Komodo A privacy-focused cryptocurrency protocol with decentralized exchange capabilities

Komodo is smart chain platform built with end-to-end blockchain development from a custom smart chain to an open API.

Background

Komodo is an open, composable multi-chain platform. A code fork of Zcash with blockchain development roots going back to 2014, Komodo is consistently recognized as a pioneer of multi-chain architecture in the blockchain space.

Komodo focuses on providing business-friendly blockchain solutions that are secure, scalable, interoperable, and adaptable. Komodo's current technology suite, the Antara framework, offers tools for end-to-end blockchain development, including a customizable, application-specific Smart Chain complete with a library of built-in modules and an open API for building blockchain-based applications.

Technology

Komodo employs a delayed proof-of-work (dPoW) consensus mechanism that it believes offers a higher level of network security than Bitcoin's PoW model. Every chain, even forks, are more connected under dPoW than regular PoW which Komodo prefers.

Komodo's Iguana Core technology, a multi-purpose code base that underlies the Komodo protocol, spawned the security model behind dPoW. Iguana Core and dPoW rely on Notary Nodes chosen by the Komodo network users to archive "true" copies of the network's transaction history and designate the appropriate chain for miners to direct their resources. Notary nodes occasionally receive easy-mining privileges on a lottery basis where the network's difficulty significantly decreases for one of the notary nodes. Every 2000 blocks, every notary node can mine on easy-level difficulty in a Komodo mining "free-for-all".

Komodo supports two separate but parallel chains: an asset chain and a main chain (a quasi-layer-two feature). Notary nodes maintain the main chain, but the asset chain can process significantly more transactions in a given time frame than the main chain. Asset developers shoulder the responsibility of bootstrapping a network of nodes to maintain the security of assets issued on the Komodo asset chain though.

BarterDEX is the Komodo blockchain's native decentralized exchange (DEX) that functions like any cryptocurrency exchange with order matching, liquidity provision, and transaction clearing. Jumblr is a transaction data anonymizing feature that serves as Komodo's primary tool for targeting on-chain privacy. As a Zcash fork, Komodo retained some of it's parent project's privacy features. But Jumblr relies on BarterDEX, KMD, and Zcash's parameters to attempt the level of security desired by the Komodo team.
