As an analyst with a background in cryptocurrency and blockchain technology, I find Vitalik Buterin’s blog post on the Bitcoin block size debate to be a fascinating exploration of the historical nuances that divided the Bitcoin community. Having closely followed this debate as both a participant and an observer, Buterin offers unique insights into the contrasting narratives presented by Jonathan Bier’s The Blocksize War and Roger Ver and Steve Patterson’s Hijacking Bitcoin.
In a recent blog post, Ethereum founder Vitalik Buterin delved back into the significant Bitcoin block size debate that deeply split the Bitcoin community between 2015 and 2017. By immersing himself thoroughly in two influential books, Buterin re-explored the complexities of this rift from a distinct viewpoint as both an active participant and a respected thought leader within the crypto sphere.
In Buterin’s blog post titled “Some thoughts on the Bitcoin block size controversy,” he explores the distinct perspectives presented in Jonathan Bier’s “The Blocksize War” and Roger Ver and Steve Patterson’s “Hijacking Bitcoin.” These books encapsulate the small-block and large-block advocacy groups, respectively, offering insights into the ideological and technical rifts that defined the contentious discourse.
Bitcoin Small Blockers Vs. Big Blockers
As a researcher studying the evolution of Bitcoin, I’ve gained valuable insights from Bier’s book regarding the perspective of small blockers. This group, dedicated to preserving Bitcoin’s decentralized and user-accessible nature, strongly opposed large increases in block size. Their concern was that larger blocks would necessitate more powerful hardware for node operators, potentially centralizing the network to those who could afford such resources.
A notable quote emphasized by Buterin conveys this apprehension: “With larger block sizes, you would necessitate a substantial data center to operate a node, making it infeasible to do so anonymously.” Furthermore, according to Buterin, small-scale miners were depicted as strongly committed to Bitcoin’s current governance structure.
Instead of frequent modifications decided by a few key players, they opted for rare adjustments that required consensus. The New York Agreement of 2017, aimed at resolving disagreements over block size through collaboration among major exchanges, miners, and other influential groups, was deemed antithetical to the decentralized governance principles of small supporters, who advocated for decision-making power in the hands of the broader community rather than a select corporation.
From my perspective as an analyst, the story presented by big blockers, as depicted in Ver and Patterson’s research, portrays a faction dedicated to preserving Bitcoin’s role as “digital cash.” This group expressed disappointment over the transformation of Bitcoin into merely a “store of value” or “digital gold,” which they believed deviated from Satoshi Nakamoto’s original vision set forth in the whitepaper.
Buterin articulated the pro-large-block perspective, stressing that expansive blocks are crucial for maintaining affordable transaction fees and encouraging broader usage of Bitcoin for routine transactions. The supporters of larger blocks, in contrast to their smaller counterparts who advocate for layer 2 solutions like the Lightning Network, criticized these alternative methods as they do not expand block sizes but rather aim to manage transaction volumes differently.
According to Ver and Patterson’s perspective, these proposed solutions came with intricacies, necessitated constant internet access for users, and lacked the capacity to handle the international demand without simultaneously expanding the Bitcoin block size.
Contemplating his perspective, Buterin disclosed a complex viewpoint. At first, he leaned toward understanding the arguments of the big blockers due to their valid concerns regarding high transaction fees threatening Bitcoin’s usefulness. However, over time, he grew displeased with both sides for their unwillingness to find a middle ground. He stated:
From my perspective, the larger group held valid concerns regarding the central issue of increasing block size. They advocated for a straightforward hard fork, as originally proposed by Satoshi, to address this issue. However, the smaller group made fewer technical blunders and had less extreme positions that could result in unintended consequences when followed through logically.
Buterin’s Lessons For Ethereum
Buterin champions a moderate standpoint, placing importance on “reasonable certainty” when it comes to transaction fees and node responsibilities. He showcases Ethereum’s methods as a model, demonstrating how Ethereum has implemented gradual enhancements in block capacity alongside fee modifications to skillfully manage expansion and scalability.
As a researcher exploring the advancements in blockchain technology, I was dismayed to notice the absence of significant discussions surrounding technological innovations like ZK-SNARKs. These technologies hold great promise in addressing scalability and privacy concerns without requiring contentious compromises. By embracing new technologies, we can potentially deescalate political tensions by providing solutions that cater to the interests of diverse stakeholder groups. In my perspective, Vitalik Buterin’s suggestion is a prudent one worth considering in our ongoing efforts to improve and evolve the blockchain ecosystem.
As a researcher studying the evolution of cryptocurrencies, I was surprised and intrigued by an apparent oversight in both books I recently read. The term “ZK-SNARK” was completely absent from their pages. By the mid-2010s, this technology had already gained significant attention for its potential to address scalability issues and enhance privacy. Zcash, which is built upon ZK-SNARKs, was launched as early as October 2016.
Buterin’s blog post isn’t just a look back at a disputed period in Bitcoin’s past, it also acts as a warning for Ethereum and other blockchain projects. He emphasized the need for open governance and continuous technological advancement to prevent “exclusive competence traps.” In simple terms, having a limited range of abilities and viewpoints can hinder progress and result in deep-rooted disputes.
Buterin expressed his interest in studying Bitcoin’s triumphs and setbacks not with the intention of belittling Bitcoin to boost Ethereum, but rather because numerous communities, including Ethereum and those he holds dear, can significantly benefit from gaining insights into what transpired, what functioned effectively, and what could have been improved.
