Infrastructure for Global Capital Markets to Be Built on Solana

The Solana dev community announced a series of technological upgrades that will transform the blockchain ecosystem into a full-fledged infrastructure for high-frequency institutional and retail trading.

A roadmap was unveiled for transforming the Solana blockchain ecosystem so that it can become a decentralized infrastructure for global capital markets. The key technological aspect is the implementation of the ACE (Application-Controlled Execution) architecture, which will give decentralized applications (dApps) control over the transaction execution order at the millisecond level.

The ACE architecture allows dApps to independently set rules for transaction execution and prioritization, eliminating risks of centralization and manipulation by validators, an essential feature for building highly liquid and transparent blockchain markets.

The first step in deploying the new architecture will be the launch of the Block Assembly Marketplace (BAM), scheduled for late July 2025. BAM will be implemented by the Jito Labs team. This system will provide:

• transaction privacy until execution;
• cryptographic proofs of execution order;
• the ability to set custom prioritization rules within a slot.

BAM is a high-performance modular transaction processing system operating based on Trusted Execution Environments (TEE).

Developers are already integrating BAM plugins implementing logic based on a Central Limit Order Book (CLOB). This will enable the creation of trading venues with guaranteed transparency and low latency, similar to centralized platforms.

Additionally, developers upgraded the TPU client and improved transaction processing via the QUIC protocol. Thanks to these improvements, the execution latency is zero slots in 95% of cases, meaning transactions are included in the correct slot almost instantly. These updates are expected to roll out soon.

Next steps for Solana ecosystem upgrades include:

1. In September 2025, deployment of a dedicated fiber-optic data transmission infrastructure called DoubleZero for the mainnet, aimed at reducing network latency to 100 ms and increasing validator throughput tenfold. This solution is already in testing with over 100 validators and 3% of staked assets on mainnet.
2. In early 2026, implementation of the new consensus protocol Alpenglow, which will reduce block finalization time to 150 milliseconds from the current 12.8 seconds. Together with Asynchronous Program Execution (APE), this will further reduce execution latency and boost mainnet performance.
3. In 2027, realization of the Multiple Concurrent Leaders (MCL) concept, allowing multiple validators to add transactions to blocks simultaneously, enhancing network resilience, reducing geographic latency, and enabling full ACE implementation at the protocol level.

According to these plans, the Solana ecosystem is moving from performance optimization toward a fundamental structural transformation, building a decentralized infrastructure suited for a broad range of institutional and retail market participants. The new roadmap represents not just technological improvements but the establishment of new standards for market blockchain infrastructure.

Previously, Dubai’s Virtual Asset Regulatory Authority (VARA) agreed on comprehensive cooperation with the Solana Foundation, while FinTech company Taurus integrated support for the Solana blockchain into its corporate custodial and RWA solutions to enhance efficiency and automate operational and financial processes.
