ChainCatcher news, according to The Block, the liquid staking platform Marinade Finance on Solana is discussing a governance proposal to address malicious validator nodes and democratize MEV (Maximum Extractable Value).Marinade proposes a "balanced" approach that reduces harmful MEV while fairly distributing related profits through an open market. The proposal suggests establishing a public committee to oversee delegation activities and blacklist malicious validator nodes. Additionally, it recommends reopening public trading pools to prevent MEV flow concentration in a few private trading pools and proposes funding for MEV research to enhance transparency and data accessibility.Researchers point out that the current centralization issue of MEV is worsening, particularly with sandwich attack behaviors threatening Solana's decentralization. Marinade hopes to seek community feedback through the governance proposal and ultimately vote and implement based on the opinions received.

ChainCatcher message, Saga posted on X reminding that: "The SG-1 (@sg1_online) account key has been compromised, but no funds are affected, and the network remains secure. A new SG-1 validator node is now online, and the foundation has unstaked 16 million Saga tokens from the old SG-1. If users previously delegated to the old SG-1, please re-delegate."

ChainCatcher news, according to Coindesk, the crypto investment firm Sol Strategies (HODL), led by former Valkyrie Investment Company CEO and co-founder Leah Wald, has acquired four validator nodes for nearly $18 million in cash and stock.The Toronto-based company, formerly known as Cypherpunk Holdings, plans to acquire these validator nodes from Cogent Crypto. Cogent Crypto is a high-performance validator node operator operating within the Solana ecosystem.

ChainCatcher news, the privacy public chain Namada announced that the Anoma Foundation is launching the Namada delegation program, with applications now open and a deadline of October 31, 2024. This program will be used to delegate up to 50 validator nodes. Accepted validators will receive a 6-month delegation from the Anoma Foundation to help with the network's decentralization, stability, and security.

ChainCatcher news, Hemera is building a programmable semantic data layer driven by an innovative account-centric indexing protocol. This data layer helps developers abstract the heterogeneity of smart contracts, allowing them to express new semantics through user-defined functions (UDFs).By leveraging AltLayer's Wizard and relying on Eigenlayer's infrastructure, Hemera is able to provide a verifiable data network in real-time. Hemera's complex state machine makes achieving verifiability through zero-knowledge technology impractical. However, with the shared security mechanism, Hemera's verification nodes AVS address this critical issue, making it a fully verifiable protocol network that provides Hemera's programmable semantic data network to all rollups and applications within and outside the Eigen ecosystem in a minimally trusted manner.Arthur Meng, founder and CEO of Hemera, stated, "AltLayer's Wizard product simplifies the development of AVS, helping development teams save months of engineering time and allowing developers to focus on building their applications. The AltLayer team possesses exceptional expertise and deep knowledge of the rollup and restaking ecosystem, assisting partner teams in tackling complex challenges from both technical and market perspectives. The Hemera team is very excited about collaborating with them in AVS development and other areas."Based on the Hemera protocol, developers can focus on specific business needs without the need to maintain an internal data team to handle on-chain data.

ChainCatcher news, Superfast founder Martin Tromp has launched a Solana validation node at the Teraco data center in Johannesburg. Solana is a fast, scalable blockchain platform that competes with Ethereum, and as a proof-of-stake (PoS) system, validation nodes play a key role in network security and transaction validation.Tromp initially deployed the node in Cape Town, but moved it to Johannesburg due to network latency issues caused by a submarine cable break. Despite being further from the coast, performance has improved at the new location thanks to hardware upgrades.

ChainCatcher message, according to tonscan data, the TON network has staked 646.9 million TON.In addition, the current staking APY is 3.9%, and there are a total of 386 validator nodes in the network.

ChainCatcher message, LayerZero Labs announced on the X platform that it will join the Humanity Protocol validator node network, using ZK proofs to authenticate credentials and ensure privacy. LayerZero also stated that it will launch on the decentralized framework Humanity Protocol.

ChainCatcher news, EigenLayer announced that it has lowered the staking threshold for EigenDA validator nodes from 320 ETH to 96 ETH.EigenLayer stated that this change will allow more new validator nodes to participate in EigenDA's AVS validation service; re-staking users can also choose to delegate their tokens to validator nodes with a lower total staking amount, thereby increasing the decentralization of the network; Rollups can achieve better performance support through a larger cluster of validator nodes.

ChainCatcher news, according to official sources, the gaming guild YGG announced that the YGG token will be launched on Ronin on March 21, 2024. Once launched on Ronin, the YGG token can be bridged between Ethereum and Ronin. The snapshot of wallets staking RON tokens through YGG validators has been completed, and a total of 1,376,579 YGG tokens will be distributed to 8,861 eligible wallet addresses to celebrate the YGG launch on Ronin.It is reported that by UTC time March 11, 2024, wallet addresses that delegate and stake at least 1 RON token in YGG will be eligible to receive YGG tokens. The amount of tokens airdropped will be determined based on the number of RON staked and will be tiered according to the duration of the token staking.

ChainCatcher news, according to the LUNC governance forum page, LUNC validator Allnodes has relinquished its voting rights on LUNC proposal #12073, which aims to burn 800 million USTC and blacklist and destroy the Risk Harbor multi-signature wallet valued at approximately 25.9 million USD (according to proposals 11660, 11710, 11832).It is reported that Allnodes is the top-ranked validator node in the LUNC network, holding 14.89% of the voting power. This vote will end on the 26th at 10 PM Beijing time.

In the blockchain field, an Oracle refers to an entity that connects the network with external systems, allowing smart contracts to execute based on external inputs and outputs. Google Cloud is one of the 100 organizations serving as Flare Time Series Oracle (FTSO).

ChainCatcher message, the dYdX trading research team collaborates with Skip Protocol to publicly display the amount of MEV that each validator could extract using a dashboard, aimed at preventing MEV extraction behaviors and taking action against bad actors.In addition, dYdX has deployed a "bad validator node" on the public test network, which maximizes profits by sandwiching all eligible orders.

ChainCatcher message, the Ethereum Goerli testnet activated the Shapella upgrade on March 15 at 6:26, with a validator participation rate of only 29% at the block trigger. In a YouTube live stream, Ben Edgington, the product lead for the Ethereum client Teku, stated that the low participation rate might be due to validator nodes not upgrading to the Goerli fork in time.Ethereum core developer Tim Beiko tweeted that the Goerli testnet is processing deposits, but some validator nodes have not yet upgraded. A challenge in studying the testnet validator nodes is that, given ETH has no value, the incentive to run validator nodes / monitor them decreases. Another possible reason is that a large number of withdrawal credential changes were processed at the fork point. Since this is the first time people are submitting these changes, there is more to handle, which may lead to block/proof loss on low-resource nodes.In addition, Ethereum developers will hold a conference call on March 16 from 22:00 to 23:30 to determine the mainnet Shanghai upgrade date.
