staking

Staking is a mechanism in blockchain networks that supports network operations and earns rewards by locking up cryptocurrency. Users deposit their tokens into specific smart contracts to help validate transactions and maintain network security. Staking is typically associated with the Proof of Stake (PoS) consensus mechanism, where participants gain governance rights and rewards by holding and locking tokens. It offers a relatively environmentally friendly alternative, avoiding the high energy consumption required by Proof of Work (PoW).

Solana staking protocol Marinade's staking volume for SOL increased to 7.94 million coins in the third quarter

Marinade, the Solana staking service protocol, released its Q3 2026 report. As of September 30, the amount of SOL staked was 7.94 million, a quarter-over-quarter increase of 21.2%, mainly driven by the non-custodial native staking product Native and the institutional-focused Select. The amount staked in Native increased by 47.3% quarter-over-quarter to approximately 3.77 million, while Select grew by 38.7% to about 1.68 million, and mSOL decreased by 6.8% to around 2.27 million.Revenue for the third quarter was approximately $1 million, corresponding to 10,918 SOL, a quarter-over-quarter increase of 25.9%, primarily from validator margin settlement income, which grew by 38.1% quarter-over-quarter. In the staking auction market, 48 out of 51 epochs in the quarter had yields higher than the Solana staking index, with an average yield before Marinade fees of 5.93%, compared to 5.67% for the index during the same period.In governance, since the implementation of MIP-22 in July, Marinade has used 10% of auction fees to repurchase MNDE on the open market. In the third quarter, a total of 4.2 million MNDE was repurchased with 906.6 SOL, and the first distribution opened on October 1. The report also disclosed that on September 25, attackers exploited a vulnerability in the DAO voting process to submit two malicious proposals, one of which involved transferring DAO treasury assets; the council vetoed both proposals within about 6 hours, and the fix was completed that night, with no funds being transferred.

first_img The Cardano Foundation urges the European Union not to extend MiCA regulations to DeFi and staking

The Cardano Foundation calls on the European Union not to introduce new independent regulatory rules for DeFi and staking, advocating that existing financial laws should regulate based on the function and risk of activities rather than the technology used. The foundation outlined its 19-page opinion submitted to the European Commission on September 30 in a blog post released on Wednesday, urging a distinction between direct participation in decentralized networks and financial services provided by intermediaries, especially those involving the custody or control of user assets. The foundation stated that regulation should follow the substance of the activity, the functions performed, and the risks generated, rather than the technology relied upon to conduct the activity.The foundation pointed out that Cardano users can delegate native ADA tokens to help secure the network without relinquishing custody or locking up tokens, and this form of direct participation should be treated differently from staking services operated by intermediaries. The opinion also calls for a clearer distinction between the EU MiCA regulations and existing financial laws, warning that overlapping regulatory requirements and inconsistent interpretations among member states could create uncertainty for crypto businesses.This move comes as EU regulators consider expanding oversight of crypto services. In September, the European Securities and Markets Authority suggested adding additional safeguards for staking and lending activities and establishing a new category of regulated services for companies providing access to DeFi protocols. Additionally, the Cardano Foundation, along with five other blockchain organizations, sent a joint letter to the U.S. Securities and Exchange Commission on October 20, urging it to formally recognize digital commodities as non-securities under the proposed crypto framework.

first_img NEAR has initiated voting to reduce the issuance rate to 1.6% over 24 months

The NEAR ecosystem governance proposal HSP-029 has entered the voting stage, proposing to gradually reduce the maximum annual issuance rate of NEAR tokens from 2.5% to 1.6%. This proposal was put forward by SVRN CEO Sal Ternullo, planning to linearly decrease by approximately 3.75 basis points per epoch over 24 months, while maintaining a 90/10 allocation ratio between stakers and the treasury. After the vote passes, there will be a 90-day grace period before the reduction officially begins.The proposal's calculations indicate that this plan is expected to reduce the issuance of approximately 11.8 million NEAR tokens over two years, with a cumulative reduction of about 66.1 million tokens over six years, equivalent to a 4.36% decrease in supply compared to the current situation. The annualized staking yield will gradually decrease from the current 5.268% to 3.372%. The author points out that this move aims to reduce the degree of dilution for non-staking holders and responds to discussions regarding the protocol's discretion risk following the withdrawal of the previous Sovereign Fund proposal.This proposal must go through a dual process to take effect: after passing the House of Stake vote, validators must also independently adopt it through the standard protocol upgrade process. The proposal cites Solana's SGP-0002, which was passed in August 2026 with a staking weight approval of 67.001% for a similar issuance reduction, as a precedent. Currently, the NEAR network has a total of 406 active validators, with a staking rate of 42.71%.

first_img Optimum Blockchain Transmission Layer mump2p launched on the Ethereum mainnet, ether.fi requires all nodes to adopt

A network startup company called Optimum, led by Professor Muriel Médard from the Massachusetts Institute of Technology, announced that its block propagation software mump2p has officially launched on the Ethereum mainnet. The Ethereum liquid staking protocol ether.fi has made mump2p a mandatory requirement for all 12 of its node operators, whereas previously the software was optional for its operators.Optimum stated that there are currently 16 node operators running mump2p in production environments, collectively managing approximately 22,000 validator keys and over 1.4 million staked ETH, accounting for more than 3% of the total staked amount on Ethereum. Partners include Blockdaemon, Everstake, P2P.org, Stakefish, and Bitcoin Suisse. The software operates in a sidecar gateway manner, not replacing Ethereum's default GossipSub, but rather overlaying it on top of libp2p and utilizing random linear network coding technology. Optimum claims that the block arrival speed is 2.42 times faster than GossipSub, with an approximately 7.88 times reduction in arrival time variance.Rok Kopp, co-founder and Chief Growth Officer of ether.fi, stated that they will not require the entire validator set to adopt a new infrastructure unless they are confident that it can enhance the overall level of stakers and the network. Médard mentioned that traditional financial institutions invest billions of dollars to shorten execution times to the millisecond level because speed is money. Optimum launched its private testnet in June 2025, having previously completed a $11 million seed round financing led by 1kx, and plans to expand the protocol to other high-throughput blockchains after Ethereum.

first_img Lido engineer warns of Glamsterdam staking deposit hijacking risk

Dmitry Gusakov, the engineering lead of the Ethereum liquid staking protocol Lido, warned at the developer conference ACDC #189 that the one-time builder access mechanism introduced by the Glamsterdam upgrade could interfere with the existing deposit protection logic of the staking protocol, leading to the hijacking of staking deposits. This issue involves multiple deposits sharing the same validator public key.According to Ethereum's current deposit rules, the first valid deposit determines the withdrawal credential, and staking protocols typically leverage this feature to prevent credential manipulation, such as initially depositing a small amount of ETH and then topping up the remaining funds once the expected credential appears. However, the special access mechanism introduced for builders by Glamsterdam may change the interpretation of subsequent pending deposits under the same public key during the fork transition period, putting the staking protocol at risk of a third outcome: the validator does not appear, and the deposited ETH is credited to the builder.Lido's proposed fix is to maintain the distinction between validator deposits and builder deposits during the one-time access process. However, core developers rejected this modification on the grounds of timing, mainly because the Sepolia testnet has already been activated according to existing specifications, and the Hoodi client version is also in preparation. Changing the behavior at this point could require redeploying Sepolia and conducting additional testing. The issue affects the access process during the fork transition period, rather than the ongoing deposit processing rules, but its consequences could impact deposits waiting in the queue.

first_img Lido will directly expand ETH staking to four Layer 2s

Lido announced the integration of direct ETH staking functionality for Arbitrum, Base, Linea, and Optimism Layer 2 networks into its official staking interface, which was announced on October 15. This process is supported by Chainlink's cross-chain interoperability protocol CCIP, allowing users to directly obtain wstETH on the originating network without manually transferring ETH across chains to Ethereum and back.Lido stated that users' ETH will be exchanged for wstETH through dedicated liquidity pools on the same L2, with the Chainlink price feed reflecting the exchange rate of the Lido protocol rather than the exchange market price. The underlying staking still occurs on the Ethereum mainnet: the ETH deposited by users on L2 will automatically be transferred to Ethereum and staked through Lido, after which wstETH will be sent back to replenish the local liquidity pool. Users receive the wrapped version of stETH, wstETH, which maintains a fixed balance while its value reflects staking rewards.This functionality integrates existing cross-chain infrastructure into Lido's own interface. Lido previously introduced relevant channels for Arbitrum, Base, and Optimism in October 2024, with third-party frontends including XSwap, OpenOcean, and Interport, while Linea followed up in October 2025. In terms of fees, users will still need to pay L2 transaction gas, and cross-chain costs come from the separately funded contract balance rather than staker deposits;
