Create a simple local chain
You want to understand how blocks link together. You start by writing a small Python script that stores data in a local list. You add a hash function to verify each block. You run the script to see the chain grow. You check the output to confirm the links are valid. You save the file in your project folder. You use a contract oriented block explorer to inspect the deployed state.
Create file
Create a new Python script file.
Write code
Write the block structure and hash logic.
Run script
Run the script to verify the chain.
Design note for your chain
Create a Python script that defines a block class with index, timestamp, data, previous hash, and hash fields, and a function to validate the chain.

# Toy Chain Design
index: block number
timestamp: creation time
data: payload
previous_hash: sha256 of prev
hash: sha256 of this
nonce: proof number
rule: previous_hash must match prev block hash. No keys.This text file defines the fields for your toy chain. It lists the index, timestamp, data, previous hash, hash, and nonce. It includes a rule for validation.
How to build a blockchain app with AI
Map your repo
You start by understanding your current codebase and use list_dir to see all files in your working folder, so you can plan where to add your new chain logic. Check the list. The agent uses glob to find specific script files and grep to search for existing hash functions. You review the file structure to confirm the layout before proceeding. You decide to create a new module for the block class. You build a blockchain with clear logic and verified tests. The agent creates the new file in your directory for hybrid consensus blockchain pow plus voting. Approval modes like Ask first ensure you control every action that changes something in your repository.
Write and test
You write the block class with all required fields, and the agent uses write_file to create the new module so you can proceed with the hash calculation logic. You read the output. The agent uses Shell to execute your test script and you see the exit code clearly. You fix any failures reported by the suite and commit the changes. This approach helps you build a blockchain with a clear structure. You can also build a blockchain app that tracks data securely. Many wonder if blockchain is obsolete when considering simple local ledgers. The agent maps the repository using list_dir and grep to find where the contract function is used.
