UASF Revisited: Will Bitcoin’s User Revolt Leave a Lasting Legacy?

Attention this week has so far focused on a group of bitcoin users that successfully split off the blockchain to form their own cryptocurrency.

But fascinating as the real-time market creation has been, for those who have closely watched developments, August 1 marked another lesser-acknowledged milestone – the passing of the deadline for a controversial scaling proposal Bitcoin Improvement Proposal (BIP) 148.

That’s when a vocal group of users were hoping for a so-called “Independence Day.” The goal was to push through a long-stalled coding optimization called Segregated Witness (SegWit), designed to increase and redefine the network’s capacity. The software upgrade would find node operators (users who store transaction history) initiating the move, hoping to lead the way for miners and startups.

And while it’s faded a bit into the background, you could argue that, even amidst a busy season for scaling proposals, BIP 148 was perhaps the most influential.

The scaling “agreement” Segwit2x followed soon after, proposing to add a feature that BIP 148 wouldn’t have provided: a boost to the block size. Bitcoin Cash was even more explicitly a response to BIP 148 – hence, why both were scheduled for the same day.

But the proposals had one other thing in common, and that was giving power over the software transition to the miners that secure the blockchain.

Before its introduction, for example, SegWit had stalled for months due to its reliance on the idea miners would signal support by running the software. However, only about 30 to 45% of mining pools did so.

Then, suddenly, two weeks before the scheduled UASF, and with little time to spare, mining pools rallied around Segwit2x, a proposal that would activate SegWit.

Unsurprisingly, UASF supporters don’t see this as a coincidence.

Blockchain startup founder Ragnar Lifthrasir, a public UASF proponent, told CoinDesk:

“UASF worked as designed and predicted, it is activating SegWit.”

Balance of power

It’s a narrative that adds evidence to the idea that changes to the bitcoin protocol (and perhaps all public blockchains) are destined to be political.

As ethereum classic and bitcoin cash have now proved, there’s capital to be created in splits. The more nuanced argument is that they also seek to aid research and understanding of the science behind blockchains (though with economic risk to users).

In bitcoin, it could be said the scaling debate has called to mind the shaky balance of power between its major network participants – startups, miners, developers and users. And the argument continues to be that UASF was a movement of the people, one that like any social revolution, was perhaps destined to be feared by the powers that be.

While bitcoin users may be predisposed to such narratives, it’s certainly one that has resonated with supporters.

“We found out that not just miners, but some VCs and bitcoin startups didn’t like the power of users, that’s why they came up with Segwit2x, to obscure UASF’s success and precedent,” Lifthrasir he said.

He argues that it was a question incentives. Mining pools didn’t want to risk that their 12.5 bitcoin block rewards (worth approximately $33,000 today) would be rejected, but they didn’t want to support the UASF effort.

“This means hashing power follows nodes and users, not the reverse,” Lifthrasir argued, and he isn’t the only UASF supporter to feel this way (or that this is important).

“Basically, BIP 148 was an early success,” remarked Bitcoin Core developer Luke Dashjr, a UASF skeptic who later turned into one of its more ardent supporters.

Lasting impact

In the end, BIP 148 was sidestepped by another network proposal. But it’s the mere threat of action, supporters argue, was enough.

Calin Culianu, a developer for Bitcoin Cash, the version of the bitcoin protocol boasting 8MB blocks, even agreed that Segwit2x was likely a response to BIP 148 on some level.

Although, Culianu has a different way of thinking about it, arguing that BIP 148 supporters used scare tactics to make it sound like it had more support than it did.

“Miners got antsy, people got scared and everyone met in New York to hash out a plan,” he said, alluding to how Segwit2x was originally determined.

The question now seems whether this tactic is good for development.

Academics, for instance, have long argued against the sometimes visceral and knee-jerk decisoin-making that seems to take place in the blockchain industry – and the UASF could be seen as a problematic continuation of this trend.

Culianu almost seesawed on the question of whether UASF was a good thing for his project, as it could be said it spurred the “big block movement” to action.

He concluded:

“UASF was the spark that made all this happen, for better or for worse.”
