This is Michiel from Hashgraph, bringing you the January developer highlights.
We're exicted to announce the introduction of the Hedera Developer Playground. This browser-based tool enables developers to write, execute, and share code snippets and flows directly in their web browser, utilizing the Hedera testnet.
This edition offers two great video tutorials by Jake showing you how to deploy an ERC-20 token and how to use Chainlink's data feeds. Check out the different resources and make sure to take a look at our very own conference called HederaCon!
Learn how to deploy an ERC-20 token on Hedera using MetaMask, Remix IDE, and OpenZeppelin's Contract Wizard. Perfect for beginners! Set up your Hedera account, import your ECDSA key into MetaMask, and configure Hedera's JSON RPC.
In this workshop video, Jake Hall explains how to leverage Chainlink Data Feed Oracles in your Hedera Smart Contracts. In this we build a Smart Contract which enables the sale of an NFT for a fixed dollar price, in a dynamic amount of HBAR or BTC.
By leveraging Hedera's architecture, Sirio integrates TWAP (Time-Weighted Average Price) calculations and HBAR/USD conversions, ensuring secure, resilient price feeds. This oracle-free method not only enabled seamless development but now enhances the protocol's security as a backup to traditional oracles.
Hedera is simplifying blockchain data consumption with a unified format that merges event, record, and sidecar streams. This innovation enhances verifiability, streamlines integration, and introduces features like state proofs and interledger communication.
This HIP updates the rules for charging fees for EthereumTransactions, so that the payer of an EthereumTransaction will only incur a fee if the transaction fails due diligence checks.
This HIP proposes an expansion to the approval and allowance network logic (i.e. CryptoApproveAllowance, NftAllowance and TokenAllowance) by allowing any account on the network to provide allowances that will sponsor the payment of the fees for another account’s submitted transactions.
Hedera currently supports two cryptographic algorithms: ECDSA (secp256k1) and Ed25519. This HIP recommends adding support for a post-quantum cryptographic algorithm, to ensure resilience against quantum computer attacks.
This HIP introduces and proposes the adoption of a new node type that is designed to parse the block stream, store latest state and serve up additional network APIs such as state proofs and block retrieval that support decentralized querying and verification of state.
