邮票改进提案（SIP）

邮票改进提案流程为提议、审查和激活 Bitcoin Stamps 生态系统协议级别变更提供了结构化框架。每个 SIP 协调跨索引器的实现，以在整个生态系统中保持一致的行为。

什么是 SIP？

SIP（邮票改进提案）是影响协议共识的变更所必需的——这意味着所有索引器必须以相同方式实现变更，才能在整个生态系统中保持一致的行为。

SIP 需要用于：

• 新的 SRC-20 操作（条件转账、桥接、退款）
• 现有操作上的新字段（哈希锁、时间锁）
• 新的编码方法（二进制格式、P2WSH 结构）
• 跨链桥接协议

SIP 不需要用于不更改共识行为的仅索引器优化、API 功能或错误修复。

流程文档：SIP-0000 定义了完整的提案生命周期和审查流程。

Implementation Roadmap

Strategic phasing ensures each foundation is battle-tested before dependent features build upon it.

Phase 1FoundationWeeks 1-10

HTLC capabilities, binary encoding, and dual transaction parsing

SIP-0001SRC-20 Conditional Transfers (Hashlock/Timelock)3-4 weeks

SIP-0005Binary Transfer Format for SRC-202 weeks

SIP-0008Dual Transaction Parsing — Combined SRC-20 Transfer + Stamp Issuance2-3 weeks Soft dep: SIP-0005

Phase 2Core TradingWeeks 6-14

Native on-chain liquidity with AMM functionality

SIP-0006Native SRC-20 AMM (Automated Market Maker)4-6 weeks Soft dep: SIP-0005

Phase 3Cross-ChainWeeks 10-22

Bridge connectivity to EVM chains

SIP-0003SRC-20 Cross-Chain Bridge Specification6-8 weeks Soft dep: SIP-0001

Phase 4Wrapped Assets & BTC PoolsWeeks 18-28

Wrapped asset standard enabling Bitcoin-native liquidity pools

Includes future SIPs not yet formally drafted

Phase 5PrivacyWeeks independent

Stealth addresses to zero-knowledge shielded pools

Recommended Implementation Order

Priority	SIP	Effort	Hard Dependencies	Soft Dependencies
1	SIP-0001SRC-20 Conditional Transfers (Hashlock/Timelock)	3-4 weeks	None	—
2	SIP-0005Binary Transfer Format for SRC-20	2 weeks	None	—
3	SIP-0008Dual Transaction Parsing — Combined SRC-20 Transfer + Stamp Issuance	2-3 weeks	None	SIP-0005
4	SIP-0006Native SRC-20 AMM (Automated Market Maker)	4-6 weeks	None	SIP-0005
5	SIP-0003SRC-20 Cross-Chain Bridge Specification	6-8 weeks	None	SIP-0001
6	SIP-0004Shielded SRC-20 — Privacy Extension (Phased)	2-18 months	None	—

Gating Criteria Between Phases

Strategic checkpoints ensure stability before adding complexity:

Gate	Condition	Rationale
Phase 1 → Phase 2	SIP-0001 live for 2000+ blocks (~2 weeks)	HTLC must be battle-tested before AMM dependencies
Phase 2 → Phase 3	SIP-0006 Phase 1 stable for 1000+ blocks	AMM core proven before cross-chain integration
Phase 3 → Phase 4	SIP-0003 bridge operational, security audited	Bridge custody is high-risk — requires validation

Future Protocol Extensions

These extensions are planned but not yet formally drafted:

Future SIP	Purpose	Prerequisite
SIP-0007 (Wrapped Asset Standard)	wBTC/wUSDT mint/burn protocol, custody model	SIP-0003 bridge architecture
Concentrated Liquidity	Uniswap V3-style capital efficiency	SIP-0006 Phase 1 proven stable
Multi-hop Router	A→B→C swaps in single operation	Multiple active AMM pools
Governance	Protocol fee distribution, parameter changes	Ecosystem maturity

Indexer Coordination

SIPs that change consensus behavior require coordination across multiple indexers:

• stampchain (primary indexer): Must implement for activation
• OpenStamp: Should implement for ecosystem consistency
• Future indexers: Implementation encouraged but not blocking

For a SIP to reach Accepted status:

• stampchain team approves the specification
• At least one other indexer acknowledges the specification
• No unresolved security concerns remain

Activation blocks are coordinated with minimum 4 weeks lead time to allow all indexers to prepare.

参与其中

SIP 流程对所有社区成员开放：

1. 讨论 — 加入活跃 SIP 的 GitHub 问题对话
2. 提议 — 遵循 SIP-0000 格式创建新的协议提案
3. 审查 — 对规范提供技术反馈
4. 实现 — 为接受的提案构建索引器支持

SIP 流程有意保持轻量——足够的结构来协调索引器，而不会减慢创新速度。
