Infrastructure for International Capital Markets to Be Developed on Solana

The Solana developer community has revealed a series of technological enhancements aimed at evolving the blockchain ecosystem into a comprehensive infrastructure for high-frequency trading, catering to both institutional and retail participants.

A roadmap has been introduced to transform the Solana blockchain ecosystem into a decentralized framework for global capital markets. A pivotal technological component is the adoption of the ACE (Application-Controlled Execution) architecture, which will empower decentralized applications (dApps) to manage the order of transaction execution at the millisecond level.

The ACE architecture enables dApps to autonomously establish rules for transaction execution and prioritization, thereby mitigating risks associated with centralization and manipulation by validators, a crucial aspect for developing highly liquid and transparent blockchain markets.

The initial phase of implementing the new architecture will involve the launch of the Block Assembly Marketplace (BAM), set for late July 2025. This initiative will be executed by the Jito Labs team and will offer:

• transaction confidentiality until execution;
• cryptographic verification of execution order;
• the capability to define custom prioritization rules within a slot.

BAM is a high-performance modular transaction processing system that operates utilizing Trusted Execution Environments (TEE).

Developers are currently integrating BAM plugins that incorporate logic based on a Central Limit Order Book (CLOB). This will facilitate the establishment of trading venues that guarantee transparency and low latency, akin to centralized platforms.

Moreover, developers have enhanced the TPU client and refined transaction processing through the QUIC protocol. As a result of these advancements, execution latency is zero slots in 95% of instances, indicating that transactions are included in the appropriate slot almost instantaneously. These updates are anticipated to be deployed shortly.

Future steps for upgrades within the Solana ecosystem include:

1. In September 2025, the rollout of a dedicated fiber-optic data transmission infrastructure named DoubleZero for the mainnet, designed to decrease network latency to 100 ms and enhance validator throughput by ten times. This solution is currently undergoing testing with over 100 validators and 3% of staked assets on the mainnet.
2. In early 2026, the introduction of the new consensus protocol Alpenglow, which will shorten block finalization time to 150 milliseconds from the existing 12.8 seconds. Alongside Asynchronous Program Execution (APE), this will further diminish execution latency and improve mainnet performance.
3. In 2027, the realization of the Multiple Concurrent Leaders (MCL) concept, which will permit multiple validators to add transactions to blocks simultaneously, thereby improving network resilience, minimizing geographic latency, and enabling full ACE implementation at the protocol level.

According to these plans, the Solana ecosystem is transitioning from performance enhancement to a fundamental structural overhaul, establishing a decentralized infrastructure suitable for a wide array of institutional and retail market participants. The new roadmap signifies not only technological advancements but also the establishment of new benchmarks for market blockchain infrastructure.

Previously, Dubai’s Virtual Asset Regulatory Authority (VARA) reached an agreement for extensive collaboration with the Solana Foundation, while FinTech firm Taurus integrated support for the Solana blockchain into its corporate custodial and RWA solutions to improve efficiency and automate operational and financial processes.
