Here I tried to combine both proposals (dros’ structuring with opaceys’ writings):
Launched in July 2017, Particl (PART) is a decentralised, privacy-first eCommerce platform for goods and services.
Particl Marketplace runs as a peer-2-peer networked application rather than a website but has a familiar graphical interface for those using traditional eCommerce market platforms. Listings may be published globally or to private groups. There are no third parties between you and your buyer/seller, and payment can be made in any currency, though is settled in the native currency PART.
Particl Coin (PART) is needed to economically secure both the blockchain and the settlement of every marketplace purchase via an automated escrow system in which parties may be penalised if they fail to uphold their agreements. PART is using the PoS3 protocol on its independent blockchain, and is based on the latest Bitcoin Core source code with multiple additions to support the censorship resistant marketplace. These include Confidential Transactions with Bullet Proofs from the Blockstream Elements project (to hide tx amounts), Ring Signatures from CryptoNote/Monero (to hide party addresses), Cold Staking, Quantum Resistance and SMSG, a DHT embedded in the node stack for carrying rich data such as listings images and chat messages, without bloating the ledger.
