[feat] Optimize the way we serialize transactions

[maciejka]

Currently we use Encode trait to serialize data before hashing. There is a performance problem in this approach as ByteArray, which is a type of the buffer we serialize to, is not the type sha256 works with. So ByteArray needs to be converted to Array<u32> before hashing. It would be more optimal to use Array<u32> as a buffer type in the codec module.

Hi @maciejka
Please can I work on this?

Hi @maciejka Please can I work on this?

HMMMM

@maciejka let work and optimize this part of the code,

here is how i will approach,

• Change Buffer Type: Update the codec module to use Array as the default buffer type for the Encode trait instead of ByteArray. -Update Encoding Logic: Adjust the encoding logic to serialize data directly into Array. This may involve modifying the Encode trait implementation to work natively with Array.

• Test and Benchmark: After implementing the change, thoroughly test the encoding and hashing process to ensure data integrity and then benchmark it to verify the performance improvement.

Hey @maciejka Can I take this up, as I have worked with encode trait before

[Jeanmichel7]

Interested too. Exercise I've already done and am familiar with Encode
