ERC721-based Software Licensing Framework

dotta-license's Issues

Update Dotlicense to use the latest EIP-721

See here: ethereum/EIPs#841

is the cli library published in npm? How do I install the cli tool?

Can dotta-license be used with ERC-20 tokens?

I would like to accept other ERC-20 tokens for payment instead of ETH. How would I be able to do that with dotta-license?

Discussion: Using Dotlicense for Subscription SaaS / Web Apps

I think Dotlicense could be used in a web context for SaaS apps. If you used a Metamask/signing-based login then you could use that proof of ownership to verify an active subscription.

For example, see meta-auth for a Metamask-based login with Node middleware. (Note: I haven't tried meta-auth and I can't vouch for it's security, but I think it's an interesting idea.)

This could work with Dotlicense like this:

1. The user has paid for a subscription-token on-chain
2. For a user to log in they sign a challenge, proving they own the given address (and the webserver sets a cookie so that this only has to be done as often as you would log in normally)
3. The webserver now knows the identity of the user, as well as the user's ETH address. This means the webserver can check on-chain if the user's subscription is valid and unlock features accordingly.

As of writing, I haven't built any of the supporting Web UI libraries nor the Node middleware, but once we have Dotlicense working, it should be straightforward to do this.

doc: how can I use with bulk licensing

If I want to give a bulk discount for say 10 licenses how would I do that. Additionally, how can I restrict a license to a particular "node". Is there a way to pass a machine uuid during the validate process and verify license validity? Are machine uuids stored in the contract?

Features: setInventory, setExpiration

Two features I'd like to add in a v2:

• setInventory - set the inventory of a product to a specific level, subject to supply constraints
• setExpiration - manually set the expiration of any subscription token - currently even admins can only renew in cycle-chunks.

is this project still maintained?

I've tried getting it running with Node 14 and 16 and not had any luck. I was able to compile the contracts at least, thanks to help from this web3/web3.js#3079 but I was unable to get any further than that. The CLI gives me a lot of node-gyp errors and doesn't seem to install properly.

Investigate EIP 1337 for subscriptions

EIP 1337 is standard for recurring payments / subscriptions and it is probably a good idea for the next version of dotta-license.

See:

• ethereum/EIPs#1337 and
• https://github.com/austintgriffith/tokensubscription.com/tree/13ced407c2709e99fbe7838a84a9d53f855b40bc

Use `external` instead of `public` where we can

dot-abi-cli example: tokensOfOwnerByIndex Couldn't decode uint256 from ABI: 0x

Ive poked at most of the function calls (that dont require gas) and they seem valid, but this one errors on me:

bash-3.2$ node cryptokitties-cli.js tokensOfOwnerByIndex 0xa6c366D97cb64708211f24310dFAd5363BC96a04 0

[Suggestion] Trial period?

Maybe it's there and I just don't see it but would be cool to be able to issue trial periods to users
