Summary:

This proposal suggests the addition of a new option for the Helium wallet PAY command: an optional (likely length/size restricted) alphanumeric memo/note field included with a wallet-to-wallet HNT payment transaction.

messages are not required to be acknowledged or may be blocked/filtered entirely.

This functionality is essential to implement imo (to mitigate harassment/spam).

With support for memos in payment_v2 transactions coming in helium/blockchain-core#768, I propose we close this HIP and discussion and let the community built apps on top of memos.

[jamiew]

Looks good to me. I'll defer to the HIP author @cvolkernick as far as closing this particular HIP vs. accepting this implementation vs. keeping this HIP open to invite a competing implementation.

helium/blockchain-core#768 is different from the HIP, but that is exactly what is supposed to happen during product development. IMHO 768 seems to balance blockchain efficiency with the more abstract goal of attaching identiifiers to payments, and the actual text of the "host-to-host messaging" could be implemented off-chain. That would also allow for more flexible options for identity and encryption.

[cvolkernick]

Sounds reasonable to me, the blockchain core change seems to be fundamentally enabling the intent behind the HIP. It was never written with any particular implementation in mind, only to spur discussion.

[abhay]

Curious if we consider this closed now that memos have been implemented on chain and other apps can use memos to build more fully featured host to host messaging.

Will stand by my previous response from 4/8. Worst case another HIP can be drafted if things don't pan out as intended/desired. Thanks to the development team for the implementation.

Propose closing this @jamiew?

Marked Deployed. This is considered addressed by the addition of payment_memo_v2 in audit 63
