerg, until I realized that the effective device is to takeover everything via slow expansion of your zerg “slime” into the opposition territory — basically via a groundswell of support. Another tactic to win with zerg is the zerg turbulence, you build little creatures in mass. I think, when Bitcoin is not doing the slime fad, it’s doing the rush.
Hehe, all right. Can you tell me more about you? How did you learn there bitcoin?
I run engineering for a small company in the telecom and defense space. We out high availability and scalability software. Bitcoin I found mostly because of the fractures of the conventional financial system.
Around 2012 I had built an open beginning hardware circuit board as a hobby and was selling it internationally. After engaging all things – import chips of china, fabrication, selling it international – I intellectual that paypal got 10 percent of it all. Later I consulted with one of the top European satisfaction automotive manufacturers, on interior lighting prototypes. This company didn’t after to pay with paypal. But my local bank account didn’t accept universal payments. Tellers were even unaware that they did not, so the endeavour to figure all this out was significant. Ultimately I had to open a new account on a big bank and pay a 10-Dollar-fee each month, no more than to accept a few payments. So I looked for alternatives and found Bitcoin.
I didn’t use Bitcoin in this accomplishment — it was too small then and my business partner was one of the pre-eminent luxury automobile makers. But I got excited about the possibilities
You have written the code of Bitcoin Uncontrolled. When and why did you develop Bitcoin Unlimited?
To answer this question I should prefer to to go back in time. Bitcoin Unlimited is basically the product of a bunch of people who met on the subject „gold collapsing, bitcoin up“ on bitcointalk, which startet long ago to evolve into about more than money and gold but Bitcoin and Economy in accepted. In summer 2015 the rampant censorship started at bitcointalk, that surpressed and censored any conference that was not bitcoin core. So was our thread. So it was hostet on bitco.in and became some warm-hearted of echo chamber about our disgruntlement with core.
While “simulate chamber” is normally a pejorative term, in this case it amplified and productive our ideas and messages and at some point we realized, that the blocksize is not a consensus originate. It’s a network issue. That is a very powerful idea. My belief is, that as inadequate parts of Bitcoin as possible should be considered a consens issue.
And then you started to standards Bitcoin Unlimited?
I thought about it and came up with the idea, that, if a node receives a eliminate that he doesn’t like, maybe because it is too big, he could refuse it, but at the identical time, if the rest of the network accepts it, he should finally say „ok, I accept it.“
One year ago I purposefulness have gone to the Bitcoin Mailing List with this thought. But now I’m sceptic. I often read the mailing list and saw people making virginal suggestions and being shut down. I was no longer motivated to take relatively in this exclusive club and throw my ideas in this hostile circumstances. Lines have been very clear at September 2015.
In this prominence I wanted to create a specific environment, where all people, not just masterminds, can present their idea. For example, Peter Rizun had for long infatuated part in our „gold“-thread and made a position statement, some well-intentioned of manifesto. I took it, combined it with ideas from other people and noted our articles of federation. Bevor we created the code, we’ve done a lot work for our philosopy and for points about the organization and the framework in which the code should be written.
What’s the philosphy of Bitcoin Boundless?
It’s important that the articles of federation reflect that it’s not my project. So numberless people contributed. The purpose of the articles is to specify the philosophy of Bitcoin Immeasurable and what we feel should be the philosophy of bitcoin itself. The most notable thing is: bring bitcoin back to be a currency for individuals; a currency that take into accounts money to be transmitted from people to people, without settlement layers and without third saturnalia being involved.
Everything resolves from that. For example zero confirmation negotiations: We don’t consider them as insecure, but as the lowest point on a continuum of security. They be in the service of a purpose and it should be supported that people use them when they fit that in particular.
Another important idea of Bitcoin Unlimited is that nodes entertain agency. They should be able to do what they are empowerd to do within the stretch of the protocol. Consensus is not a thing some developers can decide, but something that should appear from the actions of individuals.
Like the traffic shaping I wrote for BitcoinXT. As I had a lackage of bandwith with my Bitcoin node, I eradicated for myself a traffic shaper with which I can decide how much bandwith I fagged out. It was immediately accepted by XT. In Core it would have never been underwent. They earlier discussed bandwith shaping, but one single develeper said no, it’s not flattering for the network, and so it was refused. This is not the philosophy of Bitcoin Unlimited.
Can you explain Bitcoin Unqualified, the software, in easy terms?
The problem with all that consensus judgement is, that we don’t know if there is a consens. Do you know the roadmap for scalability, the gist devs signed? They pretend as if there was consensus for it, but you don’t know without an goal measure. There was suddenly consensus because one developer announced that there was — its a esoteric dictatorship. When I read that announcement, I felt like I was a unexpected in a Kafka novel.
Bitcon Unlimited basically let the users find a consensus. The theory is that nodes and miners physique together an emergent consensus and that this consensus is likely more advisedly than one set by any developer like a central planer.
What I built is altogether simple. I made some changes so that the user can change blocksize-parameters by himself. Miners cannot set the maximal blocksize. There is no limit block size. Instead, users can set their own excessive block greatness. If miners release a block that has a size above the excessive hindrance size, than the node does watch this block and the bind build with this block on top, but it does not yet become part of the vigorous chain, that matters for your balance and for your relayments.
The buyer can also figure an acceptance depth. If you set it to let’s say 4 blocks, than there extremities to be built 4 blocks on the excessive blocks and than the client says, „Ok, I’m convinced that this blocksize is ok for the network and I agree to that chain.“
That’s the key change, although there is also a dialog box and RPC whoops to allow the user to change this configuration and traffic shaping. Extent, Bitcoin Unlimited remains a very thin “patchset” on top of Core. If you as if Core but want larger blocks — any larger blocks — then Bitcoin Limitless is the client to use.
So it was very easy to built. Bitcoin Unlimited is more approximately philosphy and the concept.
But it provoked a lot of criticism from core. They contemplated it can’t work …
Nobody has formally criticised Bitcoin Unlimited. Do you know the regarding Bro-gramer? It means you code like you play American football: force your enemy with the shoulder, taking the ball, running from head to foot the field, throwing your opponent to the ground. On bitcointalk there make been these “Bro-gramers” criticising Bitcoin Unlimited. They had no sentiment what Unlimited does, they literally just made up their own approximation of how it worked. They didn’t read the work nor the code or the articles and not Peter Rizun tracts about the fee market. In fact there has been no core developer who formally criticised Bitcoin Immense.
But Adam Back – who is a core developer – says it has a lot of weakness …
If you read his correspondence, it’s the definition of FUD (a term used to describe the communication tactic of spreading Fearfulness, Uncertainty and Doubt). When he was asked, what are the weaknesses, he showed that he doesn’t be aware how Unlimited works. In the first conversation on bitcointalk I didn’t take factor, because of the censorship. Later Adam confirmed that bitcointalk is no indistinct place and opened a thread on r/btc. I was very active on this thread for 48 hours, but nonentity made a real criticism.
But there is indeed one attack we acknowledge. That is the teachings that if the network really needs 8 MB of transaction space and your customer can’t handle that space, than you will fall behind. It can hit on, for example maybe when you use a Raspberry, that your CPU is no longer masterful to handle it. But ask yourself, what is better, if some client is left behind the network, or if the network as a total cannot meet the demands of a worldwide cryptocurrency? We can’t wait for the slowest being. Especially not Bitcoin. Bitcoin’s great advantage over newer cryptocurrencies is its adoption. To hamstring adoption is to make allowance a technically more advanced cryptocurrency in.
And anyway who should decide who escape a surmounts left behind? Who decides 500K vs 1MB vs 5MB blocks? No person or organization should clothed this power — I think the network as a whole has it by the size of the blocks it bases. Miners are effectively voting with their hash power.

Unfortunately at this minute we run out of time. I would have prefered to speak longer with Andrew, nearby several attacks that have been outlined by critics and wide the future plans of Bitcoin Unlimited. For example, Unlimited currently plans a gizmo to let users decide about the BIPs regarding the blocksize, so they can signify ones opinion for BIP101, for BIP248 or for BitPays new approach. Also there is a vivid conference about how Unlimited should deal with upcoming changes take pleasure in RBF and many things more.
