Solana's Internet History: Major Events and Key Milestones

Solana 网络发展史：从启动到重大区块链里程碑

Solana 网络的发展史宛如一场从未停止的压力测试。该链始于 2017 年的研究构想，于 2020 年正式上线，此后经历了宕机、市场崩盘和创纪录的流量冲击。人们关注 Solana 的历史，是因为过去塑造了今天的声誉。如今，该网络因速度而备受赞誉；而在不久前，它却因频繁离线而受到批评。

Solana 是如何起步的？从白皮书到主网

2017 年，创始人 Anatoly Yakovenko 发布了 Solana 白皮书。其核心理念是“历史证明”（Proof of History），这是一种密码学时钟机制，使计算机能够在无需持续通信的情况下对事件顺序达成共识。这些参与计算的节点被称为验证者（Validators），它们负责检查交易、生成区块并维持区块链的运行。共享时钟意味着它们可以更高效地协同工作。

主网 Beta 版于 2020 年 3 月上线。Solana 网络的早期阶段充满了宏大的承诺，但缺乏实际运行记录。SOL 是该网络的原生代币，用于支付交易费用，持有者可以通过将代币委托给验证者来进行质押。官方文档对此有详细说明。

哪些事件定义了 Solana 网络发展时间线？

The following table lists the main turning points. For incidents for which exact details are not provided on the official page, only a general description is provided here:

• 2017: The white paper introduces "historical proof". Established the clock concept behind the design.
• March 2020: Main network Beta launched. Public networks are open to users and applications.
• 2021 to 2023: Multiple outages occurred during peak traffic periods. Promote the introduction of new traffic rules and the redesign of the scheduler.
• February 2024: announced the start of achieving 100% uptime. This is a statement by the project party and has not been independently verified.
• 2025: The Foundation is committed to reducing the pledge share of a single provider from 38% to less than 30%. Designed to reduce the risks posed by a single provider.
• August 12, 2026: Routing failure caused nearly 29% of pledges to go offline. Despite this situation, the block continues to produce.
• September 18, 2026:Transaction V1 entered the main network. Making larger-scale transactions possible.
• Second half of 2026 (planned):Alpenglow main network release target. Designed to achieve final certainty of 150 milliseconds; still a planned plan.

The model is simple: Early years brought stress and stagnation, while recent years brought upgrades and fewer failures.

Why did Solana experience downtime early on?

The network review report released by the foundation admitted that the network experienced downtime in its early days. Robot-driven exchanges expose weaknesses in validators when processing incoming traffic. Huge demand exacerbates this problem. When too many transactions arrive at the same time, it is difficult for the verifier to cope, causing the network to slow down or stop.

There have been two significant restoration measures in the history of Solana. First, the connection capacity of the validator is increased. Secondly, pledge volume-based quality of service (SWQoS) is introduced. The system prioritizes traffic sent by verifiers with high pledge volumes, making spam transactions more difficult. It was later discovered that the scheduler was flawed, and the old system rewarded the behavior of sending the same transaction repeatedly. A complete redesign eliminated the meaning of duplicate transactions.

What has changed after February 2024?

The project party claims that Solana has maintained 100% normal operating time since February 2024. This is a statement by the project party and should be viewed with caution. Reliability is particularly important under high traffic. A quiet chain may seem stable, but a busy chain must prove its strength.

The incident of August 12, 2026 became the biggest test in recent times. Routing failures at the largest infrastructure provider have caused nearly 29% of network pledges to go offline. The pledge amount refers to the amount of SOL entrusted to the verifier, which gives the verifier voting weight. Despite this failure, blocks continue to be produced and transactions are still being implemented. The provider recovered after more than 30 minutes. In 2025, the foundation noticed that the provider hosted 38% of the pledge volume and worked hard to reduce it to below 30% before the failure occurred. DevNet lost about three-quarters of its pledges and recovered without a coordinated restart.

This is by far the strongest chapter in Solana's history, because the failure stems from infrastructure rather than code issues.

What upgrades are shaping Solana today?

Recent official pages show that the network focuses on speed and cost. The main contents include:

• Faster slots: Slots are a short window for the verifier to propose blocks. The target time is being reduced from 400 milliseconds to 250 milliseconds, and the target for the next discussion is 200 milliseconds.
• Cheaper storage: The foundation said that on-chain data storage rents have been cut by 90%.
• Bigger transaction: According to the change log on September 18, 2026, Transaction V1 has entered the main network.
• Alpenglow：The goal of this consensus upgrade is to achieve 150 milliseconds of final certainty (the point at which transactions are irreversible). It is said that the main network release will take place later this year, so it is still within the scope of the plan.
• Throughput: According to Solana's own data, the network achieved its first breakthrough of 5,000 sustainable user transactions per second.

As the changes are gradually rolled out, the slot times cited on the official page vary slightly. Exact current data should be consulted on the official website.

How big is the Solana ecosystem?

The foundation said that $17.5 billion worth of stablecoins and more than $4 billion of real-world assets (RWAs) are now running on Solana. Real-world assets are tokenized versions of assets such as funds or bonds. These data are reported by the project party. Its published list of partners includes Western Union, Franklin Templeton, MoneyGram, SoFi and BlackRock. The names on the list do not represent deep adoption, so details are crucial.

Apps and teams can be viewed on the official ecosystem page. Safety is also of great concern. Earlier this year, the foundation and security research partners launched the STRIDE program to provide independent review and public discovery of the DeFi protocol. DeFi (decentralized finance) refers to lending and transaction applications that run on smart contracts rather than traditional banks.

What are the residual risks faced by Solana and its holders?

Solana's history shows progress, but does not eliminate risks. Readers should weigh the following points:

• Downtime records: Early long periods of stagnation are still part of history. The current uptime record is declared by the project party and may be interrupted.
• Pledge concentration: In 2025, one provider holds 38% of the pledge volume. Even if it drops below 30%, a single provider still has considerable influence.
• Upgrade latency: Alpenglow and 200 msec slots are scheduled. The timetable may be delayed.
• Application-level vulnerability: Network uptime does not protect individual DeFi protocols from hackers.
• Price Volatility: SOL prices fluctuate violently and a long history cannot predict future returns. Listings vary on different platforms, so liquidity on each exchange is crucial.

Expert analysis: What does the timeline mean?

A prominent lesson in Solana's history is that every failure yields a specific fix, not just a patch. SWQoS solves the robot spam problem, the scheduler is redesigned to solve the duplicate transaction problem, and reducing pledge concentration responds to provider risk. This is an analyst's opinion, not a confirmation. Independent verification of uptime and decentralization will still strengthen this argument.
