SEC Commissioner Hester Peirce drew a sharp line around decentralized finance on Sept. 17. She said investors need no exemption to use permissionless smart contracts for peer-to-peer trading. The SEC and CFTC actions examined here set separate limits on intermediary control.The unresolved question is how much control a software provider can retain before it begins to resemble a regulated intermediary.Peirce’s statement expressed her own position. A binding definition from the US Securities and Exchange Commission would require Commission action. The SEC’s tokenized-securities order and a separate staff statement leave her phrase “truly decentralized” undefined. Their specific provisions focus on custody,…

Ethereum’s institutional data hub showed about $120 billion in staked ETH and $40.4 billion in daily average total value locked on layer-2 (L2) networks in a Sept. 21 snapshot.They measure different things: ETH committed to network security and assets held across L2 networks, so adding them together would not measure fresh ETH demand.Meanwhile, US-traded Ethereum ETF sessions saw over $140 million in net outflows from Sept. 15 to 18. Large pools of staked ETH and assets on Ethereum-linked networks can coexist with investors pulling money from a particular investment channel.A staking balance is not a purchase receiptStaking involves depositing ETH…

Some Bitcoin mining vardiff (variable difficulty) controllers can keep demanding work calibrated for a machine’s former speed after it cuts hashrate. The miner can keep hashing and consuming electricity while accepted shares become vanishingly rare.Bitcoin Optech highlighted the failure mode on Sept. 18, drawing wider attention to an analysis that mining engineer Eric Price published in July. The finding concerns pool-assigned share difficulty, not Bitcoin’s network difficulty, and it describes a testable controller weakness rather than evidence of widespread miner losses.How Bitcoin mining vardiff gets stuckPools assign each connection a share difficulty that is easier than Bitcoin’s block difficulty. A…

A coordinated attack drained 8.7 million FET and used a compromised NuNet minter key to create 408.5 million NTX.The Sept. 19 attack emptied the Ethereum-side conversion contract used by SingularityNET’s bridge, removing 8,721,530 FET worth about $1.55 million at the time.

The company said the affected infrastructure belonged to SingularityNET, primarily its Ethereum-Cardano bridge, while Fetch.ai’s own contracts and…
