How automatically resolved Ethereum Blockchain’s “Hard Double Furty”
In January 2015, the Ethereum network was significantly modified by introducing a new background database management system. BDB Change (binary database) from Bitcoin to Leveldb in 0.8 marked an important point of turn of the Ethereum project. Although these changes were designed to improve performance and scalability, this also raised concerns between miners and users.
“Hard Hard”
On February 28, 2015, the Ethereum team developer group decided to have automatic heavy network bifurcation. These changes avoided the need for a traditional merger or consensus protocol, allowing the new database management system to take responsibility without interrupting the existing block circuit.
As part of this process, several major changes were made:
- ** Changed databases.
- Increase in Lock Size Limit : A greater block size limit was introduced, allowing larger transactions and more sophisticated data structures.
3
Mainnet and TestNet Fusion : The Ethereum team decided.
resolution mechanism
The automatic hard fork mechanism said that no unit or group had only control over the network integrity. Instead, it was based on a decentralized solution:
1
Automatic update : Ethereum equipment used a script -based process to automatically update the block circuit.
- Node coordination : Each node in the network was responsible for checking and execution of the changes.
3
The Ministry of Consensus
: Although not clearly mentioned, some kind of unanimity mechanism (eg work test or tolerance against Byzantine failures) may confirm updates.
Benefits and Challenges
Automatic solid bifurcation solved several problems:
1
Improved scalability : Increased block size limit allowed more sophisticated data structures and larger transactions by improving network performance.
- Improved Security : A new database management system reduced the risk of corruption or data manipulation.
However, this process also introduced challenges:
1
Interruption of the operating basin of the mining pool : Changes in the rear databases affected the ability of some miners to confirm the transactions that led to possible interruptions in their actions.
- Network instability : Although most knots were updated and coordinated, there was a short period (about 24 hours) when some nodes had difficulty integrating with the new database.
Conclusion
The use of an automatic hard fork mechanism Ethereum community community marked an important step for the blockchain project during the BDB transition to Leveldb. While this process introduced the challenges, he confirmed that the network was protected and maintained without the need for a traditional consensus protocol or centralized control.
