# Protocol Changes
|
|
|
|
The protocol has no central authority nor organization nor actors (such as
|
|
liquidity providers/validators) who can compel new protocol rules. The Serai
|
|
protocol is as-written with all granted functionality and declared rules
|
|
present.
|
|
|
|
Validators are explicitly granted the ability to signal for two things to occur:
|
|
|
|
### 1) Halt another validator set.
|
|
|
|
This will presumably occur if another validator set turns malicious and is the
|
|
expected incident response in order to apply an economic penalty of ideally
|
|
greater value than damage wrecked. Halting a validator set prevents further
|
|
publication of `Batch`s, preventing improper actions on the Serai blockchain,
|
|
and preventing validators from unstaking (as unstaking only occurs once future
|
|
validator sets have accepted responsibility, and accepting responsibility
|
|
requires `Batch` publication). This effectively burns the malicious validators'
|
|
stake.
|
|
|
|
### 2) Retire the protocol.
|
|
|
|
A supermajority of validators may favor a signal (an opaque 32-byte ID). A
|
|
common signal gaining sufficient favor will cause the protocol to stop producing
|
|
blocks in two weeks.
|
|
|
|
Nodes will presumably, as individual entities, hard fork to new consensus rules.
|
|
These rules presumably will remove the rule to stop producing blocks in two
|
|
weeks, they may declare new validators, and they may declare new functionality
|
|
entirely.
|
|
|
|
While nodes individually hard fork, across every hard fork the state of the
|
|
various `sriXYZ` coins (such as `sriBTC`, `sriETH`, `sriDAI`, and `sriXMR`)
|
|
remains intact (unless the new rules modify such state). These coins can still
|
|
be burned with instructions (unless the new rules prevent that) and if a
|
|
validator set doesn't send `XYZ` as expected, they can be halted (effectively
|
|
burning their `SRI` stake). Accordingly, every node decides if and how to future
|
|
participate, with the abilities and powers they declare themselves to have.
