7 Decentralized Home Mining w/ BitAxe Decentralized Home Mining w/ BitAxe

Some Topics We’ll Cover Some Topics We’ll Cover History of Bitcoin Mining How BitAxe Decentralizes Mining Hardware and Software Requirements Electricity Costs and Efficiency Comparison BitAxe Supra Setup ● Connecting to a solo pool ● Running a Bitcoin Node w/ Knots ● Configuring C-Lightning for Bolt 12 Payouts ● Connecting to Ocean.xyz via DATUM – Configuring DATUM for Pooled or Solo Mining

9 History of Bitcoin Mining History of Bitcoin Mining Evolution: Bitcoin mining has grown from CPUs to GPUs, FPGAs, ASICs, and ultimately, large industrial facilities. As mining technology has advanced, so has its complexity and centralization. Check out the bitcoinminingmuseum.com

10 History of Bitcoin Mining History of Bitcoin Mining Resurgence of Home Mining: Hardware like the BitAxe brings mining back to individuals, lowering barriers to entry and supporting open source innovation and decentralization. Make ASICs Great Again

11 Home Mining in the Current Environment Home Mining in the Current Environment ● Challenges: The high costs of ASIC hardware and increasing network difficulty can discourage solo miners. ● Opportunities: Affordable devices like the BitAxe are empowering individuals to mine Bitcoin, participate in network security, and promote decentralization. Hashrate ATH

12 Pooled Mining Pooled Mining Purpose: Pooled mining enables collaborative work, leading to consistent payouts. Miners can use platforms like Ocean.xyz or public-pool.io for solo or pooled mining with independent block template preferences. Some common payout schema: ● Pay-Per-Share (PPS): Fixed payout per valid share, ensuring stable income, but no bonuses for lucky periods and no transaction fees included. ● Pay-Per-Last-N-Shares (PPLNS): Payouts based on shares contributed in the last N shares when a block is found, leading to more volatile earnings, with potential for higher payouts. ● Pay-Per-Share Plus (PPS+): Combines PPS for block rewards with PPLNS for transaction fees, offering stable payouts with potential extra earnings. (viabtc.com) ● Full Pay-Per-Share (FPPS): Similar to PPS, but includes transaction fees in the payout for more comprehensive earnings. (brains.com / foundrydigital.com) ● TIDES (Transaction-Based Incentive Distribution System): A reward system that adjusts payouts based on individual shares, reducing variance and offering more transparent and predictable rewards. (ocean.xyz) Block Rewards, Fees, Shares, and Luck

13 Solo Mining (Lottery Mining) Solo Mining (Lottery Mining) Solo mining offers full control over earnings but results in infrequent rewards. This setup is ideal for miners seeking self-sovereign operation. Solo mining is when a miner works alone to solve blocks, competing with the entire network. ● Reward Structure: The miner gets the full block reward only if they solve a block, with no intermediate payouts. ● Probability: Success depends on their hash rate compared to the network's total, making wins rare. ● Advantages: Full control, no pool fees, and maximum decentralization. ● Challenges: High risk due to payout delays and low chances without significant hash power. ● Tools: OSMU projects such as the BitAxe offer an accessible DIY solo mining solution at a low cost point while maintaining self-sovereignty, decentralization, and optimization. Test your luck! Compete with the entire network!

14 Some Recent Solo Mining Wins Some Recent Solo Mining Wins Improbable but not impossible – 12 blocks solo mined in ‘24 so far..

15 StratumV2 Protocol StratumV2 Protocol Benefits: StratumV2 improves security and efficiency by giving miners more control over block templates such as through miner-side template providers. Some pools that support StratumV2: ● Dmnd.work ● BRAIINS.com Stratum V2 is still in early stages os adoption

16 DATUM - DATUM - Decentrailized Alternative Templates for Universal Mining Decentrailized Alternative Templates for Universal Mining Functionality ● DATUM lets miners create custom mining templates directly on their Bitcoin node, supporting both solo and pooled mining.
