Ontology (ONT) Support

[TedNIVAN]

Hello there,

Based on the developer guide, here is the information needed to get Ontology (ONT) support for Trezor.

First of all, a quick overview about ONT:

Ontology is a new high-performance public blockchain project & a distributed trust collaboration platform. Ontology provides new high-performance public blockchains that include a series of complete distributed ledgers and smart contract systems.

More here:

• https://ont.io/

What is the approximate scale?

Similar scale than the already supported ones.

Do we need any new cryptographic primitives to support this coin?

ONT uses ECDSA, SM2, and ED25519.

You can check that out here:

• https://dev-docs.ont.io/#/docs-en/OntologyCli/04-wallet-management
• https://github.com/ontio/ontology-crypto

Is there (or will you develop) a frontend wallet that will support Trezor with this coin?

We currently have no frontend wallet that supports Trezor. However, this should be added to future development.

Provide links to relevant developer documentation, esp. about address format and transaction signing

Address format: https://dev-docs.ont.io/#/docs-en/OntologyCli/04-wallet-management

Transaction signing:

• https://github.com/ontio/ontology/tree/06b54d720c33a34d145d256872aeef577801b49c/core/signature

Provide a link to a transaction explorer

Let me now if you need further information,

Kind regards, Ted NIVAN
