X Day will be a unique and remarkable moment.

Showcasing meaningful progress and milestones around research, architectures, products, and ecosystem, all tied to the extraordinarily passionate Elrond community.

It's a new beginning. Unfolding on November 3.
Weekly #elrondtech 🛠️

1/ Implemented a new heartbeat v2 sender which will only work during bootstrap. It also includes the number of trie nodes synced in order to provide live data on explorer.

2/ Added several missing protocol transactions and SCR fields from API transactions. Some of them were mandatory for external clients to re-create protocol transactions (e.g. validate transaction signature based on transaction version + options)

3/ Worked on multiple rarity algorithms for NFT service (trait, statistical, OpenRarity's, Jaccard Distances), custom rank support & rank sorting and integrated payment tokens filtering

4/ Other notable achievements:
- Documented two steps improvement proposal that should decrease transaction time to finality by more than 50%.
- Performed audit on multisig and addressed minor findings
- Refactorization on 2FA service

5/ - Elrond API account contracts labeling and bugfixes
- When getting a value from a data trie, also return the trie depth from which that value was retrieved
- Started working on two new smart contracts: Seed NFT minter and Rewards distribution
- Maiar Launchpad testing

6/ - Mainnet crawler cleanup preparations and testing
- Fixes on backward compatibility issues found on the rc/v1.4.0
- Started integration of altered accounts in proxy
- If a trie node is missing from storage, sync it from the network

7/ - API status checker metrics
- Deployed smart-contract validation per transaction. Working on smart-contract validation per address
- DEX internal trackers bughunt & refactoring
- Fixes on heartbeat v2 direct connections discovery method, prepared releases

8/ - Finished current refactor / fixes after review on scr processor
- Implemented "bytes consumed by tx as networking" counting for vm output
- Mainnet crawler cleanup
- Inspire testing

9/ - Extended node's contributing and pull request template to better illustrate the branches' management
- erdjs-tokens (still a private repository): continued implementation & examples page
- Rosetta: construction of ESDT transfers, tests
- Fix empty trie root hash

10/ - Local testnet scripts fixing
- Started the implementation of overridable node config.toml 's parameters - to be used by node operators when they want to keep some of the settings after a node upgrade
- Install command in the Elrond Visual Studio Code extension

11/ - Investigations regarding github actions build issues when installing twiggy
- Added an optional parameter notarizedAtSource for hyperblocks, with the use-cases of fetching pending (live) transactions instead of finalized transactions
- Rust debugger pretty printer script

12/ - System test scripts improvements
- Added a new CLI flag for the node: --operation-mode , which can alter the configuration in regard to different use cases (full archive, historical balances, and so on)
- Completely removed heartbeat v1 code
- Split playground worker & API

13/ - Moved the node's webserver antiflood configuration in a different structure + small fixes on this area
- Continued working on MEX 2.0 integrations on DEX service
- Fixes on the delegators index in order to have correct values
- Bugfixes on NFT services

14/ - Continue working on the web-socket indexer (testing and bug-fixes)
- Started integration of altered accounts in proxy
- Started audit for feat/optimise-consensus-sigcheck
- Integrators and developers community support in regard to the latest mainnet upgrade

15/ - Fixes and testing for the altered accounts API endpoint
- New alerts and dashboards for microservice monitoring
- Finalized the working VM executor prototype with Wasmer 2.2 integration
- Prepared erdjs for v12.0.1 and erdjs-walletcore for v3.0.1 releases

16/ - Fix the logs&events generated for the creation of a new delegation contract
- Documented guardians support for erdjs
- Finished engineering metrics integration
- Play worker moved outside kubernetes

17/ - Research accountable bridges with zk-snarks
- Investigations and fixes on failing tests
- Shadow fork transaction sorting
- Trie and crawler statistics

18/ - Deep-history: redesign setup (for easier installations)
- Reproducible builds: minor fixes.
- DEX analytics data import
- Data API improvements
- New rate limiters on API's

19/ “Stay Hungry Stay Foolish” and tune in soon for more of the #elrondtech which powers the @ElrondNetwork ecosystem.
