QuarkChain is building a blockchain with a focus on speed and scalability. They hope to significantly improve transaction times and reduce fees with an architecture that will rely on a two-layered blockchain and elastic sharding. QuarkChain uses a hybrid Proof-of-Work (PoW) consensus mechanism that is ASIC-resistant. Transactions are first confirmed on one blockchain layer, and then on the second. The network will be powered by the QKC coin.

Bytom is a Chinese company that is developing a blockchain platform that is specifically designed to register securities and physical assets to the Bytom blockchain. Bytom aims to create a secondary markets for these blockchain registered assets and will allow them to be tokenized.
Bytom is compatible with other platforms and enables high transaction speeds and anonymity.
One of Bytom's key features is its improved PoW consensus algorithm that is compatible with AI-enhanced ASIC chips. This allows for more efficient mining that uses less energy.

Stakenet is a blockchain with a unique Trustless Proof of Stake (TPoS) consensus mechanism that allows users to participate in the staking process without having to freeze their coins in the wallet. It's powered by the native coin XSN and is managed by its own masternodes. Stakenet (XSN) was created to build an ecosystem that allows easy and secure offline staking and cross chain communication. It has characteristics of Bitcoin, Dash and Peercoin, that were modified for their own purposes. XSN uses the Bitcoin Core, an improved Dash masternode architecture, and Peercoin's validation mechanism for creating new blocks.
