[FabioCarpi]

get the raw of block 0

Code:

f9beb4d9 - mainnet
1d010000 - lenght (varint)
01000000 - versao
0000000000000000000000000000000000000000000000000000000000000000 - hash

29ab5f49 - time
ffff001d - bits
1dac2b7c - nonce
01 - tx count
   01000000 - tx version
   01 - in count
      0000000000000000000000000000000000000000000000000000000000000000 - prev_hash
      ffffffff - vout
      4d - script count (77)

   00000000 - lock time 

have a easy way to get the raw of each tx?
i miss a byte like "tx lengh" after the tx count...
my dificult is because the script count maybe 1 or 2 bytes...

No need for tx length. Parse transactions starting afte rthe block header following https://en.bitcoin.it/wiki/Protocol_specification#tx

You have to parse the transaction.

the script length is a varint.  You got the parsing a wrong in the second script.

43 is the length of the script. The script is 4104678afdb0fe5548271967f1a67130b7105cd6a828e03909a67962e0ea1f61deb649f6bc3f4ce f38c4f35504e51ec112de5c384df7ba0b8d578a4c702b6bf11d5fac, the first opcode (0x41) pushes the next 0x41 bytes (public key), the second opcode is 0xac (OP_CHECKSIG)

block length is not varint
