bad_cb_height in regtest in every block

I'm having a problem trying to generate blocks for Regtest. I get always an error:

ERROR: AcceptBlock: bad-cb-height, block height mismatch in coinbase

The height of the block I'm trying to mine is 1. So the Coinbase transaction I'm using is:

02000000010000000000000000000000000000000000000000000000000000000000000000ffffffff3f01013c8cb3d83abd14588177040029eb9bf1bf952f1f43af61e6df03578d5e3bb261a8e2a4bb1bb2da4bc180d3fc67bd1c73aac0575e280239c2f30dc3acb0000000000100f2052a010000001976a914bf01aa10263be4a8f6cabbdd60a74c7544e48d2a88ac00000000

whose parts are:

02000000

01

0000000000000000000000000000000000000000000000000000000000000000

ffffffff

3f (<- This is the size of the scriptsig (63))

0101 (<- This is the height. Its value is 1 and it is using 1 byte)

3c8cb3d83abd14588177040029eb9bf1bf952f1f43af61e6df03578d5e3bb261a8e2a4bb1bb2da4bc180d3fc67bd1c73aac0575e280239c2f30dc3acb (<- And I add 60 (3c) random bytes)

000000000 (<- The sequence)

01 (<- One transaction which is the Coinbase)

00f2052a01000000 (<- The amount of Satoshis)

1976a914bf01aa10263be4a8f6cabbdd60a74c7544e48d2a88ac (The ScriptPubKey)

00000000 (The locktime)

I don't see what is the problem with the height value. Someone knows? Thanks

Future of Bitcoin encryption and security in a QC era

How will the advancement of quantum computing impact the security of Bitcoin, and what steps are necessary to protect the network from this emerging threat? What role could lattice-based encryption play in safeguarding Bitcoin, and which of the current algorithms are best suited for this purpose? How would the implementation of such encryption technology be integrated into the existing Bitcoin infrastructure, and what challenges might arise during this process? What happens to existing addresses that rely on elliptic curve cryptography? Is there a way to seamlessly transition old addresses to the new system, or would users need to actively transfer their funds to new, more secure addresses? How could such a transition be designed to ensure user security while maintaining trust in the network? from Recent Questions - Bitcoin Stack Exchange https://ift.tt/aZeY2fo via IFTTT

Possible rollback due to lazy reveal in BRC20?

Let's assume user A committed an inscription with {"op":"deploy", "tick": "test"} at block 100 (without revealing it yet). Then user B commits and reveals the exact same inscription at block 101. Because the indexer isn't aware that A's earlier commit was actually for "test," it recognizes B's "test" token as the official one. From blocks 101 to 199, users freely perform various "test" token transactions (e.g., "mint" , "transfer" ). However, at block 200, user A finally reveals their earlier commit. In that case, will the indexer roll back all "test"-related histories that happened between blocks 101 and 199? If so, can we really trust that all BRC20 tokens recognized by the indexer are "safely" the official ones? from Recent Questions - Bitcoin Stack Exchange https://ift.tt/CsYKVTa via IFTTT
