Blockchain constitutes a deep cultural shift whereby ownership, transparency, and immutability become universal properties, gradually imbued in all systems.
Elrond has been designed from scratch to fill all the prerequisites of this transition.

We are closing in on a mainnet release candidate, with the recent discovery and fixing of several issues in the trie/state area that were preventing state snapshots when trie pruning was disabled.
Work in progress for a create-erd-app package that allows developers to bootstrap a working template of a dApp with a single command and as few prerequisites as possible.
Implemented public key encryption API for erdjs using x25519 with ephemeral static diffie hellman in order to allow developers to encrypt and store data in a contract (or anywhere else) and set a pre-specified address that can decrypt and read that data.
