Topl Technology

Driving Provable, Profitable Impact

Making impact provable and profitable is no small task. That’s why we’ve set out to build a unique blockchain custom designed to the task. Why use a general-purpose technology when you can use an Impactech system built for impact?

Impact Specific

Not all blockchains are created equal, and Topl is the only impact-specific blockchain. Our technology stack can be found at the unique intersection of deep, cutting-edge technology and positive impact. We're not just a website or dApp built atop another blockchain.

We are providing an infrastructure to bring our vision of monetized impact to life. What’s more, the features that make our technology impact-specific also make it a better blockchain.

Not all blockchains are created equal. Topl first launched our blockchain network in 2018 after only 9 months and less than $250,000 spent. Compared to the standard timeline of 2+ years with costs that often exceed several million dollars, we were quite proud of our early accomplishment. Since then, we have improved the stability and usability of our network as well as developed novel functionalities and features.

For Developers

Blockchain Core

In a global society that increasingly prioritizes sustainability and positive impact, we recognize a critical role for an impact- and sector-specific blockchain technology to:

Enable
Transparency

Verify
Proof

Improve
Efficiency

Increase
Coordination

Our blockchain offers all of these advantages, while specifically targeting a major challenge in both enterprise blockchains and the impact sector—our network is built to empower and coordinate full participation from all involved actors, no matter how small.

Here's How
IT Works:

Flexible and secure

Like smart contracts, our Modular Chain Programs are verifiable and self-executing. Unlike smart contracts, they’re entirely modular, which means that logic and data can be separated and combined to optimize scalability, security, and simplicity.

Simplified traceability

Built using a UTXO (Unspent transaction output) model, Topl is designed to bring simplified traceability to the movement of funds, goods, and impact. Instead of just tracking balances, our blockchain is built to trace assets themselves.

Energy efficient and decentralized

Topl leverages the first provably secure Proof of Stake consensus protocol, Ouroboros Genesis, allowing our blockchain to forgo both the excessive energy consumption of Proof of Work and the centralized trust required in byzantine fault tolerant implementations.

Inclusive and accessible

As a result of the UTXO model and modular chain programs, Topl can be uniquely deployed so that every participant only handles blocks that are relevant to them, allowing our blockchain to remain lightweight and accessible across a spectrum of technology ability and access.

Constructs and API

The Topl blockchain is a core protocol upon which different impact applications can be built. Here's how that works:

External API

Building on top of Topl’s blockchain is as simple as building on top of any standard service developers rely on today. Our network is accessible through both JavaScript and Python client libraries.

SMart ASsets

Leveraging Topl’s MCP functionality, Smart Assets are flexible enough to represent and mirror everything from consumable assets like diamonds and productive capital assets such as farms to more abstract conceptions, including Impact Credits and identity cards.

Value-Based Transaction Fees

While most blockchains apply fees based on the volatile price of a native cryptocurrency, Topl’s blockchain collects fees at a constant rate of 0.25% of a transaction’s value. This simple system is designed to make our network more inclusive and accessible for  a larger diversity of smaller, marginalized actors.

TEchNOLOGY Stack

The lower two technology layers are the foundation upon which different impact applications can be built.

The Topl Blockchain is the underlying protocol and built specifically as a solution for the impact space. Our blockchain went live in 2018, and features and functionalities are constantly being built out.

Topl Services and Tooling is the suite of hosted services and tools that simplifies user interaction with the Topl blockchain and ensures that usage of our technology is as simple as using any other API accessible we service available today.

Features

Modular chain programs

Like smart contracts, our Modular Chain Programs are verifiable and self-executing. Unlike smart contracts, they’re entirely modular, which means that logic and data can be separated and combined to optimize scalability, security, and simplicity.

UTXO Transaction Model

Built using a UTXO (Unspent transaction output) model, Topl is designed to bring simplified traceability to the movement of funds, goods, and impact. Instead of just tracking balances, our blockchain is built to trace assets themselves.

Secure and Efficient POS

Topl leverages the third generation provably secure Proof of Stake consensus protocol, Ouroboros Genesis. Ouroboros Genesis allows our blockchain to forgo both the excessive energy consumption of Proof of Work and the centralized trust required in practical byzantine fault tolerant implementations.

Emergent Sharding

As a result of the UTXO model and modular chain programs, Topl can be uniquely deployed so that every participant only handles blocks that are relevant to them, allowing our blockchain to remain lightweight and accessible across a spectrum of technology ability and access.

Leveraging Topl’s MCP functionality, Smart Assets are flexible enough to represent and mirror everything from consumable assets like diamonds and productive capital assets like farms to more abstract conceptions, including carbon credits and identity cards.

Value-Based Transaction Fees

While most blockchains apply fees based on the volatile price of a native cryptocurrency, Topl’s blockchain applies a transaction fee every time an asset is created or transferred, depending on the value of the asset being tracked. This system is designed to make our network more inclusive and accessible for a larger diversity of smaller actors.
