Bitcoin Layer-2s & BitVM (2025): Can BTC Become a Smart-Contract Chain? Post-halving miner rewards dropped to 3.125 BTC per block and fee dynamics became make-or-break. At the same time, Ordinals/Runes waves and “Bitcoin L2” experiments exploded. This operator-first guide compares BitVM, drivechains (BIP-300/301), sidechains like Liquid/Rootstock, Stacks with sBTC, emerging rollups research, and the everyday

DePIN Tax & Accounting: Tracking Revenue, Power Cost, and Depreciation Without Losing Your Mind Running decentralized physical infrastructure, GPUs for compute, disks for storage, radio hotspots, bandwidth relays, means you’re a tiny utility company with crypto rails. That’s cool. It also means real accounting: revenue recognition, cost allocation, depreciation, inventory/basis, realized gains, and clean documentation.
Shared Sequencers Explained: Why Rollups Care and How Rewards Flow Rollups promised cheap, fast transactions secured by a base chain, but most still rely on a single, often centralized sequencer to order transactions. Shared sequencers are the next step: a neutral, decentralized ordering layer multiple rollups can plug into. They aim to improve liveness, censorship
