Ephemeral Rollup: The New "L1.5" of Ethereum

In briefEphemeral Rollup: a new L1.5 architecture for Ethereum (Ethereum Research forum discussion)

SummaryThe post proposes an "L1.5" pattern in which users keep their state in their wallets, L1 holds shared state and verifies every transition, and the computation in between is done by parties that hold no state needed for the next job, with results settled directly on L1. It relies on proposals such as EIP-8141, EIP-8250 and EIP-8288 to argue the pattern is becoming practical, using private settlement as the main example. It also distinguishes the pattern from rollups.

Information hazards and safe redaction

In briefInformation hazards and safe redaction: a Bitcoin developer forum post on giving users a way to safely remove data they do not want to store or spread.

SummaryThe author argues that subjective information hazards can be written to the blockchain and that there is currently no general defence against this. They propose discussing ways for users to safely redact data they consider hazardous while keeping most functions of a full archival node, and ask for others working in this area. The discussion explicitly excludes restricting arbitrary data from being published in new blocks.

The Long Road to Bitcoin Payments

In briefThe Long Road to Bitcoin Payments: Why adoption lags and calls for bold ideas to change it

SummaryThis Delving Bitcoin community discussion examines why bitcoin payments have not taken off despite improved payment technology such as Lightning. It argues the main obstacle is weak demand, notes that major payment providers are choosing stablecoins, and points to price volatility as a barrier. The author invites readers to propose moonshot ideas that could shift bitcoin payments and calls on builders, payment providers, and funders to contribute.
