Transactions

Transaction input and output ordering

Lexicographic ordering as per BIP 69.

Use of segwit

Most transaction outputs used here are 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 pay-to-witness-script-hash^BIP141 to:
- 2 <key1> <key2> 2 OP_CHECKMULTISIG
Where key1 is the numerically lesser of the two DER-encoded funding-pubkey and key2 is the greater.

Commitment Transaction

version: 2
locktime: upper 8 bits are 0x20, lower 24 bits are the lower 24 bits of the obscured commitment transaction 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 transaction number.
- txin[0] script bytes: 0
- txin[0] witness: 0 <signature-for-key1> <signature-for-key-2>

The 48-bit commitment transaction 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 which return funds to the owner of the commitment transaction (aka "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 time out 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, thus must be timelocked using OP_CSV. It can be claimed, without delay, by the other party if they know the revocation key. The output is a version 0 P2WSH, with a witness script:

OP_IF
    # Penalty transaction
    <revocation-pubkey>
OP_ELSE
    `to-self-delay`
    OP_CSV
    OP_DROP
    <local-delayedkey>
OP_ENDIF
OP_CHECKSIG

It 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, thus is a simple P2WPKH to remotekey.

Offered HTLC Outputs

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

<remotekey> OP_SWAP
    OP_SIZE 32 OP_EQUAL
OP_NOTIF
    # To me via HTLC-timeout transaction (timelocked) or to you with revocation key.
    OP_DROP 2 OP_SWAP <localkey> <revocationkey> 3 OP_CHECKMULTISIG
OP_ELSE
    # To you with preimage.
    OP_HASH160 <ripemd-of-payment-hash> OP_EQUALVERIFY
    OP_CHECKSIG
OP_ENDIF

The remote node can redeem the HTLC with the witness:

<remotesig> <payment-preimage>

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

0 <remote-sig> <revocation-sig> 0

The sending node can use the HTLC-timeout transaction to time out the HTLC once the HTLC is expired, as shown below.

Received HTLC Outputs

This output sends funds to the remote peer 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:

<remotekey> OP_SWAP
    OP_SIZE 32 OP_EQUAL
OP_IF
    # To me via HTLC-success transaction.
    OP_HASH160 <ripemd-of-payment-hash> OP_EQUALVERIFY
    2 OP_SWAP <localkey> 2 OP_CHECKMULTISIG
OP_ELSE
    OP_SIZE 0 OP_EQUAL
    OP_IF
        # To you after timeout.
        OP_DROP <locktime> OP_CHECKLOCKTIMEVERIFY OP_DROP
        OP_CHECKSIG
    OP_ELSE
        # To you if you have the revocation key  
        OP_SWAP 2 OP_SWAP <revocationkey> 2 OP_CHECKMULTISIG
    OP_ENDIF
OP_ENDIF

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

<remotesig> 0

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

0 <remote-sig> <revocation-sig>

To redeem the HTLC, the HTLC-success transaction is used as detailed below.

Trimmed Outputs

Each peer specifies dust-limit-satoshis below which outputs should not be produced; we term these outputs "trimmed". A trimmed output is considered too small to be worth creating, and thus that amount adds to the commitment transaction fee. For HTLCs, we need to take into account that the second-stage HTLC transaction may also be below the limit.

Requirements

The base fee must be subtracted from the to-local or to-remote outputs as specified in Fee Calculation before the commitment transaction outputs are determined.

If the amount of the commitment transaction to-local output would be less than dust-limit-satoshis set by the transaction owner, the commitment transaction MUST NOT contain that output, otherwise it 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, the commitment transaction MUST NOT contain that output, otherwise it 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, the commitment transaction MUST NOT contain that output, otherwise it 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, the commitment transaction MUST NOT contain that output, otherwise it 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. This is also the transaction which can be spent by a valid penalty transaction.

version: 2
locktime: 0 for HTLC-Success, htlc-timeout 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 <remotesig> <localsig> <payment-preimage> for HTLC-Success, 0 <remotesig> <localsig> 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
    <revocation-pubkey>
OP_ELSE
    `to-self-delay`
    OP_CSV
    OP_DROP
    <local-delayedkey>
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

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 weight 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 we use a simplified formula for expected weight, which assumes:

Signatures are 73 bytes long (the maximum length)
There is a small number of outputs (thus 1 byte to count them)
There is always both a to-local output and a to-remote output.

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

Commitment weight:   724 + 172 * num-untrimmed-htlc-outputs
HTLC-timeout weight: 669
HTLC-success weight: 718

Note that we refer 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:

Multiply feerate-per-kw by 669 and divide by 1000 (rounding down).

The fee for an HTLC-success transaction MUST BE calculated to match:

Multiply feerate-per-kw by 718 and divide by 1000 (rounding down).

The base fee for a commitment transaction MUST BE calculated to match:

Start with weight = 724.
For each committed HTLC, if that output is not trimmed as specified in Trimmed Outputs, add 172 to weight.
Multiply feerate-per-kw by weight, divide by 1000 (rounding down).

Example

For example, suppose that we have a feerate-per-kw of 5000, a dust-limit-satoshis of 546 satoshis, and commitment transaction with:

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

The HTLC timeout transaction weight is 669, thus fee would be 3345 satoshis. The HTLC success transaction weight is 718, thus fee would be 3590 satoshis

The commitment transaction weight would be calculated as follows:

weight starts at 724.
The offered HTLC of 5000 satoshis is above 546 + 3345 and would result in:
- an output of 5000 satoshi in the commitment transaction
- a HTLC timeout transaction of 5000 - 3345 satoshis which spends this output
- weight increases to 896
The offered HTLC of 1000 satoshis is below 546 + 3345, so would be trimmed.
The received HTLC of 7000 satoshis is above 546 + 3590 and would result in:
- an output of 7000 satoshi in the commitment transaction
- a HTLC success transaction of 7000 - 3590 satoshis which spends this output
- weight increases to 1068
The received HTLC of 800 satoshis is below 546 + 3590 so would be trimmed.

The base commitment transaction fee would be 5340 satoshi; the actual fee (adding the 1000 and 800 satoshi HTLCs which would have made dust outputs) is 7140 satoshi. The final fee may even be more if the to-local or to-remote outputs fall below dust-limit-satoshis.

Fee Payment

Base commimtment transaction fees will be extracted from the funder's amount, or if that is insufficient, will use the entire amount of the funder's output.

Note that if once fee amount is subtracted from the to-funder output, that output may be below dust-limit-satoshis and thus also contributes to fees.

A node MAY fail the channel if the resulting fee rate is too low.

Commitment Transaction Construction

This section ties the previous sections together to spell out the algorithm for constructing the commitment transaction for one peer, given that peer's dust-limit-satoshis, the current feerate-per-kw, amounts due to each peer (to-local and to-remote), and all committed HTLCs:

Initialize the commitment transaction input and locktime as specified in Commitment Transaction.
Calculate which committed HTLCs need to be trimmed (see Trimmed Outputs).
Calculate the base commitment transaction fee.
Subtract this base fee from the funder (either to-local or to-remote), with a floor of zero (see Fee Payment).
For every offered HTLC, if it is not trimmed, add an offered HTLC output.
For every received HTLC, if it is not trimmed, add an received HTLC output.
If the to-local amount is greater or equal to dust-limit-satoshis, add a To-Local Output.
If the to-remote amount is greater or equal to dust-limit-satoshis, add a To-Remote Output.
Sort the outputs into BIP 69 order

Keys

Key Derivation

Each commitment transaction uses a unique set of keys; localkey and remotekey. The HTLC-success and HTLC-timeout transactions use local-delayedkey and revocationkey. These are changed every time depending on the per-commitment-point.

Keys change because of the desire for trustless outsourcing of watching for revoked transactions; a watcher should not be able to determine what the contents of commitment transaction is, even if given the transaction ID to watch for and can make a resonable guess as to what HTLCs and balances might be included. Nonetheless, to avoid storage for every commitment transaction, it can be given the per-commitment-secret values (which can be stored compactly) and the revocation-basepoint and delayed-payment-basepoint to regnerate the scripts required for the penalty transaction: it need only be given (and store) the signatures for each penalty input.

Changing the localkey and remotekey every time ensures that commitment transaction id cannot be guessed: Every commitment transaction uses one of these in its output script. Splitting the local-delayedkey which is required for the penalty transaction allows that to be shared with the watcher without revealing localkey; 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-delayedkey or revocationkey with their bases.

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

`localkey`, `remotekey`, `local-delayedkey` and `remote-delayedkey` Derivation

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

pubkey = basepoint + SHA256(per-commitment-point || basepoint)*G

The localkey uses the local node's payment-basepoint, remotekey uses the remote node's payment-basepoint, the local-delayedkey uses the local node's delayed-payment-basepoint, and the remote-delayedkey uses the remote node's delayed-payment-basepoint.

The corresponding private keys can be derived similarly if the basepoint secrets are known (i.e., localkey and local-delayedkey only):

secretkey = basepoint-secret + SHA256(per-commitment-point || basepoint)

`revocationkey` Derivation

The revocationkey is a blinded key: the remote node provides the base, and the local node provides the blinding factor which it later reveals, so the remote node can use the secret revocationkey for a penalty transaction.

The per-commitment-point is generated using EC multiplication:

per-commitment-point = per-commitment-secret * G

And this is used to derive the revocation key from the remote node's revocation-basepoint:

revocationkey = 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:

revocationsecretkey = 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, and 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 then the index decremented.

The I'th secret P MUST match the output of this algorithm:

generate_from_seed(seed, I):
    P = seed
    for B in 0 to 47:
        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, or MAY calculate it 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. This is because given a secret on a 2^X boundary, we can derive all secrets up to the next 2^X boundary, and we always receive secrets 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 zeroes. You can derive the secret for any index which matches this prefix.

For example, secret 0xFFFFFFFFFFF0 allows us to derive secrets for 0xFFFFFFFFFFF1 through 0xFFFFFFFFFFFF inclusive. Secret 0xFFFFFFFFFF08 allows us to derive secrets 0xFFFFFFFFFF09 through 0xFFFFFFFFFF0F inclusive.

We do this 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 0 to bits:
        if B set in I:
            flip(B) in P
            P = SHA256(P)
    return P

We need only save one secret for each unique prefix; in effect we can count the number of trailing zeros, and that determines where in our storage array we store the secret:

# aka. count trailing zeroes
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

We also need to double-check that all previous secrets derive correctly, otherwise 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 as we traverse.
	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 we are asked to derive secret at index I, we need to figure out which known secret we can derive it from. The simplest method is iterating over all the known secrets, and testing if we can derive from it:

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 We haven't received index I yet.

This looks complicated, but remember that the index in entry b has b trailing zeros; the mask and compare is just seeing if the index at each bucket is a prefix of the index we want.

	- version: 4 bytes
	- witness_header <---- part of the witness data
	- count_tx_in: 1 byte
	- tx_in: 41 bytes
		commitment_input
	- count_tx_out: 1 byte
	- tx_out: 43
		htlc_output
	- lock_time: 4 bytes

Multiplying non-witness data by 4, this gives a weight of 376. Adding the witness data for each case (291 + 2 for HTLC-timeout, 340 + 2 for HTLC-success) gives a weight of:

669 (HTLC-timeout)
718 (HTLC-success)

Appendix C: Funding Transaction Test Vectors

In the following:

we assume 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)

The input for the funding transaction was created using a test chain with the following first two blocks, the second one with 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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

Appendix C: Commitment and HTLC Transaction Test Vectors

In the following:

we consider local transactions, which implies that all payments to local are delayed
we assume 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)

We start by defining common basic parameters for each test vector: 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; we specifically corrupt an entry and all its children (except for the last test, which would require another 8 samples to be detected). For these tests we use a seed of 0xFFF...FF and incorrect entries are seeded with 0x000...00.
