Sequentia Project blockchain platform

Sequentia is a Bitcoin sidechain dedicated to asset tokenization and decentralized exchanges.

https://sequentia.io/

Current code is based on Elements Version: 23.2.1

Installing Prerequisistes

Install build tools

On Ubuntu (and probably Debian), you should be able to install the prerequisite build tools with the following command:

sudo apt install ccache build-essential libtool autotools-dev automake pkg-config bsdmainutils python3

YMMV on other software distributions.

Setup ccache

You may achieve speedups when building and rebuilding by using ccache, that you may install and configure as follows:

sudo /usr/sbin/update-ccache-symlinks
echo 'export PATH="/usr/lib/ccache:$PATH"' | tee -a ~/.bashrc
source ~/.bashrc

Configure and Build

Prepare configuration

./autogen.sh
make -j$(nproc) -C depends NO_QT=1 NO_NATPMP=1 NO_UPNP=1 NO_ZMQ=1 NO_USDT=1
export CONFIG_SITE=$PWD/depends/x86_64-pc-linux-gnu/share/config.site NOWARN_CXXFLAGS='-Wno-deprecated -Wno-unused-result'

Configure

./configure --enable-any-asset-fees --enable-debug --disable-bench --disable-tests --disable-fuzz-binary

Note that the --enable-any-asset-fees flag is an addition by Sequentia, that will configure RPC documentation to denominate fee rates using RFU and rfa instead of BTC and sat.

Last But Not Least, Build

make -j$(nproc)

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
• Confidential Assets Whitepaper to be presented April 7th at Financial Cryptography 2017 in Malta
• Confidential Assets Tutorial
• Confidential Assets Demo
• Elements Code Tutorial covering blockchain configuration and how to use the main features.

Features of the Elements blockchain platform

Compared to Bitcoin itself, Elements adds the following features:

• Confidential Assets
• Confidential Transactions
• Federated Two-Way Peg
• Signed Blocks
• Additional opcodes

Previous elements that have been integrated into Bitcoin:

• Segregated Witness
• Relative Lock Time

Elements deferred for additional research and standardization:

• Schnorr Signatures

Additional RPC commands and parameters:

• RPC Docs

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.
