IOTA
IOTAFeeless distributed ledger designed for machine-to-machine transactions
Technology Stack
Introduction to IOTA
IOTA is a distributed ledger designed for the Internet of Things (IoT), featuring feeless transactions and a unique DAG-based architecture called the Tangle. Unlike traditional blockchains, IOTA was purpose-built for machine-to-machine micropayments and data transfer.
Founded by David Sønstebø and Dominik Schiener, IOTA targets a future where billions of devices transact autonomously. The feeless nature enables microtransactions that would be economically impossible on fee-based blockchains, essential for IoT use cases.
The Tangle: DAG Architecture
Beyond Blockchain
Different structure:
- Directed Acyclic Graph (DAG)
- No blocks
- No miners
- Parallel transactions
How It Works
Transaction validation:
- Each transaction approves two previous
- Self-validating network
- No fees possible
- Scalable by design
Theoretical Benefits
Design advantages:
- Feeless transactions
- Scalability with usage
- No miners needed
- Micropayment friendly
How IOTA Works
Transaction Flow
Process:
- Create transaction
- Select two to approve
- Do small PoW (spam protection)
- Broadcast to network
- Transaction confirmed
Coordinator (Historical)
Training wheels:
- Centralized coordinator
- Milestone confirmations
- Security guarantee
- Removed with Stardust
Current Architecture
IOTA 2.0 direction:
- Coordinator-free goal
- Decentralized consensus
- Modular architecture
- Smart contract support

Conclusion
IOTA represents an ambitious attempt to build infrastructure specifically for machine-to-machine economies, with feeless transactions enabling micropayments impossible on traditional blockchains. The Tangle architecture offers theoretical advantages for IoT use cases.
The long development history and coordinator removal journey have tested community patience, but technical progress continues. The Shimmer staging network enables ecosystem development while mainnet evolves.
For IoT applications requiring feeless micropayments and for developers interested in DAG technology, IOTA provides purpose-built infrastructure. Success depends on completing decentralization and demonstrating real-world IoT adoption at scale.
