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

Bitcoin Mining Could Be Strengthening The Ruble, Russian Central Bank Says

Image
Bitcoin mining may be providing incremental support to the Russian ruble, Central Bank Governor Elvira Nabiullina said, while cautioning that the effect is difficult to measure because much of the sector still operates in a legal and reporting gray zone. Bitcoin Mining May Support The Ruble Responding to a question at a press conference, Nabiullina said it is “probably difficult to quantify” mining’s influence “because a significant part of mining is still in a gray area.” Still, she added that mining is “indeed one of the additional factors contributing to the strong ruble exchange rate.” As Russian business news portal for RBC reported , her remarks come as Russian officials increasingly frame mining and crypto flows as macro-relevant, not just a niche tech or energy story. Earlier, Maxim Oreshkin, deputy head of the presidential administration, said ruble forecasts have been thrown off by the underestimation of financial flows tied to mining and cryptocurrency. In his view, the s...

Crypto Exec Warns Tokenization Is Moving Faster Than Expected

Image
According to a post shared on X by Keith Grossman, president of crypto payments firm MoonPay, finance is heading toward an onchain future that could unfold over several years. The view comes as large banks and asset managers begin product tokenization, a move that once seemed extreme but is now being treated as a practical step by major institutions. Regulatory Signals Push Institutions Forward Based on reports cited by Grossman, progress has accelerated because rules are becoming clearer. Legislative efforts, regulatory guidance, bank involvement and accounting standards are starting to line up. That combination reduces uncertainty, which is often what slows large pools of capital. BlackRock has already launched tokenized funds, while Franklin Templeton is running tokenized money market funds on public blockchains. Those actions suggest that tokenization is no longer confined to pilot labs or internal trials. It is being used with real assets and real clients. Bank of Ameri...

Bitwise Clients Pour $69M Into Solana as Bulls Fight to Reclaim $200 Resistance Zone

Institutional confidence in Solana (SOL) continues to surge as Bitwise clients invest a massive $69.5 million, supporting the blockchain as a frontrunner among alternative Layer-1 assets.
