NOSTR đĽ
Just wanted to surface a privacy concern some of us have been digging into: timing analysis attacks on encrypted DMs in Nostr. Even though the messages are encrypted (NIP-04), observers watching a relay can correlate senders and receivers just by looking at when messages are sent and received.
This kind of metadata leakage might sound minor, but it could be serious especially when traffic is low or when people rely on only a few relays. Timing patterns can reveal communication pairs, undermining the privacy Nostr aims to provide.
Some ideas have been discussed (delays, batching, cover traffic, NIP-59), but Iâd love to hear more perspectives.
How big a deal do you think this is? Any mitigation strategies youâve seen or implemented?

Never Forget 2019 - Encryption
A thought experiment.
Imagine if:
Within the next 89 days, China, Europe, and Japan agree to go zero/zero on tariffs and remove all trade barriers.
Then Europe and Japan join China in raising tariffs on the United States to 145%.
Then China, Europe, and Japan as a united front negotiate with the U.S. to remove tariffs and trade barriers, and put in place strong structural protections for intellectual property and global supply chain stability.
Trump has signed a bill nullifying the IRSâs expanded crypto broker rule, meaning no mandatory KYC for non-custodial services.
Itâs a big win for privacyđĽ

Ironically, US policy meant to punish China may end up ceding Bitcoin hashrate dominance back to jurisdictions with fewer restrictions. Decentralization as unintended consequence.

DOJ Drops the Hammer on Crypto Crackdown
The Trump administration ends the DOJâs role in regulating digital assets, calling past efforts reckless and poorly executed. No more targeting of exchanges, mixers, tumblers, or wallets for user actions or accidental violationsâŚonly real crimes like terrorism and trafficking remain in focus.

Coinbase Is Building a Surveillance Bridge to Bitcoinâ ď¸â ď¸â ď¸
Coinbase now demands users âverifyâ their own wallets before sending Bitcoin. The intent is clear: attach legal identity to on-chain addresses. Once done, every movement of funds becomes traceable, indexed, and stored forever.
This has nothing to do with protecting users. Itâs about feeding data to regulators and enforcing KYC at the edge of the network. The irony is sharp: Bitcoin was created to remove the need for trusted intermediaries. Coinbase is rebuilding them complete with ID checks and transaction logging.
The blockchain doesnât forget. Once an address is linked to an identity, analysis tools can map behavior, associations, and history. Every coin becomes suspect. Every transaction, a dossier.
Cypherpunks didnât write code so exchanges could turn Bitcoin into a compliance layer for the banking system. Bitcoin is peer-to-peer. It doesnât ask for your ID. It doesnât care where you live or what your name is.
If you value freedom, stop using tools that betray it.
Run your own node. Hold your own keys. Use coin control. Exit the honeypots.
Bitcoin doesnât surveil people. Corporations do.
