Summary

Security improvements were introduced into the network building the strength of the network. THORNames testing is underway in Stagenet before it will be released to Chaosnet. Mainnet planning is underway with THORNames and the Killswitch to be the last features activated in Chaosnet before a stability period starts. A lot of background work secure arrangements and complete technical documentation is underway.

THORFi resources were created and modeling has started to test THORFi economics in extreme cases. Kill Switch code was deployed into Chaoset with a start time yet to be set. Many network and community updates also occurred.

THORNames Testing in Stagenet

THORNames was released into Stagenet for testing with issues being found and fixed already. It can be tested using AsgardEx Desktop, more interface support is expected. Bounties are available for issues found in Stagenet. Once Testing is complete, it will be deployed to Chaosnet.

Example THORName in Stagenet is: https://stagenet-midgard.ninerealms.com/v2/thorname/lookup/ORION9RSTAGE

Kill Switch Update

The code for the Kill Switch was introduced into the network. Nodes will vote on a start time (start block) post Mainnet.

See more information on the Kill Switch and BEP2/ERC20 RUNE upgrade in the Upgrading to Native RUNE Article.

It is recommended you upgrade asap with the below guides:

How to switch to Native RUNE using Ledger (2 ways) — THORNoob
How to Switch Binance $RUNE to Native $RUNE (2 Ways: Arbitrage, Upgrade) — THORSwap
How to: Upgrade to Native RUNE (THOR.RUNE) Using ThorSwap DEX — LP University.

Native RUNE will be supported by major centralised exchanges allowing another path to upgrade non-native RUNE.

THORFi Update

Several good THORFi resources have been created to help the community better understand THORFi.

Introduction to THORFinance (THORFi) — LP University Article
THORFi — The Complete Guide — Grass Roots Crypto Video. Graphics and Spreadsheet Link.
THORFi Lending and Saving Numbers — Chad Barraford Video. Spreadsheet Link

THORFi Modeling

A tool called cadCAD is being used to simulate THORFi economics. The goal with the simulator is to allow the community to test various scenarios and understand how the system responds. As a community, we can identify situations that are undesirable for the protocol and add logic to protect/prevent that situation. Repo Link.

If anyone has experience with systems modeling please reach out!

THOFi Derived Asset PR merged

Core released creates derived assets like THOR.USD and THOR.BTC (which can be feature flagged on via mimir node voting). See the PR here. THORFi will land in Stagenet within 2 months.

Bug Disclosure

Disclosure (now fully patched): changing a single trailing bit 0x04 > 0x05 in a Pay to Public Key (P2PK) type transaction address leading byte (in the memo) causes multiple double-spends as the system cannot observe its own outbounds so keeps trying. This whole class of non-observe-outbound bugs is now thwarted by auto-halt chain when Ygg has abnormally sized (not gas related) bond fines. Also specifically P2PK is now explicitly disallowed to an outbound (nobody uses it anyway). Full Disclosure details here.

Security Improvements Introduced

1. Signing halt — a chain can be paused for signing, but still observe and sync. This was introduced after issues were caused post a Binance Chain hard fork where nodes and the network were affected. https://gitlab.com/thorchain/thornode/-/merge_requests/2223

2. Pause chain and Ygg Funds when Unauthorised transactions — Introduced in response to bug disclosure. If the majority of nodes detect an unauthorised transaction on a chain, it is assumed the network is being attacked so that chain will be paused as well as Ygg Funds (thus all network-based Txs on that chain). https://gitlab.com/thorchain/thornode/-/merge_requests/2188

Cloud Provider Limits Proposal

In an effort to improve decentralization of nodes, a new PR has been opened that would limit the percentage of nodes to be hosted by a single provider (ie AWS). Currently, about 50% of the nodes are on AWS and we want to create pressure to reduce this to no more than 1/3rd. This ensures that a single cloud provider wouldn’t be able to attack the network and cause a network disruption. Node Operators will vote to implement a 33% Limit. https://gitlab.com/thorchain/thornode/-/merge_requests/2204

Milestone Update

Security and stability are now the primary focus for the team as Mainet approaches. The below features will be the last to be released into Chaosnet before Mainnet launches, all other features will pushed post-Mainnet to ensure stable operations.

In the background, a lot of work is being conducted which will lead to announcements and support greater network integration.

The below milestones are required before Mainnet.

Development of Development Docs and XChainjs Docs— In Progress
THORNames Activation in Chaosnet — Testing in Stagenet
Ethereum Router upgrade to v4 — Target Release v1.88.0
