Summary:

Hotspot owners, HNT holders, and other Helium participants, have different ways to organize assets. This HIP proposes a multi-signature key which can be used to authorize a transaction on the Helium blockchain. This key is a composite of the scalar keys which can be combined to generate a minimal subset of signatures required to make a valid transaction.

There has been universally positive support for this HIP in GitHub commnents, Discord chats, the most recent community call and there were 100% "yes" votes from 49 people in a straw poll. In recognition of this I am pleased to recognize this HIP as approved by the Helium community and will update statuses accordingly.

@xandkar @Vagabond would it be possible to link to any existing PRs in other repositories? Someone mentioned work was already in-flight

[xandkar]

@jamiew here's what's been done so far:
Basic support: helium/libp2p-crypto#10
Payment test: helium/blockchain-core#777
Canonicalization of key order: helium/libp2p-crypto#13

Close as implemented @jamiew ?

Is there any info/documentation on how to use multisig?

[jamiew]

@abhay yes please! Did this require a chainvar deployment? Do you have a favorite link to use for Deployed and/or Audit links?

[jamiew]

Is there any info/documentation on how to use multisig?

It's currently only available for chainvar transactions, imagine more will be coming later

[abhay]

Propose closing this as deployed @jamiew?

[abhay]

Now deployed – Same details as #158

Actually not exactly. Chain vars use a different multisig model. This is for on chain accounts/keys.

[mfalkvidd]

If we can use multisig for accounts, some sort of documentation would be very useful.

From what I have read, HIP 29 has been merged, however support for it needs to be added to helium-wallet. Until that has happened, there will be no effective way for users to utilize multi-sig, is that correct?

[mfalkvidd]

@GrahamJenkins yes that is correct

[abhay]

Initial support has been implemented in helium/helium-crypto-rs#21 and additional support will need to be added to the CLI parts of https://github.com/helium/helium-wallet-rs to consider the rust wallet complete.
