Transactions – I incorrectly sent my Bitcoin to a blocked address. How can I get my Bitcoin back?

If you send bitcoins to an address for which you do not have the private key, you can no longer control this bitcoin. It is owned (or lost) by another person at this time.

If you know the owner of the address, you can ask please send them to you, but this will obviously not help if they are criminals. If you've been cheated (tricked into sending Fraudulent Bitcoin to someone), you can report it to a website like this (to help others) and / or the police.

Note: as mentioned by Pieter – there is no "blocked address" in Bitcoin. Any address with the correct format is valid.

What happens if the power fails during the bitcoin mining process and the system turns off?

Although your Bitcoin is completely secure with decentralized storage of the blockchain, the real risk is that the private keys in your wallet will be lost due to damage to the hard drive or a failure during a power failure.

Once private keys are gone, they're gone forever.

It is advisable to make a backup copy of your wallet or private keys that you can keep safe if your hard drive is lost for any reason.

Just look at the wallet help – Bitcoin Stack Exchange

I only send this to a wallet. But that was wrong. What I can do to send it to the right wallet.

Bitcoin transactions are irreversible. You cannot cancel or reclaim them. Therefore, you cannot now redirect these bitcoins into the correct wallet.

Clock-only addresses are only controlled by those who know the corresponding private key.

If you know who owns the clock-only address private key, you can ask them to make a new payment equal to the amount you sent them. You have to rely on your charity.

Transactions – Generate P2SH-P2WPKH – Bitcoin Stack Exchange

I want to replicate the same scenario bitcoin-cli getnewaddress "" "p2sh-segwit"To achieve my goal, I follow this guide

My wife is:

cPc4kNYhmuEym2VuskuLbhvPnJwXZGKcR6eRQL4Rv3KCJKUsatmQ

then my compressed public key is:

024aa21263ae0cb132cb0db16096bb4c9c475f53d476c8e83ec3a5586898a1a781

Generate my redemption script. Precede 00 (OP_0) and create a key hash (ripemd160 (sha256 (public key)).

00146672614baf71a8d9e06e11e22562e8f16fad60fa

ScriptPubKey is ripemd160 (sha256 (redeem script))

3f07def7d741bed449f76068422691c9cf2e2ec1

And create my address (rain test)

C43f07def7d741bed449f76068422691c9cf2e2ec1 | xxd -p -r | base58 -c

result:2MxzVzFg34B2i3Guub7y3kLAKgdoaYQfMCD

Now I want to issue some Bitcoin from this address. It has 50 bitcoins
Create my transaction details

TX_DATA=$(bitcoin-cli createrawtransaction '({"txid":"'$TXID'","vout":'$VOUT'})' '({"'$ADDR_DEST'":'$AMOUNT'})')

and then create signrawtransactionwithkey

REDEEMSCRIPT=00146672614baf71a8d9e06e11e22562e8f16fad60fa
SCRIPTPUBKEY=a9143f07def7d741bed449f76068422691c9cf2e2ec187
WITNESS_SCRIPT=6672614baf71a8d9e06e11e22562e8f16fad60fa (it's sha256 and ripemd160 of public key)

bitcoin-cli signrawtransactionwithkey $TX_DATA '("'$PK'")' '({"txid":"'$TXID'","vout":'$VOUT',"redeemScript":"'$REDEEMSCRIPT'","scriptPubKey":"'$SCRIPTPUBKEY'","witnessScript":"0014'$WITNESS_SCRIPT'","amount":"'$TOTAL_UTXO_AMOUNT'"})' 

I get this error:

{
  "hex": "0200000001ea237a61a6250e40a1461f1599e2a7b2c80e30ce6f3951ee0679d4d237ee431800000000171600146672614baf71a8d9e06e11e22562e8f16fad60faffffffff016036f8290100000017a914309a334914af79f24a5f10c9845d01e518c801488700000000",
  "complete": false,
  "errors": (
    {
      "txid": "1843ee37d2d47906ee51396fce300ec8b2a7e299151f46a1400e25a6617a23ea",
      "vout": 0,
      "witness": (
      ),
      "scriptSig": "1600146672614baf71a8d9e06e11e22562e8f16fad60fa",
      "sequence": 4294967295,
      "error": "Witness program hash mismatch"
    }
  )
}

I don't understand what the witness program is, and I don't know why I'm getting this error.
When i use bitcoin-cli getnewaddress "" "p2sh-segwit" and create transaction, I can see this:
asm contain the sha256 and ripemd160 of public key and the field txinwitness with signature and public key.

Thanks a lot
