This is the integration and staging tree for the Elements blockchain platform,
a collection of feature experiments and extensions to the Bitcoin protocol.
This platform enables anyone to build their own businesses or networks
pegged to Bitcoin as a sidechain or run as a standalone blockchain with arbitrary asset tokens.

Modes
-----
Elements supports a few different pre-set chains for syncing. Note though some are intended for QA and debugging only:
* Liquid mode: `elementsd -chain=liquidv1` (syncs with Liquid network)
* Bitcoin mainnet mode: `elementsd -chain=main` (not intended to be run for commerce)
* Bitcoin testnet mode: `elementsd -chain=testnet3`
* Bitcoin regtest mode: `elementsd -chain=regtest`
* Elements custom chains: Any other `-chain=` argument. It has regtest-like default parameters that can be over-ridden by the user by a rich set of start-up options.

Confidential Assets
----------------
The latest feature in the Elements blockchain platform is Confidential Assets,
the ability to issue multiple assets on a blockchain where asset identifiers
and amounts are blinded yet auditable through the use of applied cryptography.
