Separate Witness: Deep Diving to Ethereum Events
As we study the complexities of the block structure of Ethereum, one concept stands out as particularly fascinating: a separate witness (SW). In this article, we look at what the SW event looks like and how it works on the Ethereum network.
Current transaction structure
A typical Ethereum event consists of several components:
- Version : A syllable group that defines the type of event (eg 0x01 for a normal event).
- Inputcount : An integer that indicates the number of inlet parameters.
- [TXID] : The ID of the previous block.
- …
Separate structure of witness trade
The SW event is similar to the regular Ethereum event but has a central difference:
- Instead of storing the entire input data in one syllable group, each inlet parameter is recorded separately.
- Each inlet parameter is a prefix on the
0x01(Segwit prefix).
- The event also includes additional metadata, such as the sender and the recipient’s public keys.
Here’s an example of a SW event:
`
Version 0x01 | [txid] …
^ ^ ^
And 0x1a | [Inputparam1]
And 0x1e | [Inputparam2]
Version 0x02 | [txid] …
^ ^ ^
And 0x19 | [Inputparam3]
`
As you can see, each inlet parameter is a prefix with the 0x01 segwit prefix and then the corresponding public key. This allows for more efficient storage of feed data and reduces the risk of key collisions.
How a separate witness acts
When the user sends a SW event to the Ethereum network, the network nodes will check it with the following steps:
- Event structure : The sender's public key and the public key of the recipient are removed from the store.
2
- Prefix Removal :0x01` Segwit prefix is deleted, revealing raw income information.
- Verification : The resulting supply data is verified by network nodes using Merkle or other hash-based certification mechanisms.
Benefits of the Separated Witness
A separate witness offers several benefits:
* Effective storage
: Each inlet parameter can be stored independently, reducing memory use and improving scalability.
* Improved safety : Decreased key collisions and increased supply information random make SW safer.
* Improved performance : Faster event processing times are achieved due to decreased overhead revision checking.
In summary, a separate witness is a strong concept that improves the efficiency, safety and performance of Ethereum commercial activities. By understanding SW, we can better appreciate the complexity of the Ethereum network and explore its potential to improve the user experience.
