This only matters because the same ordering is used to send 64 `htlc_signatures` and the HTLC transactions themselves are different, thus the 65 two peers must agree on the canonical ordering for this case. 66 67 ## Use of Segwit 68 69 Most transaction outputs used here are pay-to-witness-script-hash<sup>[BIP141](https://github.com/bitcoin/bips/blob/master/bip-0141.mediawiki#witness-program)</sup> (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. 70 71 A `<>` designates an empty vector as required for compliance with MINIMALIF-standard rule.<sup>[MINIMALIF](https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2016-August/013014.html)</sup> 72 73 ## Funding Transaction Output 74 75 * The funding output script is a P2WSH to: 76 77 `2 <pubkey1> <pubkey2> 2 OP_CHECKMULTISIG` 78 79 * Where `pubkey1` is the lexicographically lesser of the two `funding_pubkey` in compressed format, and where `pubkey2` is the lexicographically greater of the two. 80 81 ## Commitment Transaction 82 83 * version: 2 84 * locktime: upper 8 bits are 0x20, lower 24 bits are the lower 24 bits of the obscured commitment number 85 * txin count: 1 86 * `txin[0]` outpoint: `txid` and `output_index` from `funding_created` message 87 * `txin[0]` sequence: upper 8 bits are 0x80, lower 24 bits are upper 24 bits of the obscured commitment number 88 * `txin[0]` script bytes: 0 89 * `txin[0]` witness: `0 <signature_for_pubkey1> <signature_for_pubkey2>` 90 91 The 48-bit commitment number is obscured by `XOR` with the lower 48 bits of: 92 93 SHA256(payment_basepoint from open_channel || payment_basepoint from accept_channel) 94 95 This obscures the number of commitments made on the channel in the 96 case of unilateral close, yet still provides a useful index for both 97 nodes (who know the `payment_basepoint`s) to quickly find a revoked 98 commitment transaction. 99 100 ### Commitment Transaction Outputs 101 102 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. For HTLCs 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). 103 104 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. 105 Otherwise, the required minimum timeout on HTLCs is lengthened by this delay, causing longer timeouts for HTLCs traversing the network. 106 107 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). 108 109 #### `to_local` Output 110 111 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: 112 113 OP_IF 114 # Penalty transaction 115 <revocationpubkey> 116 OP_ELSE 117 `to_self_delay` 118 OP_CHECKSEQUENCEVERIFY 119 OP_DROP 120 <local_delayedpubkey> 121 OP_ENDIF 122 OP_CHECKSIG 123 124 The output is spent by an input with `nSequence` field set to `to_self_delay` (which can only be valid after that duration has passed) and witness: 125 126 <local_delayedsig> <> 127 128 If a revoked commitment transaction is published, the other party can spend this output immediately with the following witness: 129 130 <revocation_sig> 1 131 132 #### `to_remote` Output 133 134 If `option_anchors` applies to the commitment transaction, the `to_remote` output is encumbered by a one block csv lock. 135 136 <remotepubkey> OP_CHECKSIGVERIFY 1 OP_CHECKSEQUENCEVERIFY 137 138 The output is spent by an input with `nSequence` field set to `1` and witness: 139 140 <remote_sig> 141 142 Otherwise, this output is a simple P2WPKH to `remotepubkey`. 143 144 #### `to_local_anchor` and `to_remote_anchor` Output (option_anchors) 145 146 This output can be spent by the local and remote nodes respectively to provide incentive to mine the transaction, using child-pays-for-parent. Both 147 anchor outputs are always added, except for the case where there are no htlcs and one of the parties has a commitment output that is below the dust limit. 148 In that case only an anchor is added for the commitment output that does materialize. This typically happens if the initiator closes right after opening 149 (no `to_remote` output). 150 151 <local_funding_pubkey/remote_funding_pubkey> OP_CHECKSIG OP_IFDUP 152 OP_NOTIF 153 OP_16 OP_CHECKSEQUENCEVERIFY 154 OP_ENDIF 155 156 Each party has its own anchor output that locks to their funding key. This is to prevent a malicious peer from attaching child transactions with a low fee 157 density to an anchor and thereby blocking the victim from getting the commit tx confirmed in time. This defense is supported by a change in Bitcoin core 0.19: 158 https://github.com/bitcoin/bitcoin/pull/15681. This is also the reason that every non-anchor output on the commit tx is CSV locked. 159 160 To prevent utxo set pollution, any anchor that remains unspent can be spent by anyone after the commitment tx confirms. This is also the reason to lock 161 the anchor outputs to the funding key. Third parties can observe this key and reconstruct the spend script, even if none of the commitment outputs would 162 be spent. This does assume that at some point the fee market goes down to a level where sweeping the anchors is economical. 163 164 The amount of the output is fixed at 330 sats, the default dust limit for P2WSH. 165 166 Spending of the output requires the following witness: 167 168 <local_sig/remote_sig> 169 170 After 16 blocks, anyone can sweep the anchor with witness: 171 172 <> 173 174 #### Offered HTLC Outputs 175 176 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 (no option_anchors): 177 178 # To remote node with revocation key 179 OP_DUP OP_HASH160 <RIPEMD160(SHA256(revocationpubkey))> OP_EQUAL 180 OP_IF 181 OP_CHECKSIG 182 OP_ELSE 183 <remote_htlcpubkey> OP_SWAP OP_SIZE 32 OP_EQUAL 184 OP_NOTIF 185 # To local node via HTLC-timeout transaction (timelocked). 186 OP_DROP 2 OP_SWAP <local_htlcpubkey> 2 OP_CHECKMULTISIG 187 OP_ELSE 188 # To remote node with preimage. 189 OP_HASH160 <RIPEMD160(payment_hash)> OP_EQUALVERIFY 190 OP_CHECKSIG 191 OP_ENDIF 192 OP_ENDIF 193 194 Or, with `option_anchors`: 195 196 # To remote node with revocation key 197 OP_DUP OP_HASH160 <RIPEMD160(SHA256(revocationpubkey))> OP_EQUAL 198 OP_IF 199 OP_CHECKSIG 200 OP_ELSE 201 <remote_htlcpubkey> OP_SWAP OP_SIZE 32 OP_EQUAL 202 OP_NOTIF 203 # To local node via HTLC-timeout transaction (timelocked). 204 OP_DROP 2 OP_SWAP <local_htlcpubkey> 2 OP_CHECKMULTISIG 205 OP_ELSE 206 # To remote node with preimage. 207 OP_HASH160 <RIPEMD160(payment_hash)> OP_EQUALVERIFY 208 OP_CHECKSIG 209 OP_ENDIF 210 1 OP_CHECKSEQUENCEVERIFY OP_DROP 211 OP_ENDIF 212 213 The remote node can redeem the HTLC with the witness: 214 215 <remotehtlcsig> <payment_preimage> 216 217 Note that if `option_anchors` applies, the nSequence field of 218 the spending input must be `1`. 219 220 If a revoked commitment transaction is published, the remote node can spend this output immediately with the following witness: 221 222 <revocation_sig> <revocationpubkey> 223 224 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. 225 226 #### Received HTLC Outputs 227 228 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 (no `option_anchors`): 229 230 # To remote node with revocation key 231 OP_DUP OP_HASH160 <RIPEMD160(SHA256(revocationpubkey))> OP_EQUAL 232 OP_IF 233 OP_CHECKSIG 234 OP_ELSE 235 <remote_htlcpubkey> OP_SWAP OP_SIZE 32 OP_EQUAL 236 OP_IF 237 # To local node via HTLC-success transaction. 238 OP_HASH160 <RIPEMD160(payment_hash)> OP_EQUALVERIFY 239 2 OP_SWAP <local_htlcpubkey> 2 OP_CHECKMULTISIG 240 OP_ELSE 241 # To remote node after timeout. 242 OP_DROP <cltv_expiry> OP_CHECKLOCKTIMEVERIFY OP_DROP 243 OP_CHECKSIG 244 OP_ENDIF 245 OP_ENDIF 246 247 Or, with `option_anchors`: 248 249 # To remote node with revocation key 250 OP_DUP OP_HASH160 <RIPEMD160(SHA256(revocationpubkey))> OP_EQUAL 251 OP_IF 252 OP_CHECKSIG 253 OP_ELSE 254 <remote_htlcpubkey> OP_SWAP OP_SIZE 32 OP_EQUAL 255 OP_IF 256 # To local node via HTLC-success transaction. 257 OP_HASH160 <RIPEMD160(payment_hash)> OP_EQUALVERIFY 258 2 OP_SWAP <local_htlcpubkey> 2 OP_CHECKMULTISIG 259 OP_ELSE 260 # To remote node after timeout. 261 OP_DROP <cltv_expiry> OP_CHECKLOCKTIMEVERIFY OP_DROP 262 OP_CHECKSIG 263 OP_ENDIF 264 1 OP_CHECKSEQUENCEVERIFY OP_DROP 265 OP_ENDIF 266 267 To timeout the HTLC, the remote node spends it with the witness: 268 269 <remotehtlcsig> <> 270 271 Note that if `option_anchors` applies, the nSequence field of 272 the spending input must be `1`. 273 274 If a revoked commitment transaction is published, the remote node can spend this output immediately with the following witness: 275 276 <revocation_sig> <revocationpubkey> 277 278 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. 279 280 ### Trimmed Outputs 281 282 Each peer specifies a `dust_limit_satoshis` below which outputs should 283 not be produced; these outputs that are not produced are termed "trimmed". A trimmed output is 284 considered too small to be worth creating and is instead added 285 to the commitment transaction fee. For HTLCs, it needs to be taken into 286 account that the second-stage HTLC transaction may also be below the 287 limit. 288 289 #### Requirements 290 291 The base fee and anchor output values: 292 - before the commitment transaction outputs are determined: 293 - MUST be subtracted from the `to_local` or `to_remote` 294 outputs, as specified in [Fee Calculation](#fee-calculation). 295 296 The commitment transaction: 297 - if the amount of the commitment transaction `to_local` output would be 298 less than `dust_limit_satoshis` set by the transaction owner: 299 - MUST NOT contain that output. 300 - otherwise: 301 - MUST be generated as specified in [`to_local` Output](#to_local-output). 302 - if the amount of the commitment transaction `to_remote` output would be 303 less than `dust_limit_satoshis` set by the transaction owner: 304 - MUST NOT contain that output. 305 - otherwise: 306 - MUST be generated as specified in [`to_remote` Output](#to_remote-output). 307 - for every offered HTLC: 308 - if the HTLC amount minus the HTLC-timeout fee would be less than 309 `dust_limit_satoshis` set by the transaction owner: 310 - MUST NOT contain that output. 311 - otherwise: 312 - MUST be generated as specified in 313 [Offered HTLC Outputs](#offered-htlc-outputs). 314 - for every received HTLC: 315 - if the HTLC amount minus the HTLC-success fee would be less than 316 `dust_limit_satoshis` set by the transaction owner: 317 - MUST NOT contain that output. 318 - otherwise: 319 - MUST be generated as specified in 320 [Received HTLC Outputs](#received-htlc-outputs). 321 322 ## HTLC-Timeout and HTLC-Success Transactions 323 324 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. 325 326 * version: 2 327 * locktime: `0` for HTLC-success, `cltv_expiry` for HTLC-timeout 328 * txin count: 1 329 * `txin[0]` outpoint: `txid` of the commitment transaction and `output_index` of the matching HTLC output for the HTLC transaction 330 * `txin[0]` sequence: `0` (set to `1` for `option_anchors`) 331 * `txin[0]` script bytes: `0` 332 * `txin[0]` witness stack: `0 <remotehtlcsig> <localhtlcsig> <payment_preimage>` for HTLC-success, `0 <remotehtlcsig> <localhtlcsig> <>` for HTLC-timeout 333 * txout count: 1 334 * `txout[0]` amount: the HTLC `amount_msat` divided by 1000 (rounding down) minus fees in satoshis (see [Fee Calculation](#fee-calculation)) 335 * `txout[0]` script: version-0 P2WSH with witness script as shown below 336 * if `option_anchors` applies to this commitment transaction, `SIGHASH_SINGLE|SIGHASH_ANYONECANPAY` is used as described in [BOLT #5](05-onchain.md#generation-of-htlc-transactions). 337 338 The witness script for the output is: 339 340 OP_IF 341 # Penalty transaction 342 <revocationpubkey> 343 OP_ELSE 344 `to_self_delay` 345 OP_CHECKSEQUENCEVERIFY 346 OP_DROP 347 <local_delayedpubkey> 348 OP_ENDIF 349 OP_CHECKSIG 350 351 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`. 352 353 ## Legacy Closing Transaction 354 355 This variant is used for `closing_signed` messages (i.e. where `option_simple_close` is not negotiated). 356 357 Note that there are two possible variants for each node. 358 359 * version: 2 360 * locktime: 0 361 * txin count: 1 362 * `txin[0]` outpoint: `txid` and `output_index` from `funding_created` message 363 * `txin[0]` sequence: 0xFFFFFFFF 364 * `txin[0]` script bytes: 0 365 * `txin[0]` witness: `0 <signature_for_pubkey1> <signature_for_pubkey2>` 366 * txout count: 1 or 2 367 * `txout` amount: final balance to be paid to one node (minus `fee_satoshis` from `closing_signed`, if this peer funded the channel) 368 * `txout` script: as specified in that node's `scriptpubkey` in its `shutdown` message 369 370 ### Requirements 371 372 Each node offering a signature: 373 - MUST round each output down to whole satoshis. 374 - MUST subtract the fee given by `fee_satoshis` from the output to the funder. 375 - MUST remove any output below its own `dust_limit_satoshis`. 376 - MAY eliminate its own output. 377 378 ### Rationale 379 380 There is a possibility of irreparable differences on closing if one 381 node considers the other's output too small to allow propagation on 382 the Bitcoin network (a.k.a. "dust"), and that other node instead 383 considers that output too valuable to discard. This is why each 384 side uses its own `dust_limit_satoshis`, and the result can be a 385 signature validation failure, if they disagree on what the closing 386 transaction should look like. 387 388 However, if one side chooses to eliminate its own output, there's no 389 reason for the other side to fail the closing protocol; so this is 390 explicitly allowed. The signature indicates which variant 391 has been used. 392 393 There will be at least one output, if the funding amount is greater 394 than twice `dust_limit_satoshis`. 395 396 ## Closing Transaction 397 398 This variant is used for `closing_complete` and `closing_sig` messages (i.e. where `option_simple_close` is negotiated). 399 400 In this case, the node sending `closing_complete` ("the closer") pays the fees. 401 The outputs are ordered as detailed in [Transaction Output Ordering](#transaction-output-ordering). 402 403 The side with lesser funds can opt to omit their own output. 404 405 * version: 2 406 * locktime: `locktime` from the `closing_complete` message 407 * txin count: 1 408 * `txin[0]` outpoint: `txid` and `output_index` of the channel output 409 * `txin[0]` sequence: 0xFFFFFFFD 410 * `txin[0]` script bytes: 0 411 * `txin[0]` witness: `0 <signature_for_pubkey1> <signature_for_pubkey2>` 412 * txout count: 1 or 2 413 * The closer output: 414 * `txout` amount: 415 * 0 if the `scriptpubkey` starts with `OP_RETURN` 416 * otherwise the final balance for the closer, minus `closing_complete.fee_satoshis`, rounded down to whole satoshis 417 * `txout` script: as specified in `closer_scriptpubkey` from the `closing_complete` message 418 * The closee output: 419 * `txout` amount: 420 * 0 if the `scriptpubkey` starts with `OP_RETURN` 421 * otherwise the final balance for the closee, rounded down to whole satoshis 422 * `txout` script: as specified in `closee_scriptpubkey` from the `closing_complete` message 423 424 ### Requirements 425 426 Each node offering a signature: 427 - MUST round each output down to whole satoshis. 428 - MUST subtract the fee given by `fee_satoshis` from the closer output. 429 - MUST set the output amount to 0 if the `scriptpubkey` is `OP_RETURN`. 430 431 ## Fees 432 433 ### Fee Calculation 434 435 The fee calculation for both commitment transactions and HTLC 436 transactions is based on the current `feerate_per_kw` and the 437 *expected weight* of the transaction. 438 439 The actual and expected weights vary for several reasons: 440 441 * Bitcoin uses DER-encoded signatures, which vary in size. 442 * Bitcoin also uses variable-length integers, so a large number of outputs will take 3 bytes to encode rather than 1. 443 * The `to_remote` output may be below the dust limit. 444 * The `to_local` output may be below the dust limit once fees are extracted. 445 446 Thus, a simplified formula for *expected weight* is used, which assumes: 447 448 * Signatures are 73 bytes long (the maximum length). 449 * There are a small number of outputs (thus 1 byte to count them). 450 * There are always both a `to_local` output and a `to_remote` output. 451 * (if `option_anchors`) there are always both a `to_local_anchor` and `to_remote_anchor` output. 452 453 This yields the following *expected weights* (details of the computation in [Appendix A](#appendix-a-expected-weights)): 454 455 Commitment weight (no option_anchors): 724 + 172 * num-untrimmed-htlc-outputs 456 Commitment weight (option_anchors): 1124 + 172 * num-untrimmed-htlc-outputs 457 HTLC-timeout weight (no option_anchors): 663 458 HTLC-timeout weight (option_anchors): 666 459 HTLC-success weight (no option_anchors): 703 460 HTLC-success weight (option_anchors): 706 461 462 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. 463 464 #### Requirements 465 466 The fee for an HTLC-timeout transaction: 467 - If `option_anchors` applies: 468 1. MUST be 0. 469 - Otherwise, MUST be calculated to match: 470 1. Multiply `feerate_per_kw` by 663 and divide by 1000 (rounding down). 471 472 The fee for an HTLC-success transaction: 473 - If `option_anchors` applies: 474 1. MUST be 0. 475 - Otherwise, MUST be calculated to match: 476 1. Multiply `feerate_per_kw` by 703 and divide by 1000 (rounding down). 477 478 The base fee for a commitment transaction: 479 - MUST be calculated to match: 480 1. Start with `weight` = 724 (1124 if `option_anchors` applies). 481 2. For each committed HTLC, if that output is not trimmed as specified in 482 [Trimmed Outputs](#trimmed-outputs), add 172 to `weight`. 483 3. Multiply `feerate_per_kw` by `weight`, divide by 1000 (rounding down). 484 485 #### Example 486 487 For example, suppose there is a `feerate_per_kw` of 5000, a `dust_limit_satoshis` of 546 satoshis, and a commitment transaction with: 488 * two offered HTLCs of 5000000 and 1000000 millisatoshis (5000 and 1000 satoshis) 489 * two received HTLCs of 7000000 and 800000 millisatoshis (7000 and 800 satoshis) 490 491 The HTLC-timeout transaction `weight` is 663, and thus the fee is 3315 satoshis. 492 The HTLC-success transaction `weight` is 703, and thus the fee is 3515 satoshis 493 494 The commitment transaction `weight` is calculated as follows: 495 496 * `weight` starts at 724. 497 498 * The offered HTLC of 5000 satoshis is above 546 + 3315 and results in: 499 * an output of 5000 satoshi in the commitment transaction 500 * an HTLC-timeout transaction of 5000 - 3315 satoshis that spends this output 501 * `weight` increases to 896 502 503 * The offered HTLC of 1000 satoshis is below 546 + 3315 so it is trimmed. 504 505 * The received HTLC of 7000 satoshis is above 546 + 3515 and results in: 506 * an output of 7000 satoshi in the commitment transaction 507 * an HTLC-success transaction of 7000 - 3515 satoshis that spends this output 508 * `weight` increases to 1068 509 510 * The received HTLC of 800 satoshis is below 546 + 3515 so it is trimmed. 511 512 The base commitment transaction fee is 5340 satoshi; the actual 513 fee (which adds the 1000 and 800 satoshi HTLCs that would make dust 514 outputs) is 7140 satoshi. The final fee may be even higher if the 515 `to_local` or `to_remote` outputs fall below `dust_limit_satoshis`. 516 517 ### Fee Payment 518 519 Base commitment transaction fees and amounts for `to_local_anchor` and `to_remote_anchor` outputs are extracted from the funder's amount; 520 Restrictions to the commitment tx output for the funder in relation to the 521 channel reserve apply as described in [BOLT #2](02-peer-protocol.md). 522 523 Note that after the fee amount is subtracted from the to-funder output, 524 that output may be below `dust_limit_satoshis`, and thus will also 525 contribute to fees. 526 527 A node: 528 - if the resulting fee rate is too low: 529 - MAY send a `warning` and close the connection, or send an 530 `error` and fail the channel. 531 532 ### Calculating Fees for Collaborative Transactions 533 534 For transactions constructed using the [interactive protocol](02-peer-protocol.md#interactive-transaction-construction), 535 fees are paid by each party to the transaction, at a `feerate` determined during the 536 initiation, with the initiator covering the fees for the common transaction fields. 537 538 ## Dust Limits 539 540 The `dust_limit_satoshis` parameter is used to configure the threshold below 541 which nodes will not produce on-chain transaction outputs. 542 543 There is no consensus rule in Bitcoin that makes outputs below dust thresholds 544 invalid or unspendable, but policy rules in popular implementations will prevent 545 relaying transactions that contain such outputs. 546 547 Bitcoin Core defines the following dust thresholds: 548 549 - pay to pubkey hash (p2pkh): 546 satoshis 550 - pay to script hash (p2sh): 540 satoshis 551 - pay to witness pubkey hash (p2wpkh): 294 satoshis 552 - pay to witness script hash (p2wsh): 330 satoshis 553 - unknown segwit versions: 354 satoshis 554 - `OP_RETURN` outputs: these are never dust 555 556 The rationale of this calculation (implemented [here](https://github.com/bitcoin/bitcoin/blob/2aff9a36c352640a263e8b5de469710f7e80eb54/src/policy/policy.cpp#L28)) 557 is explained in the following sections. 558 559 In all these sections, the calculations are done with a feerate of 3000 sat/kB 560 as per Bitcoin Core's implementation. 561 562 ### Pay to pubkey hash (p2pkh) 563 564 A p2pkh output is 34 bytes: 565 566 - 8 bytes for the output amount 567 - 1 byte for the script length 568 - 25 bytes for the script (`OP_DUP` `OP_HASH160` `20` 20-bytes `OP_EQUALVERIFY` `OP_CHECKSIG`) 569 570 A p2pkh input is at least 148 bytes: 571 572 - 36 bytes for the previous output (32 bytes hash + 4 bytes index) 573 - 4 bytes for the sequence 574 - 1 byte for the script sig length 575 - 107 bytes for the script sig: 576 - 1 byte for the items count 577 - 1 byte for the signature length 578 - 71 bytes for the signature 579 - 1 byte for the public key length 580 - 33 bytes for the public key 581 582 The p2pkh dust threshold is then `(34 + 148) * 3000 / 1000 = 546 satoshis` 583 584 ### Pay to script hash (p2sh) 585 586 A p2sh output is 32 bytes: 587 588 - 8 bytes for the output amount 589 - 1 byte for the script length 590 - 23 bytes for the script (`OP_HASH160` `20` 20-bytes `OP_EQUAL`) 591 592 A p2sh input doesn't have a fixed size, since it depends on the underlying 593 script, so we use 148 bytes as a lower bound. 594 595 The p2sh dust threshold is then `(32 + 148) * 3000 / 1000 = 540 satoshis` 596 597 ### Pay to witness pubkey hash (p2wpkh) 598 599 A p2wpkh output is 31 bytes: 600 601 - 8 bytes for the output amount 602 - 1 byte for the script length 603 - 22 bytes for the script (`OP_0` `20` 20-bytes) 604 605 A p2wpkh input is at least 67 bytes (depending on the signature length): 606 607 - 36 bytes for the previous output (32 bytes hash + 4 bytes index) 608 - 4 bytes for the sequence 609 - 1 byte for the script sig length 610 - 26 bytes for the witness (rounded down from 26.75, with the 75% segwit discount applied): 611 - 1 byte for the items count 612 - 1 byte for the signature length 613 - 71 bytes for the signature 614 - 1 byte for the public key length 615 - 33 bytes for the public key 616 617 The p2wpkh dust threshold is then `(31 + 67) * 3000 / 1000 = 294 satoshis` 618 619 ### Pay to witness script hash (p2wsh) 620 621 A p2wsh output is 43 bytes: 622 623 - 8 bytes for the output amount 624 - 1 byte for the script length 625 - 34 bytes for the script (`OP_0` `32` 32-bytes) 626 627 A p2wsh input doesn't have a fixed size, since it depends on the underlying 628 script, so we use 67 bytes as a lower bound. 629 630 The p2wsh dust threshold is then `(43 + 67) * 3000 / 1000 = 330 satoshis` 631 632 ### Unknown segwit versions 633 634 Unknown segwit outputs are at most 51 bytes: 635 636 - 8 bytes for the output amount 637 - 1 byte for the script length 638 - 42 bytes for the script (`OP_1` through `OP_16` inclusive, followed by a single push of 2 to 40 bytes) 639 640 The input doesn't have a fixed size, since it depends on the underlying 641 script, so we use 67 bytes as a lower bound. 642 643 The unknown segwit version dust threshold is then `(51 + 67) * 3000 / 1000 = 354 satoshis` 644 645 ## Commitment Transaction Construction 646 647 This section ties the previous sections together to detail the 648 algorithm for constructing the commitment transaction for one peer: 649 given that peer's `dust_limit_satoshis`, the current `feerate_per_kw`, 650 the amounts due to each peer (`to_local` and `to_remote`), and all 651 committed HTLCs: 652 653 1. Initialize the commitment transaction input and locktime, as specified 654 in [Commitment Transaction](#commitment-transaction). 655 1. Calculate which committed HTLCs need to be trimmed (see [Trimmed Outputs](#trimmed-outputs)). 656 2. Calculate the base [commitment transaction fee](#fee-calculation). 657 3. Subtract this base fee from the funder (either `to_local` or `to_remote`). 658 If `option_anchors` applies to the commitment transaction, 659 also subtract two times the fixed anchor size of 330 sats from the funder 660 (either `to_local` or `to_remote`). 661 4. For every offered HTLC, if it is not trimmed, add an 662 [offered HTLC output](#offered-htlc-outputs). 663 5. For every received HTLC, if it is not trimmed, add an 664 [received HTLC output](#received-htlc-outputs). 665 6. If the `to_local` amount is greater or equal to `dust_limit_satoshis`, 666 add a [`to_local` output](#to_local-output). 667 7. If the `to_remote` amount is greater or equal to `dust_limit_satoshis`, 668 add a [`to_remote` output](#to_remote-output). 669 8. If `option_anchors` applies to the commitment transaction: 670 * if `to_local` exists or there are untrimmed HTLCs, add a [`to_local_anchor` output](#to_local_anchor-and-to_remote_anchor-output-option_anchors) 671 * if `to_remote` exists or there are untrimmed HTLCs, add a [`to_remote_anchor` output](#to_local_anchor-and-to_remote_anchor-output-option_anchors) 672 9. Sort the outputs into [BIP 69+CLTV order](#transaction-output-ordering). 673 674 # Keys 675 676 ## Key Derivation 677 678 Each commitment transaction uses a unique `localpubkey`. 679 The HTLC-success and HTLC-timeout transactions use `local_delayedpubkey` and `revocationpubkey`. 680 These are changed for every transaction based on the `per_commitment_point`. 681 682 The reason for key change is so that trustless watching for revoked 683 transactions can be outsourced. Such a _watcher_ should not be able to 684 determine the contents of a commitment transaction — even if the _watcher_ knows 685 which transaction ID to watch for and can make a reasonable guess 686 as to which HTLCs and balances may be included. Nonetheless, to 687 avoid storage of every commitment transaction, a _watcher_ can be given the 688 `per_commitment_secret` values (which can be stored compactly) and the 689 `revocation_basepoint` and `delayed_payment_basepoint` used to regenerate 690 the scripts required for the penalty transaction; thus, a _watcher_ need only be 691 given (and store) the signatures for each penalty input. 692 693 Changing the `localpubkey` every time ensures that commitment 694 transaction ID cannot be guessed except in the trivial case where there is no 695 `to_local` output, as every commitment transaction uses an ID 696 in its output script. Splitting the `local_delayedpubkey`, which is required for 697 the penalty transaction, allows it to be shared with the _watcher_ without 698 revealing `localpubkey`; even if both peers use the same _watcher_, nothing is revealed. 699 700 Finally, even in the case of normal unilateral close, the HTLC-success 701 and/or HTLC-timeout transactions do not reveal anything to the 702 _watcher_, as it does not know the corresponding `per_commitment_secret` and 703 cannot relate the `local_delayedpubkey` or `revocationpubkey` with their bases. 704 705 For efficiency, keys are generated from a series of per-commitment secrets 706 that are generated from a single seed, which allows the receiver to compactly 707 store them (see [below](#efficient-per-commitment-secret-storage)). 708 709 ### `localpubkey`, `local_htlcpubkey`, `remote_htlcpubkey`, `local_delayedpubkey`, and `remote_delayedpubkey` Derivation 710 711 These pubkeys are simply generated by addition from their base points: 712 713 pubkey = basepoint + SHA256(per_commitment_point || basepoint) * G 714 715 - The `localpubkey` uses the local node's `payment_basepoint`; 716 - The `local_htlcpubkey` uses the local node's `htlc_basepoint`; 717 - The `remote_htlcpubkey` uses the remote node's `htlc_basepoint`; 718 - The `local_delayedpubkey` uses the local node's `delayed_payment_basepoint`; 719 - The `remote_delayedpubkey` uses the remote node's `delayed_payment_basepoint`. 720 721 The corresponding private keys can be similarly derived, if the basepoint 722 secrets are known (i.e. the private keys corresponding to `localpubkey`, `local_htlcpubkey`, and `local_delayedpubkey` only): 723 724 privkey = basepoint_secret + SHA256(per_commitment_point || basepoint) 725 726 ### `remotepubkey` Derivation 727 728 The `remotepubkey` is simply the remote node's `payment_basepoint`. 729 730 This means that a node can spend a commitment 731 transaction even if it has lost data and doesn't know the 732 corresponding `per_commitment_point`. A watchtower could correlate 733 transactions given to it which only have a `to_remote` output if it 734 sees one of them onchain, but such transactions do not need any 735 enforcement and should not be handed to a watchtower. 736 737 ### `revocationpubkey` Derivation 738 739 The `revocationpubkey` is a blinded key: when the local node wishes to create a new 740 commitment for the remote node, it uses its own `revocation_basepoint` and the remote 741 node's `per_commitment_point` to derive a new `revocationpubkey` for the 742 commitment. After the remote node reveals the 743 `per_commitment_secret` used (thereby revoking that commitment), the local node 744 can then derive the `revocationprivkey`, as it now knows the two secrets 745 necessary to derive the key (`revocation_basepoint_secret` and 746 `per_commitment_secret`). 747 748 The `per_commitment_point` is generated using elliptic-curve multiplication: 749 750 per_commitment_point = per_commitment_secret * G 751 752 And this is used to derive the revocation pubkey from the remote node's 753 `revocation_basepoint`: 754 755 revocationpubkey = revocation_basepoint * SHA256(revocation_basepoint || per_commitment_point) + per_commitment_point * SHA256(per_commitment_point || revocation_basepoint) 756 757 This construction ensures that neither the node providing the 758 basepoint nor the node providing the `per_commitment_point` can know the 759 private key without the other node's secret. 760 761 The corresponding private key can be derived once the `per_commitment_secret` 762 is known: 763 764 revocationprivkey = revocation_basepoint_secret * SHA256(revocation_basepoint || per_commitment_point) + per_commitment_secret * SHA256(per_commitment_point || revocation_basepoint) 765 766 ### Per-commitment Secret Requirements 767 768 A node: 769 - MUST select an unguessable 256-bit seed for each connection, 770 - MUST NOT reveal the seed. 771 772 Up to (2^48 - 1) per-commitment secrets can be generated. 773 774 The first secret used: 775 - MUST be index 281474976710655, 776 - and from there, the index is decremented. 777 778 The I'th secret P: 779 - MUST match the output of this algorithm: 780 ``` 781 generate_from_seed(seed, I): 782 P = seed 783 for B in 47 down to 0: 784 if B set in I: 785 flip(B) in P 786 P = SHA256(P) 787 return P 788 ``` 789 790 Where "flip(B)" alternates the (B mod 8) bit of the (B div 8) 791 byte of the value. So, "flip(0) in e3b0..." is "e2b0...", and 792 "flip(10) in "e3b0..." is "e3b4...". 793 794 The receiving node: 795 - MAY store all previous per-commitment secrets. 796 - MAY calculate them from a compact representation, as described below. 797 798 ## Efficient Per-commitment Secret Storage 799 800 The receiver of a series of secrets can store them compactly in an 801 array of 49 (value,index) pairs. Because, for a given secret on a 802 2^X boundary, all secrets up to the next 2^X boundary can be derived; 803 and secrets are always received in descending order starting at 804 `0xFFFFFFFFFFFF`. 805 806 In binary, it's helpful to think of any index in terms of a *prefix*, 807 followed by some trailing 0s. You can derive the secret for any 808 index that matches this *prefix*. 809 810 For example, secret `0xFFFFFFFFFFF0` allows the secrets to be derived for 811 `0xFFFFFFFFFFF1` through `0xFFFFFFFFFFFF`, inclusive; and secret `0xFFFFFFFFFF08` 812 allows the secrets to be derived for `0xFFFFFFFFFF09` through `0xFFFFFFFFFF0F`, 813 inclusive. 814 815 This is done using a slight generalization of `generate_from_seed` above: 816 817 # Return I'th secret given base secret whose index has bits..47 the same. 818 derive_secret(base, bits, I): 819 P = base 820 for B in bits - 1 down to 0: 821 if B set in I: 822 flip(B) in P 823 P = SHA256(P) 824 return P 825 826 Only one secret for each unique prefix need be saved; in effect, the number of 827 trailing 0s is counted, and this determines where in the storage array the 828 secret is stored: 829 830 # a.k.a. count trailing 0s 831 where_to_put_secret(I): 832 for B in 0 to 47: 833 if testbit(I) in B == 1: 834 return B 835 # I = 0, this is the seed. 836 return 48 837 838 A double-check, that all previous secrets derive correctly, is needed; 839 if this check fails, the secrets were not generated from the same seed: 840 841 insert_secret(secret, I): 842 B = where_to_put_secret(I) 843 844 # This tracks the index of the secret in each bucket across the traversal. 845 for b in 0 to B: 846 if derive_secret(secret, B, known[b].index) != known[b].secret: 847 error The secret for I is incorrect 848 return 849 850 # Assuming this automatically extends known[] as required. 851 known[B].index = I 852 known[B].secret = secret 853 854 Finally, if an unknown secret at index `I` needs be derived, it must be 855 discovered which known secret can be used to derive it. The simplest 856 method is iterating over all the known secrets, and testing if each 857 can be used to derive the unknown secret: 858 859 derive_old_secret(I): 860 for b in 0 to len(secrets): 861 # Mask off the non-zero prefix of the index. 862 MASK = ~((1 << b) - 1) 863 if (I & MASK) == secrets[b].index: 864 return derive_secret(known, i, I) 865 error Index 'I' hasn't been received yet. 866 867 This looks complicated, but remember that the index in entry `b` has 868 `b` trailing 0s; the mask and compare simply checks if the index 869 at each bucket is a prefix of the desired index. 870 871 # Appendix A: Expected Weights 872 873 ## Expected Weight of the Funding Transaction (v2 Channel Establishment) 874 875 The *expected weight* of a funding transaction is calculated as follows: 876 877 inputs: 41 bytes 878 - previous_out_point: 36 bytes 879 - hash: 32 bytes 880 - index: 4 bytes 881 - var_int: 1 byte 882 - script_sig: 0 bytes 883 - witness <---- Cost for "witness" data calculated separately. 884 - sequence: 4 bytes 885 886 non_funding_outputs: 9 bytes + `scriptlen` 887 - value: 8 bytes 888 - var_int: 1 byte <---- assuming a standard output script 889 - script: `scriptlen` 890 891 funding_output: 43 bytes 892 - value: 8 bytes 893 - var_int: 1 byte 894 - script: 34 bytes 895 - OP_0: 1 byte 896 - PUSHDATA(32-byte-hash): 33 bytes 897 898 Multiplying non-witness data by 4 results in a weight of: 899 900 // transaction_fields = 10 (version, input count, output count, locktime) 901 // segwit_fields = 2 (marker + flag) 902 // funding_transaction = 43 + num_inputs * 41 + num_outputs * 9 + sum(scriptlen) 903 funding_transaction_weight = 4 * (funding_transaction + transaction_fields) + segwit_fields 904 905 witness_weight = sum(witness_len) 906 907 overall_weight = funding_transaction_weight + witness_weight 908 909 910 ## Expected Weight of the Commitment Transaction 911 912 The *expected weight* of a commitment transaction is calculated as follows: 913 914 p2wsh: 34 bytes 915 - OP_0: 1 byte 916 - OP_DATA: 1 byte (witness_script_SHA256 length) 917 - witness_script_SHA256: 32 bytes 918 919 p2wpkh: 22 bytes 920 - OP_0: 1 byte 921 - OP_DATA: 1 byte (public_key_HASH160 length) 922 - public_key_HASH160: 20 bytes 923 924 multi_sig: 71 bytes 925 - OP_2: 1 byte 926 - OP_DATA: 1 byte (pub_key_alice length) 927 - pub_key_alice: 33 bytes 928 - OP_DATA: 1 byte (pub_key_bob length) 929 - pub_key_bob: 33 bytes 930 - OP_2: 1 byte 931 - OP_CHECKMULTISIG: 1 byte 932 933 witness: 222 bytes 934 - number_of_witness_elements: 1 byte 935 - nil_length: 1 byte 936 - sig_alice_length: 1 byte 937 - sig_alice: 73 bytes 938 - sig_bob_length: 1 byte 939 - sig_bob: 73 bytes 940 - witness_script_length: 1 byte 941 - witness_script (multi_sig) 942 943 funding_input: 41 bytes 944 - previous_out_point: 36 bytes 945 - hash: 32 bytes 946 - index: 4 bytes 947 - var_int: 1 byte (script_sig length) 948 - script_sig: 0 bytes 949 - witness <---- "witness" is used instead of "script_sig" for 950 transaction validation; however, "witness" is stored 951 separately, and the cost for its size is smaller.
