Reingests particles, templates and particle JSON schemas from the specified environments

Reference implementation of the ERC-721 non-fungible token standard.

An on-chain system for providing accurate and understandable user feedback by converting machine-efficient codes into human-readable strings in any language or phrasing

An extension to the ERC-20 standard token, which allows tokens to be put on hold. This guarantees a future transfer and makes the held tokens unavailable for transfer in the mean time. Holds are similar to escrows in that are firm and lead to final settle
