Can you actually leave? We tested it on mainnet: forced a 100k sat Blink wallet out of Spark, back onto Bitcoin. No operators, just the seed and a saved recovery bundle. Costs, lessons, code and txIDs onchain:

Case study: a real Spark unilateral exit on Bitcoin mainnet

Recovering 100k sats with seed and state backups.

Trust model reiterated. In-app exit next.

Correction: "seed only, no operators" compressed two steps. The leaf data (recovery bundle) must be fetched while operators are online. The exit itself then needs nothing from them: seed + saved bundle is the accurate claim. Full mechanics and costs:

I just force-exited a non-custodial Blink wallet (using Spark) on Bitcoin mainnet. Seed only - no operator cooperation: recovery bundle, fee funding, CPFP signing and sweep all derived from the wallet seed. The honest numbers for a 100k sat wallet: • 22 leaves, 253 tx packages to exit fully • only 4 leaves (90% of the value) were worth exiting - fees would have eaten the other18 • ~9.4k sats in fees to recover 90.1k, one package per block per chain, then a ~2-week timelock Non-custodial means you can always leave. But the fire escape is narrow - full case study with costs, failures and lessons:

Syncing signet on an RPi5 should take less than an hour (but allow a little more time just in case). You can start the signet bitcoind instance on a Raspiblitz by running: config.scripts/bitcoin.install.sh on signet You will have these aliases set in terminal for easy monitoring and configuration: alias sbitcoin-cli="sudo -u bitcoin /usr/local/bin/bitcoin-cli -rpcport=38332" alias sbitcoinlog="sudo -u bitcoin tail -n 30 -f /mnt/hdd/app-data/bitcoin/signet/debug.log" alias bitcoinconf="sudo nano /mnt/hdd/app-data/bitcoin/bitcoin.conf" The systemd service is called: sbitcoind so can check and restart with: systemctl status sbitcoind sudo systemctl restart sbitcoind #raspiblitz #signet #bitcoin

is interesting, but if not using it in the Tor Browser, it must be connected to your own node. Can do both on a Raspiblitz already:

Nothing more motivating to hold your own keys than a hard fork lined up.

Increasing the OP_RETURN limit to match what can already be included in a valid block is like placing a garbage bin to a littered street. Can't stop people from littering and can't even make them to put rubbish in the bin, but can at least provide them with a less bad path. OP_RETURN outputs are paying a full price, not stored in the chainstate and are prunable from the downloaded data.
