A post-quantum Lightning proposal would cost nodes ten times the bandwidth
PQLN adds ML-DSA and ML-KEM to Lightning's gossip, transport, invoices and onions without a consensus change. The on-chain parts stay classical, and the author names bandwidth as the real price.
Stream compression cuts an Ethereum node's inbound gossip by a quarter
A research post measured Teku traffic on mainnet: keeping Snappy's history across messages removes repeated topic strings and attestation data, with the same decoder bound.
SEC staff: buybacks on functional networks are not managerial promises
New Corporation Finance answers classify liquid staking receipts, define what a receipt is, and draw a line between buybacks on working and unfinished crypto systems. They carry no legal force.
Adopting ZIP-215 verbatim would make Solana's System Program ID a signable key
SIMD-0376 now specifies the cofactored equation from Taming the many EdDSAs plus explicit rejection of non-canonical encodings and small-order A and R - because ZIP-215 alone accepts the all-zero pubkey.
Bitget lost $387.5m without anyone stealing a private key
Attackers spoofed transaction data so that legitimate-looking transfer approvals drained hot and warm wallets. The haul includes about 103 million XRP; the CEO points at North Korea.

Four chains spent today deleting things
A Bitcoin clause, Ethereum's refunds and bloom filters, a Solana failure ordering, an XRPL reporting gap. Today's protocol work was subtraction and clarification.
Sequans sells its last 314 BTC and leaves the treasury strategy entirely
The French semiconductor firm once held more than 3,200 BTC; it used the sales to clear convertible debt and returns to its IoT business.
