Understanding Chip Resolution

Problem and Purpose

Given an arbitray chip discovered by a user, the chip's public key or chipId may be used to lookup information about the chip that:

1. Authenticates who manufactured the chip and embedded it into a project.
2. The current owner of the chip.
3. A primaryService with content that the chip should be redirected to upon scan (e.g a web app, URL or IPFS dapp)

Lookup Functions

The ChipRegistry provides the following functions that can be used to lookup an associated chip. Likewise, chip information is mapped in chipEnrollments, including such information as what project a chip is assocaited with.

• resolveChip - the primary service content assocaited with a chip, including the redirectUri; this is the entry point for most dapps into ERS.
• ownerOf - the current owner of the chip, set to the project owner at the time of addition.
• node - the ERS node of the chip.
