hash160 VS sha256 ?

[directoryio]

Number of hash160 = 1461501637330902918203684832716283019655932542976
Number of sha256 = 115792089237316195423570985008687907853269984665640564039457584007913129639936

I do not understand why there is more hash in 256 than in 160.

thanks for responses and sorry for my bad english  .

RipeMD160 is more efficient when doing transactions, however, Sha256 will provide the security that MD160 can't. Both are used on BlockChains and both are useful to make it work properly.

Sha256 is more complex, consequently, more secure, but at the same time requires more characters in it's encryption method. MD160 efficiency comes from this, less characters, shorter address, but less secure.

The first one is a 160 bit hash.  That means that the hashing formula creates a 160 bit digest of the input data.  Since a "bit" is a binary digit (can have one of two possible values), the total number of possible values that can result is 2¹⁶⁰.

2¹⁶⁰ means to multiply 2 times itself 160 times.


The second one is a 256 bit hash.  That means that the hashing formula creates a 256 bit digest of the input data. Since a "bit" is a binary digit (can have one of two possible values), the total number of possible values that can result is 2²⁵⁶.

2²⁵⁶ means to multiply 2 times itself 256 times.

clear explanation. thank you for this

Possible to reduce hash ?

Sha256====>ripemd160====>md5

Yes.  But if you want md5, then just use md5.  Why waste time with SHA256 and RIPEMD160 first?
