Bitcoin Open-Source Development Takes The Stage In Nashville

Published

on



Caught up in the storm of price action and US politics, it’s easy to forget the Bitcoin technology landscape had its own breakout earlier this year. Now that things have cooled off over the summer, next week’s Open-Source Stage at Bitcoin Nashville is a good opportunity to survey the industry’s progress.

Looking at this agenda, this year’s stacked lineup should be able to provide some signal amidst the electoral chatter. To warm us up for what promises to be an absolute marathon of an event, I’ve highlighted a handful of topics and talks to keep an eye on.

Technical innovation

Bitcoin builders will be looking to pick up on the momentum generated around “Bitcoin Season 2” in Nashville as the focus will remain on efforts to unlock Bitcoin’s programmability.

I previously discussed the arms race over all things BitVM and other purported layer 2s. The level of excitement around Bitcoin script has never been so high. Progress enabled by previous soft forks like Taproot and SegWit has led to various experiments, most motivated by the Ordinals craze. Naturally, the conversation has started to revolve around what comes next.

Unlocking expressivity with OP_CAT

Friday, July 26. 9:30 AM

Base58’s founder and everyone’s favorite Bitcoin educator Niftynei (Lisa) will look to set the tone on Friday morning by chairing a panel on the popular soft fork proposal OP_CAT. The hype around the script improvement proposal has not subsided and Bitcoin developers have been increasingly vocal about their affinity for CAT and its superpowers.

I expect co-panelists Andrew Poelstra, Director of Research at Blockstream, and fellow developers Rjindel & Brandon Black to make a strong case for the versatile script improvement.

BitVM: Pushing innovation without a soft fork

Friday, July 26. 10:00 AM

It’s hard to overstate the sheer brain power assembled in this talk. There is a reason BitVM has been the talk of the town since developer Robin Linus brought it onto the stage last year. The proposal has managed to attract an impressive crowd of builders and thinkers fascinated by the prospect of bringing fraud-proofs to Bitcoin.

With no working implementation yet, it also feels like crunch time for many of its promoters who have been talking a big game about its potential. The star-studded group of developers should be able to update us on the progress here and perhaps cut through the hype a bit.

Privacy at stake

Friday, July 26. 2:00 PM

The arrest of developers Keonne Rodriguez and William Hill in April sent shockwaves through the Bitcoin industry. Fixtures of the community for nearly a decade, both had been ardent proponents of Bitcoin users’ rights to privacy. Now that the dust has settled, questions linger about the case’s implications for open-source developers worldwide.

Veteran attorney Tor Ekeland who represented Roman Sterlingov in the high-profile “Bitcoin fog” mixer case will be joined by other panelists to discuss the US Department of Justice’s “abusive crypto prosecutions and the blockchain surveillance state.

Making Bitcoin more private with CISA

Friday, July 26. 1:30 PM

This one is a little more obscure but will likely warrant attention from the more technical-minded folks. Cross-input signature aggregation, or CISA, is a proposal that has been floated in Bitcoin circles for many years already and was once envisioned as part of the Taproot upgrade. 

The general idea is to allow transactions to combine signatures from multiple inputs into a single one, effectively reducing their overall weight, and therefore cost. The proposal surfaced back into public discourse a few months ago in the context of debates over much-needed privacy improvements to the Bitcoin protocol. Some have suggested that reducing the cost of collaborative, multi-input, transactions like coinjoin might incentivize further use of privacy tools.

Originally spearheaded by Blockstream Research, developer Fabian Jahr was recently awarded a grant by the Human Rights Foundation to research the topic further. He will be joined on stage by respected wallet developers Craig Raw of Sparrow Wallet and Jameson Lopp of Casa.

The state of Bitcoin Core development

Saturday, July 27. 11:00 AM

Bitcoin’s reference software implementation is the quiet giant of this industry. The diverse and diligent team of developers has historically preferred to remain out of the spotlight. Now that the technical space is heating up and the stakes are as high as ever, how are its contributors dealing with the increased attention?

Bitcoin Magazine’s own Aaron Van Wirdum will attempt to elucidate the inner workings of this tight-knit group and allow contributors like Ava Chow and Murch to share their thoughts on the project.

Ecash debate: what are the tradeoffs?

Saturday, July 27. 3:15 PM

I could not end this article without shilling at least one of the panels I will be involved in. Is it a replacement for centralized custodians? Is it a scaling solution? Nobody seems to agree on the role of ecash in the Bitcoin ecosystem but, if anything, it can’t be ignored anymore.

The rapid progress of projects like Fedi and the Cashu open-source implementation has garnered a significant amount of mindshare over the last year. Advocates celebrate its versatility and privacy gains while detractors claim it is no different than the banking system Bitcoin was built to obsolete.

Both sides will be represented on the panel which is shaping up to be an exciting conversation around the future of Bitcoin’s financial system.

There is a lot of excitement at the prospect of Bitcoin entering the big leagues but it’s hard to tell if the ecosystem is ready to accommodate this new influx of interest. Now that we are crossing the political chasm, it’s crucial to continue supporting the open-source culture that brought us here. Fortunately, the industry has never looked so ready to tackle this challenge. The diversity of initiatives on display at the conference is a testament to the maturing technical environment made possible by FOSS developers.

Bitcoin's Price Does Matter — A Lot

Published

on


Follow Frank on X.

Some in the Bitcoin space claim to only be in it for the tech, maintaining that bitcoin’s price doesn’t matter much to them. 

Whether they’re just posturing or whether they really mean it, they’re overlooking a major factor that keeps the Bitcoin network secure and healthy — the price of bitcoin.

Lyn Alden did an exemplary job describing why bitcoin’s price matters in the follow post:

Her main points included:

  • The more liquid bitcoin becomes, the less volatile and more usable as money it becomes.
  • Price is a market signal: five years of stagnant price action would send a negative signal to the market about bitcoin’s value.
  • If bitcoin (a finite asset) was designed as a counter to fiat (an infinite asset), its price should increase as more liquidity is injected into the system (i.e., as more fiat is printed or more debt is created).

I’d like to help further Lyn’s argument by including the following points:

  • The security of the Bitcoin network depends in large part on the amount of people or institutions that mine bitcoin. As the block subsidy decreases every four years, bitcoin has to continually increase in price for miners to remain incentivized to mine the asset.
  • Bitcoin’s price adds to its legitimacy: the closer bitcoin’s market cap gets to the market cap of gold, the more investors view the assets as comparable.
  • An increase in bitcoin’s price incentivizes holders to continue to do things to keep the network healthy, like running nodes, and to defend the network against its detractors. After all, as Jeff Booth says, “We Are Bitcoin,” and its success depends on us.

So, if you were pumped when bitcoin’s price hit a new all-time high this week, good for you.

Even if you weren’t necessarily thinking about the points made above as bitcoin’s price reached new highs, it’s also okay to simply be happy about having greater purchasing power.

Coinbase Is Embarrassing Itself By Not Buying Bitcoin

Published

on


Really, at this point, Coinbase is just embarrassing itself by not buying Bitcoin and doing silly buybacks.

Coinbase just had a bad quarter. After reporting disappointing Q3 earnings, its stock plunged over 10%. To instill confidence, Coinbase announced a $1 billion share buyback. But that flopped, too, with shares barely budging.

This whole debacle just shows that Coinbase is foolishly ignoring the obvious strategy here — buying bitcoin.

Instead of share buybacks, imagine if Coinbase put $1 billion into bitcoin for its corporate reserves. That would have sent a real message. It would show they have skin in the game and truly believe in Bitcoin and crypto’s future.

Let’s be clear – Coinbase should be all-in on Bitcoin’s upside. This is the industry they pioneered! Yet here we are in 2024, and Coinbase won’t follow the proven Bitcoin reserve model that is literally being flaunted in their face by MicroStrategy.

Look, I am not any financial engineering expert to tell public companies what to do, but it’s just too evident for crypto companies at this point.

MicroStrategy started buying Bitcoin in 2020. And look what’s happened — their market cap now exceeds Coinbase’s! This software company, with 1/10th the revenue of Coinbase, has surged past the OG Bitcoin and crypto exchange. All thanks to stacking sats.

How embarrassing for Coinbase! They’ve been around since 2012, when Bitcoin was $5. Just imagine if they went all-in on BTC back then. But it’s still not too late.

No more wasting money on share buybacks or lame projects. The solution is staring Coinbase right in the face — just keep stacking sats!

It’s painfully obvious at this point. Any self-respecting Bitcoin and crypto company must hold Bitcoin on its balance sheet. It aligns interests with shareholders and strengthens credibility.

So wake up, Brian! No more excuses. Coinbase literally owes its existence to Bitcoin. It’s time to go all in at last.

The Whitepaper: The Simplest Ideas Are The Most Profound

Published

on


It has now been sixteen years since the original publication of the Bitcoin whitepaper on the cryptography mailing list. Satoshi went and dropped the paper in the place it would be best received, where all of the cypherpunks and cryptography nerds who had been obsessed with digital cash systems for years hung out and regularly discussed that and other related topics.

The whitepaper was by no means even close to a comprehensive description of the Bitcoin protocol. It didn’t describe the scripting language at all, it didn’t go into a difficulty adjustment algorithm, it just vaguely described the concept of one. It didn’t define the exact protocol blocks were propagated across the network with (just a vague description), or the difference between consensus and policy rules. It didn’t define an issuance schedule or a total supply, just that it could be finite at some arbitrary value and eventually end issuance to support the network based solely on fees.

None of the actual implementation details or specifics of the actual system were described in any way whatsoever. Just the general concept of a proof-of-work secured blockchain and how it could function without a central third party taking the role of record keeper for the transaction history to prevent double-spending.

This is still a rather profound document given all of its shortcomings when weighed against the Bitcoin protocol itself in totality. Applying proof-of-work with a difficulty adjustment to the double-spend problem is the profound breakthrough that actually differentiated Bitcoin from prior attempts at digital cash, such as bitgold or e-cash.

While the whitepaper itself is by no means close to enough information to reimplement the protocol as it stands today, it is enough to replicate a similar enough system. It’s the heart of it, the bits that really had to exist for the protocol we know to be brought into the world. Despite its lack of details and specificity, it will stand the test of time as one of the most important academic papers released in the 21st century.

Everything brought into the world starts with an idea, and the ideas in this paper are truly profound in the implications and consequences they have had, and will continue to have on the world around us.

Happy Whitepaper Day.
