Ethereum’s understanding of two bag features: op_hashashashashasha256
Ethereum Blockchain uses two bag features, each with its strengths and weaknesses to protect and inspect operations. In this article, we will divide the differences between the op_hashashashashashaashaashaashashashashashas256, explaining the consumption over you and the Woods.
What are the functions of the bag?
In the context of the bag function in the context of Ethereum, Abu Op_hashash160 and OP_SH256 are used for notification and data integrity.
OPHASH160:
* Version: Delivered BIP 0012
* Description: bag function based on Sha-2
* Basic properties:
+ Uses 20 bytes input block (128 bits)
+ Signed with a private key using ECDSA (Elipse curve digital signature algorithm)
+ More resistant to collisions and transfer attacks due to its length
* Why op_hash160?

- easier to implement: Because OPHASH160 users Sha-256, it is accepted and too much, implementing the op_hashashashashashhashashashhashashash.
- better resistance to collisions:
op_sha256:
* Version: Delivered BIP 0013
* Description: Magna Function Sha-256 (the same as ECDSA)
* Basic properties:
+ Uses a variable length input block in UPS
+ Signed with a private key using ECDSA
+ Less resistant to collisions and hostages to attacks due to its dynamic length
* Why op_sha256?*

Example Scripts unlock:
“Gere” are some examples of BIP 199 scenarios that come to the OPHASHASH160 and OP_SH256 to authenticate the message:
OPHASH160:
`c
Contract from unlocking (
BOS32 _INPUT,
Eddress _privatekey,
BYS _signature
) {{{
// Check Signature Use ECDSA (ECDSA Used by BYD)
Require Ecdsaverify (_signature, _privatekey, _input);
}
Function _ecdsaverify (ITES Memory _Signature, DDDRESS _PRIVATEKEY, BYS32 _INPUT)
// … (ECDSA Confirmation Logic)
// Check the input Use Sha-2
Require Sha256 (_input) .equals (_sigganta);
}
`
OP_SHA256:
`c
Contract from unlocking (
BOS32 _INPUT,
Eddress _privatekey,
BYS _signature
) {{{
// Check Signature Use ECDSA (ECDSA Used by BYD)
Require Ecdsaverify (_signature, _privatekey, _input);
// Check the input Use Sha-2
Require Sha256 (_input) .equals (_sigganta);
}
