Transactions

Transaction Input and Output Ordering

Lexicographic ordering: see BIP69. In the case of identical HTLC outputs, the outputs are ordered in increasing cltv_expiry order.

Rationale

Two offered HTLCs which have the same amount_msat and payment_hash will have identical outputs, even if their cltv_expiry differs. This only matters because the same ordering is used to send htlc_signatures and the HTLC transactions themselves are different, thus the two peers must agree on the canonical ordering for this case.

Use of Segwit

Most transaction outputs used here are pay-to-witness-script-hash^BIP141 (P2WSH) outputs: the Segwit version of P2SH. To spend such outputs, the last item on the witness stack must be the actual script that was used to generate the P2WSH output that is being spent. This last item has been omitted for brevity in the rest of this document.

Funding Transaction Output

• The funding output script is a P2WSH to:

2 <pubkey1> <pubkey2> 2 OP_CHECKMULTISIG

• Where pubkey1 is the numerically lesser of the two DER-encoded funding_pubkey and where pubkey2 is the numerically greater of the two.

Commitment Transaction

• version: 2
• locktime: upper 8 bits are 0x20, lower 24 bits are the lower 24 bits of the obscured commitment number
• txin count: 1
  • txin[0] outpoint: txid and output_index from funding_created message
  • txin[0] sequence: upper 8 bits are 0x80, lower 24 bits are upper 24 bits of the obscured commitment number
  • txin[0] script bytes: 0
  • txin[0] witness: 0 <signature_for_pubkey1> <signature_for_pubkey2>

The 48-bit commitment number is obscured by XOR with the lower 48 bits of:

SHA256(payment_basepoint from open_channel || payment_basepoint from accept_channel)

This obscures the number of commitments made on the channel in the case of unilateral close, yet still provides a useful index for both nodes (who know the payment_basepoints) to quickly find a revoked commitment transaction.

Commitment Transaction Outputs

To allow an opportunity for penalty transactions, in case of a revoked commitment transaction, all outputs that return funds to the owner of the commitment transaction (a.k.a. the "local node") must be delayed for to_self_delay blocks. This delay is done in a second-stage HTLC transaction (HTLC-success for HTLCs accepted by the local node, HTLC-timeout for HTLCs offered by the local node).

The reason for the separate transaction stage for HTLC outputs is so that HTLCs can timeout or be fulfilled even though they are within the to_self_delay delay. Otherwise, the required minimum timeout on HTLCs is lengthened by this delay, causing longer timeouts for HTLCs traversing the network.

The amounts for each output MUST be rounded down to whole satoshis. If this amount, minus the fees for the HTLC transaction, is less than the dust_limit_satoshis set by the owner of the commitment transaction, the output MUST NOT be produced (thus the funds add to fees).

to_local Output

This output sends funds back to the owner of this commitment transaction and thus must be timelocked using OP_CHECKSEQUENCEVERIFY. It can be claimed, without delay, by the other party if they know the revocation private key. The output is a version-0 P2WSH, with a witness script:

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

The output is spent by a transaction with nSequence field set to to_self_delay (which can only be valid after that duration has passed) and witness:

<local_delayedsig> 0

If a revoked commitment transaction is published, the other party can spend this output immediately with the following witness:

<revocation_sig> 1

to_remote Output

This output sends funds to the other peer and thus is a simple P2WPKH to remotepubkey.

Offered HTLC Outputs

This output sends funds to either an HTLC-timeout transaction after the HTLC-timeout or to the remote node using the payment preimage or the revocation key. The output is a P2WSH, with a witness script:

# To remote node with revocation key
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
        # To local node via HTLC-timeout transaction (timelocked).
        OP_DROP 2 OP_SWAP <local_htlcpubkey> 2 OP_CHECKMULTISIG
    OP_ELSE
        # To remote node with preimage.
        OP_HASH160 <RIPEMD160(payment_hash)> OP_EQUALVERIFY
        OP_CHECKSIG
    OP_ENDIF
OP_ENDIF

The remote node can redeem the HTLC with the witness:

<remotehtlcsig> <payment_preimage>

If a revoked commitment transaction is published, the remote node can spend this output immediately with the following witness:

<revocation_sig> <revocationpubkey>

The sending node can use the HTLC-timeout transaction to timeout the HTLC once the HTLC is expired, as shown below. This is the only way that the local node can timeout the HTLC, and this branch requires <remotehtlcsig>, which ensures that the local node cannot prematurely timeout the HTLC since the HTLC-timeout transaction has cltv_expiry as its specified locktime. The local node must also wait to_self_delay before accessing these funds, allowing for the remote node to claim these funds if the transaction has been revoked.

Received HTLC Outputs

This output sends funds to either the remote node after the HTLC-timeout or using the revocation key, or to an HTLC-success transaction with a successful payment preimage. The output is a P2WSH, with a witness script:

# To remote node with revocation key
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
        # To local node via HTLC-success transaction.
        OP_HASH160 <RIPEMD160(payment_hash)> OP_EQUALVERIFY
        2 OP_SWAP <local_htlcpubkey> 2 OP_CHECKMULTISIG
    OP_ELSE
        # To remote node after timeout.
        OP_DROP <cltv_expiry> OP_CHECKLOCKTIMEVERIFY OP_DROP
        OP_CHECKSIG
    OP_ENDIF
OP_ENDIF

To timeout the HTLC, the remote node spends it with the witness:

<remotehtlcsig> 0

If a revoked commitment transaction is published, the remote node can spend this output immediately with the following witness:

<revocation_sig> <revocationpubkey>

To redeem the HTLC, the HTLC-success transaction is used as detailed below. This is the only way that the local node can spend the HTLC, since this branch requires <remotehtlcsig>, which ensures that the local node must wait to_self_delay before accessing these funds allowing for the remote node to claim these funds if the transaction has been revoked.

Trimmed Outputs

Each peer specifies a dust_limit_satoshis below which outputs should not be produced; these outputs that are not produced are termed "trimmed". A trimmed output is considered too small to be worth creating and is instead added to the commitment transaction fee. For HTLCs, it needs to be taken into account that the second-stage HTLC transaction may also be below the limit.

Requirements

The base fee:

• before the commitment transaction outputs are determined:
  • MUST be subtracted from the to_local or to_remote outputs, as specified in Fee Calculation.

The commitment transaction:

• if the amount of the commitment transaction to_local output would be less than dust_limit_satoshis set by the transaction owner:
  • MUST NOT contain that output.
• otherwise:
  • MUST be generated as specified in to_local Output.
• if the amount of the commitment transaction to_remote output would be less than dust_limit_satoshis set by the transaction owner:
  • MUST NOT contain that output.
• otherwise:
  • MUST be generated as specified in to_remote Output.
• for every offered HTLC:
  • if the HTLC amount minus the HTLC-timeout fee would be less than dust_limit_satoshis set by the transaction owner:
    • MUST NOT contain that output.
  • otherwise:
    • MUST be generated as specified in Offered HTLC Outputs.
• for every received HTLC:
  • if the HTLC amount minus the HTLC-success fee would be less than dust_limit_satoshis set by the transaction owner:
    • MUST NOT contain that output.
  • otherwise:
    • MUST be generated as specified in Received HTLC Outputs.

HTLC-Timeout and HTLC-Success Transactions

These HTLC transactions are almost identical, except the HTLC-timeout transaction is timelocked. Both HTLC-timeout/HTLC-success transactions can be spent by a valid penalty transaction.

• version: 2
• locktime: 0 for HTLC-success, cltv_expiry for HTLC-timeout
• txin count: 1
  • txin[0] outpoint: txid of the commitment transaction and output_index of the matching HTLC output for the HTLC transaction
  • txin[0] sequence: 0
  • txin[0] script bytes: 0
  • txin[0] witness stack: 0 <remotehtlcsig> <localhtlcsig> <payment_preimage> for HTLC-success, 0 <remotehtlcsig> <localhtlcsig> 0 for HTLC-timeout
• txout count: 1
  • txout[0] amount: the HTLC amount minus fees (see Fee Calculation)
  • txout[0] script: version-0 P2WSH with witness script as shown below

The witness script for the output is:

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

To spend this via penalty, the remote node uses a witness stack <revocationsig> 1, and to collect the output, the local node uses an input with nSequence to_self_delay and a witness stack <local_delayedsig> 0.

Closing Transaction

Note that there are two possible variants for each node.

• version: 2
• locktime: 0
• txin count: 1
  • txin[0] outpoint: txid and output_index from funding_created message
  • txin[0] sequence: 0xFFFFFFFF
  • txin[0] script bytes: 0
  • txin[0] witness: 0 <signature_for_pubkey1> <signature_for_pubkey2>
• txout count: 0, 1 or 2
  • txout amount: final balance to be paid to one node (minus fee_satoshis from closing_signed, if this peer funded the channel)
  • txout script: as specified in that node's scriptpubkey in its shutdown message

Requirements

Each node offering a signature:

• MUST round each output down to whole satoshis.
• MUST subtract the fee given by fee_satoshis from the output to the funder.
• MUST remove any output below its own dust_limit_satoshis.
• MAY eliminate its own output.

Rationale

There is a possibility of irreparable differences on closing if one node considers the other's output too small to allow propagation on the Bitcoin network (a.k.a. "dust"), and that other node instead considers that output too valuable to discard. This is why each side uses its own dust_limit_satoshis, and the result can be a signature validation failure, if they disagree on what the closing transaction should look like.

However, if one side chooses to eliminate its own output, there's no reason for the other side to fail the closing protocol; so this is explicitly allowed. The signature indicates which variant has been used.

There will be at least one output, if the funding amount is greater than twice dust_limit_satoshis.

Fees

Fee Calculation

The fee calculation for both commitment transactions and HTLC transactions is based on the current feerate_per_kw and the expected weight of the transaction.

The actual and expected weights vary for several reasons:

• Bitcoin uses DER-encoded signatures, which vary in size.
• Bitcoin also uses variable-length integers, so a large number of outputs will take 3 bytes to encode rather than 1.
• The to_remote output may be below the dust limit.
• The to_local output may be below the dust limit once fees are extracted.

Thus, a simplified formula for expected weight is used, which assumes:

• Signatures are 73 bytes long (the maximum length).
• There are a small number of outputs (thus 1 byte to count them).
• There are always both a to_local output and a to_remote output.

This yields the following expected weights (details of the computation in Appendix A):

Commitment weight:   724 + 172 * num-untrimmed-htlc-outputs
HTLC-timeout weight: 663
HTLC-success weight: 703

Note the reference to the "base fee" for a commitment transaction in the requirements below, which is what the funder pays. The actual fee may be higher than the amount calculated here, due to rounding and trimmed outputs.

Requirements

The fee for an HTLC-timeout transaction:

• MUST BE calculated to match:
  1. Multiply feerate_per_kw by 663 and divide by 1000 (rounding down).

The fee for an HTLC-success transaction:

• MUST BE calculated to match:
  1. Multiply feerate_per_kw by 703 and divide by 1000 (rounding down).

The base fee for a commitment transaction:

• MUST be calculated to match:
  1. Start with weight = 724.
  2. For each committed HTLC, if that output is not trimmed as specified in Trimmed Outputs, add 172 to weight.
  3. Multiply feerate_per_kw by weight, divide by 1000 (rounding down).

Example

For example, suppose there is a feerate_per_kw of 5000, a dust_limit_satoshis of 546 satoshis, and a commitment transaction with:

• two offered HTLCs of 5000000 and 1000000 millisatoshis (5000 and 1000 satoshis)
• two received HTLCs of 7000000 and 800000 millisatoshis (7000 and 800 satoshis)

The HTLC-timeout transaction weight is 663, and thus the fee is 3315 satoshis. The HTLC-success transaction weight is 703, and thus the fee is 3515 satoshis

The commitment transaction weight is calculated as follows:

• weight starts at 724.

• The offered HTLC of 5000 satoshis is above 546 + 3315 and results in:

  • an output of 5000 satoshi in the commitment transaction
  • an HTLC-timeout transaction of 5000 - 3315 satoshis that spends this output
  • weight increases to 896

• The offered HTLC of 1000 satoshis is below 546 + 3315 so it is trimmed.

• The received HTLC of 7000 satoshis is above 546 + 3515 and results in:

  • an output of 7000 satoshi in the commitment transaction
  • an HTLC-success transaction of 7000 - 3515 satoshis that spends this output
  • weight increases to 1068

• The received HTLC of 800 satoshis is below 546 + 3515 so it is trimmed.

The base commitment transaction fee is 5340 satoshi; the actual fee (which adds the 1000 and 800 satoshi HTLCs that would make dust outputs) is 7140 satoshi. The final fee may be even higher if the to_local or to_remote outputs fall below dust_limit_satoshis.

Fee Payment

Base commitment transaction fees are extracted from the funder's amount; if that amount is insufficient, the entire amount of the funder's output is used.

Note that after the fee amount is subtracted from the to-funder output, that output may be below dust_limit_satoshis, and thus will also contribute to fees.

A node:

• if the resulting fee rate is too low:
  • MAY fail the channel.

Commitment Transaction Construction

This section ties the previous sections together to detail the algorithm for constructing the commitment transaction for one peer: given that peer's dust_limit_satoshis, the current feerate_per_kw, the amounts due to each peer (to_local and to_remote), and all committed HTLCs:

1. Initialize the commitment transaction input and locktime, as specified in Commitment Transaction.
2. Calculate which committed HTLCs need to be trimmed (see Trimmed Outputs).
3. Calculate the base commitment transaction fee.
4. Subtract this base fee from the funder (either to_local or to_remote), with a floor of 0 (see Fee Payment).
5. For every offered HTLC, if it is not trimmed, add an offered HTLC output.
6. For every received HTLC, if it is not trimmed, add an received HTLC output.
7. If the to_local amount is greater or equal to dust_limit_satoshis, add a to_local output.
8. If the to_remote amount is greater or equal to dust_limit_satoshis, add a to_remote output.
9. Sort the outputs into BIP 69+CLTV order.

Keys

Key Derivation

Each commitment transaction uses a unique localpubkey, and a remotepubkey. The HTLC-success and HTLC-timeout transactions use local_delayedpubkey and revocationpubkey. These are changed for every transaction based on the per_commitment_point, with the exception of remotepubkey if option_static_remotekey is negotiated.

The reason for key change is so that trustless watching for revoked transactions can be outsourced. Such a watcher should not be able to determine the contents of a commitment transaction — even if the watcher knows which transaction ID to watch for and can make a reasonable guess as to which HTLCs and balances may be included. Nonetheless, to avoid storage of every commitment transaction, a watcher can be given the per_commitment_secret values (which can be stored compactly) and the revocation_basepoint and delayed_payment_basepoint used to regenerate the scripts required for the penalty transaction; thus, a watcher need only be given (and store) the signatures for each penalty input.

Changing the localpubkey every time ensures that commitment transaction ID cannot be guessed except in the trivial case where there is no to_local output, as every commitment transaction uses an ID in its output script. Splitting the local_delayedpubkey, which is required for the penalty transaction, allows it to be shared with the watcher without revealing localpubkey; even if both peers use the same watcher, nothing is revealed.

Finally, even in the case of normal unilateral close, the HTLC-success and/or HTLC-timeout transactions do not reveal anything to the watcher, as it does not know the corresponding per_commitment_secret and cannot relate the local_delayedpubkey or revocationpubkey with their bases.

For efficiency, keys are generated from a series of per-commitment secrets that are generated from a single seed, which allows the receiver to compactly store them (see below).

localpubkey, local_htlcpubkey, remote_htlcpubkey, local_delayedpubkey, and remote_delayedpubkey Derivation

These pubkeys are simply generated by addition from their base points:

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

The localpubkey uses the local node's payment_basepoint; the local_htlcpubkey uses the local node's htlc_basepoint; the remote_htlcpubkey uses the remote node's htlc_basepoint; the local_delayedpubkey uses the local node's delayed_payment_basepoint; and the remote_delayedpubkey uses the remote node's delayed_payment_basepoint.

The corresponding private keys can be similarly derived, if the basepoint secrets are known (i.e. the private keys corresponding to localpubkey, local_htlcpubkey, and local_delayedpubkey only):

privkey = basepoint_secret + SHA256(per_commitment_point || basepoint)

remotepubkey Derivation

If option_static_remotekey is negotiated the remotepubkey is simply the remote node's payment_basepoint, otherwise it is calculated as above using the remote node's payment_basepoint.

The simplified derivation means that a node can spend a commitment transaction even if it has lost data and doesn't know the corresponding per_commitment_point. A watchtower could correlate transactions given to it which only have a to_remote output if it sees one of them onchain, but such transactions do not need any enforcement and should not be handed to a watchtower.

revocationpubkey Derivation

The revocationpubkey is a blinded key: when the local node wishes to create a new commitment for the remote node, it uses its own revocation_basepoint and the remote node's per_commitment_point to derive a new revocationpubkey for the commitment. After the remote node reveals the per_commitment_secret used (thereby revoking that commitment), the local node can then derive the revocationprivkey, as it now knows the two secrets necessary to derive the key (revocation_basepoint_secret and per_commitment_secret).

The per_commitment_point is generated using elliptic-curve multiplication:

per_commitment_point = per_commitment_secret * G

And this is used to derive the revocation pubkey from the remote node's revocation_basepoint:

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

This construction ensures that neither the node providing the basepoint nor the node providing the per_commitment_point can know the private key without the other node's secret.

The corresponding private key can be derived once the per_commitment_secret is known:

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

Per-commitment Secret Requirements

A node:

• MUST select an unguessable 256-bit seed for each connection,
• MUST NOT reveal the seed.

Up to (2^48 - 1) per-commitment secrets can be generated.

The first secret used:

• MUST be index 281474976710655,
  • and from there, the index is decremented.

The I'th secret P:

• MUST match the output of this algorithm:

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

Where "flip(B)" alternates the B'th least significant bit in the value P.

The receiving node:

• MAY store all previous per-commitment secrets.
• MAY calculate them from a compact representation, as described below.

Efficient Per-commitment Secret Storage

The receiver of a series of secrets can store them compactly in an array of 49 (value,index) pairs. Because, for a given secret on a 2^X boundary, all secrets up to the next 2^X boundary can be derived; and secrets are always received in descending order starting at 0xFFFFFFFFFFFF.

In binary, it's helpful to think of any index in terms of a prefix, followed by some trailing 0s. You can derive the secret for any index that matches this prefix.

For example, secret 0xFFFFFFFFFFF0 allows the secrets to be derived for 0xFFFFFFFFFFF1 through 0xFFFFFFFFFFFF, inclusive; and secret 0xFFFFFFFFFF08 allows the secrets to be derived for 0xFFFFFFFFFF09 through 0xFFFFFFFFFF0F, inclusive.

This is done using a slight generalization of generate_from_seed above:

# Return I'th secret given base secret whose index has bits..47 the same.
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

Only one secret for each unique prefix need be saved; in effect, the number of trailing 0s is counted, and this determines where in the storage array the secret is stored:

# a.k.a. count trailing 0s
where_to_put_secret(I):
    for B in 0 to 47:
        if testbit(I) in B == 1:
            return B
    # I = 0, this is the seed.
    return 48

A double-check, that all previous secrets derive correctly, is needed; if this check fails, the secrets were not generated from the same seed:

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

    # This tracks the index of the secret in each bucket across the traversal.
    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

    # Assuming this automatically extends known[] as required.
    known[B].index = I
    known[B].secret = secret

Finally, if an unknown secret at index I needs be derived, it must be discovered which known secret can be used to derive it. The simplest method is iterating over all the known secrets, and testing if each can be used to derive the unknown secret:

derive_old_secret(I):
    for b in 0 to len(secrets):
        # Mask off the non-zero prefix of the index.
        MASK = ~((1 << b) - 1)
        if (I & MASK) == secrets[b].index:
            return derive_secret(known, i, I)
    error Index 'I' hasn't been received yet.

This looks complicated, but remember that the index in entry b has b trailing 0s; the mask and compare simply checks if the index at each bucket is a prefix of the desired index.

	- lock_time: 4 bytes

Multiplying non-witness data by 4 results in a weight of:

// 500 + 172 * num-htlc-outputs weight
commitment_transaction_weight = 4 * commitment_transaction

// 224 weight
witness_weight = witness_header + witness

overall_weight = 500 + 172 * num-htlc-outputs + 224 weight

Appendix B: Funding Transaction Test Vectors

In the following:

• It's assumed that local is the funder.
• Private keys are displayed as 32 bytes plus a trailing 1 (Bitcoin's convention for "compressed" private keys, i.e. keys for which the public key is compressed).
• Transaction signatures are all deterministic, using RFC6979 (using HMAC-SHA256). A valid signature MUST sign all inputs and outputs of the relevant transaction (i.e. MUST be created with a SIGHASH_ALL signature hash), unless explicitly stated otherwise. Note that clients MUST send the signature in compact encoding and not in Bitcoin-script format, thus the signature hash byte is not transmitted.

The input for the funding transaction was created using a test chain with the following first two blocks; the second block contains a spendable coinbase (note that such a P2PKH input is inadvisable, as detailed in BOLT #2, but provides the simplest example):

Block 0 (genesis): 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

The funding transaction is paid to the following pubkeys:

local_funding_pubkey: 023da092f6980e58d2c037173180e9a465476026ee50f96695963e8efe436f54eb

The funding transaction has a single input and a change output (order determined by BIP69 in this case):

input txid: fd2105607605d2302994ffea703b09f66b6351816ee737a93e42a841ea20bbad

# feerate_per_kw: 15000
change satoshis: 4989986080

The resulting funding transaction is:

Appendix C: Commitment and HTLC Transaction Test Vectors

In the following:

• local transactions are considered, which implies that all payments to local are delayed.
• It's assumed that local is the funder.
• Private keys are displayed as 32 bytes plus a trailing 1 (Bitcoin's convention for "compressed" private keys, i.e. keys for which the public key is compressed).
• Transaction signatures are all deterministic, using RFC6979 (using HMAC-SHA256).

To start, common basic parameters for each test vector are defined: the HTLCs are not used for the first "simple commitment tx with no HTLCs" test.

Storage Tests

These test the optional compact storage system. In many cases, an incorrect entry cannot be determined until its parent is revealed: an entry is specifically corrupted, along with all its children.

For these tests a seed of 0xFFF...FF is used, and incorrect entries are seeded with 0x000...00.
