create new block possible with genesis :
python genesis.py -z "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks" -n 2083236893 -t 1231006505

Why algo for next Block ??
And Can we find a block 2 months ago
11  Bitcoin / Bitcoin Technical Support / Re: Bitcoin block creation !!?? on: February 04, 2019, 03:38:52 PM
but what is the actual calculation used?
sha256 (number of transactions + nonce + prev bloc)..............................?

It's:
SHA256( SHA256( Version + hashPrevBlock + hashMerkleRoot + Time + Target + Nonce ) )

With the Merkle Root being the set of all transactions reduced to a single a hash:

The Bitcoin wiki has a good description of what is contained in the block header:

okok thank you

sha256(sha256(000000000000000000141653129dd4eb836978acc3c60e10e13ae53788aff716))       

result = next block  Roll Eyes

Hello someone would know how a bitcoin block is made it is

I know you have to take all the transactions but I don't know what to do with them afterwards.

and can we create a block with the desired number of transactions?

thank you to you
