Elements Project blockchain platform ==================================== [![Build Status](https://travis-ci.org/ElementsProject/elements.svg?branch=master)](https://travis-ci.org/ElementsProject/elements) https://elementsproject.org 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. * [Announcement of Confidential Assets](https://blockstream.com/2017/04/03/blockstream-releases-elements-confidential-assets.html) * [Confidential Assets Whitepaper](https://blockstream.com/bitcoin17-final41.pdf) to be presented [April 7th at Financial Cryptography 2017](http://fc17.ifca.ai/bitcoin/schedule.html) in Malta * [Confidential Assets Tutorial](contrib/assets_tutorial/assets_tutorial.py) * [Confidential Assets Demo](https://github.com/ElementsProject/confidential-assets-demo) * [Elements Code Tutorial](https://elementsproject.org/elements-code-tutorial/overview) covering blockchain configuration and how to use the main features. Features of the Elements blockchain platform ---------------- Compared to Bitcoin itself, it adds the following features: * [Confidential Assets][asset-issuance] * [Confidential Transactions][confidential-transactions] * [Federated Two-Way Peg][federated-peg] * [Signed Blocks][signed-blocks] * [Additional opcodes][opcodes] Previous elements that have been integrated into Bitcoin: * Segregated Witness * Relative Lock Time Elements deferred for additional research and standardization: * [Schnorr Signatures][schnorr-signatures] Additional RPC commands and parameters: * [RPC Docs](https://elementsproject.org/en/doc/) The CI (Continuous Integration) systems make sure that every pull request is built for Windows, Linux, and macOS, and that unit/sanity tests are run automatically.
