__Spark's cascading exit problem__ Note: I'm publishing this as a technical discussion. Appreciate correction if needed. This is premature analysis based on protocol specs alone, no tests or live data to validate the mechanics yet. A previous leaf owner broadcasts their stale exit tx at zero cost. Spark Operators must counter-broadcast the current owner's exit to defend, which spends the root UTXO on-chain, confirming the branch transaction and all its outputs. If a tree has N leaves (say N=50 for a moderately sized tree), all N holders must broadcast their own leaf-level exit transactions to claim funds from the now-confirmed branch outputs. That's N on-chain transactions from one free broadcast. The attacked user bears the highest fee burden. Their exit chain includes the heavy branch transaction (N outputs) plus possible CPFP to beat the timelock deadline. Siblings each pay for just one small leaf transaction. Not catastrophic. Funds are recoverable but 1 free broadcast forces N users on-chain, with the attacked user footing the largest bill. No penalty mechanism for the attacker. The coupling is architectural: one root backs many leaves, one exit kills the tree. #Bitcoin #Spark #Layer2 #asknostr #plebchain

🚨 Observing a lot of oversimplification around multisig lately. 🚨 People confidently explaining setups they've clearly never actually configured _or_ recovered from. If you've never done a dry-run recovery of your multisig, you haven't tested your backup. Seeds, xpubs, descriptor, derivation paths, key ordering. Add all that to your backup _and test it_ or stay single-sig. So that's it: multisig isn't hard to understand, it's hard to execute. More moving parts mean more ways your backup fails when you need it.

I deeply empathize with all affected Cold Card plebs. My thoughts are with you all during this difficult time. It's tearing my own heart apart too. Stay strong. Onwards. 🫡

"Because here is what the strategy of tension actually wants: it wants us tribal. It wants the community exhausting itself in a two-sided war while the real campaign — stablecoins, CBDCs, custody, hashrate, developers, economic nodes, all centralizing at once — proceeds above the noise. The most radical thing we can do is refuse the tribalism, understand the whole board, and resist concentration wherever it appears, on either side." -- Simon Dixon https://www.simondixon.com/blog/bip-110-the-spam-war-and-the-battle-nobody-wants-to-name-where-i-stand-simon-dixon #bip110

Thank you for the hint about private zaps to exchange information.

yes. or dm's fixed in nostr. PV 🫂
