The practical viability and utility of blockchain networks are important topics to think about.
The benefits and effects of leveraging a fully sharded architecture go far beyond performance enhancements.

Proper reset of warm instances: finalization and tests. We have been experimenting with them for a while for read-only SC queries and now they are ready for full use. Warm instances will bring the biggest SC execution optimization.
The NFT service now supports interpreting marshalized NFTs in smart contract results. Worked on indexing bulk buy on auctions and added sorting by likes, follows, and stats for the explore page, among other improvements & bugfixes.
Multi-Factor Authentication: added user signature verification, new API route and service specifications for account guardian. Fetcher for guardian info from protocol.
