What is Polymesh? The Purpose-Built Blockchain for Regulated Assets

From Smart Contract to Dedicated Blockchain

In the early days of the security token industry (circa 2017-2019), Polymath attempted to force regulatory compliance onto the Ethereum blockchain using the ST-20 standard. While innovative, this approach faced significant hurdles: Ethereum’s anonymity, lack of finalized settlement, and the risk of “forks” (network splits) made it difficult for large institutions to adopt.

To solve these fundamental issues, the team behind Polymath launched Polymesh in 2021. Unlike Ethereum, which is a general-purpose chain for everything from gaming to DeFi, Polymesh is a specialized Layer 1 blockchain built exclusively for regulated assets.

The 5 Pillars of Polymesh

Polymesh was designed to solve five specific challenges that prevented Wall Street from using public blockchains:

1. Identity

On Ethereum, anyone can create a wallet. On Polymesh, every user must pass a verified identity check—known as Customer Due Diligence (CDD)—before they can even hold a token. This ensures that all participants on the network are known entities, eliminating the risk of interacting with sanctioned wallets.

2. Governance

Public chains often suffer from chaotic governance (e.g., the DAO hack or the Bitcoin Cash hard fork). Polymesh uses a governance council to ensure the network cannot fork. This guarantees that an asset, like a tokenized stock, will not suddenly duplicate into two different versions.

3. Compliance

Instead of relying on complex smart contracts to enforce rules, compliance is baked into the blockchain’s base layer. Issuers can set rules (e.g., “Only accredited investors from the US can buy this”) that are enforced automatically by the network protocol itself.

4. Confidentiality

Institutions need privacy. Polymesh allows for confidential asset transfers where the amount and type of asset can be hidden from the public, while still remaining auditable by regulators.

5. Settlement

Transactions on Polymesh provide “deterministic finality.” This means that once a trade is confirmed, it is legally final and cannot be reversed by a network reorganization, a critical requirement for legal settlement.

The Migration: POLY to POLYX

With the launch of the new chain, the old utility token (POLY) was upgraded to the native fuel of the new network: POLYX.

• POLY (Ethereum): Used essentially as a coupon to pay for services.

• POLYX (Polymesh): Used to pay for transaction fees (gas) and to secure the network via Staking.

Summary

Polymesh represents the maturation of the security token industry. It acknowledges that while “code is law” works for crypto, “law is law” for securities. By building a permissioned, identity-centric blockchain, Polymesh provides the infrastructure necessary for banks and institutions to tokenize real-world assets safely.
