[Do not merge] Feat/app chain mvp

10

This PR implements initial working support for appchains. I have a write-up here on how to test a live deployment on testnet here: https://gist.github.com/jcnelson/c982e52075337ba75e00b79942164e31 ## What's an Appchain? Appchains are...

chore: force runtime panics due to errors other than invalid blocks or microblocks

1

Update `append_block()` and its dependent methods so that errors in block processing due to reasons other than blocks or microblocks being invalid all trigger runtime panics. Leaving as a draft...

Chainstate: Chains coordinator is too aggressive at (re-)trying to handle burnchain blocks on boot-up

1

The chains coordinator will call `handle_burnchain_block()` once per sortition when the node boots up, which over time will cause the node to spend hours and hours of needless I/O time...

chains coordinator: re-validate anchor blocks against pox bitvector on boot-up?

1

If for some reason the Stacks node is stopped and restarted after being in a state where it had processed one or more reward cycles without anchor blocks, but for...

Right now, `StacksChainState::process_stacking_ops()` is hardcoded to use `.pox` as the contract name for calling `stack-stx` from an on-BTC stacking transaction. This contract name needs to switch over to `.pox-2` automatically...

Lots of these tests aren't really related to mining, but depend on test infrastructure in this file. They should be refactored, so that tests can live closer in the codebase...

[clairty] add functions to query the transaction asset map as it is running

4

The `(as-contract)` built-in should be extended to take a list of post-conditions on assets moved by the contract, in order to guard against things the contract might do (or might...

The `get-burn-block-info?` built-in should expose the recipient addresses for a given burn block height (e.g. as a `(list 2 principal)`).

[burnchain] the block-commit at the end of the reward cycle's pay-out period will never be valid if the size of the reward set is odd

2

The `LeaderBlockCommitOp::check_pox()` method contains a snippet of code that will ensure that a reward cycle with an odd number of reward slots is terminated with a burn address, thereby ensuring...

In-band upgrades: vote on exit-at-block-height

1

Create a designated smart contract that lets miners and STX-holders vote on a `exit-at-block-height` value that, when chosen, will cause the Stacks chain to cease processing blocks at that height...
