0de8a0d3 wallet_rpc_server: new estimate_tx_size_and_weight RPC (moneromooo-monero)
|
|
Adding a new `amounts` field ot the output of `get_transfers` RPC
method. This field specifies individual payments made to a single
subaddress in a single transaction, e.g., made by this command:
transfer <addr1> <amount1> <addr1> <amount2>
|
|
Even if it fails, the ring composition is known to a potential
adversary, and so we should reuse the same ring next time
|
|
|
|
|
|
If more than one thread wants to make sure of the spend secret key,
then we decrypt on the first caller and reencrypt on the last caller,
otherwise we could use an invalid secret key.
|
|
If the hashes received would move the current blockchain past the
stop point, the short history would not be updated, since we do
not expect another loop, but the daemon might return earlier hashes,
causing the end index to not be enough to reach the threshold and
this require another loop, which will download the same hashes and
cause an infinite loop.

Target height would be appropriate for the daemon, which syncs
off other daemons, but the wallet syncs off the daemon it's
connected to, and its target is the daemon's current height.
|
|
We get new pool txes before processing any tx, pool or not.
This ensures that if we're asked for a password, this does not
cause a measurable delay in the txpool query after the last
block query.
|
|
The "everything refreshed" state was detected when a refresh call did
not return any new blocks. This can be detected without that extra
"empty" call by comparing the claimed node height to the height of
the last block retrieved. Doing this avoids that last call, saves
some bandwidth, and makes the common refresh case use only one call
rather than two.
As a side effect, it prevents an information leak reported by
Tramèr et al: if the wallet retrieves a set of blocks which includes
an output sent to the refreshing wallet, the wallet will prompt the
user for the password to decode the amount and calculate the key
image for the new output, and this will delay subsequent calls to
getblocks.bin, allowing a passive adversary to note the delay and
deduce when the wallet receives at least one output.
This can still happen if the wallet downloads more than 1000 blocks,
since this will be split in several calls, but then the most the
adversary can tell is which 1000 block section the user received
some monero (the adversary can estimate the heights of the blocks
by calculating how many "large" transfers are done, which will be
sections of blocks, the last of which will usually be below 1000,
but the size of the data should allow the actual number of blocks
sent to be determined fairly accurately).
This timing trick still be used via the subsequent scan for incoming
txes in the txpool, which will be fixed later.
|
|
This lets a passive attacker with access to the network link
between node and wallet perform traffic analysis to deduce
when an idle wallet receives a transaction.

Lists nodes exposing their RPC port for public use
|
|
Daemons intended for public use can be set up to require payment
in the form of hashes in exchange for RPC service. This enables
public daemons to receive payment for their work over a large
number of calls. This system behaves similarly to a pool, so
payment takes the form of valid blocks every so often, yielding
a large one off payment, rather than constant micropayments.
This system can also be used by third parties as a "paywall"
layer, where users of a service can pay for use by mining Monero
to the service provider's address. An example of this for web
site access is Primo, a Monero mining based website "paywall":
https://github.com/selene-kovri/primo
This has some advantages:
- incentive to run a node providing RPC services, thereby promoting the availability of third party nodes for those who can't run their own
- incentive to run your own node instead of using a third party's, thereby promoting decentralization
- decentralized: payment is done between a client and server, with no third party needed
- private: since the system is "pay as you go", you don't need to identify yourself to claim a long lived balance
- no payment occurs on the blockchain, so there is no extra transactional load
- one may mine with a beefy server, and use those credits from a phone, by reusing the client ID (at the cost of some privacy)
- no barrier to entry: anyone may run a RPC node, and your expected revenue depends on how much work you do
- Sybil resistant: if you run 1000 idle RPC nodes, you don't magically get more revenue
- no large credit balance maintained on servers, so they have no incentive to exit scam
- you can use any/many node(s), since there's little cost in switching servers
- market based prices: competition between servers to lower costs
- incentive for a distributed third party node system: if some public nodes are overused/slow, traffic can move to others
- increases network security
- helps counteract mining pools' share of the network hash rate
- zero incentive for a payer to "double spend" since a reorg does not give any money back to the miner
And some disadvantages:
- low power clients will have difficulty mining (but one can optionally mine in advance and/or with a faster machine)
- payment is "random", so a server might go a long time without a block before getting one
- a public node's overall expected payment may be small
Public nodes are expected to compete to find a suitable level for
cost of service.
The daemon can be set up this way to require payment for RPC services:
monerod --rpc-payment-address 4xxxxxx \
--rpc-payment-credits 250 --rpc-payment-difficulty 1000
These values are an example only.
The --rpc-payment-difficulty switch selects how hard each "share" should
be, similar to a mining pool. The higher the difficulty, the fewer
shares a client will find.
The --rpc-payment-credits switch selects how many credits are awarded
for each share a client finds.
Considering both options, clients will be awarded credits/difficulty
credits for every hash they calculate. For example, in the command line
above, 0.25 credits per hash. A client mining at 100 H/s will therefore
get an average of 25 credits per second.
For reference, in the current implementation, a credit is enough to
sync 20 blocks, so a 100 H/s client that's just starting to use Monero
and uses this daemon will be able to sync 500 blocks per second.
The wallet can be set to automatically mine if connected to a daemon
which requires payment for RPC usage. It will try to keep a balance
of 50000 credits, stopping mining when it's at this level, and starting
again as credits are spent. With the example above, a new client will
mine this much credits in about half an hour, and this target is enough
to sync 500000 blocks (currently about a third of the monero blockchain).
There are three new settings in the wallet:
- credits-target: this is the amount of credits a wallet will try to
reach before stopping mining. The default of 0 means 50000 credits.
- auto-mine-for-rpc-payment-threshold: this controls the minimum
credit rate which the wallet considers worth mining for. If the
daemon credits less than this ratio, the wallet will consider mining
to be not worth it. In the example above, the rate is 0.25
- persistent-rpc-client-id: if set, this allows the wallet to reuse
a client id across runs. This means a public node can tell a wallet
that's connecting is the same as one that connected previously, but
allows a wallet to keep their credit balance from one run to the
other. Since the wallet only mines to keep a small credit balance,
this is not normally worth doing. However, someone may want to mine
on a fast server, and use that credit balance on a low power device
such as a phone. If left unset, a new client ID is generated at
each wallet start, for privacy reasons.
To mine and use a credit balance on two different devices, you can
use the --rpc-client-secret-key switch. A wallet's client secret key
can be found using the new rpc_payments command in the wallet.
Note: anyone knowing your RPC client secret key is able to use your
credit balance.
The wallet has a few new commands too:
- start_mining_for_rpc: start mining to acquire more credits,
regardless of the auto mining settings
- stop_mining_for_rpc: stop mining to acquire more credits
- rpc_payments: display information about current credits with
the currently selected daemon
The node has an extra command:
- rpc_payments: display information about clients and their
balances
The node will forget about any balance for clients which have
been inactive for 6 months. Balances carry over on node restart.

If the peer (whether pruned or not itself) supports sending pruned blocks
to syncing nodes, the pruned version will be sent along with the hash
of the pruned data and the block weight. The original tx hashes can be
reconstructed from the pruned txes and theur prunable data hash. Those
hashes and the block weights are hashes and checked against the set of
precompiled hashes, ensuring the data we received is the original data.
It is currently not possible to use this system when not using the set
of precompiled hashes, since block weights can not otherwise be checked
for validity.
This is off by default for now, and is enabled by --sync-pruned-blocks

One considers the blockchain, while the other considers the
blockchain and some recent actions, such as a recently created
transaction which spend some outputs, but isn't yet mined.
Typically, the "balance" command wants the latter, to reflect
the recent action, but things like proving ownership wants
the former.
This fixes a crash in get_reserve_proof, where a preliminary
check and the main code used two concepts of "balance".

According to [1], std::random_shuffle is deprecated in C++14 and removed
in C++17. Since std::shuffle is available since C++11 as a replacement
and monero already requires C++11, this is a good replacement.
A cryptographically secure random number generator is used in all cases
to prevent people from perhaps copying an insecure std::shuffle call
over to a place where a secure one would be warranted. A form of
defense-in-depth.

If `--daemon-ssl enabled` is set in the wallet, then a user certificate,
fingerprint, or onion/i2p address must be provided.
|
|
|
|
An override for the wallet to daemon connection is provided, but not for
other SSL contexts. The intent is to prevent users from supplying a
system CA as the "user" whitelisted certificate, which is less secure
since the key is controlled by a third party.
|
|
|
|
Currently if a user specifies a ca file or fingerprint to verify peer,
the default behavior is SSL autodetect which allows for mitm downgrade
attacks. It should be investigated whether a manual override should be
allowed - the configuration is likely always invalid.
|
|
Specifying SSL certificates for peer verification does an exact match,
making it a not-so-obvious alias for the fingerprints option. This
changes the checks to OpenSSL which loads concatenated certificate(s)
from a single file and does a certificate-authority (chain of trust)
check instead. There is no drop in security - a compromised exact match
fingerprint has the same worse case failure. There is increased security
in allowing separate long-term CA key and short-term SSL server keys.
This also removes loading of the system-default CA files if a custom
CA file or certificate fingerprint is specified.
