ENNFT Claiming Contract Audit Completed

In a recent blog post from Runtime Verification they announced that the audit on the Earth Node NFT Claiming Contract has been completed. Runtime Verification is a software company founded in 2010 that specializes in formal verification, runtime monitoring, and security for complex systems. The company was started by a group of researchers and engineers from the University of Illinois at Urbana-Champaign, and it has since grown to become a leading provider of software verification tools and services.

Runtime Verification conducted a manual code review for a period of 3 weeks and delivered a detailed report on December 29th, 2022.

To ensure the correctness and security of the Earthnode NFT Contract, World Mobile engaged Runtime Verification to perform a thorough audit of the code. The audit process included manual code review, automated testing, and formal verification techniques which found a number of minor issues that were promptly addressed by the World Mobile development team.

The audit identified and highlighted some issues along with some informative findings. Runtime Verification conducted a best-effort review of code fixes and worked with the World Mobile Group team to incorporate code fixes into the smart contract.

Overall, the audit confirmed the correctness and security of the ENNFT Contract and gave World Mobile confidence in its ability to provide a reliable and secure mobile network infrastructure. Readers interested in a more detailed and technical explanation of the findings can review the full report in Runtime Verification’s GitHub repository.


Earth Node NFTs and Testnet launched

The World Mobile community have had a great start to 2023 with the launch of Earth Node NFTs (ENNFT) and the World Mobile Testnet, codenamed “Aya”. The name Aya comes from the Adinkra symbol, and it means fern. This symbol represents resourcefulness and endurance. Aya is built using the Cosmos SDK, interfacing with Cardano using smart contracts. Testnet is currently limited to a handful of Earth Node Operators (ENO’s) so the setup script and installation details can be streamlined and any issues ironed out.

The EarthNode NFTs (ENNFTs) are unique non-fungible tokens for EarthNode Operators which represent their ownership of an EarthNode. They are deployed on the Cardano blockchain, and each NFT has a unique number signifying the EarthNode it represents. EarthNodes are the heartbeat of the World Mobile network. Their operators earn rewards for processing transactions on the blockchain and securing the network, as well as offering value-added services.

All 1,000 available EarthNodes were previously reserved through a multi-stage process that culminated in a month-long auction for the last remaining nodes.

Those who have reserved an EarthNode are now able to claim their unique ENNFTs from within the WMT Vault and will need to do so to continue to participate in the EarthNode Operator Rewards Distribution Programme.

PSA: Please be careful when purchasing an ENNFT on secondary NFT marketplaces such as Be sure to check that the policy ID matches the official ENNFT policy ID here.
