first_img Solana's largest network upgrade Alpenglow is online, with the final confirmation time reduced to about 150 milliseconds

Solana's largest network upgrade since 2020, Alpenglow, officially launched on Wednesday. This upgrade moves validator voting from on-chain to off-chain, packaging votes into certificates that can lock transactions within one to two rounds, aiming to reduce the final confirmation time for transactions from about 6 seconds to approximately 150 milliseconds, speeding it up by about 40 times. If this goal is achieved on the mainnet, Solana's transaction settlement speed will be faster than the blink of an eye, bringing it closer to the trading and payment experience of centralized exchanges.Currently, a 6-second confirmation time means that prices may change before the transaction is locked, causing exchanges and payment applications to wait before considering deposits as complete. In comparison, Ethereum takes about 13 minutes to achieve full final confirmation. At the same time, validator costs are expected to decrease by about 60%: currently, validators spend about 2 SOL daily on voting fees, which doubled after Solana recently reduced block time to about 200 milliseconds; Alpenglow eliminates voting fees, replacing them with a fixed validator entry fee of 0.8 SOL per epoch (approximately 24 hours).The upgrade launch process was not smooth. The testnet has been cleared and restarted from scratch six times since its launch in early May, with one migration failing across the entire network and having to be rolled back. According to an article published by Galaxy Digital, one of about 100 validator operators on the testnet, a subsequent migration was successfully completed, clearing the way for Wednesday's launch. Since these events occurred on a network built specifically for testing, there was no risk to real funds. The upgrade was scheduled to switch at the start of epoch 1064 on Wednesday, with actual changes occurring at slot 459,653,000 after a transition of 5,000 slots.

Aster updates the token unlocking plan, and RootData adjusts the data synchronously after official confirmation

Recently, the Aster team provided feedback to RootData regarding some adjustments needed in the previously released token unlock data. After receiving the feedback, RootData verified the information against Aster's official documentation and several similar token unlock data platforms, finding no significant discrepancies between the previously recorded information and the publicly available documents at that time.Subsequently, RootData communicated further with the Aster official team and updated the on-site Aster token unlock data based on the latest confirmed information from the project team. Currently, some third-party token unlock data platforms have not yet synchronized this official document adjustment, making RootData one of the earlier platforms to complete the relevant data updates.This adjustment mainly involves two categories: Airdrop and Ecosystem & Community, with the specific changes as follows:1. Airdrop Category Adjustment: Split into "Founder's Airdrop" and "Governance Airdrop"Based on the latest confirmed information from Aster, RootData has re-split the original airdrop category into "Founder's Airdrop" and "Governance Airdrop."The previous official document indicated that after the Aster TGE, eligible participants would immediately receive 8.8% of the total allocation, with the remaining tokens in this category gradually released over the next 80 months, with specific release times potentially adjusted based on protocol governance.The latest official document adjustment states that the remaining ASTER tokens in this category will be reserved for airdrops, but the protocol governance body may adjust the relevant arrangements in the future.Therefore, RootData will no longer track the unlock data for the governance airdrop portion according to a fixed release cycle, and will instead dynamically update based on Aster's official announcements and governance decisions.2. Ecosystem & Community Category Adjustment: Split into Ecosystem & Community 1 and Ecosystem & Community 2Previously, the Aster Ecosystem & Community category (excluding the APX to ASTER conversion part) adopted a linear release model, planning to gradually unlock over 20 months. This model has been executed for 4 months (from October 2025 to January 2026), after which it will be adjusted to a reward distribution model based on staking mechanisms.According to Aster's current staking mechanism, the longer the user locks their tokens, the higher the loyalty reward APY they can receive. Since this allocation mechanism has shifted from a fixed linear release to a staking incentive model, RootData will no longer track the fixed unlock cycle for Ecosystem & Community 2 as originally planned, and will adjust based on the latest official announcements.It is reported that Aster completed its token TGE on September 17, 2025. Since its launch, Aster has made multiple adjustments to its token economic model, including extending the team token lock-up period by 12 months, adjusting the release method for ecosystem and community tokens, and redefining the governance arrangements for the remaining airdrop tokens.RootData stated that adjustments to the token economic model as the project develops and governance needs arise are common in the industry; the key is whether the project team can disclose relevant changes in a timely and transparent manner. RootData also encourages project teams to proactively submit token unlock plans and change information to help the community and users better understand token supply and release situations.

Cambridge Research: The United States hosts about 31% of Ethereum nodes, with over 1/3 of the nodes offline or affecting final confirmation

The latest research from the Cambridge Centre for Alternative Finance shows that approximately 31% of Ethereum node activity is located in the United States, with about 39% distributed in the EU region excluding the UK, indicating that the geographical distribution of Ethereum nodes is still relatively concentrated in Western countries. The research leader, Alexander Neumuller, stated that the current node distribution is not concentrated in a single country but primarily relies on a few cloud service providers, including Hetzner, Amazon AWS, and OVH.It is noteworthy that the Ethereum network does not require half of the validators to fail for issues to arise; when more than one-third of validators go offline simultaneously, the network may be unable to complete the finalization of block checkpoints. Neumuller pointed out that nodes and validators do not have a one-to-one correspondence; a single node may run multiple validators, making it currently impossible to accurately assess the actual impact of a specific node or service provider failure on the validation network. Additionally, the research reassessed the energy consumption situation after Ethereum's Merge. The data shows that Ethereum's current annual energy consumption is approximately 7.9 GWh, equivalent to about 1 megawatt of continuous power, which is only about 0.02% of the pre-Merge level, with energy consumption decreasing by approximately 99.98%. Currently, the proportion of sustainable energy used by the Ethereum network exceeds 56%, higher than the global average. The research also pointed out that the concentration of client software is another potential risk; if a dominant client has a vulnerability, it could affect a large number of network participants. The report was published by the Cambridge Centre for Alternative Finance, with support from the Ethereum Foundation.

1confirmation Founder: The next round of user growth in the crypto market may be driven by the tokenization of RWA

Nick Tomaino, founder of 1confirmation, stated on the X platform that bringing real-world assets (RWA) on-chain will become an important direction for driving the next phase of development in the cryptocurrency industry and is expected to lead to large-scale consumer adoption. The core value of bringing RWA on-chain lies in enabling global users to access asset classes that were previously difficult to obtain. "Global accessibility" has always been one of the most attractive features of the cryptocurrency industry and is also a key reason for the success of crypto assets like Bitcoin and Ethereum.Nick Tomaino believes that crypto assets that drive new behaviors and are built on concepts that go beyond mere monetary value will continue to exist in the long term. However, as the market gradually realizes that the cost of creating tokens is close to zero, the model of relying solely on token issuance to drive price increases is difficult to sustain. The growth cycle of many "speculative tokens" is coming to an end, and the market will enter a new growth phase driven by tokens backed by real assets. Currently, stablecoins have become the most mature case of RWA applications, and in the coming year, the on-chainization of assets such as stocks, commodities, government bonds, corporate bonds, and real estate is expected to accelerate further.Nick Tomaino mentioned that on-chain physical collectibles (such as sports cards and jerseys) could become one of the most worthwhile directions for building and investing in RWA today. As the speculative-driven token cycle gradually recedes, on-chain assets supported by real assets and practical use cases will be key to attracting the next batch of users into the cryptocurrency market.
