dmap

• dmap is a universal namespace defined by part of the Ethereum chain state.
• dmap <dpath> gets the 32-byte value at the given path.
• dpath is the path format and mini-language used by dmap.
• dpath is future-proof and extensible.

Try it now:

npm install -g dmap-cmd

dmap .x.ample.        # Query
dmap walk .x.ample.   # Details

Quickstart on .x.: dmap .x.your-name.

If you want a valuable name, you should make a valuable namespace.

Examples

> dmap .x.
0x180513ff7459ebc79534d3cb8ac26a5a1ac8af0d

> dmap .x.ample.

> dmap walk .x.ample.
walk .x.ample.
step .x.ample.
step read .x.ample.
step read -r 0x20d20820f5d4D310281533CD9154C1bE22D6e195 .x.ample.

Use Cases

Our goal is to make dmap usable for the following initial use cases as quickly as possible.

• Package integrity check
• GUI integrity check
• Key signing / WoT bootstrapping

Any time you sign an update to a "named something", you could be signing it with a multisig or any other smart contract.

Development Notes

• At its core, this project is about dpath semantics.
• Version 0.0.x has an unstable API. Version 0.1.0 will have a stable read and walk API for paths containing only . runes (separators).
• dmap command line commands define a query language. dmap libraries should implement dmap("walk .x.ample.path"). first and .walk().x.ample.path() helper methods second.
• We expect other implementations to be forks of Ethereum light clients optimized for dmap queries.

Agenda

• dmap type-info by path, by address
• . rune
• : rune
• source bootstrap (git hash on chain, dmap update verifies it before linking)
• ^ rune
