I think I'll drop bf63317 and revert to only db63d5b (unless someone sees a blocking reason and the need to use uint32 instead of int32). Changing to uint32 needs many changes in FeeFrac (which I would like to avoid touching). In FeeFrac size is defined as an int32_t so using uint32 doesn't give us any "advantage". Friendly ping @davidgumberg @Eunovo @sipa to know your opinion :) |

- Passing negative virtual bytes to
GetFeewill return -1 as the fee.
From experimenting a bit, it seems to me that before this PR, a negative vsize would wrap from max value, i.e. GetFee(<negative>) would return huge amounts (here with a feerate of 1000 s/kvB):
./test/amount_tests.cpp(40): error: in "amount_tests/GetFeeTest": check feeRate.GetFee(-1) == CAmount(-1) has failed [4294967295 != -1]
./test/amount_tests.cpp(41): error: in "amount_tests/GetFeeTest": check feeRate.GetFee(-5) == CAmount(-1) has failed [4294967291 != -1]
The new behavior of throwing an assertion error on negative vsizes seems like an improvement to me.
./policy/feerate.cpp:22 GetFee: Assertion `virtual_bytes >= 0' failed.
unknown location(0): fatal error: in "amount_tests/GetFeeTest": signal: SIGABRT (application abort requested)

I was curious whether this test would have passed prior to this change, because the vsize was then expected to be an unsigned integer, and it does.

losely related nit: seems like CFeeRate serialization hasn't been used for more than a decade [1] (other than in the fuzz test) and we could as well just remove it; was shortly looking into that as I was worried that this line could change some file format
[1] AFAICT, the last use was removed in #5159

It lowers the default `-minrelaytxfee` and `-incrementalrelayfee`, and knocks `-blockmintxfee` down to the minimum nonzero setting. Also adds some tests for the settings and pulls in #32750. The minimum relay feerate is a DoS protection rule, representing a price on the network bandwidth used to relay transactions that have no PoW. While relay nodes don't all collect fees, the assumption is that if nodes on the network use their resources to relay this transaction, it will reach a miner and the attacker's money will be spent once it is mined. The incremental relay feerate is similar: it's used to price the relay of replacement transactions (the additional fees need to cover the new transactions at this feerate) and evicted transactions (following a trim, the new mempool minimum feerate is the package feerate of what was removed + incremental). Also note that many nodes on the network have elected to relay/mine lower feerate transactions. Miners (some say up to 85%) are choosing to mine these low feerate transactions instead of leaving block space unfilled, but these blocks have extremely poor compact block reconstruction rates with nodes that rejected or didn't hear about those transactions earlier. - #33106 (comment) - https://x.com/caesrcd/status/1947022514267230302 - https://mempool.space/block/00000000000000000001305770e0aa279dcd8ba8be18c3d5cf736a26f77e06fd - https://mempool.space/block/00000000000000000001b491649ec030aa8e003e1f4f9d3b24bb99ba16f91e97 - https://x.com/mononautical/status/1949452586391855121 While it wouldn't make sense to loosen DoS restrictions recklessly in response to these events, I think the current price is higher than necessary, and this motivates us changing the default soon. Since the minimum relay feerate defines an amount as too small based on what it costs the attacker, it makes sense to consider BTC's conversion rate to what resources you can buy in the "real world." Going off of [this comment](#32959 (comment)) and [this comment](#33106 (comment)) - Let's say an attacker wants to use/exhaust the network's bandwidth, and has the choice between renting resources from a commercial provider and getting the network to "spam" itself it by sending unconfirmed transactions. We'd like the latter to be more expensive than the former. - The bandwidth for relaying a transaction across the network is roughly its serialized size (plus relay overhead) x number of nodes. A 1000vB transaction is 1000-4000B serialized. With 100k nodes, that's 0.1-0.4GB - If the going rate for ec2 bandwidth is 10c/GB, that's like 1-4c per kvB of transaction data - Then a 1000vB transaction should pay at least 4c - $0.04 USD is 40 satoshis at 100k USD/BTC - Baking in some margin for changes in USD/BTC conversion rate, number of nodes (and thus bandwidth), and commercial service costs, I think 50-100 satoshis is on the conservative end but in the right ballpark - At least 97% of the recent sub-1sat/vB transactions would be accepted with a new threshold of 0.1sat/vB: #33106 (comment) List of feerates that are changed and why: - min relay feerate: significant conversion rate changes, see above - incremental relay feerate: should follow min relay feerate, see above - block minimum feerate: shouldn’t be above min relay feerate, otherwise the node accepts transactions it will never mine. I've knocked it down to the bare minimum of 1sat/kvB. Now that we no longer have coin age priority (removed in v0.15), I think we can leave it to the `CheckFeeRate` policy rule to enforce a minimum entry price, and the block assembly code should just fill up the block with whatever it finds in mempool. List of feerates that are not changed and why: - dust feerate: this feerate cannot be changed as flexibly as the minrelay feerate. A much longer record of low feerate transactions being mined is needed to motivate a decrease there. - maxfeerate (RPC, wallet): I think the conversion rate is relevant as well, but out of scope for this PR - minimum feerate returned by fee estimator: should be done later. In the past, we've excluded new policy defaults from fee estimation until we feel confident they represent miner policy (e.g. #9519). Also, the fee estimator itself doesn't have support for sub-1sat/vB yet. - all wallet feerates (mintxfee, fallbackfee, discardfee, consolidatefeerate, WALLET_INCREMENTAL_RELAY_FEE, etc.): should be done later. Our standard procedure is to do wallet changes at least 1 release after policy changes.

Based on current network conditions (in which nodes rejecting 0.1-1sat/vB are missing many transactions), it is recommended to change these policy settings. I did not include #32750 because it causes #33177 and I don't foresee any problems; it was just a nice to have. For reviewers: the backport is unclean but fairly straightforward. I just had to adapt a test that is no longer in master (#32973) and include `-datacarriersize` in order to pad transaction size (#32406).

nit: any reason to exclude negative values? They are documented to behave as-if 0 was passed, so it seems fine to keep the fuzz coverage for it? (https://maflcko.github.io/b-c-cov/fuzz.coverage/src/policy/feerate.cpp.gcov.html)
(There is a unit test covering it, so just a nit)

Negatives values would make the code crash because of the Assume introduced in GetFee

The
FeeFractype represents a fraction, intended to be used forsats/vbyteorsats/WU. It was added to improve accuracy when evaluating fee rates in cluster mempool. [1]But it can also be used to fix the precision issues that the current
CFeeRateclass has now.At the moment,
CFeeRatehandles the fee rate as satoshis per kilovirtualbyte:CAmount / kvBusing an integer.This PR fix
CFeeRateprecision issues by encapsulatingFeeFracinternally keeping backwards compatibility.This PR can also be used as a based to use multiple units on RPC calls as detailed in this issue [2].
