Nillion announced on platform X that its L2 network will soon cease operations and reminded users holding NIL or ETH to transfer their assets to the Ethereum Layer 1 network (L1) as soon as possible before the network shuts down.

Unified Account Protocol Clovis announced that the private mainnet is now live. Clovis integrates revenue, cross-chain assets, and collateralized lending into a single unified account, allowing users to deposit assets on supported chains and transfer assets between chains.According to the official statement, users can use eligible positions to natively borrow assets in the market built on Morpho on Base.

Galaxy Research released a research report on October 15, categorizing decision markets and impact markets as conditional markets. These two types of conditional trading settle only when specific outcomes occur, and decision markets also settle on clear and binding results. Unlike prediction markets, conditional markets are not limited to binary, all-or-nothing structures; they trade real assets and their prices rather than synthetic probability contracts, with the byproduct being the impact of events on asset values rather than occurrence probabilities. The agency referred to prediction markets as the zero version of event-driven finance, with a large number of experiments emerging over the past 18 months, and new infrastructure pushing it beyond prediction markets.The ownership token-based issuance platform Umia, aimed at EVM-compatible chains, launched in September, expanding decision markets from being primarily limited to Solana, where MetaDAO was the first to scale binary pass or fail markets, to multi-outcome markets that can price proposal parameters. A deposit of stablecoins or DAO tokens can simultaneously convert into positions covering each outcome, with only winning market trades ultimately settling. Currently, 22 DAO treasuries fully governed by decision markets hold a total of $50.5 million, with MetaDAO accounting for 21 of them and 78% of the assets; the stablecoin portion is $35.8 million, with MetaDAO holding 82%. The fundraising for the market-governed DAO issuance platform by MetaDAO was approximately 11 months prior to this research report. Umia extends the issuable chains to Solana or EVM, which together account for about 92% of TVL by chain type.

According to The Defiant, the Solana development team Anza has scheduled the migration of Alpenglow's mainnet Beta for approximately 10:50 AM Eastern Time on October 21 (Wednesday), at which point the new consensus system will replace TowerBFT, aiming to reduce the final confirmation time for transactions to about 150 milliseconds. The Solana Foundation's upgrade guide indicates that the final confirmation time under TowerBFT is about 12.8 seconds. Final confirmation refers to the point in time when a transaction can no longer be rolled back, rather than the block interval.Alpenglow's Votor voting protocol no longer submits votes as on-chain transactions; instead, messages are sent directly between validators and aggregated into certificates, allowing blocks to be finally confirmed after one to two rounds of voting. The removal of voting transactions from blocks also frees up block space for users, while the execution and fees for user transactions remain unchanged. This upgrade had previously completed the migration of the testnet and development network in September, and the mainnet functionality switch has not yet been activated. According to Anza's activation policy, the new version of the software must be adopted by 95% of the staked amount for two epochs before it can be activated on the mainnet.The migration plan separates the activation of the functionality switch from the handover itself: the functionality switch is activated at the epoch boundary, and after 5,000 slots, blocks will pause carrying user transactions and will only contain votes. Validators will then establish the Alpenglow genesis certificate supported by 82% of the staked amount, roll back blocks containing only votes, and then restore user transactions with Votor. Anza expects the handover to take several hundred milliseconds.

Mysten Labs reports that the Sui network has completed its first native post-quantum Devnet transaction. This Devnet implementation introduces the ML-DSA-65 account signature, allowing accounts to authorize transactions directly using this post-quantum signature scheme. ML-DSA-65 belongs to the ML-DSA series defined by the National Institute of Standards and Technology (NIST) FIPS 204 standard, and Sui uses it as the native protocol signature scheme for everyday accounts.Sui is also planning to introduce a hash-based SLH-DSA-SHA2-128s (FIPS 205) for high-value vaults in Move smart contracts. The two schemes are based on lattice-based and hash-based mathematical problems, respectively, so a weakness in one scheme will not affect the other. Since Sui keys are deterministically derived from seeds, users can migrate to post-quantum keys using existing mnemonic phrases; the already launched address aliases allow accounts to update authorization keys without transferring assets.Post-quantum accounts are being rolled out in an optional, incremental manner, following the online path of zkLogin and passkey. Sui states that the goal for the post-quantum vault is to go live on the mainnet within this year, with the native ML-DSA-65 accounts aiming to enter the testnet by the end of the year, and the mainnet native account authentication goal set for the first quarter of 2027, with the final timeline depending on independent audits and testnet feedback.

According to official news from Aptos, the Aptos mainnet has officially launched the Encrypted Mempool feature. Users can choose to encrypt pending transactions before block finalization, keeping the transaction call functions and input content encrypted before execution, while the sender's address and fee information remain visible to the outside.This feature is mainly aimed at institutions (to avoid exposing intentions of large orders in advance), traders (to reduce MEV arbitrage risks), and AI entities (to ensure transaction inputs remain private before execution).

Ontology announced that the investigation into the security incident of the ecological project has concluded, and its mainnet has resumed block production and returned to normal operation. The core infrastructure of the Ontology network remains secure, and there has been no loss of funds on the network itself.The previous suspension of block production was a precautionary measure taken in collaboration with consensus nodes, aimed at facilitating the investigation and reducing potential risks.

The Solana client development company Anza posted on X that SIMD-0525 has been completed, and the 200 millisecond slot is now live on the Solana mainnet test version.Anza stated that the block landing frequency has reached twice that of the genesis, and the duration of one epoch has been shortened from about two days to about one day. Anza was formed by the original core engineering team of Solana Labs and is responsible for maintaining the Solana validator client Agave.

Starknet published an article introducing the Quantum Secure Bitcoin solution (QSB), stating that StarkWare researchers have verified a quantum secure locking mechanism on the Bitcoin mainnet that does not require a soft fork, new opcodes, or modifications to consensus rules. The first QSB output was completed on August 26, 2026, in Bitcoin mainnet block 964,199, with related GPU computing costs dropping from approximately $320 to about $50.QSB constructs the locking mechanism through hash calculations, but each transaction still requires significant computation, and assets transferred into this solution still need to undergo traditional transactions that are subject to quantum risks. This transaction does not comply with the default relay rules of Bitcoin Core, and currently, there are no accompanying wallets, address formats, or recovery processes. StarkWare stated that QSB is an emergency research solution, and a long-term solution will still need to introduce post-quantum signature mechanisms through a soft fork. The comprehensive quantum security of Starknet also depends on the progress of Ethereum's underlying upgrades.

Sui posted on platform X that the Hashi mainnet will gradually go live this month, with over $500 million in capital commitments already secured.Anchorage will join as a launch partner to provide qualified custody services and stablecoin liquidity for Hashi.

Core contributor of the Ethereum Economic Zone (EEZ) Eduardo Antuña posted on the X platform, stating that the Ethereum mainnet has successfully executed the first atomic cross-chain transaction from L1 to L2, marking the official implementation of atomic synchronous composability on the mainnet, no longer remaining in the theoretical stage.Eduardo Antuña pointed out that this is just the starting point for EEZ to promote cross-layer synchronous interaction and liquidity unification in Ethereum.

According to Cointelegraph, Zcash has activated the NU7 network upgrade on the testnet, putting the planned protocol changes into real testing, about a month away from its target mainnet launch. According to data from the Zcash testnet block explorer ZecBlock, the scheduled activation height block 4,465,026 for NU7 was mined on October 4 at 18:21:45 UTC, and Zcash subsequently confirmed on the X platform that NU7 is running on the testnet.NU7 is the next network upgrade for Zcash, which will shorten the network's target block interval from 75 seconds to 25 seconds. This upgrade will also disable version 4 transactions and introduce a network sustainability mechanism that recycles part of the transaction fees for future block rewards. Disabling version 4 transactions also means that if users do not transfer funds before NU7 is fully activated, ZEC stored in the old Sprout shielded pool of Zcash will be unspendable.The Zcash Foundation stated that testnet operators should test NU7 under real conditions using the candidate version, allowing developers to evaluate the upgrade before mainnet activation. Zcash developers plan to make a final decision on mainnet activation and determine the activation height based on the testnet performance on October 20, with a target mainnet activation date of November 5.

According to Bitcoin.com, the Ethereum Foundation and Open Anonymity Project have launched zkAPI on the Ethereum mainnet. This system allows users to pre-deposit amounts in ETH, USDC, and other currencies, separating billing identity from requests when paying for AI and other usage-based services.After users deposit funds, they can authorize payments using zero-knowledge proofs and one-time API keys. After the server verifies the payment proof, it generates a short-term key with a set limit, allowing AI service providers to receive prompts without knowing the corresponding payment identity.zkAPI does not hide the content of the prompts; AI service providers can still read the prompts and responses; stable IP addresses, time patterns, and repetitive behaviors may also be linked to user identities. The project repository marks zkAPI as an experimental project.

Layer 2 network Blast announced that it will cease operations due to the ongoing maintenance costs of the network exceeding the revenue generated by L2. The team believes there is no credible path to achieve economic sustainability.Blast advises all users to withdraw on-chain assets and balances in the Blast PWA to the Ethereum mainnet and plans to shorten the withdrawal waiting time to 24 hours. However, the team will first process the withdrawal of Lido assets held by Blast, which is expected to take about a week, during which the withdrawal function will be temporarily unavailable.Users can complete withdrawals through the regular Blast interface before October 26. After that, assets can still be withdrawn, but it will require direct interaction with the Blast Bridge contract on Ethereum L1. The team will announce specific operational instructions before the deadline.

According to The Block, the Ethereum Foundation has launched zkAPI on the Ethereum mainnet, a solution co-authored by Vitalik Buterin.zkAPI allows users to pay for artificial intelligence and other APIs using pre-stored ETH or USDC through zero-knowledge proofs, making it impossible for service providers to associate specific requests with the payer.

According to The Block, Base has completed its third mainnet upgrade, Cobalt. The core of this upgrade is the Validity Transactions conditional transaction feature, allowing users to submit transactions with conditions that must be met before they are packaged on-chain; if the conditions are not met, the transaction will never be included.Base stated that this API is part of a neutral infrastructure, allowing advanced traders to keep their submissions confidential before they are finalized.Cobalt also enhances the B20 token standard launched with the Beryl upgrade in June, adding three new features. Composite Policies allow asset issuers to combine existing whitelists and blacklists using "or" and "and" logic, without the need to duplicate lists or maintain off-chain synchronization.The Schedule Multiplier upgrade aligns with the ERC-8056 standard, supporting issuers in changing the display method of asset balances, which can be used in scenarios such as stock splits.Base also revealed plans to shorten block time from 2 seconds to 200 milliseconds in the coming months, implement native smart accounts at the protocol layer, support Gas payment and transaction batching, and introduce some EVM improvements from the Ethereum Glamsterdam upgrade.

Animoca Brands' projects Moca Foundation and Moca Network announced the launch of the Moca Chain mainnet, which supports users and AI agents in sharing verifiable credentials across different applications. Users can store credentials and decide when and where to share them.Moca Chain allows institutions to issue tamper-proof credentials associated with unified digital identities, covering information such as identity verification and membership. Moca Network also launched AIR, providing a unified entry point for businesses to access users and AI agents while reducing the need for sensitive information storage. Moca Network disclosed that the AIR ecosystem has incorporated over 9 partners, including SK Planet, Biletinial, Oyunfor, Open Campus, OneFootball, Automobili Lamborghini, Inveo Kripto, Plume, and Nansen, with plans to complete integration by 2026.

DyorSwap officially announced that the so-called "GIWA Mainnet" identified by the team earlier is actually a fake chain set up by scammers. This fake network used the correct GIWA chain ID (9134), making it appear legitimate during the initial verification phase.
