The Polymath platform opens up the blockchain to legally compliant securities offerings with a network of services designed to lower associated transaction costs over time. It provides a decentralized protocol for trading security tokens while enabling individuals and institutions to authenticate their identity, residency, and accreditation status to participate in a wide range of security token offerings (STOs). Legal delegates are also able to bid on new issuances to represent issuers on offerings to be done in a regulatory compliant manner. Issuers are matched with developers who can translate issuers’ Security Offering parameters into secure code that generates ERC20 compatible tokens. The polymath’s system can be modeled as tools for a set of participants, assets, marketplaces, and processes.
