Sequentia project blockchain platform

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

https://www.sequentia.io/

Current code is based on Elements Version: 23.2.4

Quick build - Linux

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'

NOTE: For building Sequentia with clang use:

export CONFIG_SITE=$PWD/depends/x86_64-pc-linux-gnu/share/config.site NOWARN_CXXFLAGS='-Wno-deprecated -Wno-unused-result' CC=clang CXX=clang++

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)

Run the node

Currently Sequentia supports only testnet, but you can also run the node as a custom Elements chain and create your network.

• Testnet mode: elementsd -chain=test (syncs with Sequentia testnet)
• Custom chain: elementsd -chain=<your_chain_name>

Elements info

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.
