Particle Network, a modular blockchain, has raised $15 million in a Series A funding round led by Spartan Group and Gumi Cryptos Capital, with participation from SevenX Ventures, Morningstar Ventures, Flow Traders, HashKey Capital, and others. Particle Network is currently in the first phase of the testnet and is said to have registered about 1.30 million common accounts and over 114 million transactions. Particle Network's second phase of the testnet is expected to launch this week, with the mainnet scheduled to launch in the third quarter of this year. Particle token PARTI will also be launched at the same time as the mainnet. With the new round of funding in place, Particle hopes to expand the team size from its current 30 + people to 40 +.
