This updates the coinbase transactions to reward service nodes
periodically rather than every block. If you recieve a service node
reward this reward will be delayed x blocks, if you receive another
reward to the same wallet before those blocks have been completed it
will be added to your total and all will be paid out after those x
blocks has passed.
For example if our batching interval is 2 blocks:
Block 1 - Address A receives reward of 10 oxen - added to batch
Block 2 - Address A receives reward of 10 oxen - added to batch
Block 3 - Address A is paid out 20 oxen.
Batching accumulates a small reward for all nodes every block
The batching of service node rewards allows us to drip feed rewards
to service nodes. Rather than accruing each service node 16.5 oxen every
time they are pulse block leader we now reward every node the 16.5 /
num_service_nodes every block and pay each wallet the full amount that
has been accrued after a period of time (Likely 3.5 days).
To spread each payment evenly we now pay the rewards based on the
address of the recipient. This modulus of their address determines which
block the address should be paid and by setting the interval to our
service_node_batching interval we can guarantee they will be paid out
regularly and evenly distribute the payments for all wallets over this
- We also remove the distinction between service_node_total and
service_node_paid. Previously the portions payout may still have some
remainder dust loki that was not distributed, and or distributed to the
miner as the difference between the pay out and the base reward was
added to the miner.
This is still the case for backwards compatibility before HF16. After
HF16, dust is not allowed and everything is split with the remainder
dust going to the 1st contributor in the Service Node (the operator).
Changes naming scheme
- Block Producer: The Service Node/Miner reponsible for generating the block
- Block Leader: The Service Node that is at the top of the Service Node
List queue. They are also by default on pulse round 0, the block producer.
If that round fails, then the block producer is changed as per the LIP-6
with multi-block seeding.
This commit also re-writes validate miner TX to repeat some of the
verification code. This appears to be clearer than having multiple
variables that change the verification loop in small ways which was more
error prone than I'd like to tolerate.
With Service Node List now generating 2 coinbase rewards, block_winner
is ambiguous, so, distinguish the reward generated for nodes at the top
of the queued list as- queued_winner.
Merging payout entries can be done when batching is implemented instead
of drilling down too deep in implementation too early before the other
parts of Pulse are fleshed out.
Currently all the variables in here need to be added into every
compilation unit; C++17 inline constexpr avoids that by throwing away
the duplicates at link time, plus lets the compiler optimize things
away.
Also eliminates a side effect in `get_config()` that mutated the
variable (so that one `get_config()` would end up changing the data of a
previous `get_config()`). Instead `get_config()` is now always constant
and doesn't care about the hard fork version; instead there is a
convenience method to get the governance wallet_address which takes the
hf version.
Monero decided to implement this by rebuilding the blockchain class in
tests with another FakeDB. You can trivially avoid this by restructuring
get_block_longhash to not have a high level dependency on the blockchain
itself.
This changes the formula for HF15 to 66% service nodes, 24% miner, 10%
foundation, and changes the block reward from the current 28 and a bit
to a fixed 25 LOKI per block. SN reward and LF reward both increase,
miner reward gets cut substantially. This change is reflecting that
with checkpoints and blink the security provided by miners is
substantially reduced.
In HF16 (with pulse) we plan to become mining-free, with final rewards
also included here for that fork of 21 LOKI per block with 90% to SNs
and 10% to foundation. (This is tentative assuming pulse is implemented
in HF16).
- Fix assert to use version_t::_count in service_node_list.cpp
- Incoporate staking changes from LNS which revamp construct tx to
derive more of the parameters from hf_version and type. This removes
extraneous parameters that can be derived elsewhere.
Also delegate setting loki_construct_tx_params into wallet2 atleast,
so that callers into the wallet logic, like rpc server, simplewallet
don't need bend backwards to get the HF version whereas the wallet has
dedicated functions for determining the HF.
This allows anything to add burn amounts by specifying burn_fixed in the
loki_tx_params.
burn_percent is more complicated (because it is a percentage of the base
tx fee, not a percentage of the actual tx fee), and gets handled and
converted to a fixed amount in the wallet code.
This revamps the `loki_construct_tx_params` a bit to be able to carry
fixed and %-based burn amounts (in addition to the staking tx flag) and
modifies it to set the hf version from within wallet2 rather than at
construction.
This is then used to implement proper fee burning in the wallet
(replacing the uncommitted hack I was using up until now to test it) by
changing wallet2 to understand the burn amount: initially it adds a
placeholder amount so that an appropriate amount of space in tx extra is
taken up, then once the transaction has been built and final fees
calculated it replaces the placeholder with the final burn amount before
tx finalization.
Neither of these have a place in modern C++11; boost::value_initialized
is entirely superseded by `Type var{};` which does value initialization
(or default construction if a default constructor is defined). More
problematically, each `boost::value_initialized<T>` requires
instantiation of another wrapping templated type which is a pointless
price to pay the compiler in C++11 or newer.
Also removed is the AUTO_VAL_INIT macro (which is just a simple macro
around constructing a boost::value_initialized<T>).
BOOST_FOREACH is a similarly massive pile of code to implement
C++11-style for-each loops. (And bizarrely it *doesn't* appear to fall
back to C++ for-each loops even when under a C++11 compiler!)
