Development Artifact Cleanup: ✅ BROTHER_NODE REORGANIZATION: Moved development test node to appropriate location - dev/test-nodes/brother_node/: Moved from root directory for better organization - Contains development configuration, test logs, and test chain data - No impact on production systems - purely development/testing artifact ✅ DEVELOPMENT ARTIFACTS IDENTIFIED: - Chain ID: aitbc-brother-chain (test/development chain) - Ports: 8010 (P2P) and 8011 (RPC) - different from production - Environment: .env file with test configuration - Logs: rpc.log and node.log from development testing session (March 15, 2026) ✅ ROOT DIRECTORY CLEANUP: Removed development clutter from production directory - brother_node/ moved to dev/test-nodes/brother_node/ - Root directory now contains only production-ready components - Development artifacts properly organized in dev/ subdirectory DIRECTORY STRUCTURE IMPROVEMENT: 📁 dev/test-nodes/: Development and testing node configurations 🏗️ Root Directory: Clean production structure with only essential components 🧪 Development Isolation: Test environments separated from production BENEFITS: ✅ Clean Production Directory: No development artifacts in root ✅ Better Organization: Development nodes grouped in dev/ subdirectory ✅ Clear Separation: Production vs development environments clearly distinguished ✅ Maintainability: Easier to identify and manage development components RESULT: Successfully moved brother_node development artifact to dev/test-nodes/ subdirectory, cleaning up the root directory while preserving development testing environment for future use.

/**
|
|
* Computes the [[link-eip-191]] personal-sign message digest to sign.
|
|
*
|
|
* This prefixes the message with [[MessagePrefix]] and the decimal length
|
|
* of %%message%% and computes the [[keccak256]] digest.
|
|
*
|
|
* If %%message%% is a string, it is converted to its UTF-8 bytes
|
|
* first. To compute the digest of a [[DataHexString]], it must be converted
|
|
* to [bytes](getBytes).
|
|
*
|
|
* @example:
|
|
* hashMessage("Hello World")
|
|
* //_result:
|
|
*
|
|
* // Hashes the SIX (6) string characters, i.e.
|
|
* // [ "0", "x", "4", "2", "4", "3" ]
|
|
* hashMessage("0x4243")
|
|
* //_result:
|
|
*
|
|
* // Hashes the TWO (2) bytes [ 0x42, 0x43 ]...
|
|
* hashMessage(getBytes("0x4243"))
|
|
* //_result:
|
|
*
|
|
* // ...which is equal to using data
|
|
* hashMessage(new Uint8Array([ 0x42, 0x43 ]))
