.@ElrondNetwork It's the end of another week and this is the weekly tech update. Elrond #BUIDLs 🛠️
See below ⬇️⬇️
1. Preparations for the Battle of Nodes (improvements, bugfixes, benchmarks, tests)
2. Initial implementation of a System VM and smart contract for validator staking, that will allow nodes to join the network real-time, through a fast protocol built-in mechanism
3. VS Code extensions can handle WASM smart contracts written in C and Rust. Work in progress to enable debugging of such code in the IDE
4. First flood attack on our testnet v1.0.19 made us tweak the libp2p's parameters and craft additional anti-flooding capabilities
5. Fixed the arm64 build so we can now run validators on raspberry pi4
6. Refactoring of shard processor in order to remove duplicate code and group all arguments in a single structure
7. Snapshot of the trie for saving the current state of the trie in a separate database.
8. Compaction of miniblocks to allow us to add more transactions in a block and decrease the data that needs to be propagated to metachain. Throttled mini blocks creation to a defined maximum value, to avoid bottlenecks with blocks with a too higher number of miniblocks
9. Added a local cache of meta blocks, used for processing current shard block, to avoid situation when a full pool of meta blocks (happening especially when a node is bootstrapping), would generate situation when needed meta blocks are in fact evicted from pool
10. Validator's uptime statistic improvements for the Battle of Nodes
11. Added more data in Elastic Search related to consensus group, will be visible in the testnet explorer
12. Economics rewards metrics for termui. Soon an estimation of how many ERDs you can earn
13. Fixed bug that caused in some situations the block to be rejected due to missing reward transactions
14. Fixed a bug after merging with the economics part which didn't allow the node to start
15. Further bugfixes and improvements

The main sharding concerns boil down to myths busted long ago when our design implementation went live.
In our perspective, the only sharding concern is the Web3 space not progressing anymore so that the need for more scale dries up.
Weekly #multiversxtech 🛠️
1/ [releases] Mainnet v1.7.13.0 release
[relayed transactions] Further fixes on relayed fees
[state] Added multiple tests and fixes for the trie updates batching
- Added testing scenarios for the new esdt built-in functions
2/ [sovereign] New sovereign deploy scripts + docs released and tested
- Analysis for genesis block transactions to be correctly displayed
- Resolved a bug where Native ESDT was displayed as issued token
- Bughunt for delegation contracts
Reaching Web3 quantum quorum by creating the infrastructure to unify protocols, bring enhanced efficiency and parity in features and experience for the majority of on-chain users.
All top networks, 1 integrated ecosystem. Enabled by Sovereign Chains.
Weekly #multiversxtech 🛠️
1/ [releases] Testnet reset T1.7.10.2
- Testnet release T1.7.11.0
- Devnet release D1.7.11.0
- Prepared mainnet release v1.7.11.0
[mx-chain-es-indexer-go] Indexer performance testing
[mx-chain-simulator-go] New endpoint that can trigger an epoch change
2/ [staking-v4] Staking v4 scenarios testing
[relayed transactions v3] testing + added more integration tests
- Updated logs processor to save all the log events generated by failed inner transactions
- Updated sdk-go builder for multiple inner transactions
The #MultiversX hackaton is inviting devs from all over the world to build products, integrations & tools for the ecosystem.
With up to $1M in prizes and funding, this is the perfect moment to start building.
Weekly #multiversxtech 🛠️
1/ Part of the xExchange off-chain governance process & as a new community channel for debates, feedback and improvement proposals, we have launched the Agora forum.
Get involved in the trajectory of the protocol, there already several topics brought up: agora.xexchange.com
2/ A new Ledger app version for MultiversX has been released. The main highlight in v1.0.23 is the support for guarded accounts, alongside code improvements, custom messages, lintex fixes, and test updates to match with the latest Ledger libraries.
The xLaunchpad is ready to accommodate both EGLD & XMEX holders.
Great amount of meticulous testing has gone into preparing components for the next days and weeks.
Weekly #multiversxtech 🛠️
1/ The Guardians feature will soon become publicly available for everyone for an extra security layer. Among recent improvements: changed the rate limiter implementation for otp codes trials in TCS service and added extra info on responses for a better wallet UX.
2/ First working version which simulates incoming token transaction balances mainnet <> sovereign shard, which means that ESDTs & NFTs can now be bridged over. Lots of refactoring and cleanup underway.
2/ Enabled transferability between wallets for XMEX. A dedicated Escrow SC has been deployed to allow users to send single and multiple positions of XMEX, withdrawable after a 30-31 day period.
1/ Releases across the MultiversX protocol and several services now follow a new procedure with feedback window and an easier to follow and understand format.
More details & notes of the first release in this series, Polaris v1.4.8, can be found here: multiversx.com/releases/relea…
2/ xPortal entered the final phase before go-live. We've performed several infrastructure preparations and load tests, in order to ensure a smooth transition.
