Since the launch of ThreeFold Grid 3.0, TFT has been available on three blockchains – Stellar, Binance Smart Chain and the Substrate-based ThreeFold Blockchain (aka TF Chain).

There are already active bridges that connect Stellar to Binance Smart Chain and TF Chain, improving the accessibility and availability of TFT, while also connecting the ThreeFold ecosystem to external blockchain networks.

Learn more about TF Chain in our blog post here.

What are bridges and why are they important?

The concept of bridges in crypto is similar to a bridge in the physical world. Bridges in the real world simply connect two different locations and communities so that the people can travel back and forth and resources can be exchanged freely.

Similarly, using bridges in blockchain allows users to easily transfer tokens and other crypto assets between two or more networks – regardless of the different protocols, tooling, and governance models these networks have. Simply put, a bridge ensures a secure interoperability between different blockchains.

ThreeFold uses blockchain bridges to connect external blockchain networks to the ThreeFold ecosystem. The bridging mechanisms we’ve implemented allow TFT to be transferred securely between different blockchains. Currently, we’ve established two 2-way bridges:

• Stellar <> Binance Smart Chain
• Stellar <> TF Chain

But what is the difference between the 3 chains?

Stellar is an open-source network for storing and moving digital assets, and still remains the main blockchain for the minting of TFT and distribution of farming rewards. Until the launch of TF Chain with Grid 3.0, only TFT living on Stellar were accepted for the reservation of Internet capacity on the ThreeFold Grid. 

Binance Smart Chain (BSC) is a standalone, parallel Binance chain that is a leading DeFi ecosystem next to Ethereum. On BSC, TFT is implemented as a cross-chain asset, allowing anyone to connect to the bridge using Metamask or Trust Wallet – the most popular Web 3 wallets in the world.

TF Chain was built on the Substrate framework with the purpose of decentralizing user-farmer relationships on the ThreeFold Grid. It has its own native form of TFT, which can be bridged back and forth from Stellar-based TFT. This model will be implemented for other chains in the future, for interoperability and cross-chain features between blockchain and DeFi ecosystems and the ThreeFold Grid.

What’s new with TF Chain?

TF Chain represents a leap forward for simplicity in payments for capacity reservations and a move towards greater decentralization of the systems that support the ThreeFold Grid. With the launch of ThreeFold Grid 3.0, TF Chain became the official record of ThreeFold farms and nodes, and brought peer-to-peer billing based on smart contracts for workload deployments on the ThreeFold Grid. 

For now, minting will remain on Stellar but reservations of nodes and capacity on ThreeFold Grid 3.0 are already executed via TF Chain. Bridges were established between Stellar and TF Chain to facilitate payments, e.g. if you pay for a workload deployment in Stellar TFT, this payment needs to be bridged to TF  Chain’s native TFT to fund the smart contract.

The two-way bridge between Stellar & BSC 

Until recently, the bridge between Stellar and Binance Smart Chain (BSC) was one-way only: from BSC to Stellar. Even though it was possible to transfer TFT from Stellar to BSC via  command line, this was only an option for tech-savvy people. Now, you can also deposit TFT from Stellar to BSC using the bridge with a proper UI, as you can see in the image below.

When depositing from TFT Stellar, please be sure that both addresses and memo are as indicated in the instructions or the TFT you transfer will be lost forever. To facilitate the process, a QR code is generated and can be scanned using the ThreeFold Connect app, automatically filling in the right address and memo on your behalf.

As Binance Smart Chain is a more expensive chain, a fee of 50 TFT will be automatically charged for the bridge from Stellar to BSC. Find the full step-by-step guide for the Stellar-BSC bridge here. 

What’s next? 

As the ThreeFold ecosystem continues to grow, we’re looking into building more bridges (e.g. Cosmos, Ethereum) to improve the accessibility of TFT and simplify the onboarding of blockchain and DeFi projects on the ThreeFold Grid. TF Chain will play an important role in the further development of the People’s Internet, so give our blog post on TF Chain a read here.

The third release of the ThreeFold Grid represents a major step in the decentralization of the People’s Internet with the Smart Contract for IT coming to life on the ThreeFold Blockchain (aka “TF Chain”). Built on the Substrate framework, TF Chain represents the layer-0 for all current and future technologies to provision decentralized Internet capacity. 

But what is Substrate to begin with? And what exactly does our TF Chain do?

What is TF Chain and what is Substrate?

TF Chain is the universal smart contract layer on the ThreeFold Grid. It’s an application-specific blockchain customized for the operation of a single application – provisioning decentralized compute, storage and network capacity. 

Substrate is a blockchain-building framework from Parity that allows developers to simply create future-proof solo blockchains or parachains for any use case. Parity was founded by Ethereum’s co-founder and first CTO Gavin Wood in 2015, and went on to develop Substrate to power a multichain, interoperable and decentralized Internet.

Why did we choose Substrate for our TF Chain?

Substrate brings clear benefits to TF Chain in relation to its frameworks for developers, its interoperability with other blockchain ecosystems and its huge community. More than 150 projects from NFTs to DeFi are already building on it.  

By providing a solid, mature and secure layer for custom blockchains, Substrate is built for adoption. The blockchain framework was built with the programming language Rust and is modular by design. Choosing Substrate allowed our developer team to leverage great blockchain constructs and efficiently build TF Chain instead of re-inventing the wheel. 

Its flexible, modular and composable architecture enables our team to focus on what matters the most – the unique demands of ThreeFold Grid. For example, we’ve built  a Grid module with specific functionalities for farms and nodes. Just like a chef can invent a new recipe and add it to a menu, Substrate allows our developers to build and add as many custom functionalities to TF Chain as we’d like, in a fully decentralized way. 

A major benefit that comes with TF Chain being built on Substrate is the native compatibility with the Polkadot ecosystem, opening up the opportunity for ThreeFold to become a parachain on the Polkadot network and seamlessly bridging to other Substrate-based chains in the future.

What’s the purpose of TF Chain?

For ThreeFold to be a truly decentralized peer-to-peer Internet infrastructure, people should be able to use Internet infrastructures from anywhere without any intermediaries like AWS. TF Chain serves exactly that purpose. 

It orchestrates the provisioning of compute, storage and network on the ThreeFold Grid via Zero-OS, removing all forms of intermediaries present in today’s centralized IT infrastructures. Put simply, TF Chain allows people to provide and use cloud resources in a 100% decentralized way. 

What does TF Chain do?

TF Chain is responsible for achieving consensus on all Internet capacity transactions on the ThreeFold Grid and to store them in a historical record. This prevents users from “double spending” their ThreeFold Tokens and ensures the correct execution of Internet capacity provisioning via smart contracts, while also protecting the network from potential attacks. 

An exciting feature that comes with TF Chain 3.0 is a totally new peer-to-peer billing framework for Internet capacity provisioning and workload deployment. This module allows for all functionalities of the ThreeFold Grid to be provisioned peer-to-peer between users and farmers. Therefore, the ThreeFold Token now also lives on the Polkadot network, allowing it to bridge back and forth from the Stellar network and potentially from other chains in the future.

While TF Chain builds on the Substrate framework, most of its functionalities are custom-built to fit the specific needs of the ThreeFold Grid – from Internet capacity provisioning, workload deployments, and payment and billing processes, to digital twin creation and much more. By executing all these actions via smart contracts in an automated and decentralized way, the activity on the ThreeFold Grid is always secured by blockchain technology and available to other users for open collaboration. 

Farms can now be registered on our new TF Chain Portal!

The Future

While Internet capacity provisioning and workload deployments are already executed via TF Chain, the minting of TFT according to the Proof-of-Capacity algorithm remains on the Stellar blockchain for now.

Building our own application-specific blockchain represents a major step towards decentralizing the ThreeFold Grid and ecosystem – a massive thank you to our developer team for this great achievement! 🙏

Tim Berners-Lee created the web server and browser in 1990. Back then, the web was of a free, rather decentralized nature in which no single entity was to control the access to it. With the client-server architecture of the web, however, centralization came about. Nowadays, the web as well as the Internet in general are highly centralized. There are only a few companies acting as gatekeepers to large parts of today’s Internet. The Internet as we know it is continuously struggling with issues related to its centralized nature – from censorship and attacks on net neutrality to manipulation attempts from companies with monopolistic power. These issues are systematic and major players like Amazon or Facebook are benefitting from the situation as it is. This business model is also highly reliant on centralized hyperscale data centers that also come with a whole set of issues, from their vulnerability and limited scalability to their extremely high energy consumption and more.

People have become the product of a business model where companies offer their services in exchange for personal data – in order to capitalize on and exploit the data, basically squeezing people out for their data like oranges for juice. In times where data exploitation is the norm, it makes sense that data is often referred to as digital oil or gold. Moreover, algorithms of social media platforms increasingly lead to content provoking controversy and addictive engagement as this type of content tends to increase the time people spend on the platforms – with shocking impacts like The Wall Street Journals’ investigation “The Facebook Files” and The New York Times’ audio series Rabbit Hole show.

All of these issues have strengthened the push towards decentralization, mainly associated with the blockchain technology and cryptocurrencies like Bitcoin. However, many of the projects in the decentralized space still rely on centralized providers or structures to some degree. The second most-popular blockchain in the world, Ethereum, for example, has 60% of its nodes run on centralized cloud providers with 25% of them running on Amazon Web Services (AWS). Akash, a blockchain-based cloud computing platform, prevents unutilized capacity from centralized cloud computing services from going to waste. Leveraging this underutilized cloud capacity, however, also causes Akash to be highly dependent on centralized capacity. Dfinity’s platform for decentralized apps (dApps) is based on an ecosystem of independent data centers, which makes it rather centralized on an infrastructural level.

While the previously mentioned projects are all seeking to push decentralization, they all have one thing in common: they rely on centralized structures or providers at least to some degree and therefore, are not fully decentralized yet. So, what does true decentralization look like?

How ThreeFold is Changing the Game

It is our mission to transform the Internet and Cloud and to create borderless opportunities for humanity. Therefore, we‘re truly committed to decentralizing the infrastructure behind the Internet to scale current and future digital workloads. At Threefold, we’re building an entirely new infrastructure from the ground up, starting with a Grid of new, neutral capacity and our operating system Zero-OS. Our ThreeFold Grid, based on open-source technology, enables an autonomous, secure, and energy-efficient infrastructure that allows for unlimited scalability while remaining affordable. Our Grid is the largest and most advanced peer-to-peer infrastructure in the world, already available in more than 50 countries and keeps expanding fast. With our energy-efficient full stack cloud infrastructure, uniting compute, storage, and network, we are much more comprehensive than other projects.

At ThreeFold, we believe in giving power to the people by developing technologies that empower individuals, enable social participation, and foster collaboration. We’re enabling even people without technical skills to join the network with plug-and-play 3Nodes offered through our certified hardware partners. The ThreeFold Grid is therefore more inclusive and allows any individual to participate. Our peer-to-peer nature removes the need of centralized servers and any type of intermediary, allowing applications and data to live closer to where they’re being utilized.

In addition to that, we believe that no one but you should own your data. Our technology empowers every user to be data sovereign, giving them full control over their own data by using a variety of innovative technologies, such as autonomous IT, blockchain, and peer-to-peer networking. This way, our technology is turning traditional IT upside down, enabling a data-sovereign Internet that gives users control and ownership of their data in an entirely secure, peer-to-peer IT ecosystem.

All in all, we provide the low-level primitives for a decentralized world, enabling any project to run on a fully decentralized, energy-efficient, and self-healing infrastructure. As we truly believe in collaboration to effect change at a large scale to fully decentralize the Internet and Cloud, our partnership ecosystem keeps growing. Most recently, we announced a strategic partnership with ownCloud, an alternative to public clouds with more than 200 million users worldwide, that aims to advance the decentralization of the consumer cloud.

So, we’d like to invite you to join forces with us to further push the decentralization of the Internet together – whether by becoming a 3Node or building on our ThreeFold Grid, by buying our ThreeFold Token (TFT), our currency for a decentralized world, or by testing our P2P Cloud. Let’s revolutionize the Internet together!

An example to illustrate this challenge is the fact that up to 60% of Ethereum (the world’s second most-popular blockchain) nodes run on centralized cloud providers and 25% of them run on Amazon Web Services (AWS).

While the topic is being addressed, it isn’t being solved at scale. The good news is that ThreeFold can play a large part in solving it.

Why should blockchains make this move?

The blockchain movement, as mentioned, is very heavily tied to the movement around decentralization. Cryptocurrencies represent the move away from centralized banks as the authorities and gatekeepers around money – just as ThreeFold and similar projects represent the move away from centralized clouds as the authorities and gatekeepers around data. The thing is, if blockchains are to rely on centralized cloud for hosting, they aren’t truly embodying decentralization.

Understandably, many blockchains have chosen centralized cloud providers in the past because there wasn’t much of an alternative. But now, the Decentralized Cloud (DeCloud) movement has changed all of that.

Here is how some specific audiences can benefit:

For Node Operators

Any full node or validator node can run on ThreeFold’s Peer-to-Peer (P2P) Cloud, making that particular Blockchain even more community-owned, and more decentralized from an IT/cloud level. Any node operator can choose to run their nodes from any farmer location on the ThreeFold Grid, totally peer-to-peer between the chosen farmer and the node operator. The deployed workloads are computed in a P2P manner, no middle party involved.

For dApp Developers

Web3/Blockchain developers can use ThreeFold’s P2P Cloud - offering both compute and storage - to build and power their applications in a truly decentralized cloud infrastructure, both blockchain-native and cloud-native. A strong advantage here is that developers have the ability to leverage Kubernetes, Docker, S3, and other cloud-native tools (all compatible / integrated with the ThreeFold) to power and optimize their data processing capabilities, as well as the overall functionality of their dApps. But the sweet spot is that it is deployed on a decentralized IT infrastructure, close to where users would be located.

But why choose ThreeFold over other DeCloud projects?

There may be bigger names in the space, but ThreeFold’s technology and offerings are much more comprehensive than the rest. ThreeFold provides decentralized storage, compute, and network all under one roof (whereas most other projects offer only one of the three) and as mentioned, we have created an environment for developers which is highly-compatible to the developer tools and solutions they use today. Further, ThreeFold is building new infrastructure from the ground up (rather than relying on extra space in data centers) and the technology is truly peer-to-peer.

We already have a number of partners in the space who recognize these advantages.

Any blockchain protocol or dApp, whether operating DeFi, NFTs, DEXs, etc, will at some point need to leverage the power of the decentralized cloud and escape from centralized cloud providers. We’re seeing some of that adoption from a decentralized storage side with IPFS, which has been adopted by many dApps, and others – but as a developer, you will have to think twice, not just about where your/your users’ data is being stored, but also about how (and where) your app is computed and powered.
