The Solana ecosystem has begun testing one of the largest upgrades in the network’s history. Anza developers confirmed the launch of Alpenglow in the validator test cluster—this is the first step before a possible rollout of the upgrade to the mainnet.
For Solana, this is more than just a technical update. It is a complete overhaul of the consensus mechanism, which should reduce transaction finalization time and improve network resilience under heavy load.
Solana Prepares to Abandon Part of Its Current Architecture
Currently, Solana uses a combination of Proof-of-History and TowerBFT. The first technology is responsible for cryptographic timestamp synchronization of transactions, while the second helps validators agree on the network state.
This architecture is what allowed Solana to achieve high speed and low fees. However, the network has repeatedly faced outages and instability during activity spikes.
Alpenglow is expected to solve some of these problems. The new consensus mechanism aims for faster block finalization and more stable validator performance.
Validators Are Already Testing the Upgrade
According to Anza, the new system is already running within the validator test infrastructure. Now, node operators can check how the upgrade behaves in real-world conditions.
This is especially important for Solana, because any change to consensus directly affects the stability of the entire network. An error at this level could lead to blockchain stoppage or loss of synchronization between validators.
Developers are calling Alpenglow the largest consensus change in the project’s history. Judging by the scale of the architectural changes, this description seems justified.
LayerZero Admits Its Own Mistake for the First Time
Alongside the news about Solana, the industry continues to discuss the aftermath of the $292 million Kelp DAO hack. After several weeks of mutual accusations, LayerZero unexpectedly changed its rhetoric and admitted its own responsibility for part of the problem.
The company stated that it made a mistake by allowing its transaction verification system to use a vulnerable configuration to protect high-value assets.
Previously, LayerZero claimed that the attack was caused by misconfiguration on the part of Kelp DAO. Now, the project has acknowledged that it did not control which assets its verification infrastructure was protecting.
The Problem Was in the Confirmation Model
The main vulnerability was related to the “1 of 1” configuration. In this scheme, confirmation of a transfer between blockchains required approval from only one verifying node.
In practice, this created a single point of failure. For infrastructure handling hundreds of millions of dollars, such a model turned out to be too risky.
Amid the growing number of attacks on bridges and cross-chain protocols, this case has reignited the discussion about the security of inter-network infrastructure.
Ronin Is Finally Moving Away From the Sidechain Model
Another major change is happening within Ronin—the blockchain that many still associate with the $625 million Axie Infinity hack.
The network has officially begun transitioning from an independent sidechain to Ethereum Layer 2. The migration started after a hard fork and is accompanied by a temporary network shutdown of about ten hours.
For the project, this is an attempt to strengthen security after one of the largest hacks in DeFi history.
Why Ronin Is Moving Closer to Ethereum
When Ronin launched a few years ago, the main goal was speed and low fees for gaming applications. At the time, an independent sidechain was the fastest solution.
But the 2022 attack exposed the weaknesses of such architecture. Layer 2 networks gain a closer connection to Ethereum and additional security from the base layer.
Now, Ronin is trying to maintain high performance while reducing the risk of repeating past problems.
Ethereum Launches Protection Against ‘Blind Signing’
The Ethereum Foundation, together with wallet developers, has introduced a new security system called Clear Signing.
Its goal is to solve one of the industry’s oldest problems: users often sign transactions without understanding what they are confirming.
Currently, many wallets display long sets of technical data that the average user cannot decipher. This is the basis for a significant portion of phishing attacks and thefts.
Clear Signing Should Make Transactions More Understandable
The new system will translate complex technical data into a human-readable description of actions.
Instead of a meaningless string of code, the user will see exactly what is happening: token transfer, granting contract permission, or wallet access.
After the Bybit hack and numerous attacks through fake websites, the issue of ‘blind signing’ has once again become one of the main problems for the Ethereum ecosystem.
Institutions Continue to Enter Blockchain
Amid technological upgrades, traditional financial companies continue to strengthen their presence in the crypto industry.
Charles Schwab has begun rolling out spot trading of Bitcoin and Ethereum for retail clients in the US. The company manages assets of about $12 trillion.
Meanwhile, JPMorgan is preparing its own tokenized money market fund on the Ethereum blockchain. Through the Kinexys infrastructure, users will be able to buy and redeem fund shares directly via blockchain.
Regulation Also Continues to Move Forward
The US Senate Committee has published an updated version of the CLARITY Act bill. The document is intended to define rules for regulating the crypto market and integrating digital assets into the US financial system.
Within the industry, particular attention is being paid to provisions on stablecoins, CFTC powers, and protection of DeFi protocol developers.
At the same time, the Senate has approved Kevin Warsh to the Federal Reserve Board of Governors. Now, a separate vote remains on his appointment as head of the Federal Reserve System, replacing Jerome Powell.
What’s Next?
Recent weeks show that the industry is entering a new phase of development. The market is no longer focused only on token prices—now, attention is shifting to infrastructure, security, and integration with traditional finance.
Solana is testing its largest consensus upgrade, Ethereum is trying to solve the signature security problem, and major banks continue to move financial products onto the blockchain.
Against this backdrop, competition between networks is gradually turning from a fee race into a battle for reliability, speed, and the ability to serve institutional capital.
