MultiversX Validators Announcements

📣 TESTNET Upgrade T1.3.21.0 & Important Node Disk Space Info Hello Validators, We are upgrading the TESTNET. We upgrade the nodes and KEEP the database. This release brings an update which improves our ongoing implementation of the Elrond <> Ethereum bridge. 💾 Important Disk Space Info Please remember that the current protocol version is "disk hungry" as we already mentioned in this post: https://t.me/ElrondValidatorsAnn/467 In addition to the suggestions above, we also recommend the following: Some validators have already had issues with the /tmp directory increasing in size. If your disk usage is high, you can check the size of the /tmp directory by running sudo du -sh /tmp If there are directories with a naming pattern like trieSyncStorage* they can be safely removed in order to free up some space. We will address storage topics in a future uprade. ⚠️ Do not upgrade your mainnet validators! You risk getting jailed and jeopardizing the mainnet. 👉 Let’s upgrade our TESTNET VALIDATORS.

🚜 Battle of Yields Bridges 2: The Sequel. $5,000 USD to be won, test the Elrond <> Ethereum bridge It's time to test the Elrond <> Ethereum bridge some more. We will test it by getting funds on the Ropsten Ethereum testnet, bridging them to the Elrond public testnet, and then bridging them back. 💯 - We learned the lessons from last time. Over-demand on the Ropsten side is not great. So, we will start with a batch of 100 users at first. Up to 1500 users will be able to participate, first come, first served. ⚠️ After 100 users get funds from the faucet, it will display a message saying "The number of users reached, come back for the next wave." That's whe you know the faucet has stopped disbursing funds. Stay tuned for the announcement about when it resumes and how many users can claim. ⏱ Complete tasks by Saturday 09 April (today) 23:59 UTC. 🚿 Phase 1: claim funds from the faucet. • Get the Metamask browser extension from your browser's store • Go to https://testnet-bridge.elrond.com • Click on "Faucet" (bottom right) • Connect to your Ropsten Ethereum testnet account with Metamask • Connect to your Elrond testnet account with Maiar DeFi Wallet, Maiar App, Ledger or Web Wallet • Complete the Captcha 💡 You can request 0.1 rETH, 10000 USDC, 1 EGLD every 24 hours • Import this USDC ERC20 token contract into Metamask: 0x085D9Bd3Ec26d1a9fC60c856549C50670e864E1E ❔ New to Metamask? FAQs here. 2️⃣ Bridge USDC from Ethereum to Elrond: • Go to https://testnet-bridge.elrond.com • Select From "Ethereum" • Select To "Elrond" • Select an asset "USDC" • Enter amount "3000" • Click on "Connect source wallet" and: ¤ sign into the Metamask wallet where you got funds from the Faucet ¤ sign into the Elrond wallet where you got funds from the Faucet • Click on "Confirm Swap" • On Metamask click "Confirm" on the popup • Wait for the Ethereum TX to procezz 💤 • Again on Metamask click "Confirm" on the popup • Wait for the Ethereum TX to procezz 💤 ⏳ Bridge transactions are executed in batches, which happen once every ~15 minutes. A countdown is displayed - keep the page open and return to it once the countdown is over. 🕵️‍♂️ You will see the transaction hashes, one on Ropsten Etherscan and one Elrond Testnet Explorer. The one on Elrond will likely include more transactions, as they are batched. Check the one for your address to confirm. 🔎 Click on "Start Over" or return to the bridge page, and click on the "Explore swaps" link below. Search for your Ethereum address, and then for your Elrond address, to confirm the transactions are also registered there. 3️⃣ Now perform a bridge transaction from Elrond to Ethereum, using the instructions above, but selecting from Elrond to Ethereum. 4️⃣ After you complete 3️⃣, send the USDC tokens from Ethereum, and the remaining rETH, to 0x51CeaFC9ecF82E0ac6BfdD4E1DaBeF159429d026 (back to the Faucet address) 💰 The $EGLD rewards for participants will be delivered to the Elrond addresses used in the bridging process, on the mainnet. 👏 Prizes for this event are offered by our staking provider partners Rosetta Staking and Disruptive Digital. 🌐 Testnet Bridge | Bridge Testnet Faucet | Testnet Explorer | Testnet Web Wallet | Maiar DeFi Wallet

📊 The latest release is disk hungry. Monitor your available storage to avoid getting jailed. Hello Validators, elrond-go v1.3.13.0 utilizes more disk. This is due to an important change to how trie data is written to disk, which is now done in the same way that transactions, blocks, etc are written to disk. Validator nodes that have been assigned less storage than the recommended 200 GB per node might see their disks rapidly filling up. When the available space goes to 0, the node will fall out of sync and get jailed. A future release will deal with trie pruning and bring further optimizations to how disk space is used. 👉 Please do: • check your servers and make sure enough storage is provisioned, according to the official recommendations: https://docs.elrond.com/validators/system-requirements/ • make sure you use monitoring, that your alerts are properly configured and working, and that you have a contingency plan for provisioning more storage. Check out these guides: • Prometheus by Easy2Stake • Zabbix by Palmtree Network & Arcstake Last resort: delete old databases, such as epochs 0 through 600. cd elrond-nodes/node-x/db/1 - replace x with 0, 1 etc rm -rf Epoch_y* - replace y with 2, 3, etc Again, deleting data is the last resort and should be used with the utmost care.
