The Solana development team Anza posted on platform X, suggesting that Solana mainnet-beta validators urgently upgrade to version Agave 4.4.1, or they will be forked out of the network.This version applies a minimum loading data limit to the loader-v3 ProgramData account, and nodes that do not install the patch are scheduled to be forked out of the network at the 1079th epoch (around 21:30 Beijing time).

The Nasdaq-listed trading and investment platform eToro announced on November 4 that it has reached an agreement to acquire the Argentine comprehensive financial application LB Finanzas. The company stated that this acquisition will strengthen its presence in Latin America, with Argentina serving as a regional hub.LB Finanzas was founded in 2018 in Rosario and provides investment and account services within a single application for individuals and businesses, covering stocks, ETFs, crypto assets, and money market funds, as well as offering Argentine peso and US dollar accounts and payment solutions. The company has seen significant growth in user scale and trading volume, currently serving hundreds of thousands of users, regulated by the Argentine National Securities Commission and the Central Bank.eToro co-founder and CEO Yoni Assia stated: Both parties believe that everyone should have access to the tools and knowledge needed to grow wealth. By combining local expertise with eToro's global scale and products, we can advance faster and further in the region. LB Finanzas co-founder and CEO Camilo Cristia stated: For existing customers, current services will remain unchanged, and we will increase products and scale in the future. The transaction is subject to the completion of customary closing conditions and marks eToro's fourth acquisition in 2026; the company previously agreed to acquire the self-custody crypto wallet Zengo in April, acquired the Israeli crypto exchange Bit2C in May, and announced an agreement to acquire the US brokerage TradeZero in August.

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 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.

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.

The core development team of Solana, Anza developer Jacob Creech, stated that unlike some blockchains, Solana users do not need to urgently transfer assets due to AI-accelerated password cracking or quantum computing threats. He explained that Solana uses the Ed25519 signature algorithm, where the signing key is derived from a secret seed through hashing. Even if elliptic curve cryptography is cracked in the future, attackers cannot directly recover the original seed from it.Creech mentioned that theoretically, Solana could introduce a hash-based seed ownership proof through a network upgrade, allowing original holders to verify their identity and migrate to a more secure signing scheme. Anza has developed a related proof-of-concept prototype. He also emphasized that Solana is currently still secure and has a technical roadmap to address future cryptographic threats.

The Solana client development team Anza posted on X that Transaction V1 (SIMD-0385) has been launched on the mainnet.This version increases the maximum transaction size from 1,232 bytes to 4,096 bytes, allowing ZK proofs, large multi-signatures, BLS signatures, and previously required multiple transactions for confidential transfers to be included in a single atomic operation. V1 also moves resource requests such as computation unit limits, priority fees, account data loading size, and heap size into the transaction header, rather than submitting them through computation budget instructions.

Anza announced that the second phase of the Solana account rent reduction proposal SIMD-0437 has been launched on the mainnet beta. In epoch 1033, the per-byte parameter used to calculate the minimum balance for rent-exempt accounts has been reduced from 6333 lamports to 5080 lamports, a cumulative decrease of about 27% from the initial level, lowering the SOL balance required to maintain rent-exempt status.Anza also shared instructions for reclaiming excess SOL: users with the appropriate permissions can use the WithdrawExcessLamports instruction to withdraw SOL from token accounts, token mint accounts, etc., that exceed the minimum balance for rent exemption, without needing to close the accounts, and it does not affect the token balance. There is no fixed timeline for subsequent phases; the third phase will only be activated after confirming that the on-chain status growth is within a safe range; adjustments can be made in reverse through SIMD-0438 if necessary.

Anza stated that the reduction in Solana token rent has gone live on the mainnet Beta, and proposal SIMD-0437 Step 1 has been activated at epoch 1028.This step reduces the required lamports per byte from 6960 to 6333; subsequent functionality gates will be activated after checking the growth status at the current rent level, ultimately reducing to 696 gradually.

The Solana core client development team Anza announced that it is gradually removing floating-point operations from the Solana core protocol. The first layer, SIMD-0391, was activated in epoch 1026 of the mainnet Beta, replacing floating-point operations in the Stake Program and validator client’s warm-up and cool-down logic with fixed-point operations.The second layer, SIMD-0607, has been proposed and is under review, targeting the runtime itself to remove floating-point operations in the inflation rewards and rent calculation paths. Anza stated that floating-point operations can produce different rounding results on different hardware, validator clients, and compilers, which may lead to consensus divergence and network activity risks. These two improvements eliminate that risk by standardizing fixed-point operations. Further work will continue to address floating-point operations in other paths.

The core development team of Solana, Anza, announced that the Solana testnet has enabled the first phase of the SIMD-0437 proposal, and the account rent reduction mechanism has begun testing. This proposal includes a total of 5 functional gates, with only the first functional gate currently activated, and all adjustments have not yet been completed and deployed to the mainnet.Once all 5 phases are completed, the storage cost parameter lamports_per_byte for Solana will be reduced from 6960 to 696, resulting in an overall reduction of 90%. For example, in the case of token accounts, the deposit required to maintain an account in a rent-exempt state is expected to decrease from approximately $0.16 to $0.016, thereby lowering the costs of account creation and application deployment.

The Governor of the Bank of Tanzania, Emmanuel Tutuba, stated that the bank is completing the formulation of regulatory laws and regulations for digital assets, covering virtual assets, cryptocurrencies, and stablecoins, to enhance regulation and supervision.Emmanuel Tutuba mentioned that many young people are investing in related fields, and the central bank has received complaints from individuals who have incurred losses in cryptocurrency-related transactions. The relevant rules will be used to protect Tanzanian investors. He stated that the new regulations will also address the risks of money laundering, terrorist financing, and other illegal activities related to virtual assets, ensuring that entities involved in related activities operate according to the guidelines that will be released soon.

The Solana development company Anza announced that it has officially recommended the mainnet validators upgrade to Agave 4. This upgrade introduces XDP for Turbine, QUIC-only TPU data access, a faster replay stage, and several SIMD features that will be activated during this cycle.Anza stated that production environment tests on large mainnet validators showed that XDP has reduced the Turbine retransmission delay from about 600 ms to approximately 0.8 ms, providing critical performance headroom for Solana's push towards 100 million CU blocks. Additionally, Agave 4 has completely removed UDP transaction access, making QUIC the only transaction submission method; PoH entry verification and Ed25519 signature verification have also been removed from the critical path and processed asynchronously to enhance replay stage performance.This round of upgrades will also gradually enable several SIMD features, including p-token (an SPL Token alternative that can free up about 13% of block capacity), Stake Program v5, SBPFv3 support, pre-funded account creation, and BLS12-381 syscall, among others.

According to market news, the Solana core development team Anza has launched the Constellation protocol, a multi-concurrent proposer protocol that shortens Solana's block cycle to 50 milliseconds, making it the fastest blockchain in terms of economic rhythm at the protocol level.This protocol replaces the single leader model, eliminating exclusive control over transaction inclusion and ordering through concurrent proposers, enforcing fairness at the protocol level without relying on trusted third parties or modifying clients, while the validator economic model remains largely unchanged.

Brennan Watt, Vice President of Core Engineering at Solana research and development company Anza, stated at the Solana Breakpoint conference that the proposal SIMD-0389 could reduce the rent for Solana account creation by 10 times, with the potential for a 100 times reduction.According to Anza's analysis of the security slowdown mechanism, this change was discussed at the recent SolanaConf and could release broader adoption by reclaiming hundreds of millions of dormant SOL while maintaining network security.

Max Resnick, the chief economist of Solana research and development company Anza, stated at the Solana Breakpoint conference, "We reached 100,000 TPS in May. Not on the testnet, not in the white paper, but in the official launch. The market structure is also evolving in real-time: proprietary market makers are tightening the spreads, and now the trading volume of SOL-USD is three times that of Binance, with competition becoming extremely fierce, and the order book is getting tighter and deeper every day."

ChainCatcher news, according to Blockworks, Anza has proposed two proposals to implement a slashing mechanism in the network, primarily targeting the so-called "duplicate blocks" to penalize validators, which refers to the situation where the same block is created twice. Anza has not yet decided on the specific economic details of the penalty mechanism, but the author of SIMD suggested destroying (or functionally abolishing) the staked tokens that are penalized.Anza's Ashwin Sekar also proposed a parabolic penalty curve: if 5% of a validator's staked tokens are in violation, then 1% of their staked tokens will be destroyed; if 33% of the staked tokens are in violation, then all staked tokens will be penalized. Sekar explained in a validator discussion session that Ethereum's penalty curve is linear. Sekar also stated that the penalty proposal is still in its early stages, and such updates are not expected to be released until the summer of 2025 at the earliest.

ChainCatcher news, Ethereum ecosystem developer Max Resnick announced that he has left his job at Consensys to join Solana development company Anza.Resnick plans to write specifications for the Solana protocol as much as possible in the initial 100 days, prioritizing the fee markets and consensus implementations that he believes will have the greatest impact.Resnick stated that he will continue to collaborate with the Consensys team as a research advisor while focusing on his new role.
