This is a tiny PR to increase the time a peer remains banned. A peer is banned when the reputation drops below a threshold. With every second, the peer reputation is exponentially decayed towards zero. For the previous setup: - decaying to zero from (i32::MAX or i32::MIN) would take 948 seconds (15mins 48seconds) - from i32::MIN to escaping the banned threshold would take 10 seconds This means we are decaying reputation a bit too aggressive and misbehaving peers can misbehave again in 10 seconds. Another side effect of this is that we have encountered multiple warnings caused by a few misbehaving peers. In the new setup: - decaying to zero from (i32::MAX or i32::MIN) would take 3544 seconds (59 minutes) - from i32::MIN to escaping the banned threshold would take ~69 seconds This is a followup of: - https://github.com/paritytech/polkadot-sdk/pull/4000. ### Testing Done - Created a misbehaving client with [subp2p-explorer](https://github.com/lexnv/subp2p-explorer), the client is banned for approx 69seconds until it is allowed to connect again. cc @paritytech/networking --------- Signed-off-by: Alexandru Vasile <alexandru.vasile@parity.io>
NOTE: We have recently made significant changes to our repository structure. In order to streamline our development process and foster better contributions, we have merged three separate repositories Cumulus, Substrate and Polkadot into this repository. Read more about the changes here.
Polkadot SDK
The Polkadot SDK repository provides all the resources needed to start building on the Polkadot network, a multi-chain blockchain platform that enables different blockchains to interoperate and share information in a secure and scalable way. The Polkadot SDK comprises three main pieces of software:
Polkadot
Implementation of a node for the https://polkadot.network in Rust, using the Substrate framework. This directory
currently contains runtimes for the Westend and Rococo test networks. Polkadot, Kusama and their system chain runtimes
are located in the runtimes repository maintained by
the Polkadot Technical Fellowship.
Substrate
Substrate is the primary blockchain SDK used by developers to create the parachains that make up the Polkadot network. Additionally, it allows for the development of self-sovereign blockchains that operate completely independently of Polkadot.
Cumulus
Cumulus is a set of tools for writing Substrate-based Polkadot parachains.
Releases
Note
Our release process is still Work-In-Progress and may not yet reflect the aspired outline here.
The Polkadot-SDK has two release channels: stable and nightly. Production software is advised to only use stable.
nightly is meant for tinkerers to try out the latest features. The detailed release process is described in
RELEASE.md.
Stable
stable releases have a support duration of three months. In this period, the release will not have any breaking
changes. It will receive bug fixes, security fixes, performance fixes and new non-breaking features on a two week
cadence.
Nightly
nightly releases are released every night from the master branch, potentially with breaking changes. They have
pre-release version numbers in the format major.0.0-nightlyYYMMDD.
