Valid public key check in transaction output

Valid public key check in transaction output

Let's say I build a P2MS output script using uncompressed public keys, and let's say too that these public keys are not valid, i.e. they do not represent a valid EC Point and they don't start with 0x04. Will this transaction be broadcasted and included in a block or, among all the validity and standardness checks, a peer also controls that public keys are valid and rejects the transaction if they aren't ? Thank you very much !

Need help to recover blpckchain.info wallet, my wife forgot her password and the brute force with btcrecover is not catching the password

Need help to recover blpckchain.info wallet, my wife forgot her password and the brute force with btcrecover is not catching the password I used btcrecover to extract the wallet file (wallet.aes.json) from a blockchain account and I have been running btcrecover with dictionaries of my making but it has been going on for weeks and I am running out of ideas on how to permutate what my wife and I think the password could have been.

We do not have: The pri...

When downloading the blockchain my application is become unusable, is there an issue with my code or am I using the BitcoinJ library incorrectly?

When downloading the blockchain my application is become unusable, is there an issue with my code or am I using the BitcoinJ library incorrectly? I am building a Bitcoin wallet with the BitcoinJ Library, after looking at the example of fetching a transaction that they have shown on their github it shows that you need to download the blockchain however. When attempting to download the blockchain to view the balance of my wallet, it begins to lock up and become unusable. I have even tried downloading the blockchain in an async task like so, but still the app becomes completely unusable and the UI doesn't even load. What am I missing? I thought that the download wouldn't be that large as I am attempting to create an SPV wallet which from what I understand doesn't download the entire blockchain, or is this something I need to configure seperately? class MainActivity : AppCompatActivity() { override fun onCreate(savedInstanceState: Bundle?) { DownloadBlockchain(...
