(disclaimer: I'm not an expert on Lightning) I believe the design for Watchtowers (the services which watch for other parties trying to push an old state to the chain) is such that they're not actual …

After reading a lot of articles, whitepapers and videos I am still confused why do we need SegWit and Lightning instead of just bigger blocks. It's not a question of one or another. They are all …

A lot depends on how you define "scalable". If your question is: do we have ready-to-go technology, which without further on-chain Bitcoin protocol changes, is sufficient for making everyone on the pl …

Bitcoin Script has only one function: determining the conditions under which a transaction output can be spent, in its entirety. The result of evaluating a script is just "true" or "false". So no, you …

As far as I know, the malleability issue was fixed with the Segwit soft fork in August 2017. Yes. Was the malleability issue fixed with SIGHASH_NOINPUTor with some other method? No, using S …

That doesn't make sense. You can't send on-chain BTC to a Lightning invoice, as the former requires an on-chain transaction to move funds, while the latter is the updating of balances in a channel. Th …

I think this question is based on a false premise. The lightning network is not a platform for building novel smart contracts. It is a payment network built on top of the smart contract functionality …

Think of the blockchain as a court of law. A perfectly fair and incorruptible court which - if presented with a dispute - always rules justly. However, like real-world courts, it has high operational …

I don't know what the design decisions were that led to this, or their rationale, but: Particularly if you run a MAINNET node and a TESTNET node on the same machine, how would the host know which inc …

Will Taproot allow me to skip Lightning Network and simply use pure Bitcoin Core? Well, Bitcoin Core doesn't support Lightning for now, and probably won't for the foreseeable future, but there is no …

How can I run a Bitcoin SPV node? You run Bitcoin SPV software. They're often called "lightweight clients" or "lightweight wallets". Several mobile wallets implement SPV validation, as does Electrum …

Bitcoin Core 22.0 only supports 64-bit x86 platforms. The Atom N270 is a 32-bit CPU, so it is not supported. It may be possible to compile the 22.0 source code yourself for a 32-bit platform however, …

The following address uses witness version 0 Correct. and its checksum is the one expected for bech32m addresses. No, it uses the bech32 checksum. What makes you conclude that it is bech32m? Howe …
