Sequentia Project blockchain platform

https://sequentia.io/

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

Current code is based on Elements Version: 23.2.1

Quick Ubuntu build instructions for development:

Instal build tools

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

Install clang 15:

wget -O - "https://apt.llvm.org/llvm.sh" | sudo bash -s 15

Setup ccache:

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

Build:

./autogen.sh
./contrib/install_db4.sh .
export CC=clang-15 CXX=clang++-15 BDB_LIBS="-L${BDB_PREFIX}/lib -ldb_cxx-4.8" BDB_CFLAGS="-I${BDB_PREFIX}/include"
./configure --without-gui --without-natpmp --without-miniupnpc
make -j$(nproc)

To speed up the build if not necessary, disable bench and tests in configure:

./configure --without-gui --without-natpmp --without-miniupnpc --disable-bench --disable-tests

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, it 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.
