Ignotus Peverell e4ebb7c7cb Cleanup HTTP APIs, update ports to avoid gap, rustfmt
Moved the HTTP APIs away from the REST endpoint abstraction and
to simpler Hyper handlers. Re-established all routes as v1.
Changed wallet receiver port to 13415 to avoid a gap in port
numbers.

Finally, rustfmt seems to have ignored specific files arguments,
running on everything.

Yeastplume 05d22cb632 changing secp import to tag, and consolidating Cargo.toml import (#220) 2017-10-31 23:20:55 +00:00
Ignotus Peverell f1488f9529 Lots of chain sync and block validation fixes
* Fix for the chain pipeline partly relying on an outdated head,
leading to not properly recognizing a fork and inconsistent sum
tree state.
* Do not drop block requests during sync that don't get satisfied,
retry enough time to get them and avoid stall.
* Always validate header, even in sync where we may have validated
it already. We don't want a block coming from a peer that could
squeeze through with an invalid header.
* When syncing, do not mark blocks that were errored by the chain
as received (typical case: orphan). Keep retrying.
* Improved chain state dump for debugging.
* Do not add to orphans blocks too far in the future.
* Better error reporting on db errors.
* Related sync test fixes.

TODO figure out why syncing peers timeout so often, very useful
to test but not that great for a fast sync experience.

AntiochP 9a230ca7f6 fail deserialization if inputs or outputs are not sorted for txs (#173)
* fail deserialization if input or outputs are not sorted for txs, fail deserialization if inputs or outputs or kernels are not sorted for blocks, make sure we sort them before serialization

AntiochP 86420d4bca Shorter identifiers and call them key_id (not pubkey) (#175)

Ignotus Peverell 7012d37f5f Half of fees get rewarded, half burnt. Minor cleanups
Update coinbase building and block summation to account for half of
the fees going to the coinbase. Forcing fees to be even as a
consequence. Now that we can't build the coinbase independently
from the block (because fees), had to update the miner to keep the
key derivation so a new derivation isn't made any time a new block
gets worked on.

Minor doc and warning cleanups.

AntiochP 95a92eefc9 Cannot spend coinbase for N blocks (#111)
* use head_header in add_to_memory_pool
* add COINBASE_MATURITY const to consensus
* add coinbase maturity (wip) validaton rule to validate_block
* add coinbase maturity check to validate_block
* map errors in adapters - specific errors still wip
* reworked so adapter translates chain errors to pool errors (core errors not required)
* add test for spending immature coinbase in memory pool
* wip - add test to cover spending coinbase output in chain.process_block
* added test coverage around process_block - we have a problem with coinbase output commitments
* add a comment on the failing test
* process_block will now fail validation if we attempt to spend coinbase that has not yet matured
(remember to use a new reward_key for every block). test coverage in place to verify this

Yeastplume 97b7421ce0 Mining test debug output, fixes to diff. adjustment and start of POW documentation (#69)
* Beginning to add a POW description, and some minor changes to mining testing, addition of further debug information to mining output.
* Many additions to create first draft of POW documentation
* Fixes to difficult adjustments by adding a MINIMUM_DIFFICULTY consensus value. Otherwise never adjusted above 1 due to flooring.

Ignotus Peverell e8a6b61100 Apply new difficulty algo, remove configurable cuckoo size
Integrate the new difficulty calculation into the block chain
validation, the miner and tests. As the difficulty calculation
doesn't use varying Cuckoo sizes anymore and we narrowed down
reasonable final Cuckoo Cycle parameters, removed all Cuckoo
Cycle sizes from block headers.

Formalized easier Cuckoo Cycle sizes for testing (and possibly
testnet) by introducing a test mode in configuration. Updated
all tests.

Ignotus Peverell eb9cc7ef13 Integrate transaction pool with rest of the system
* Transactions coming from the network are now pushed to the pool
through the net adapter.
* New blocks accepted by the chain are sent to the pool for
eviction.
* The miner requests transactions from the pool to build its
blocks.
* The push API adds to the pool, removing the mock.
* Implementation of the adapter to the chain required by the pool
to get consistent UTXOs. Grossly unoptimized until we have the UTXO
MMR ready.

Ignotus Peverell 791d2355ee Miner querying wallet receiver for coinbase output
With the coinbase receiver daemon in place, when starting a Grin
server in mining mode, the miner will now ask the receiver for a
coinbase output. The output is then used to insert in a block when
successfully mined.

Ignotus Peverell ac553493f1 WIP: Wallet functionality to receive and send coins
Beginning of a first pass at simple wallet functionalities so
Grin can be used to author transactions. We introduce a
receiving server, to be at least able to build coinbase outputs
that can be used by the mining daemon.

Present:

* Coinbase receiving API.
* Command to start the receiving server.
* Beginning of a transaction sending command.
* Improvements to the REST API abstractions to support the above.

Still to do:

* Change to the miner daemon to use the receiving server.
* A command line sender.
* API to receive any transaction (not just coinbase).
* A command line receiver.

Beyond that, HD derivation and seed generation are very simple
so far and almost certainly insecure. Just for testing for now.

Jacob Payne 8ffc0c6f8e Delegate Block Encoding to Store (#44)
Builds codecs to encode and decode blocks, block headers, transactions, kernels, etc. Will be used by the store and peer-to-peer layer for serialization, but also to compute hashes. Separates out serialization from core.

Ignotus Peverell 38d5d67e79 Add features bitmask to Block, Output, Kernel; coinbase validation
Block, Output and Kernel now have bitmasks to hold supported
features and eventually versioning. Will make adding features and
updates easier and open the possibility of soft forks.

First added feature for Output and Kernel is the marking of coinbase
related ones. Allows the validation of the coinbase part of a block.

Ignotus Peverell b6b815f6c1 Reintroduce block tests with new tx building
The build module introduced some facilities to build transactions
that can now be leveraged when building blocks and in related
tests.
2017-03-20 14:32:11 -07:00
Ignotus Peverell 6bd3fc0d48 Cleanup of Transaction and Block data structures
Some renaming and cleanup of the Input, Output, Transaction and
Block structs. The main change is the removal of all the overt
structures which are now replaced by a specialized module to
build transactions easily. More specifically:

* Rename the TxProof to TxKernel in Block to reflect the current
naming consensus in MimbleWimble.
* Change Input and Output to be plain structs instead of enums
making their manipulation a lot easier. The building of
transactions is now handled by the build module.
* Input now directly includes the commitment of the Output it's
spending instead of going through an intermediate hash.
* The new build module encapsulates all the transaction building
logic, making it very straightforward by chaining combinators.
* Moves some tests to the core mod.rs as they required being able
to build a transaction to test it.

Ignotus Peverell cb84f588fb Small tweaks and addition to a Transaction to make 2-parts building easier. Unit test covering the standard exchange between 2 parties when building a transaction. 2017-03-11 13:48:33 -08:00

Ignotus Peverell dda223f25b Chain logic to support multiple forks, select the most worked fork as the head. Significantly simplified from the original direction as it doesn't seem that explicitly materializing forks is necessary. Simple total difficulty accounting in block headers helping a lot there. 2017-01-09 15:16:44 -08:00
Ignotus Peverell 85e3255ee4 Removed need for a PowHeader. Directly checking serialization mode in block header serialization instead. 2017-01-09 12:07:38 -08:00
Ignotus Peverell ce23dda6cb Block headers maintain total difficulty up to previous. Changed all references of target to difficulty to stay consistent. Ported retargeting algo to use difficulty as well. 2016-12-26 15:39:31 -08:00
