The Bitcoin SV vision is to give miners a choice

In one of Satoshi Nakamoto’s early writings, it was noted that “the nature of Bitcoin is such that once version 0.1 was released, the core design was set in stone for the rest of its lifetime.” But does that mean that not a single change can ever happen?

That was the one of the questions posed by nChain CEO Jimmy Nguyen at the recently held The Future of Bitcoin Summit Bangkok 2018 in Thailand. During the two-day summit, Nguyen, along with Chief Scientist Dr. Craig Wright, addressed an audience of miners and developers to remind everyone that the Bitcoin Cash (BCH) was birthed “to restore what Bitcoin was from BTC,” and that they pooled together because they want to create “a Bitcoin protocol that we believe will fulfil Satoshi’s vision.” The full transcription of Jimmy Nguyen and Dr. Craig Wright’s speech by user cryptomic can be read here.

“We believe it’s time for Bitcoin as an entire world and ecosystem to group up and professionalize, and that’s what we’re advocating,” Nguyen said. “And what do we mean by that? What we mean by that is a protocol that is stable.”

One of the most promising Bitcoin BCH node implementation is Bitcoin SV, a project born out of the desire to empower miners so they’ll make informed decisions about critical protocol upgrades. Contrary to widely held belief, Bitcoin SV is not a fork—it will lock the “battle-tested” Bitcoin BCH protocol in place. In turn, miners will have a choice and a voice to drive the process of restoring Bitcoin to its optimal state. That of unbounded blocks and original OP_Codes.

This November, mining nodes running Bitcoin SV will enable a short list of upgrades on the BCH network, the most important of which is increasing the default maximum block size from 32MB to 128MB.

But why is it important to scale now, and scale fast in terms of block size? After some modelling with business analysts, Nguyen said the reason is simple: There’s a direct economic need for miners.

“In two years the block reward will be split in half again to 6.25 BCH. So anyone who’s mining now will in two years receive half of what they’re receiving today. In order to maintain even current profitability, what that means is in two years they have to make up that 6.25 coins worth of value in something else, which has to come in transaction fees and which has to come in higher transaction volume,” Nguyen explained.

He added, “If we have to get anywhere near 4, 16 gigabytes in two years, we can’t wait a year from now. We have to start that process now. That’s critical because otherwise in two years mining is going to become less profitable and that threatens the whole viability and security of the network if the miners cannot make up the actual revenue they need to make up in transaction volume and fees.”

Nguyen said the advocacy to scale quickly and safely was not born out of a desire for bigger blocks.

“There is an imperative economically built into the system to do this and do it now. We want to lock the original Bitcoin protocol so that businesses can reliably build on it. Professionalize the whole process with quality assurance and security audits. Promote zero-conf security,” he said. “We want to create a pathway to rapid adoption globally, and not just for payments but by the big enterprises which will lead to the miner revenue which is critical. Unless they are being profitable and making money, miners will not continue doing this after two years, and the approach we’re advocating will also lead to premium services for them, such as data, such as this property registry type venture for which they’ll get paid more money given the data capacity needed.”
