Solana 为超过三倍大的交易腾出空间

Core Points

The byte limit for Solana transactions has been raised to 4,096 bytes, compared with the previous limit of 1,232 bytes. The V1 format allows complex operations to be integrated into a single transaction. Traditional V0 and old wallet transactions can still be used normally. Large transactions may face higher priority fees.

Solana activates the txv1 function, significantly improving transaction data carrying capabilities.

On September 15, at the beginning of the 1035th Era (Epoch), Solana officially activated the txv1 function on the main network. This upgrade expands the maximum transaction size from 1,232 bytes to 4,096 bytes. The new restriction standards give applications more data space, allowing them to accommodate more instructions, signatures, or encrypted data in one operation without being limited by the capacity bottlenecks of earlier formats.

It should be noted that applications must proactively choose to access the V1 format to use this larger restriction. At the same time, Legacy (Traditional) and V0 transactions continue to operate normally as usual, ensuring backward compatibility of the network.

Technical boundary clarification: transaction size does not equal transfer amount

此次调整针对的是附加在交易上的数据规模，而非用户可发送的 SOL 数量。简单的转账操作包含的信息相对较少，主要包括发送方、接收方、金额、签名及基础指令。然而，更复杂的应用场景可能需要多个指令、长长的账户列表或在同一笔交易中完成多次审批。

Solana 具备并行处理无关交易的能力，这是其底层架构的核心优势之一。Transaction V1 并未改变这一模型，而是解决了单个交易因数据量过大而无法拆分的问题——在没有 V1 之前，若强行拆分，往往需要额外的签名、确认或由应用层进行复杂的协调。

V1 格式支持的三大典型应用场景

• 多步骤交易： 交易应用程序可能需要同时提交相互关联的指令。通过 V1，这些工作可以在单笔交易中一次性上链，无需应用层协调多次独立的确认过程。
• 企业级钱包审批： 企业钱包通常要求多名管理者对转账进行签字。在多签安排较大的情况下，签名及相关账户信息会占用大量空间，V1 格式为此提供了必要的扩展性。
• 隐私证明：零知识证明允许应用在不完全披露底层信息的情况下验证条件成立。这类证明的数据量往往较大，此前可能超出交易限制，现在可通过 V1 轻松处理。

Solana 基金会还指出，批量操作及某些链上签名方案等负载也可利用这种更大的格式。由于该更大格式仅通过 V1 提供，应用程序必须在代码中添加支持后方可使用。

用户与开发者的注意事项

对于钱包用户而言，此次变化主要在后台发生：

• Legacy 和 V0 交易仍受支持，用户无需迁移 SOL 或创建新地址。
• 保持钱包软件更新有助于在应用程序使用新格式时顺利签署 V1 交易。

应用团队则面临更多开发工作：

任何创建或读取 V1 交易的服务都必须支持新格式，包括遵循新的交易限制规则及解析 V1 交易数据。如果旧的交易日志读取器和索引器未进行更新，它们在遇到 V1 交易时可能会出现故障或误读数据。

容量增加可能伴随更高成本

Large transactions consume more verifier bandwidth than basic transfers. The Solana document states that during busy network hours, dispatchers may require large transactions to pay higher priority fees to ensure they are packaged into blocks.

V1 is designed to serve trading scenarios that truly require more space. For example, a single privacy certificate or multiple-approved treasury transfer can replace multiple confirmations with a single transaction; for basic transfers, the benefits of using a larger format are negligible.

Fees not only affect immediate costs to users, but are also an important part of verifier revenue. Transaction fees and preferred tips have risen recently as Internet activity has increased, but these incomes can change rapidly as demand fluctuates.

Macro Background: Evolution of the Solana Economic Model

The launch of Transaction V1 comes at a time of broader changes in the Solana economic system. V1 provides application builders with a way to embed more data in a single operation, while verifiers need to receive and process these larger message packets.

At the same time, the network is also preparing for a future transition to reduce SOL circulation. Previously, stakeholders voted for a faster deflation mechanism. Although this supply decision is independent of Transaction V1 itself, in the long run, it may make fee income, priority fees, and other activity-based income more important in the verifier's economic model.

Summary: Bringing new options to application design

Before the advent of V1, applications that exceeded the 1,232-byte limit had to spread their work across multiple independent transactions. The new format allows developers to merge some steps. In the end, users may experience fewer approval requests and fewer transaction failures due to the need to perform multiple actions simultaneously.
