Change PoW to Equihash #15
Conversation
Tested: make (macOS 10.12.5, Xcode 8.3.3)
Tested: make
Protocol version: 70016 (BTG_HARD_FORK_VERSION) Version bits: 0x60000000
- Add two new fields: nHeight, nSolution (for Equihash) - Calculate block hash in new block format after the hard fork. - Serialize block in legacy format when talking to Bitcoin node. Tested: unittest
|
Compact block is broken by new block format. Seems we have to fix it. |
Tested: ./autogen.sh && make
- Initialize sodium on startup - Add Equihash validation logic - Fix missing htole32 problem in mingw build.
|
Watching this one closely, interested to add this coin to the pool on launch.. |
|
(Zcash developer here.) Zcash will also need to add compact blocks. We haven't thought about it much yet but our ticket for that is https://github.com/zcash/zcash/issues/2316 . Let's cooperate on a spec. |
- Serialize in different formats based on the net protocol version. - Remove the version bit 0x40000000. - Support legacy block format for RPCs: getblock, getblockheader, getblocktemplate, submitblock. - Temporarily disable SEND_CMPT. Tested: unit tests
Intended broken testes: - p2p-compactblocks.py - rest.py Tested: reg tests.

- Add fields to block header for Zcash compatibility - Extend the nonce from `uint32_t` to `uint256` - Add 'nonceUint32' for backward compatibility: - RPC: 'getblockheader', 'getblock' - Rest: '/rest/headers', '/rest/block' Tested: ./src/test/test_bitcoin ./test/functional/test_runner.py (all passed except intended failures: p2p-compactblocks.py, rest.py)

Boa tarde, qual a previsão de Exchange terá o BTG? (BITCOINGOLD)? |
Also add a test to ensure Zcash compability. Tested: ./src/test/test_bitcoin --run_test=btg_tests
Tested: ./src/test/test_bitcoin --run_test=sanity_tests
Tested: ./src/test/test_bitcoin --run_test=equihash_tests
- RPC - generate - generatetoaddress - getblocktemplate - Add regtest `btg-hardfork.py` Tested: ./src/test/test_bitcoin ./test/functional/test_runner.py

It's time to do mining tests. No way to do it in a regular regression test as there's no existing Equihash solver in Python. |
|
https://github.com/str4d/zcash-pow Isn't this an Equihash python solver? |
|
@h4x3rotab Is the daemon ready for pool integration now? |
|
This change should be further tested but for now let's merge it to the staging tree. I will create another issue to track the process of PoW changes & tests. Will submit after it passes TravisCI check. |

This ongoing PR changes the PoW to Equihash. The implementation of Equihash is taken from Zcash project.
It will include the following modifications:
