Non-standard transactions and mempool policies for BitVM Bridges

I will explain the usage of Ephemeral Dust and TRUC Transactions in BitVM bridges and how non-standard transactions makes BitVM bridges feasible.

Mining Pool Insights: Technical Analysis of Stratum V1 Templates in Aggregate

A deep-dive into Stratum V1 mining templates and what their aggregated analysis reveals about mining pool operations. From these templates, we can extract meaningful insights about pool behaviors, coordination patterns, network characteristics, and bugs.I'll give a quick break-down of the Stratum V1 protocol's "mining.notify" message structure and how visualizing this data across multiple pools can show us interesting mining pool behaviors. I'll step through ~2 different recent cases using historical Stratum V1 data to understand pool behavior and cooperation: 1. Caching bug in Antpool's coinbase transaction builder: https://b10c.me/observations/14-antpool-and-friends-invalid-mining-jobs/ 2. Solana token marketing stunt: https://x.com/boerst/status/1882429452229198021This presentation will appeal to those interested in mining pool centralization markers and the communication protocols that underpin the network today.

Analytical Data Modeling with On-Chain Data

- What is analytics engineering? - What is dbt (or similar tools), and how does it help data analysts & engineers apply software engineering principals? - Fundamental data modeling concepts, goals, and non-goals - How we use on-chain data at Foundry, including a brief pipeline & architecture overview - Build some analytical data models using Postgres and the provided on-chain datasets

Getting Transactions Mined with Sponsorship

A re-evaluation of how to sponsor transactions and get transactions into blocks. NOTE THIS IS A REMOTE TALK

Bitmain ASICs: What we know.

A dive into what we have learned about Bitmain mining ASICs (the chips) through the Bitaxe project

Stratum V2 incentives: let's find them into some benchmarks data

A presentation about data got during some benchmarking sessions of Stratum V2, and comparisons with the current protocol, Stratum.The talk focuses on the main incentives to switch to Stratum V2, for both miners and pool operators.

Business v. Protocol: Where miner incentives meet the profit motive

Rob Warren wrote the book on bitcoin mining. In this talk, he’ll dive deep into what real “miner incentives” look like and how they impact the build out of bitcoin mines across the globe.

Every Merchant A Noderunner

it's vitally important for merchants to run their own nodes, but there are some significant challenges. In this talk I’ll discuss the problem and the potential solutions. For a further deep dive, check out a summary Chris posted on twitter: https://x.com/cguida6/status/1901932123264618713

Launch Your Own Testnet

Create a bitcoin testnet where you control everything, including how fast the blocks are mined and what soft forks are enabled. Make it sharable on social media and even give yourself unlimited testnet coins so you never run out while testing your software!

Stratum V2 hands-on workshop: CPU mining sovereign templates

This is a hands-on workshop where the participants will be acting as different Sv2 Pools and Miners.Miners will run their own bitcoin nodes and do CPU mining on their own templates.Everyone will be mining on the same network, so whichever Pool gets the most hashrate wins!

Cluster mempool

I will talk about the ongoing Cluster Mempool project, which aims to rework how reasoning about dependent unconfirmed transactions in the Bitcoin Core mempool implementation work, for eviction, mining, RBF evaluation, fee estimation, and more. To motivate, I will discuss how this reasoning is done today, why that's broken, and how the cluster mempool project seeks to fix the problems with it, as well as additional benefits it may provide. Depending on interest, I can go further into implementation status, impact it will have on transaction relay policy, or future improvements that are possible.

Slipstream - Making the impossible Possible

This talk would be about the history, tradeoffs, and lessons learned regarding mining nonstandard transactions to the Bitcoin timechain in exchange for extra fee revenue. The primary focus being on relay policy rules vs consensus policy rules. - Why do relay rules exist? - Broad overview of consensus rules. - The deep history of mining nonstandard transactions in Bitcoin. - Problems of mining nonstandard transactions - Mining an invalid block - Upgrade Hooks - Forking off the network - Creating a block that attack Bitcoin miners DoS - Block propagation issues - Social issues about the use cases for Bitcoin - Private mempool and associated fragmentation - Forces to centralize mining - Benefits of mining nonstandard transactions - Fee revenue - Less restrictive use of the Bitcoin protocol (innovation) - Censorship resistance - Why Bitcoin needs independent template generating hashers - So I am sold, How would I build my own Slipstream?

Proxy Pools - Harness the Free Market to Decentralize Mining

The modern mining pool tech stack is optimized for industrial mining farms. But that is rapidly changing. With the declining block subsidy, explosion of interest in heat reuse, and renaissance in open source software and hardware it is clear that the future belongs to small scale miners. In this talk I will examine how FOSS proxy pool software can leverage free market forces to bring decentralization and privacy to the lowest layers of the bitcoin tech stack.

Intro Hashrate Accounting: Mining for the masses

This talk explores the concept of Hashrate Accounting and its potential to enhance Bitcoin privacy and expand mining operations. Beginning with an examination of the Bitcoin mining network's massive scale (600 exahashes/second), we'll discuss how hashrate marketplaces function and why miners sell their computational power. The presentation explains the role of hashrate proxies in facilitating forward privacy on-chain. Finally, we'll explain how Rigly brokers hashrate between miners and retail customers, and how we are facilitating the expansion of mining operations in areas with stranded energy.

eHash - blinded Diffie-Hellman key exchange for mining shares

presentation - A talk on the technical implementation of eHash and overview of recent development activity.

Explore Camera - Real Time 3D Block Explorer

Explore Camera transforms block data into 3D interactive visualizations. Built with Three.js, it makes RPC requests to Bitcoin Core to create navigable 3D representations of blocks and transactions. Each transaction is rendered as a spatial element, with height representing value and position showing block structure. Designed for researchers and developers, Explore Camera offers a new approach to understanding Bitcoin's block structure and emphasizes how much it has evolved.
