# Technology

The mlayer blockchain is purpose built application developed to serve as the backbone of our novel decentralized programable communication infrastructure. mLayers communication layer is a distributed logic clock whose state, s, at any given time, *t* is validated by maintaining and tracking causal relationship, *r,* between events, *E,* that trigger state changes, ∆s within a given Subnet, *Sn.*

### Components of the communication layer

**Subnets:** They represent isolated environments within which individual state machines exist. Each subnet created represents an application or product within the network. Example, a developer creating a decentralized Uber application will do this within a dedicated subnet.

**Accounts:** These are cryptographic key that identify a user of the network

**Agents:** Agents are key peers authorized to act on behalf of an account. They can be uploaded to applications and devices to perform action on behalf of the parent account.

**Topics:** Topics represent communication channels within a subnet. Topics receive messages as events.

**Smartlet:** WASM script that intercept, analyze and process message/events. The are capable of routing messages to AI agents. Smartlets can be utilized as validators, extractors, transformers and data loaders into the secondary state store

**Secondary State Stores:** They are data stores dedicated to each subnet. They can be used to store arbitrary data or account specific state data.

**State Proof:** State proofs are generated by random participating nodes based on a fibronacci sequence and verified on blockchain using aggregate schnorr proofs
