At the recent State of Digital Money event in Los Angeles<\/a>, Bitcoin scaling was the topic of conversation for a panel consisting of Airbitz<\/a> CEO Paul Puey<\/a>, derivatives trader Tone Vays<\/a>, Yours<\/a> CEO Ryan X. Charles<\/a> and Bitcoin Core<\/a> contributor Eric Lombrozo<\/a>. During the panel discussion, each participant was able to share his vision for how Bitcoin should be scaled to handle a much larger userbase.<\/p>\n

For Lombrozo, scaling Bitcoin is about getting the greatest gains in terms of throughput increases while also limiting the amount of risk and security vulnerabilities involved in those improvements.<\/p>\n

\u201cObviously, if you have just a few entities that are validating the transactions for everyone, then that creates a point of attack or a single point of failure,\u201d said Lombrozo. \u201cPart of the whole philosophy of Bitcoin is you should be able to validate your own transactions.\u201d<\/p>\n

Lombrozo added that scaling Bitcoin means users are able to validate their own transactions without necessarily being forced to validate everyone else\u2019s transactions as well.<\/p>\n

\u201cThat\u2019s the trick,\u201d said Lombrozo.<\/p>\n

An example of this method of scaling Bitcoin is the Lightning Network<\/a>, in addition to other Layer 2 protocols.<\/p>\n

From Lombrozo\u2019s perspective, using a blockchain for every transaction is like going to court every time a deal is made with a counterparty. The Lightning Network allows users to interact directly rather than dealing with the blockchain as a third party of sorts to process the transaction.<\/p>\n

In the past, Joseph Poon<\/a>, who is a co-author of the original Lightning Network white paper<\/a>, has shared similar comments related to the use of Bitcoin\u2019s underlying blockchain as a court for smart contracts.<\/p>\n

\u201cInstead of viewing [the blockchain] as simply a payment system, if you view it as a smart contracting system, which enables the blockchain to act as a dispute mediation system, viewing the blockchain as a judge is a lot more understandable and a lot more powerful,\u201d said Poon at the 2016 MIT Bitcoin Expo<\/a>.<\/p>\n

Lombrozo added that second-layer protocols like the Lightning Network act as a sort of paper IOU to bitcoin\u2019s gold \u2014 except in the case of the Lightning Network, the user knows they will always be able to redeem the paper for gold.<\/p>\n

In addition to Layer 2 protocols, Lombrozo would also like to see different signature schemes implemented in Bitcoin to lower the resource requirements of operating a full node. Schnorr signatures<\/a> are an example of such an improvement that has been in development for Bitcoin.<\/p>\n

Another key point made by Lombrozo during the panel discussion was that different players in the Bitcoin ecosystem desire different features in the protocol; for example, long-term holders may not care as much about $10 on-chain transaction fees as those who have built businesses around the use of the blockchain for coffee purchases or other low-value transactions.<\/p>\n

In summary, Lombrozo referred to a user\u2019s ability to only need to validate their own transactions (while still remaining secure) as the \u201clow-hanging fruit\u201d of scaling Bitcoin.<\/p>\n

Yours CEO Ryan X. Charles<\/h3>\n

While Charles claimed he was happy to see progress made on the eventual activation of Segregated Witness<\/a> (SegWit) via the activation of BIP 91<\/a>, he also added, \u201cSegWit doesn\u2019t go far enough.\u201d<\/p>\n

From Charles\u2019s perspective, SegWit will not sufficiently lower on-chain transaction fees, which he sees as the key issue for users at this time. In his view, much lower on-chain transaction fees are needed for mainstream adoption of Bitcoin to occur.<\/p>\n

According to Charles, the main disagreement between various parties when it comes to the best way to scale Bitcoin has to do with how much transactional activity should happen on the blockchain, as opposed to secondary layers of the network.<\/p>\n

\u201cI am very much in favor of radical increases to the block size,\u201d said Charles.<\/p>\n

Charles added that it would take 30 years to send every person in the world a bitcoin transaction with the current 1MB block size limit.<\/p>\n

\u201cThat just doesn\u2019t work from the point of view of mainstream adoption of bitcoin,\u201d said Charles.<\/p>\n

Charles also noted that the Lightning Network white paper stated that a 130MB block size limit would be necessary for mainstream adoption to be possible, even with various Layer 2 scaling options.<\/p>\n

According to Charles, the key question to answer is: How does Bitcoin get from 1MB to 10GB blocks?<\/p>\n

\u201cComputers get faster and cheaper,\u201d said Charles. \u201cIt doesn\u2019t just have to be technical software and cryptographic optimizations.\u201d<\/p>\n

Derivatives Trader Tone Vays<\/h3>\n

When Vays spoke about his vision for scaling Bitcoin, he first noted that the digital cash system may not be able to do all of the things that were promised in the early days. He specifically mentioned privacy, security, instant transactions and cheap payments as examples of features that were promised by Bitcoin enthusiasts back in 2013.<\/p>\n

\u201cIn reality, having all of those things at once is almost impossible,\u201d said Vays. \u201cThere\u2019s a chance Bitcoin can\u2019t do all that.\u201d<\/p>\n

Vays reiterated Lombrozo\u2019s point about different users wanting different features in Bitcoin. In his view, the censorship-resistant properties of the system should be viewed with the highest level of priority.<\/p>\n

\u201cThe reality is a censorship-resistant payment method is way more important,\u201d said Vays. \u201cYou have so many other ways to pay for your cup of coffee, but you don\u2019t have a lot of ways to donate to Wikileaks. You don\u2019t have a lot of ways to buy \u201cother\u201d things…\u201d<\/p>\n

Last year, Vays published a post on his blog<\/a> where he examined some of these use cases involving censorship resistance.<\/p>\n

Vays added that he trusts the current group of contributors to Bitcoin Core, the reference implementation of the Bitcoin protocol, to focus on this priority of censorship-resistant digital cash.<\/p>\n

For Vays, the next area of focus for developers after the activation of SegWit should be privacy-focused improvements, such as MimbleWimble<\/a> and Confidential Transactions<\/a>.<\/p>\n

Airbitz CEO Paul Puey<\/h3>\n

Before talking about anything else, Puey stated that he is very much for the activation of SegWit. However, he then shared his belief that much more on-chain capacity is needed on the Bitcoin network, as Charles had previously stated.<\/p>\n

\u201cWe\u2019re not going to be able to live with a 1MB block, and it was an arbitrary number,\u201d said Puey.<\/p>\n

Puey added that computers are now four to five times more powerful than when the block size limit was originally added to Bitcoin by the system\u2019s creator. He also indicated that the correct \u201cmagical number\u201d to define the block size limit is hard to figure out, which is why he believes the free market should decide.<\/p>\n

\u201cI don\u2019t think the developers should make that decision,\u201d said Puey.<\/p>\n

Puey did not elaborate on how the free market would be able to make this decision. It\u2019s unclear if he was talking about Bitcoin Unlimited\u2019s concept of emergent consensus<\/a> or simply users choosing between different blockchains with different block size limits.<\/p>\n

The Airbitz CEO then prefaced the rest of his comments with the fact that he still has a tremendous amount of respect for the people who have been contributing to Bitcoin Core over the years as they\u2019re trying to solve an incredibly hard problem.<\/p>\n

Puey noted that he, as a developer, knows his limitations when it comes to developing a proper user experience for software applications.<\/p>\n

\u201cHow many of you people want the developers designing the user experience of your protocol, your application [or] your website?\u201d Puey asked the audience.<\/p>\n

In Puey\u2019s view, the idea that every Bitcoin user is going to run their own full node, even at a 1MB block size limit, creates a flawed user experience and will prevent the technology from being adopted by the masses.<\/p>\n

\u201cEvery party in this debate wants decentralization, but they all define it differently,\u201d Puey added.<\/p>\n

While Puey suggested that more users running their own full nodes is helpful, he also shared his belief that having greater adoption of bitcoin as a currency would also help the system become more resilient to attackers.<\/p>\n

\u201cThe more people that are using it, the more that the economy is dependent on it, the harder it is to stomp out a technology,\u201d said Puey.<\/p>\n

Puey concluded his response to the scaling question by stating that he was happy to see BIP 91 help end the stagnation in the adoption of protocol improvements.<\/p>\n
