What is the exact process for importing bitcoincore descriptor wallet to Sparrow Wallet

I recently converted a legacy wallet to a bitcoincore descriptor wallet. Now I'd like to create a new Sparrow wallet and import (not sweep!) the transaction history and balances to it. The Sparrow client is already configured to connect to a Raspiblitz full node over Tor. I'm finding difficulty specifically with how to import the descriptors fully and correctly (with included transaction history). I'm willing to entertain interim steps as long as the at the end I end up with a functional (non-watch) wallet in sparrow that is a duplicate of the bitcoincore wallet. from Recent Questions - Bitcoin Stack Exchange https://ift.tt/vLalSCd via IFTTT

Where are inner null bytes valid in p2p messages

P2P messages use null bytes as padding when the field size is larger than the content. For example, a command field is interpreted as 12 byte ASCII, so the version command is typically as follows: version\0\0\0\0\0 My question is, is it also valid to have inner null bytes? eg: ver\0sion\0\0\0\0 Some protocol applications I notice treat inner null bytes as valid, which seems mistaken. from Recent Questions - Bitcoin Stack Exchange https://ift.tt/oMqS6sa via IFTTT

bitcoin core quickest method legacy -> descriptor wallet migration

I had a power outage recently and realized my current setup needs to change. The old ass laptop that I use for just bitcoin core needs to be retired. I've been running a pruned node on it forever. it's been OS updated recently and the blockchain is catching up once again. I'm thinking to move to Sparrow wallet synced to a Raspiblitz instance (over tor) and the have a method for importing the bitcoin core wallet via output descriptors. However the few times I've tried to migrate the legacy wallet bitcoin core (v31 now) have complained about the process and demanded a blockchain re-index. ex: [error] Prune: last wallet synchronisation goes beyond pruned data. You need to -reindex (download the whole blockchain again in case of a pruned node) That's not really feasible even if I wanted to since this old machine is struggling even to catch up to the last week of being offline, nor do I even have the space on it anymore for a full blockchain. So the que...

What's the current situation with Bitcoin testnets?

What kind of wallet or protocol would sign a Taproot keypath spend with SIGHASH_NONE?

Browsing early Taproot transactions, I came across this one (block 709,911, ~280 blocks after Taproot activation): https://mempool.space/tx/ef72502f5d2509f519be33304e385bdf9d1bed5e4cd19f7a254700299db2ba91 What caught my eye: It's a P2TR keypath spend, single input, single output, dust-level amount (1943 → 1803 sats) The witness signature is 65 bytes ending in 0x02 — i.e., SIGHASH_NONE (not SIGHASH_NONE|ANYONECANPAY which is 0x82) nSequence is 0x9f (= 159), which under BIP68 would imply a relative timelock of 159 blocks Plain SIGHASH_NONE (without ANYONECANPAY) on a 1-input-1-output transaction seems strange to me — the signer is essentially saying "I authorize spending this UTXO regardless of where the output goes," but there's only one output. Anyone seeing this in mempool could in principle replace the output and rebroadcast. Questions: Is there a known wallet or protocol that signs P2TR keypath with plain SIGHASH_NONE (0x02)? I'd expect 0x82 (NONE|AN...
