Fabian Jahr and Gloria Zhao rejoin me to discuss whether big projects can be done inside Bitcoin core. We delve into AssumeUTXO, ASMap, developer funding, and meritocracy in the developer community. Summary In this episode, Stephan discusses the upcoming Bitcoin Core version 28, its new features, and the ongoing development efforts with Fabian and Gloria. They delve into the pace of change within Bitcoin Core, the importance of communication and collaboration in software development, and the challenges faced by developers in getting projects approved. The conversation also covers the AssumeUTXO project, its implications for node operation, and the significance of funding and competing implementations in the Bitcoin ecosystem. The episode concludes with insights into future projects and the collaborative nature of Bitcoin development. Takeaways Bitcoin Core version 28 introduces exciting new features. The development process involves both small bug fixes and significant changes. Communication and collaboration are essential for project success. AssumeUTXO allows for quicker node synchronization. The decentralized nature of Bitcoin development presents unique challenges. Funding can influence project focus but should not dictate it. Competing implementations can complicate backward compatibility. Iterative development is crucial for large projects. Engaging the community early can lead to better outcomes. Future projects like ASMap and Cluster Mempool are on the horizon. Timestamps: (00:00) - Intro (00:32) - What to expect from Bitcoin Core V28.0?

In this episode with Bitcoin Core dev Gloria Zhao we discuss: Second generation immigrant pursuing grant-funded development over job at Google, Meta, etc. The verifiability of Bitcoin Do we have enough nodes around the world? Block scarcity Is Bitcoin really nation-state resistant and unhackable? Should people put all their money into Bitcoin? Financing core devs and incentives Can AI or quantum computing crack Bitcoin? Will there be another Block Size War? GLOSSARY: Bitcoin Core: Software considered the reference implementation for the Bitcoin protocol. It is the continuation of Satoshi Nakamoto's original bitcoin software released in 2009. Block: A block is a record in the blockchain that contains transactions. Roughly every 10 minutes, on average, a new block is appended to the blockchain through mining. Block Size: The amount of data that can be stored in a block. This size is limited to maintain the efficiency and integrity of the blockchain. Node: A computer that connects to the Bitcoin network. Private Key: A private key is a piece of data that proves your right to spend bitcoins from a specific wallet through a cryptographic signature. UTXO: Unspent Transaction Output - An output that has not been sent to another address. The bitcoin wallet balance is calculated from adding up unspent outputs. ---- BIO: Gloria is one of the maintainers of Bitcoin Core, primarily focused on the peer-to-peer protocol. Her projects include package relay (BIP 331) and TRUC (BIP 431), aimed at reducing censorship vectors and fee-bumping inefficiencies in transaction relay.

37 The Life of a Bitcoin Core Developer w/ Gloria Zhao In this week's episode of Bitcoin Bottom Line, hosts C.J. Wilson and Josh Olszewicz are joined by Gloria Zhao, a Bitcoin core dev to break down the behind the scenes action of a developer. Wilson begins by asking “what got you into Bitcoin in the first place?” To which Zhao responds, “... There are a lot of ideologies in there from the beginning that I found very appealing, and on top of that there are a lot of very interesting engineering technical challenges to work on, and as a computer science student obviously I was drawn to that...” She continues, “I grew up in Silicon Valley so I think that gave me perspective on how endless it is to chase this idea of ‘innovation' and profit, and that always struck pretty empty to me so Bitcoin was very different and I had an immediate draw to it.” Olszewicz then asks, “what is your day to day like? Zoom calls and meetings or do you work independently as a decentralized developer?” Zhao answers “...I work on Bitcoin core, which is one implementation of a Bitcoin client,... Day to day I'd say save a few community, cultural, changes it's kind of just like working on any software project, except we don't have a boss, we just kind of review each others PR's cause we care about them and they are important to Bitcoin, we fix bugs because if they stay in the client then the network might have some troubles, not because our boss told us to..” To follow this up Wilson asks, “what's the percentage of time you spend, let's say reviewing other people's work, having conversations with other people about what you guys are working on vs. just going into the rabbit hole yourself and doing more of a deep dive?” She responds that because of the nature of her work, she keeps a detailed breakdown of her time – “about 30% of my time on my main project... I try to do about 50% of my time on just peer review, and or opening small PR to fix bugs... about 10% of my time on things like advocacy and education,... and 10% just pure learning.” She goes on to say, “I very much value time like this where you are able to send a message ... I can tell people, hey there's people working on Bitcoin, hey it's gonna break if nobody works on it, so it's really important to pay the people who do, and get more people to want to be Bitcoin core developers, because that is very important for Bitcoin's health developmentally.” Discussing personal securities, Zhao details, “We live our lives online and there is a lot at stake and a lot to lose... I think everyone should learn how to code a little bit, or equip themselves with tools to protect themselves on the internet.” Continuing on the discussion of security in regards to Bitcoin, Zhao explains, “We care about operating in this system because there are legitimately people who need money in these systems, and other alt coins where they are not operating under that threat model, and maybe they are doing something or solving an interesting technical challenge that is useful in other aspects, but they don't have what I think is Bitcoin's core value proposition which is its security model.” Zhao finishes the episode with “it is going to be built brick by brick, where everything is stable underneath, so we need more people.” Listen to the whole episode for more! #Bitcoin #crypto #JoshOlszewicz #Valkyrie #BBL #Bitcoinbottomline

In informatica un post mortem è un paper analitico che descrive cosa non ha funzionato in un dato sistema. Un documento simile, focalizzato sull'ecosistema TERRA/LUNA, ci dice con chiarezza cosa non andrebbe MAI fatto.Inoltre parliamo di Gloria Zhao, sviluppatrice di Bitcoin Core, della sua proposta per trasmettere pacchetti di transazioni, e della nuova legge presentata in USA che si propone di regolamentare l'intero mondo delle criptovalute.Lift off Bipers!!!!

On this episode of the Unhashed Podcast, Do Kwon doubles down on the Luna scam, Raoul Pal tries to squirm out of accountability for promoting it, Gloria Zhao proposes a long-anticipated update to mempool policy, Adam Neumann of WeWork infamy aims to put carbon credits on the blockchain, and we assess the relative acting skills of different bored apes.

In this episode of The Van Wirdum Sjorsnado, hosts Aaron van Wirdum and Sjors Provoost discussed Bitcoin mempools, Child Pays For Parent (CPFP) and package relay. Package relay is the project that Gloria Zhao will work on as part of her Brink fellowship, which was announced earlier this week, and would make the Lightning Network more robust (among other benefits). Mempools are the collections of unconfirmed transactions stored by nodes, from which they forward transactions to peers. Miners usually select the transactions from their mempools that include the highest fees, to include these in the blocks they mine. Mempools can get full, however, at which point transactions that pay the lowest fees are ejected. This is actually a problem in context of CPFP, a trick that lets users speed up low-fee transactions by spending the coins from that transactions in a new transaction with a high fee to compensate. Tricks like these can be particularly important in the context of time-sensitive protocols like the Lightning Network. In this episode, van Wirdum and Provoost explained how package relay could enable CPFP, even in cases where low-fee transactions are dropped from mempools, by bundling transactions into packets. And they explore why this may be easier said than done.
