* Introduce inherent digests * Implement inherent digests * fix silly error * Implementation of inherent digests in BABE All tests pass. There are still limitations: 1. The runtime strips out inherent digests, so BABE must re-add them. 2. The test runtime checks that it can re-compute all digests. It can’t, so I had to comment out that test. * Fix compilation and seal import Seals were not imported correctly: the pre-digest was imported twice, instead of both it and the seal being imported. Also, other parts of the code did not compile due to incomplete refactoring. * Remove bogus assertion * Fix testsuite compilation * Remove unused import * Fix compiler diagnostics * Add inherent digest parameters to block constructors This enforces that inherent digests are added first. * Fixup Cargo.lock * Fix build errors * Re-add an incorrectly removed import * Bump primitive-types version * Update Cargo.lock * Refactoring * Use inherent digests for AuRa They do reach the runtime, but get stripped. I have not figured out where. * Fix compilation errors * Fix compilation errors due to incorrect types * Fix whitespace Suggested-by: Tomasz Drwiega <tomasz@parity.io> * Add preamble Suggested-by: Tomasz Drwiega <tomasz@parity.io> * Fix silly compile error * Refactor pre-digest finding code into a separate function * Remove unwanted assertion It is too likely to bring down the entire blockchain. Suggested-by: Tomasz Drwiega <tomasz@parity.io> * Use `find_pre_digest` after runtime, too Also, use `Member` trait rather than rolling our own requirements. Suggested-by: Tomasz Drwiega <tomasz@parity.io> * Fix various warnings mostly due to upgrading the dependency on `error_chain`. * Pre-digests nearly complete This nearly completes the implementation of pre-runtime digests. * `Seal2` → `Seal` and fix test suite * Try to fix the storage error * Try to fix storage (again) * Fix tests * Hopefully finish pre-runtime digests The key is to pass *only* the pre-runtime digests to the runtime. The others must be stripped out by `initialize_block`. * Fix silly typo * Fix another silly mistake * Remove unnecessary filtering of BABE pre-digests We no longer get duplicate BABE pre-digests, so if they appear, the header should be rejected outright. * Update Cargo.lock files * Reformatting * Fix silly typo in inherent digest code Also, revert `error.rs` files that contained calls to the `error_chain!` macro. * Try to keep the runtime from stripping pre-digests Currently runs into the “Storage root must match that calculated” assertion. * Don’t compute storage root until storage changes are done. Also, fix a compilation error. * Fix compile-time error * Fix compilation errors * Fix more compile errors * Hopefully it compiles this time… * Fix compilation and add docs * Prevent BABE from adding duplicate pre-runtime digests Found by comparing with the AuRa code. I also did some refactoring. * Respond to review and fix some warnings * Delete some dead code introduced earlier * More dead code goes away * `ref mut` → `&mut` * Respond to review and fix some warnings * Fix compilation error * Remove unneeded `HashT` type parameter Suggested-by: Robert Habermeier <robert@parity.io> * Remove spurious #[allow(deprecated)] * Document inherent digest parameter to `build_block` * Delete `Simple` trait It wasn’t needed * delete wrongly added files * Fix trait bounds * Digest serialization tests I also did some reformatting and cleanup. * Apply suggestions from code review Reformatting Co-Authored-By: André Silva <andre.beat@gmail.com> * Swap two arguments to `propose` and `propose_with` Also, remove some needless unsafe code. * Remove bogus `#![allow(deprecated)]` annotations With the removal of the deprecated `Seal` variant, these are not needed. * Add a missing `#[allow(deprecated)]` in the AuRa tests * Fix silly compile error * Fix silly compiler error RLS did not tell me that I hadn’t fixed `babe/lib.rs`, so I missed it. * Fixes made automatically by Cargo
Template Node
A new SRML-based Substrate node, ready for hacking.
Building
Install Rust:
curl https://sh.rustup.rs -sSf | sh
Install required tools:
./scripts/init.sh
Build the WebAssembly binary:
./scripts/build.sh
Build all native code:
cargo build
Run
You can start a development chain with:
cargo run -- --dev
Detailed logs may be shown by running the node with the following environment variables set: RUST_LOG=debug RUST_BACKTRACE=1 cargo run -- --dev.
If you want to see the multi-node consensus algorithm in action locally, then you can create a local testnet with two validator nodes for Alice and Bob, who are the initial authorities of the genesis chain that have been endowed with testnet units. Give each node a name and expose them so they are listed on the Polkadot telemetry site. You'll need two terminal windows open.
We'll start Alice's substrate node first on default TCP port 30333 with her chain database stored locally at /tmp/alice. The bootnode ID of her node is QmRpheLN4JWdAnY7HGJfWFNbfkQCb6tFf4vvA6hgjMZKrR, which is generated from the --node-key value that we specify below:
cargo run -- \
--base-path /tmp/alice \
--chain=local \
--alice \
--node-key 0000000000000000000000000000000000000000000000000000000000000001 \
--telemetry-url ws://telemetry.polkadot.io:1024 \
--validator
In the second terminal, we'll start Bob's substrate node on a different TCP port of 30334, and with his chain database stored locally at /tmp/bob. We'll specify a value for the --bootnodes option that will connect his node to Alice's bootnode ID on TCP port 30333:
cargo run -- \
--base-path /tmp/bob \
--bootnodes /ip4/127.0.0.1/tcp/30333/p2p/QmRpheLN4JWdAnY7HGJfWFNbfkQCb6tFf4vvA6hgjMZKrR \
--chain=local \
--bob \
--port 30334 \
--telemetry-url ws://telemetry.polkadot.io:1024 \
--validator
Additional CLI usage options are available and may be shown by running cargo run -- --help.
