aptos-core

Aptos-core is the official repository for the Aptos blockchain, a Layer 1 blockchain designed for safe and scalable real-world Web3 applications. It focuses on high throughput, low latency, and strong security measures, utilizing the Move programming language for smart contracts.

Pros

• High performance and scalability, capable of handling over 160,000 transactions per second
• Strong focus on security, leveraging the Move language's safety features
• Active development and regular updates from a dedicated team
• Comprehensive documentation and developer resources

Cons

• Relatively new blockchain, still building its ecosystem and user base
• Limited track record compared to more established blockchains
• Learning curve for developers unfamiliar with the Move language
• Potential for centralization concerns due to its validator structure

Code Examples

1. Creating a simple Move module:

module 0x1::basic_coin {
    struct Coin has key {
        value: u64,
    }

    public fun mint(account: &signer, value: u64) {
        move_to(account, Coin { value })
    }

    public fun balance(account: address): u64 acquires Coin {
        borrow_global<Coin>(account).value
    }
}

2. Interacting with the Aptos blockchain using the TypeScript SDK:

import { AptosClient, AptosAccount, FaucetClient, TokenClient } from "aptos";

const client = new AptosClient("https://fullnode.devnet.aptoslabs.com/v1");
const faucetClient = new FaucetClient("https://faucet.devnet.aptoslabs.com", client);

const account = new AptosAccount();
await faucetClient.fundAccount(account.address(), 100_000_000);

const tokenClient = new TokenClient(client);
const collectionName = "MyCollection";
const tokenName = "MyToken";

await tokenClient.createCollection(
  account,
  collectionName,
  "My first collection",
  "https://example.com/collection"
);

await tokenClient.createToken(
  account,
  collectionName,
  tokenName,
  "My first token",
  1,
  "https://example.com/token"
);

3. Querying the Aptos blockchain using the REST API:

import requests

NODE_URL = "https://fullnode.devnet.aptoslabs.com/v1"
account_address = "0x1"

response = requests.get(f"{NODE_URL}/accounts/{account_address}")
print(response.json())

# Get transactions for the account
txn_response = requests.get(f"{NODE_URL}/accounts/{account_address}/transactions")
print(txn_response.json())

Getting Started

To start developing on Aptos:

1. Install the Aptos CLI:

   curl -fsSL "https://aptos.dev/scripts/install_cli.py" | python3
   

2. Set up a local development environment:

   aptos init
   

3. Create a new Move project:

   aptos move init --name my_first_project
   

4. Compile and test your Move modules:

   aptos move compile
   aptos move test
   

5. Deploy your module to the Aptos devnet:

   aptos move publish --named-addresses my_addr=default
   

For more detailed instructions and advanced usage, refer to the official Aptos documentation.
