with multisig wallet on sparrow, is there a way to keep wallet balance/wallet-config private from collaborating signers

I've been trying to find a way to keep my bitcoin in a multisig wallet, currently on sparrow and have trusted family members in distant locations perform signing of various keys for me. I've been using a blockstream jade signer and 21x21 qr codes of a seed phrase. I can save a file to disc of my psbt, and securely send that file to my collaborator to sign. It works fine if I provide the entire wallet descriptor file and my signer duplicates my entire sparrow multisig wallet, but when I do that they see all the transactions and the bitcoin balance. Nunchuk finney wallet has something they call "blind co-signer" described at https://nunchuk.io/blog/finney which is pretty much what I am looking for. Except Sparrow seems to be better supported and more widely used than nunchuk. I asked Google "how to keep xpub and path information private from collaborating signers of my multisig wallet" and received some information that sounded hopeful but a...

What are the core architectural differences between a crypto trading bot and a custom-built one?

I've been researching automated crypto trading bot development and trying to understand the technical trade-offs between white-label solutions and custom-built bots from scratch. From what I've read so far, white-label bots come pre-built with: Multi-exchange API connectivity (Binance, Bybit, OKX, KuCoin, Kraken etc.) Pre-configured strategies like grid trading, DCA, and scalping Built-in backtesting engines AML/KYC compliance layers Risk management modules (stop-loss, smart order routing) Whereas custom bots built from scratch typically use stacks like: Python for ML/quant strategies Go or C++ for low-latency execution engines Node.js for real-time WebSocket handling TimescaleDB or InfluxDB for time-series price data Apache Kafka for high-throughput event streaming I came across this detailed breakdown on crypto trading bot development which covers the architecture, bot types, AI/ML integration, and cost tiers, but I still have some specific technical questio...

Why is bitcoin connected to the banks?

Bitcoin is decentralized. Banks are centralized. The powers that be were not supposed to let the banks attach to bitcoin. Short selling is not bitcoin, that is a stock. Please help free bitcoin. from Recent Questions - Bitcoin Stack Exchange https://ift.tt/8cIpiCd via IFTTT

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
