Bringing a new financial system: open, transparent, scalable & accessible to anyone, anywhere.

Get ready for DeFi 2.0

Weekly #elrondtech 🛠️

1/ The Elrond protocol has been tested & updated in preparation for the June mainnet upgrade release candidate, which will introduce important features leading up to Staking v4, an updated Rosetta API implementation, support for partial mini-block execution, and more.

2/ The Maiar DEX metrics have received an important update, to get its data from Elasticsearch instead of the transaction processor component, resulting in less strain on the system and enhanced performance.

3/ The highly anticipated Staking v4 is currently undergoing thorough internal testing. The goal is to eventually enable dynamic validator slot auctions, slashing for attempted attacks and other improvements to the Elrond Secure Proof of Stake mechanism.

4/ Other notable achievements:

- Refactored DEX metrics to use Elasticsearch index instead of transaction processor & retrieve balance from transaction history instead of account details
- Continued development & testing for the new launchpad version
- Staking v4 bughunt & fixes

5/ - Added the functionality to compute a transaction’s hash inside erdgo
- Continued working on Elrond API GitHub community standards
- Added erdcpp github actions & scripts for build and unit tests
- More tests for the ESDT transfer role & async calls

6/ - Finished updating the integration tests functionality with the latest enable epochs config handler - and continued its integration into final components
- Created a new ES cluster for logs aggregation
- Snapshots v2 improvements and bugfixes
