BlockSec’s Collaborative Testing Tool: The Key To Flawless Private Chains

Key Points:

• BlockSec launches Phalcon Fork toolkit for collaborative testing on Ethereum mainnet.
• Provides greater control over transaction testing, analysis, and debugging.
• Features include snapshots and Fork RPC node for direct interaction with chains.

Blockchain security tech firm BlockSec has launched a new toolkit that enables collaborative testing on private chains “forked from arbitrary (transaction) positions” and block numbers on the Ethereum mainnet.

The toolkit called the “Phalcon Fork”, was launched on April 14th and is aimed at developers and security researchers.

The Phalcon Fork is designed to provide developers with greater control over the work being conducted on test nets such as transaction testing, analysis and debugging. With this toolkit, developers can easily “fork arbitrary (transaction) positions and block numbers” and retain certain “services and states” from the Ethereum mainnet, providing extra control and facilitating rapid integration and debugging with other DeFi contracts.

Compared with traditional solutions like Goerli, Phalcon Fork has several advantages. It allows users to retain services and states from the mainnet, maintain full control over block information (e.g., Timestamp, BaseFee, MixDigest), and enables them to utilize features such as snapshots, which can save certain blockchain positions, and revert back to them at will during testing. The snapshots essentially record the transactions being executed and deployed by the user at a given time.

The snapshot feature is particularly useful in the following two scenarios: when a user wants to run multiple times of a testing script, he/she needs to revert to the original snapshot and rerun the script. Additionally, when a user wants to save some states and return to them later, he/she can create a snapshot and then revert to this snapshot later.

Phalcon Fork also comes with an integrated faucet so that users can acquire free fork network Ether (ETH) to conduct transactions on the private chains. To directly interact with the chains and execute transactions, Phalcon Fork provides a Remote Procedure Call (RPC) node called Fork RPC, which can be integrated with Ethereum Virtual Machine compatible development frameworks such as Hardhat, Foundry and Remix, or added to MetaMask.

As of now, users can only fork from the Ethereum mainnet, however future support for additional blockchains such as the Binance Smart Chain and Arbitrum has been teased.

April has been a significant month for Ethereum developers, given that the highly anticipated Shapella hard fork went live on the Ethereum mainnet without a hitch on April 12th. A major feature of the upgrade enables Ethereum validators to withdraw staked ETH from the Beacon Chain.
