交易

交易输出排序

交易中的输出总是按照以下规则排序：

• 首先根据它们的值排序，最小的在最前面（以整个 satoshis 为单位，注意对于 HTLC 输出，必须忽略 millisatoshi 部分）
• 其次是 scriptpubkey，按字典顺序比较公共长度的前缀，就像用 memcmp 一样，然后选择较短的脚本（如果它们的长度不同），
• 最后，对于 HTLC 输出，按 cltv_expiry 升序排列。

理由

两个具有相同 amount（从 amount_msat 四舍五入）和 payment_hash 的 offered HTLC 将具有相同的输出，即使它们的 cltv_expiry 不同。这只是因为相同的排序用于发送 htlc_signatures，并且 HTLC 交易本身是不同的，因此两个节点必须就这种情况的规范排序达成一致。

Segwit 的使用

这里使用的大多数交易输出都是 pay-to-witness-script-hash^BIP141 (P2WSH) 输出：P2SH 的 Segwit 版本。要花费这些输出，见证堆栈上的最后一项必须是用于生成正在花费的 P2WSH 输出的实际脚本。为了简洁起见，本文档的其余部分省略了最后一项。

根据 MINIMALIF 标准规则^MINIMALIF，<> 指定一个空向量以符合要求。

Funding Transaction Output

• funding output 脚本是一个 P2WSH，内容为:

2 <pubkey1> <pubkey2> 2 OP_CHECKMULTISIG

• 其中 pubkey1 是两个压缩格式的 funding_pubkey 中按字典顺序较小的那个，pubkey2 是两个中按字典顺序较大的那个。

Commitment Transaction

• version: 2
• locktime: 高 8 位为 0x20，低 24 位是模糊 commitment number 的低 24 位
• txin count: 1
  • txin[0] outpoint: 来自 funding_created 消息的 txid 和 output_index
  • txin[0] sequence: 高 8 位为 0x80，低 24 位是模糊 commitment number 的高 24 位
  • txin[0] script bytes: 0
  • txin[0] witness: 0 <signature_for_pubkey1> <signature_for_pubkey2>

48 位的 commitment number 通过与以下内容的低 48 位进行 XOR 运算来模糊处理：

SHA256(open_channel 中的 payment_basepoint || accept_channel 中的 payment_basepoint)

这模糊了单方面关闭时在通道上做出的 commitments 的数量，但仍然为两个节点（它们知道 payment_basepoint）提供了一个有用的索引，可以快速找到撤销的 commitment transaction。

Commitment Transaction Outputs

为了在撤销 commitment transaction 的情况下提供 penalty transactions 的机会，所有将资金返回给 commitment transaction 的所有者（又名“本地节点”）的输出都必须延迟 to_self_delay 个区块。对于 HTLC，此延迟在第二阶段 HTLC transaction 中完成（对于本地节点接受的 HTLC 为 HTLC-success，对于本地节点提供的 HTLC 为 HTLC-timeout）。

HTLC 输出采用单独的transaction阶段的原因是，即使 HTLC 位于 to_self_delay 延迟期内，HTLC 也可以超时或被兑现。否则，HTLC 上所需的最小超时将因该延迟而延长，从而导致遍历网络的 HTLC 的超时时间更长。

每个输出的金额必须向下舍入到整个 satoshis。如果此金额减去 HTLC transaction 的费用后，小于 commitment transaction 的所有者设置的 dust_limit_satoshis，则不得生成该输出（因此资金会添加到费用中）。

to_local 输出

此输出将资金返回给此 commitment transaction 的所有者，因此必须使用 OP_CHECKSEQUENCEVERIFY 进行时间锁定。如果另一方知道撤销私钥，则可以立即声明。该输出是 version-0 P2WSH，带有见证脚本：

OP_IF
    # Penalty transaction
    <revocationpubkey>
OP_ELSE
    `to_self_delay`
    OP_CHECKSEQUENCEVERIFY
    OP_DROP
    <local_delayedpubkey>
OP_ENDIF
OP_CHECKSIG

该输出由 nSequence 字段设置为 to_self_delay（仅在该持续时间过去后才有效）的输入和见证花费：

<local_delayedsig> <>

如果发布了撤销的 commitment transaction，则另一方可以使用以下见证立即花费此输出：

<revocation_sig> 1

to_remote 输出

如果 option_anchors 适用于 commitment transaction，则 to_remote 输出会被一个区块的 csv 锁锁定。

<remotepubkey> OP_CHECKSIGVERIFY 1 OP_CHECKSEQUENCEVERIFY

该输出由 nSequence 字段设置为 1 的输入和见证所花费：

<remote_sig>

否则，此输出是一个简单的指向 remotepubkey 的 P2WPKH。注意：remote 的 commitment transaction 使用你的 localpubkey 作为他们给你自己的 to_remote 输出。

to_local_anchor 和 to_remote_anchor 输出 (option_anchors)

此输出可以分别由本地和远端节点花费，以激励挖矿 transaction，使用 child-pays-for-parent。除非没有 htlc 并且其中一方的 commitment 输出低于 dust limit，否则总是添加两个 anchor 输出。在那种情况下，仅为实现的 commitment 输出添加一个 anchor。如果发起者在打开后立即关闭（没有 to_remote 输出），通常会发生这种情况。

<local_funding_pubkey/remote_funding_pubkey> OP_CHECKSIG OP_IFDUP
OP_NOTIF
    OP_16 OP_CHECKSEQUENCEVERIFY
OP_ENDIF

每一方都有自己的 anchor 输出，锁定到他们的 funding key。这是为了防止恶意节点将具有低费用密度的子 transaction 附加到 anchor，从而阻止受害者及时确认 commit tx。Bitcoin core 0.19 中的一项更改支持这种防御：https://github.com/bitcoin/bitcoin/pull/15681。这也是 commit tx 上的每个非 anchor 输出都锁定 CSV 的原因。

为了防止 utxo 集合污染，任何未花费的 anchor 都可以在 commitment tx 确认后由任何人花费。这也是将 anchor 输出锁定到 funding key 的原因。第三方可以观察到这个 key 并重构花费脚本，即使 commitment 输出都不会被花费。这确实假设在某个时刻，费用市场下降到一个可以经济地清除 anchors 的水平。

输出的金额固定为 330 sats，这是 P2WSH 的默认 dust limit。

花费输出需要以下见证：

<local_sig/remote_sig>

16 个区块后，任何人都可以使用以下见证清除 anchor：

<>

Offered HTLC 输出

此输出在 HTLC-timeout 之后将资金发送到 HTLC-timeout transaction，或者使用 payment preimage 或撤销 key 将资金发送到远端节点。该输出是 P2WSH，带有见证脚本（没有 option_anchors）：

# 使用撤销 key 发送到远端节点
OP_DUP OP_HASH160 <RIPEMD160(SHA256(revocationpubkey))> OP_EQUAL
OP_IF
    OP_CHECKSIG
OP_ELSE
    <remote_htlcpubkey> OP_SWAP OP_SIZE 32 OP_EQUAL
    OP_NOTIF
        # 通过 HTLC-timeout transaction（时间锁定）发送到本地节点。
        OP_DROP 2 OP_SWAP <local_htlcpubkey> 2 OP_CHECKMULTISIG
    OP_ELSE
        # 使用 preimage 发送到远端节点。
        OP_HASH160 <RIPEMD160(payment_hash)> OP_EQUALVERIFY
        OP_CHECKSIG
    OP_ENDIF
OP_ENDIF

或者，使用 option_anchors：

# 使用撤销 key 发送到远端节点
OP_DUP OP_HASH160 <RIPEMD160(SHA256(revocationpubkey))> OP_EQUAL
OP_IF
    OP_CHECKSIG
OP_ELSE
    <remote_htlcpubkey> OP_SWAP OP_SIZE 32 OP_EQUAL
    OP_NOTIF
        # 通过 HTLC-timeout transaction（时间锁定）发送到本地节点。
        OP_DROP 2 OP_SWAP <local_htlcpubkey> 2 OP_CHECKMULTISIG
    OP_ELSE
        # 使用 preimage 发送到远端节点。
        OP_HASH160 <RIPEMD160(payment_hash)> OP_EQUALVERIFY
        OP_CHECKSIG
    OP_ENDIF
    1 OP_CHECKSEQUENCEVERIFY OP_DROP
OP_ENDIF

远端节点可以使用以下见证兑换 HTLC：

<remotehtlcsig> <payment_preimage>

请注意，如果 option_anchors 适用，则花费输入的 nSequence 字段必须为 1。

如果发布了撤销的 commitment transaction，则远端节点可以使用以下见证立即花费此输出：

<revocation_sig> <revocationpubkey>

发送节点可以使用 HTLC-timeout transaction 在 HTLC 过期后使其超时，如下所示。这是本地节点使 HTLC 超时的唯一方法，并且此分支需要 <remotehtlcsig>，这确保了本地节点不能过早地使 HTLC 超时，因为 HTLC-timeout transaction 将 cltv_expiry 指定为其指定的 locktime。本地节点还必须等待 to_self_delay 才能访问这些资金，从而允许远端节点在 transaction 被撤销的情况下申领这些资金。

Received HTLC 输出

此输出在 HTLC-timeout 之后或使用撤销 key 将资金发送到远端节点，或者通过成功的付款 preimage 发送到 HTLC-success transaction。该输出是 P2WSH，带有见证脚本（没有 option_anchors）：

# 使用撤销 key 发送到远端节点
OP_DUP OP_HASH160 <RIPEMD160(SHA256(revocationpubkey))> OP_EQUAL
OP_IF
    OP_CHECKSIG
OP_ELSE
    <remote_htlcpubkey> OP_SWAP OP_SIZE 32 OP_EQUAL
    OP_IF
        # 通过 HTLC-success transaction 发送到本地节点。
        OP_HASH160 <RIPEMD160(payment_hash)> OP_EQUALVERIFY
        2 OP_SWAP <local_htlcpubkey> 2 OP_CHECKMULTISIG
    OP_ELSE
        # 超时后发送到远端节点。
        OP_DROP <cltv_expiry> OP_CHECKLOCKTIMEVERIFY OP_DROP
        OP_CHECKSIG
    OP_ENDIF
OP_ENDIF

或者，使用 option_anchors：

# 使用撤销 key 发送到远端节点
OP_DUP OP_HASH160 <RIPEMD160(SHA256(revocationpubkey))> OP_EQUAL
OP_IF
    OP_CHECKSIG
OP_ELSE
    <remote_htlcpubkey> OP_SWAP OP_SIZE 32 OP_EQUAL
    OP_IF
        # 通过 HTLC-success transaction 发送到本地节点。
        OP_HASH160 <RIPEMD160(payment_hash)> OP_EQUALVERIFY
        2 OP_SWAP <local_htlcpubkey> 2 OP_CHECKMULTISIG
    OP_ELSE
        # 超时后发送到远端节点。
        OP_DROP <cltv_expiry> OP_CHECKLOCKTIMEVERIFY OP_DROP
        OP_CHECKSIG
    OP_ENDIF
    1 OP_CHECKSEQUENCEVERIFY OP_DROP
OP_ENDIF

要使 HTLC 超时，远端节点使用以下见证花费它：

<remotehtlcsig> <>

请注意，如果 option_anchors 适用，则花费输入的 nSequence 字段必须为 1。

如果发布了撤销的 commitment transaction，则远端节点可以使用以下见证立即花费此输出：

<revocation_sig> <revocationpubkey>

要兑换 HTLC，可以使用 HTLC-success transaction，如下详述。这是本地节点花费 HTLC 的唯一方式，因为此分支需要 <remotehtlcsig>，这确保了本地节点必须等待 to_self_delay 才能访问这些资金，从而允许远端节点在 transaction 被撤销的情况下申领这些资金。

Trimmed Outputs

每个节点都指定一个 dust_limit_satoshis，低于该值不应产生输出；这些未产生的输出被称为“trimmed”。trimmed output 被认为太小，不值得创建，而是添加到 commitment transaction 费用中。对于 HTLC，需要考虑到第二阶段的 HTLC transaction 也可能低于该限制。

要求

基本费用和 anchor 输出值：

• 在确定 commitment transaction 输出之前：
  • 必须从 to_local 或 to_remote 输出中扣除，如 费用计算 中所述。

Commitment transaction:

• 如果 commitment transaction to_local 输出的金额将小于 transaction 所有者设置的 dust_limit_satoshis：
  • 不得包含该输出。
• 否则：
  • 必须按照 to_local 输出 中指定的生成。
• 如果 commitment transaction to_remote 输出的金额将小于 transaction 所有者设置的 dust_limit_satoshis：
  • 不得包含该输出。
• 否则：
  • 必须按照 to_remote 输出 中指定的生成。
• 对于每个 offered HTLC：
  • 如果 HTLC 金额减去 HTLC-timeout 费用后将小于 transaction 所有者设置的 dust_limit_satoshis：
    • 不得包含该输出。
  • 否则：
    • 必须按照 Offered HTLC 输出 中指定的生成。
• 对于每个 received HTLC：
  • 如果 HTLC 金额减去 HTLC-success 费用后将小于 transaction 所有者设置的 dust_limit_satoshis：
    • 不得包含该输出。
  • 否则：
    • 必须按照 Received HTLC 输出 中指定的生成。

HTLC-Timeout 和 HTLC-Success Transactions

这些 HTLC transactions 几乎相同，除了 HTLC-timeout transaction 是时间锁定的。有效的 penalty transaction 都可以花费 HTLC-timeout/HTLC-success transaction。

• version: 2
• locktime: HTLC-success 为 0，HTLC-timeout 为 cltv_expiry
• txin count: 1
  • txin[0] outpoint: HTLC transaction 的 commitment transaction 的 txid 和匹配的 HTLC 输出的 output_index
  • txin[0] sequence: 0（对于 option_anchors 设置为 1）
  • txin[0] script bytes: 0
  • txin[0] witness stack: HTLC-success 为 0 <remotehtlcsig> <localhtlcsig> <payment_preimage>，HTLC-timeout 为 0 <remotehtlcsig> <localhtlcsig> <>
• txout count: 1
  • txout[0] amount: HTLC amount_msat 除以 1000（向下舍入）减去 satoshis 的费用（参见 费用计算）
  • txout[0] script: version-0 P2WSH，见证脚本如下所示
• 如果 option_anchors 适用于此 commitment transaction，则使用 SIGHASH_SINGLE|SIGHASH_ANYONECANPAY，如 BOLT #5 中所述。

输出的见证脚本为：

OP_IF
    # Penalty transaction
    <revocationpubkey>
OP_ELSE
    `to_self_delay`
    OP_CHECKSEQUENCEVERIFY
    OP_DROP
    <local_delayedpubkey>
OP_ENDIF
OP_CHECKSIG

要通过 penalty 花费此费用，远端节点使用见证堆栈 <revocationsig> 1，并且要收集输出，本地节点使用带有 nSequence to_self_delay 的输入和见证堆栈 <local_delayedsig> 0。

Closing Transaction

请注意，每个节点都有两种可能的变体。

• version: 2
• locktime: 0
• txin count: 1
  • txin[0] outpoint: 来自 funding_created 消息的 txid 和 output_index
  • txin[0] sequence: 0xFFFFFFFF
  • txin[0] script bytes: 0
  • txin[0] witness: 0 <signature_for_pubkey1> <signature_for_pubkey2>
• txout count: 1 或 2
  • txout amount: 支付给一个节点的最终余额（减去来自 closing_signed 的 fee_satoshis，如果此节点资助了通道）
  • txout script: 如该节点的 shutdown 消息中的 scriptpubkey 中指定的那样

要求

提供签名的每个节点：

• 必须将每个输出向下舍入到整个 satoshis。
• 必须从支付给资助者的输出中减去 fee_satoshis 给出的费用。
• 必须删除低于其自身 dust_limit_satoshis 的任何输出。
• 可以消除自己的输出。

理由

如果一个节点认为另一个节点的输出太小而无法在 Bitcoin 网络上传播（又名“dust”），而另一个节点反而认为该输出太有价值而无法丢弃，则可能在关闭时出现无法弥补的差异。这就是为什么每一方都使用自己的 dust_limit_satoshis，如果他们对 closing transaciton 的外观存在分歧，则结果可能是签名验证失败。

但是，如果一方选择消除自己的输出，则另一方没有理由未能通过 closing 协议；因此，明确允许这样做。签名指示使用了哪个变体。

如果 funding amount 大于 dust_limit_satoshis 的两倍，则将至少有一个输出。

费用

费用计算

commitment transactions 和 HTLC transactions 的费用计算均基于当前的 feerate_per_kw 和 transaction 的预期权重。

实际权重和预期权重因多种原因而异：

• Bitcoin 使用 DER 编码的签名，其大小各不相同。
• Bitcoin 还使用可变长度整数，因此大量输出将需要 3 个字节来编码，而不是 1 个字节。
• to_remote 输出可能低于 dust limit。
• 提取费用后，to_local 输出可能低于 dust limit。

因此，使用了一个简化的预期权重公式，该公式假定：

• 签名长度为 73 字节（最大长度）。
• 输出数量很少（因此计数它们需要 1 个字节）。
• 始终存在 to_local 输出和 to_remote 输出。
• （如果 option_anchors）始终存在 to_local_anchor 和 to_remote_anchor 输出。

这产生了以下预期权重（附录 A 中计算的详细信息）：

Commitment weight (没有 option_anchors):   724 + 172 * 未 trimmed-htlc-outputs 的数量
Commitment weight (option_anchors):     1124 + 172 * 未 trimmed-htlc-outputs 的数量
HTLC-timeout weight (没有 option_anchors): 663
HTLC-timeout weight (option_anchors): 666
HTLC-success weight (没有 option_anchors): 703
HTLC-success weight (option_anchors): 706

请注意以下要求中对 commitment transaction 的“基本费用”的引用，这是 funder 支付的费用。由于舍入和 trimmed outputs，实际费用可能高于此处计算的金额。

要求

HTLC-timeout transaction 的费用：

• 如果 option_anchors 适用：
  1. 必须为 0。
• 否则，必须计算以匹配：
  1. 将 feerate_per_kw 乘以 663，然后除以 1000（向下舍入）。

HTLC-success transaction 的费用：

• 如果 option_anchors 适用：
  1. 必须为 0。
• 否则，必须计算以匹配：
  1. 将 feerate_per_kw 乘以 703，然后除以 1000（向下舍入）。

commitment transaction 的基本费用：

• 必须计算以匹配：
  1. 从 weight = 724 开始（如果 option_anchors 适用，则为 1124）。
  2. 对于每个 committed HTLC，如果该输出没有按照 Trimmed Outputs 中指定的进行 trimmed，则将 172 添加到 weight。
  3. 将 feerate_per_kw 乘以 weight，然后除以 1000（向下舍入）。

示例

例如，假设 feerate_per_kw 为 5000，dust_limit_satoshis 为 546 satoshis，并且 commitment transaction 具有：

• 两个 offered HTLC，分别为 5000000 和 1000000 millisatoshis（5000 和 1000 satoshis）
• 两个 received HTLC，分别为 7000000 和 800000 millisatoshis（7000 和 800 satoshis）

HTLC-timeout transaction weight 为 663，因此费用为 3315 satoshis。 HTLC-success transaction weight 为 703，因此费用为 3515 satoshis。

commitment transaction weight 计算如下：

• weight 从 724 开始。

• 5000 satoshis 的 offered HTLC 高于 546 + 3315，并导致：

  • commitment transaction 中的 5000 satoshi 的输出
  • 花费此输出的 5000 - 3315 satoshis 的 HTLC-timeout transaction
  • weight 增加到 896

• 1000 satoshis 的 offered HTLC 低于 546 + 3315，因此会被 trimmed。

• 7000 satoshis 的 received HTLC 高于 546 + 3515，并导致：

  • commitment transaction 中的 7000 satoshi 的输出
  • 花费此输出的 7000 - 3515 satoshis 的 HTLC-success transaction
  • weight 增加到 1068

• 800 satoshis 的 received HTLC 低于 546 + 3515，因此会被 trimmed。

基本 commitment transaction 费用为 5340 satoshi；实际 费用（添加会产生 dust output 的 1000 和 800 satoshi HTLC）为 7140 satoshi。如果 to_local 或 to_remote 输出低于 dust_limit_satoshis，则最终费用可能会更高。

费用支付

基本 commitment transaction 费用以及 to_local_anchor 和 to_remote_anchor 输出的金额从 funder 的金额中提取；与通道储备金相关的 funder 的 commitment tx 输出的限制如 BOLT #2 中所述适用。

请注意，在从支付给 funder 的输出中减去费用金额后，该输出可能低于 dust_limit_satoshis，因此也会产生费用。

一个节点：

• 如果产生的费率太低：
  • 可以发送 warning 并关闭连接，或者发送 error 并使通道失败。

计算协作交易的费用

对于使用交互式协议构建的交易，费用由交易的每一方支付，费率在启动期间确定，启动者承担公共交易字段的费用。

Dust Limits

dust_limit_satoshis 参数用于配置阈值，低于该阈值节点将不产生链上交易输出。

Bitcoin 中没有共识规则使低于 dust 阈值的输出无效或无法花费，但流行的实现中的策略规则将阻止包含此类输出的转发交易。

Bitcoin Core 定义了以下 dust 阈值：

• pay to pubkey hash (p2pkh): 546 satoshis
• pay to script hash (p2sh): 540 satoshis
• pay to witness pubkey hash (p2wpkh): 294 satoshis
• pay to witness script hash (p2wsh): 330 satoshis
• unknown segwit versions: 354 satoshis

此计算的原理（在此处实现：here）将在以下各节中解释。

在所有这些部分中，计算都是按照 Bitcoin Core 的实现，使用 3000 sat/kB 的费率完成的。

Pay to pubkey hash (p2pkh)

p2pkh 输出为 34 字节：

• 输出金额为 8 字节
• 脚本长度为 1 字节
• 脚本为 25 字节 (OP_DUP OP_HASH160 20 20-bytes OP_EQUALVERIFY OP_CHECKSIG)

p2pkh 输入至少为 148 字节：

• 上一个输出为 36 字节（32 字节哈希 + 4 字节索引）
• 序列为 4 字节
• 脚本 sig 长度为 1 字节
• 脚本 sig 为 107 字节：
  • 项目计数为 1 字节
  • 签名长度为 1 字节
  • 签名为 71 字节
  • 公钥长度为 1 字节
  • 公钥为 33 字节

然后，p2pkh dust 阈值为 (34 + 148) * 3000 / 1000 = 546 satoshis

Pay to script hash (p2sh)

p2sh 输出为 32 字节：

• 输出金额为 8 字节
• 脚本长度为 1 字节
• 脚本为 23 字节 (OP_HASH160 20 20-bytes OP_EQUAL)

p2sh 输入没有固定大小，因为它取决于底层的脚本，因此我们使用 148 字节作为下限。

然后，p2sh dust 阈值为 (32 + 148) * 3000 / 1000 = 540 satoshis

Pay to witness pubkey hash (p2wpkh)

p2wpkh 输出为 31 字节：

• 输出金额为 8 字节
• 脚本长度为 1 字节
• 脚本为 22 字节 (OP_0 20 20-bytes)

p2wpkh 输入至少为 67 字节（取决于签名长度）：

• 上一个输出为 36 字节（32 字节哈希 + 4 字节索引）
• 序列为 4 字节
• 脚本 sig 长度为 1 字节
• 见证为 26 字节（从 26.75 向下舍入，应用了 75% segwit 折扣）：
  • 项目计数为 1 字节
  • 签名长度为 1 字节
  • 签名为 71 字节
  • 公钥长度为 1 字节
  • 公钥为 33 字节

然后，p2wpkh dust 阈值为 (31 + 67) * 3000 / 1000 = 294 satoshis

Pay to witness script hash (p2wsh)

p2wsh 输出为 43 字节：

• 输出金额为 8 字节
• 脚本长度为 1 字节
• 脚本为 34 字节 (OP_0 32 32-bytes)

p2wsh 输入没有固定大小，因为它取决于底层的脚本，因此我们使用 67 字节作为下限。

然后，p2wsh dust 阈值为 (43 + 67) * 3000 / 1000 = 330 satoshis

Unknown segwit versions

未知的 segwit 输出最多为 51 字节：

• 输出金额为 8 字节
• 脚本长度为 1 字节
• 脚本为 42 字节（包括 OP_1 到 OP_16，后跟 2 到 40 字节的单个推送) 输入的大小不固定，因为它取决于底层的脚本，所以我们使用 67 字节作为下限。

未知的隔离见证版本 dust threshold 随后是 (51 + 67) * 3000 / 1000 = 354 satoshis

Commitment Transaction Construction （承诺交易构建）

本节将前面的章节联系起来，详细说明为一个对等方构建承诺交易的算法：给定该对等方的 dust_limit_satoshis、当前的 feerate_per_kw、应付给每个对等方的金额（to_local 和 to_remote），以及所有已提交的 HTLC：

1. 按照Commitment Transaction（承诺交易）中的规定，初始化承诺交易的输入和 locktime。
2. 计算哪些已提交的 HTLC 需要被 trimmed（参见Trimmed Outputs（修剪后的输出））。
3. 计算基本commitment transaction fee（承诺交易费用）。
4. 从 funder（to_local 或 to_remote）中减去此基本费用。 如果 option_anchors 适用于承诺交易，还需要从 funder（to_local 或 to_remote）中减去两倍的固定锚点大小，即 330 sats。
5. 对于每个 offered HTLC，如果它没有被 trimmed，则添加一个offered HTLC output（offered HTLC 输出）。
6. 对于每个 received HTLC，如果它没有被 trimmed，则添加一个received HTLC output（received HTLC 输出）。
7. 如果 to_local 金额大于或等于 dust_limit_satoshis，则添加一个 to_local output（to_local 输出）。
8. 如果 to_remote 金额大于或等于 dust_limit_satoshis，则添加一个 to_remote output（to_remote 输出）。
9. 如果 option_anchors 适用于承诺交易：
   • 如果 to_local 存在或有未被trimmed的 HTLC，则添加一个 to_local_anchor output（to_local_anchor 输出）
   • 如果 to_remote 存在或有未被trimmed的 HTLC，则添加一个 to_remote_anchor output（to_remote_anchor 输出）
10. 将输出排序为 BIP 69+CLTV order（BIP 69+CLTV 顺序）。

Keys（密钥）

Key Derivation（密钥推导）

每个承诺交易使用一个唯一的 localpubkey。 HTLC-success 和 HTLC-timeout 交易使用 local_delayedpubkey 和 revocationpubkey。 这些会根据 per_commitment_point 为每个交易更改。

更改密钥的原因是为了可以将对已撤销交易的无需信任的监视外包。这样的 watcher 不应该能够确定承诺交易的内容 —— 即使 watcher 知道要监视哪个交易 ID，并且可以合理地猜测可能包含哪些 HTLC 和余额。尽管如此，为了避免存储每个承诺交易，可以向 watcher 提供 per_commitment_secret 值（可以紧凑地存储这些值）以及用于重新生成 penalty transaction（惩罚交易）所需的脚本的 revocation_basepoint 和 delayed_payment_basepoint；因此，只需要向 watcher 提供（并存储）每个 penalty input（惩罚输入）的签名。

每次更改 localpubkey 确保了 commitment transaction ID 无法被猜测，除非在没有 to_local 输出的简单情况下，因为每个承诺交易在其输出脚本中使用一个 ID。拆分 local_delayedpubkey（penalty transaction（惩罚交易）所需），允许它与 watcher 共享，而不会泄露 localpubkey；即使两个对等方使用相同的 watcher，也不会泄露任何信息。

最后，即使在正常的单方面关闭的情况下，HTLC-success 和/或 HTLC-timeout 交易也不会向 watcher 透露任何信息，因为它不知道相应的 per_commitment_secret，并且无法将 local_delayedpubkey 或 revocationpubkey 与其 base 关联起来。

为了提高效率，密钥是从一系列 per-commitment secrets 生成的，这些 secrets 是从单个 seed 生成的，这允许接收者紧凑地存储它们（参见下文）。

localpubkey、local_htlcpubkey、remote_htlcpubkey、local_delayedpubkey 和 remote_delayedpubkey 推导

这些公钥只是通过从它们的 base points（基点）相加生成的：

pubkey = basepoint + SHA256(per_commitment_point || basepoint) * G

• localpubkey 使用本地节点的 payment_basepoint；
• local_htlcpubkey 使用本地节点的 htlc_basepoint；
• remote_htlcpubkey 使用远程节点的 htlc_basepoint；
• local_delayedpubkey 使用本地节点的 delayed_payment_basepoint；
• remote_delayedpubkey 使用远程节点的 delayed_payment_basepoint。

如果知道 basepoint secrets（即仅与 localpubkey、local_htlcpubkey 和 local_delayedpubkey 对应的私钥），则可以类似地推导出相应的私钥：

privkey = basepoint_secret + SHA256(per_commitment_point || basepoint)

remotepubkey 推导

remotepubkey 只是远程节点的 payment_basepoint。

这意味着即使节点丢失了数据并且不知道相应的 per_commitment_point，它也可以花费 commitment transaction（承诺交易）。如果看守塔在链上看到一个只包含 to_remote 输出的交易，那么它可以关联到给它的交易，但是这样的交易不需要任何强制执行，也不应该交给看守塔。

revocationpubkey 推导

revocationpubkey 是一个盲化的密钥：当本地节点希望为远程节点创建一个新的承诺时，它使用自己的 revocation_basepoint 和远程节点的 per_commitment_point 来派生该承诺的新的 revocationpubkey。在远程节点揭示所使用的 per_commitment_secret 之后（从而撤销该承诺），本地节点可以推导出 revocationprivkey，因为它现在知道派生密钥所需的两个 secrets（revocation_basepoint_secret 和 per_commitment_secret）。

per_commitment_point 使用椭圆曲线乘法生成：

per_commitment_point = per_commitment_secret * G

这用于从远程节点的 revocation_basepoint 派生撤销公钥：

revocationpubkey = revocation_basepoint * SHA256(revocation_basepoint || per_commitment_point) + per_commitment_point * SHA256(per_commitment_point || revocation_basepoint)

这种构造确保了提供 basepoint 的节点和提供 per_commitment_point 的节点都无法在没有另一个节点的 secret 的情况下知道私钥。

一旦知道 per_commitment_secret，就可以派生相应的私钥：

revocationprivkey = revocation_basepoint_secret * SHA256(revocation_basepoint || per_commitment_point) + per_commitment_secret * SHA256(per_commitment_point || revocation_basepoint)

Per-commitment Secret Requirements (Per-commitment Secret 要求)

一个节点：

• 必须为每个连接选择一个不可猜测的 256 位 seed，
• 必须不泄露该 seed。

最多可以生成 (2^48 - 1) 个 per-commitment secrets（每次承诺的密钥）。

使用的第一个 secret（密钥）：

• 必须是索引 281474976710655，
  • 从那里，索引递减。

第 i 个 secret P：

• 必须与此算法的输出匹配：

  generate_from_seed(seed, I):
  P = seed
  for B in 47 down to 0:
      if B set in I:
          flip(B) in P
          P = SHA256(P)
  return P

其中 "flip(B)" 交替该值 (B div 8) 的 (B mod 8) 位。因此，“flip(0) in e3b0…” 是 “e2b0…”，而 "flip(10) in "e3b0..." 是 "e3b4..."。

接收节点：

• 可以存储所有以前的 per-commitment secrets（每次承诺的密钥）。
• 可以从 compact representation（紧凑表示）中计算它们，如下所述。

Efficient Per-commitment Secret Storage（高效的 Per-commitment Secret 存储）

一系列密钥的接收者可以将它们紧凑地存储在 49 个（value，index）对的数组中。因为，对于 2^X 边界上的给定密钥，可以推导出到下一个 2^X 边界的所有密钥；并且总是以递减的顺序从 0xFFFFFFFFFFFF 接收密钥。

在二进制中，将任何索引视为 prefix（前缀），后跟一些尾随 0 会很有帮助。你可以为任何与此 prefix 匹配的索引推导出密钥。

例如，密钥 0xFFFFFFFFFFF0 允许为 0xFFFFFFFFFFF1 到 0xFFFFFFFFFFFF（包括 0xFFFFFFFFFFFF）推导出密钥；密钥 0xFFFFFFFFFF08 允许为 0xFFFFFFFFFF09 到 0xFFFFFFFFFF0F（包括 0xFFFFFFFFFF0F）推导出密钥。

这是使用上面 generate_from_seed 的一个小的概括来完成的：

# 返回给定 base secret 的第 i 个密钥，其索引具有相同的 bits..47。
derive_secret(base, bits, I):
    P = base
    for B in bits - 1 down to 0:
        if B set in I:
            flip(B) in P
            P = SHA256(P)
    return P

只需要 saved（保存）每个唯一前缀的一个密钥；实际上，尾随 0 的数量被计数，这决定了密钥存储在存储数组中的位置：

# 又名 计算尾随 0
where_to_put_secret(I):
    for B in 0 to 47:
        if testbit(I) in B == 1:
            return B
    # I = 0，这是 seed（种子）。
    return 48

需要对所有以前的密钥进行双重检查，以确保它们可以正确推导；如果此检查失败，则密钥不是从同一 seed（种子）生成的：

insert_secret(secret, I):
    B = where_to_put_secret(I)

    # 这会跟踪遍历过程中每个 bucket 中密钥的索引。
    for b in 0 to B:
        if derive_secret(secret, B, known[b].index) != known[b].secret:
            error The secret for I is incorrect
            return

    # 假设这会自动根据需要扩展 known[]。
    known[B].index = I
    known[B].secret = secret

最后，如果需要派生索引 I 处的未知密钥，则必须发现可以使用哪个已知密钥来派生它。最简单的方法是迭代所有已知的密钥，并测试是否可以使用每个密钥来派生未知的密钥：

derive_old_secret(I):
    for b in 0 to len(secrets):
        # 屏蔽索引的非零前缀。
        MASK = ~((1 << b) - 1)
        if (I & MASK) == secrets[b].index:
            return derive_secret(known, i, I)
    error Index 'I' hasn't been received yet.

这看起来很复杂，但请记住，条目 b 中的索引有 b 个尾随 0；mask和比较只是检查每个 bucket 中的索引是否是所需索引的前缀。

在以下内容中：

• 假定 local 是 funder（出资方）。
• 私钥显示为 32 个字节加上一个尾随 1（Bitcoin 中 “compressed” 私钥的约定，即公钥被压缩的密钥）。
• 交易签名都是确定性的，使用 RFC6979（使用 HMAC-SHA256）。有效的签名必须对相关交易的所有输入和输出进行签名（即必须使用 SIGHASH_ALL 签名哈希 创建），除非另有明确说明。请注意，客户端必须以 compact encoding（紧凑编码） 发送签名，而不是以 Bitcoin-script 格式发送，因此签名哈希字节不会被传输。

funding transaction(资金交易)的输入是使用一个测试链创建的，该测试链有以下前两个块；第二个块包含一个可花费的 coinbase（请注意，正如 BOLT #2 中详述的，这样的 P2PKH 输入是不明智的，但提供了最简单的示例）：

### 存储测试

这些测试了可选的紧凑存储系统。 在许多情况下，在显示其父项之前无法确定不正确的条目：一个条目专门损坏，以及其所有子条目。

对于这些测试，使用 `0xFFF...FF` 的种子，并且使用 `0x000...00` 为不正确的条目设定种子。
