Title: Assertion failed when submitting block with Satoshi's address

1. Open Bitcoin Core regtest.
2. Type in console:

Code:

submitblock 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

3. Some error message is displayed:

Code:

---------------------------

I wonder if it is possible to remotely crash nodes by feeding them with such blocks.

What version of core do you currently use?

The error seems related to Bitcoin file corruption.

Is it full sync? You can make a backup of bitcoin to another hard drive and uninstall the Bitcoin core then after that put the backup Bitcoin data back to the original location and install bitcoin core again(Make sure to download it again).

Let see if it can remove/fix the error.

Seems unlikely, given that the assert is happening in wallet code. It doesn't crash v0.21 client:

Code:

***@***~$ bitcoin-cli -datadir=*** -rpcconnect=*** submitblock 0100000006226e46111a0b59caaf126043eb5bbf28c34f3a5e332a1fc7b2b73cf188910f3ba3edfd7a7b12b27ac72c3e67768f617fc81bc3888a51323a9fb8aa4b1e5e4aed046061ffff7f20000000000101000000010000000000000000000000000000000000000000000000000000000000000000ffffffff4d04ffff001d0104455468652054696d65732030332f4a616e2f32303039204368616e63656c6c6f72206f6e206272696e6b206f66207365636f6e64206261696c6f757420666f722062616e6b73ffffffff0100f2052a01000000434104678afdb0fe5548271967f1a67130b7105cd6a828e03909a67962e0ea1f61deb649f6bc3f4cef38c4f35504e51ec112de5c384df7ba0b8d578a4c702b6bf11d5fac00000000

1. Open Bitcoin Core regtest.
2. Type in console:
-snip-

I've followed this exactly but I didn't encountered any error. Tested in both v0.21.0 and v22.0 - Windows10 OS.
Maybe it's an isolated case?

The latest official 22.0 release.

Quote

Is it full sync?

It is regtest, there are no connections, I just put the next block after Genesis by myself.

Code:

high-hash

In regtest it matches the minimal difficulty, in other networks it has to be mined first.

Try also importing Satoshi's public key:

Code:

importpubkey "04678afdb0fe5548271967f1a67130b7105cd6a828e03909a67962e0ea1f61deb649f6bc3f4cef38c4f35504e51ec112de5c384df7ba0b8d578a4c702b6bf11d5f" "satoshi"

I deleted all data files and executed both commands, then I reached the same error again. So maybe it works only if someone imported Satoshi's key.

Okay, now I got the assertion error if I import satoshi's pubkey before executing the command (using a fresh datadir).

However, node didn't crashed and there's no error in the debug.log, and it seems like the command worked at the first attempt regardless of the error.
So I doubt that it could be used to attack other nodes (or rather satoshi's node, bec. it requires his pubkey :P).
