Mining revenue hits structural lows as hashprice sinks, costs rise and payback periods stretch past 1,000 days, squeezing even the largest operators. The Bitcoin mining industry has entered what may be its most severe economic downturn in its 15-year history, with even large publicly traded operators struggling to break even amid collapsing mining revenue and rising debt, according to TheMinerMag. In its latest report, TheMinerMag said miners are operating in the “harshest margin environment of all time,” as hashprice — the revenue earned per unit of computing power — has fallen from an average of about $55 per petahash per second (PH/s) in the third quarter to roughly $35 PH/s, a level the publication characterized as a structural low rather than a temporary dip. The deterioration followed a sharp correction in the price of Bitcoin (BTC), which fell from a record high near $126,000 in October to below $80,000 in November. Read more

Buterin warns that quantum computers could threaten Ethereum’s cryptography sooner than expected and outlines how the network can prepare safely. Buterin sees a nontrivial 20% chance that quantum computers could break current cryptography before 2030, and he argues that Ethereum should begin preparing for that possibility. A key risk involves ECDSA. Once a public key is visible onchain, a future quantum computer could, in theory, use it to recover the corresponding private key. Buterin’s quantum emergency plan involves rolling back blocks, freezing EOAs and moving funds into quantum-resistant smart contract wallets. Read more

Eclipse combines high-throughput execution with Ethereum settlement in a way no other L2 has attempted. Cointelegraph Research breaks down the architecture and the milestones that will define its trajectory. The majority of Ethereum rollups have converged on a single model, in which the EVM is still the execution engine. So parallel execution remains a vague ambition rather than a feature of most Ethereum L2s. Eclipse takes a different path. It brings the Solana Virtual Machine into an Ethereum-anchored environment and restructures the rollup stack around it. The latest report by Cointelegraph Research examines how this design emerged, the problems it solves and what questions it raises for the broader layer-2 ecosystem. It highlights where Eclipse diverges from existing rollups and why these differences matter for developers, users and institutions. Read the full report here to explore Eclipse’s architecture, economics and path toward verifiable rollup status. Read more
