Built on OpenEthereum

The World Food Programme and OpenEthereum

In 2016, the UN World Food Programme launched Building Blocks, which uses OpenEthereum to make the transfer of cash assistance faster, cheaper and more secure.

High Performance

Finely tuned & optimised use of the fast Rust language EVM turbocharges execution of complex contracts Multi-level in-memory caching.

Easy to use

1-line installers for Mac and Linux with fully documented Library APIs.

Ultra Reliable

Memory and concurrency safety guaranteed by Rust language actor-based modularity ensures maximal resilience.

Small Footprint

Rust's ownership tracking facilitates minimal memory footprint cache management gives fine control to user state-trie pruning minimises storage footprint.
