2026-04-24 Paul Sztorc - eCash - BTC Fork

April 24, 2026Original source

On April 24, 2026, Ernest Hancock hosted Paul for a wide-ranging discussion of eCash, the planned BTC fork, Drivechain, BIP300/301, smaller L1 blocks, optional sidechains, privacy, merge mining, and peer-to-peer digital cash.

Highlights

Key Takeaways

Drivechain As User Choice

Paul presents Drivechain as a practical answer to developer capture: users can move to optional L2 environments with different rules, features, and block sizes while the base chain remains minimal. Instead of forcing every user into one scaling or privacy model, BIP300/301 lets developers compete through sidechains and lets users select the chain that fits their purpose. That framing turns disagreement over block space, privacy, and applications into a market of live options, where the main chain supplies settlement while sidechains supply experimentation and high-throughput utility.

eCash And The BTC Fork

The eCash discussion centers on why a BTC fork can immediately reach existing Bitcoin owners while creating room for features that are hard to add directly to Bitcoin L1. Ernest presses for the concrete user benefit: private, cheap, fast peer-to-peer money without accounts, phone numbers, or legacy banking chokepoints. Paul connects that goal to Drivechain-style optionality, including privacy-oriented L2s, broader block space, and a launch path where BTC holders receive eCash exposure and can decide how they want to use or value the new network.

merge mining And Bitcoin Lineage

Paul ties Drivechain and eCash to early Bitcoin design history by discussing Namecoin, BitDNS, and Satoshi's role in merge mining. The point is that multiple blockchains secured alongside Bitcoin were part of the early design imagination, not a departure from it. merge mining lets miners support additional chains while continuing their normal Bitcoin work, and Blind Merged Mining extends that idea toward sidechains with distinct features. This gives Drivechain a clear lineage: Bitcoin security, optional networks, and market-driven functionality can reinforce each other.
