Solana ecosystem R&D company Anza announced that the Alpenglow mainnet test version will be activated on October 21, 2026, at 14:50 (UTC). After the upgrade is completed, transaction finality is expected to shorten from approximately 12.8 seconds to 150 milliseconds.Alpenglow will replace the existing TowerBFT voting mechanism with Votor, allowing validators to not write every vote to the chain but instead confirm consensus through direct communication and summarizing into smaller records. The network is expected to maintain the existing system for about 18 minutes, switching to Votor after staking SOL reaches 82% of the validator set. Another component of Alpenglow, Rotor, will adjust the distribution method of new blocks among validators, but the activation date has not yet been announced. This upgrade only includes Votor, and Solana will temporarily focus on the replacement of the consensus mechanism.

According to CoinDesk, Solana plans to implement the Alpenglow upgrade on October 21. This upgrade aims to reduce the transaction finality time to about 150 milliseconds and replace the existing voting system of the network with a faster certificate-based consensus mechanism.

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.

Decentralised.co published a discussion on the path of stock tokenization, stating that the exposure to on-chain stocks held by traders and investors through tokenization and synthetic perpetual contracts has exceeded 6 billion dollars. The total market size of on-chain stock tokens is 3.21 billion dollars, with a 10% increase over the past 30 days; the open interest of perpetual contracts for stocks, indices, and ETFs on trade.xyz is 3.01 billion dollars, accounting for 94% of the total stock token market size.The process of stock tokenization is divided into four stages: initially, it is mostly offshore packaged certificates, followed by becoming collateral, then brokers tokenizing the shares that users already hold, and finally, the company registering the shares themselves on-chain. Most stock tokens are debt certificates that do not include voting rights or ownership of shares. Taking Robinhood as an example, after the related entity purchases shares and they are held by a custodian, it issues debt securities corresponding to one share to users, with dividends reinvested and stock splits adjusting the number of shares represented; if the issuer fails to perform, the securities agent will sell the shares and pay the holders, while the issuer can only maintain the price through arbitrage within a limited time frame.The market size of the top 100 tokenized stocks increased from 2.09 billion dollars to 3.03 billion dollars within 90 days, and the number of holding addresses grew from 417,000 to 4.21 million, with Binance and Robinhood contributing 86% of the new addresses. About 97.5% of the addresses hold less than 100 dollars, with exchanges and large wallets holding most of the value. The borrowing rates for collateralized loans against related stock tokens on Kamino, Jupiter Lend, and Ether.fi are approximately 4% to 5.75%.

The blockchain network Solana plans to reduce the target block time from 250 milliseconds to 200 milliseconds when it enters Epoch 1053 on Friday, completing a series of reductions that began from 400 milliseconds in August.This upgrade will allow the network to produce 5 blocks per second while lowering the computational limit for each block to keep the overall processing capacity roughly unchanged. Faster block generation may reduce transaction delays and transaction arbitrage activities, but it will also increase the demand for validator voting, put pressure on network connections, and shorten the transaction validity window.

According to Fortune, AI real estate technology company EliseAI announced that it has completed a new round of financing of $350 million, with a valuation of $4 billion. Andreessen Horowitz (a16z) and Bessemer Venture Partners jointly led the investment, with existing investors Sapphire Ventures and Navitas Capital participating.This is the fourth time the company has received investment from a16z and Bessemer since 2023, just about 13 months after its previous round of $250 million Series E financing.It is reported that EliseAI's software currently mainly provides automated rental for homes, tenant services, maintenance requests, and lease renewals, covering about one-sixth of apartments across the United States. This new financing will be used for product development and to expand EliseAI's engineering, deployment, and sales teams in North America.

Polygon co-founder Sandeep posted on the X platform stating that the POL community has recently accumulated and permanently destroyed 100 million POL through on-chain revenue, accounting for about 1% of the total supply, and will additionally destroy approximately 25 million POL.Sandeep also mentioned that POL (formerly MATIC) is still "the most undervalued and overlooked project." According to him, Polymarket has launched perpetual contracts on Polygon, and with the recent upgrade, Polygon PoS is gradually evolving towards a more advanced blockchain, expecting to achieve a 1 millisecond confirmation time through block flow in the future. Additionally, OMS is about to enable Polygon to handle approximately 1 million new transactions daily.

According to CoinDesk, the Solana consensus upgrade Alpenglow has completed the switch to Testnet and Devnet on September 24 and 25, respectively, and is currently running on the two major public test networks, allowing application teams to test compatibility before launching on the mainnet. Alpenglow aims to reduce the final confirmation time from about 12.8 seconds to approximately 150 milliseconds by allowing validators to exchange votes directly instead of writing votes as transactions into blocks, enabling consensus to be reached within one to two rounds of voting.The Solana Foundation reminds that the transaction statistics containing validator votes may decrease after the upgrade, but user payments and transaction volume may not necessarily decline; applications that simply send transactions and read account balances do not need to migrate. The 150 milliseconds is a simulated target and has not yet been validated in a real mainnet environment, and wallet processing and exchange deposit confirmations may still increase waiting times. The exact date for the mainnet launch has not yet been announced.

The Alpenglow upgrade of the blockchain network Solana has entered the public testnet, where developers will test reducing transaction finality from about 13 seconds to 0.15 seconds, or 150 milliseconds. This upgrade will replace Solana's existing TowerBFT consensus system with Votor, allowing validators to confirm blocks through one to two rounds of direct voting, but the way users send funds will not change.The first testnet migration requires using Agave 4.3 and does not currently support Firedancer or Frankendancer. The mainnet update on September 28 is still a tentative arrangement and not a confirmed launch date for Alpenglow.

On September 18, Solana reduced the target slot time from 300 milliseconds to 250 milliseconds, marking the third acceleration since August. As the computation and data capacity per slot is proportionally reduced, the overall throughput of the network has not increased.This adjustment is the third phase of the SIMD-0525 four-phase plan, with slot time decreasing from 400 milliseconds at genesis to 350 milliseconds, then 300 milliseconds, and now to 250 milliseconds. The final step down to 200 milliseconds has not yet determined a mainnet activation date, provided that the validator block skipping rate remains stable.

According to Decrypt, Solana will shorten the target block time slot from 300 milliseconds to 250 milliseconds on Friday, increasing the block generation frequency by nearly 17%. The computational resources and data available for each time slot will be correspondingly reduced, while the overall transaction processing capacity of the network remains unchanged.This adjustment is the third phase in the four planned stages of the SIMD-0525 proposal. The block production permission window for validators over four consecutive time slots has been reduced from 1.2 seconds to 1 second, and the expected duration of the epoch fixed at 432,000 time slots has been shortened from about 36 hours to about 30 hours. The next phase aims to further shorten the time slot to 200 milliseconds, but the mainnet launch time has not yet been determined, with the implementation condition being that the block skip rate remains stable.

Decentralised.co reported that the cost of sending $200 across borders is currently 6.36%, down from 9.67% in 2009, with the United Nations aiming to reduce it to 3% by 2030. Remittances consist of three parts: collecting from the remitter, transferring value, and paying the recipient, with the intermediate stage previously being slower and now the cheapest part. Receiving and paying require licenses, bank accounts, compliance, and payment networks.

Jacob Creech, Vice President of Technology at the Solana Foundation, stated that Solana has officially shortened the slot time for the first time since its establishment, now entering a new phase of 350 milliseconds, with the next target being 300 milliseconds.Slot time is the time unit corresponding to each block in the Solana network, and shortening it helps improve transaction confirmation speed and network throughput. Previously, Solana's target slot time had long been maintained at around 400 milliseconds, and this adjustment marks an important update to the network's performance parameters.

Solana developer Brennan Watt announced on the X platform that the Solana mainnet has activated the first slot time reduction, with the target decreasing from the current 400 milliseconds to 350 milliseconds, which will officially take effect in the 1020th Epoch.Watt pointed out that some SDK constants (such as DEFAULT_MS_PER_SLOT) have not yet been updated to the new values and will be pushed in subsequent versions. The transition period may affect applications that rely on SDK constants matching the mainnet reality, and developers are advised to manually determine whether the functionality is enabled based on Epoch boundaries when it takes effect. Watt explained that the long-term plan is to put these parameters on-chain for client queries, but currently, to launch the reduction feature as soon as possible, this transition period must be endured.

According to Cointelegraph, Sei has released the Giga white paper version 2, which aims to bring finality under 250 milliseconds, pre-execution privacy protection, protocol-level MEV resistance, and a processing capacity of over 200,000 transactions per second.

NEAR officially announced the next major protocol upgrade SPICE (Separation of Consensus and Execution), which is a key step towards Nightshade 3. After the upgrade is completed, the NEAR block time will be reduced from the current 600 milliseconds to 200 milliseconds, achieving about a 3x speedup, approaching the maximum speed allowed by physical conditions. The core of SPICE is to decouple the consensus layer from the execution layer, allowing validators to complete block consensus without waiting for transaction execution, thereby reducing latency and supporting more complex, time-consuming transactions.NEAR stated that this upgrade will be the largest underlying architecture change since Stateless Validation in 2024. After the upgrade, the transaction experience of applications such as NEAR Intents and near.com will be further enhanced. Defuse Labs CEO Alex Shevchenko indicated that the final confirmation time for NEAR is expected to drop to about 0.4 seconds, faster than Visa's standard of about 3 seconds, achieving a payment experience close to "completed in the blink of an eye."NEAR also mentioned that faster block times are crucial for the AI Agent economy, enabling high-speed payments and complex transactions between agents, and allowing longer tasks to be executed across multiple blocks. Additionally, SPICE will pave the way for Nightshade 3 and lay the foundation for achieving cross-shard atomic execution in the future. The NEAR development team stated that this will help address the development complexity and potential vulnerabilities brought by asynchronous environments, improving network scalability and security.

According to CoinDesk, the French Lightning Securities Exchange (Lise) plans to list aerospace parts supplier ST Group on its platform, which is expected to become Europe's first fully on-chain initial public offering (IPO).Lise was authorized last year under the EU's Distributed Ledger Technology (DLT) Pilot Regime and is the first institution in Europe approved to operate a fully tokenized equity exchange. Headquartered in Paris, it has the support of French financial institutions such as BNP Paribas, CACEIS (a subsidiary of the Agricultural Credit Group), and Bpifrance. ST Group primarily produces composite material components for aerospace, defense, and space projects, with potential project revenues estimated at around €59 million (approximately $68 million) over the next decade.Lise aims to provide a lower-cost and more efficient listing path for small and medium-sized enterprises, replacing the lengthy and expensive IPO process in traditional capital markets. Tokenization technology enables faster trade settlement and more efficient ownership tracking, and Nasdaq and NYSE have previously disclosed plans for tokenized securities trading.
