The Developer’s Guide to Hedera Hashgraph
summary
Step-by-step demo of building on Hedera: register at portal.hedera.com testnet auto-funds 10,000 HBAR; create a Node.js project, npm install @hashgraph/sdk >=2 and dotenv; put account ID and private key in .env; call Client.forTestnet(), construct TokenCreateTransaction with name, symbol, decimals, initial supply (example: 1,000) and TokenCreateTransaction with treasury=operator, execute to get tokenId, then AccountBalanceQuery to verify holdings. Claims: native token service handles tens of thousands TPS, ~3s finality and supports atomic token swaps and Ethereum bridges; demo apps and a $3,000 hack challenge are available.
