The Latest from OurPhone - Threefold

🔗What is Peer-to-Peer?

Peer-to-peer (P2P) is a term that originated from the distributed computer application architecture where tasks and workloads are shared between peers, popularized by Napster, a revolutionary file storing system from the late 1990s.

The concept inspired new structures and philosophies in many areas of human interaction. P2P systems and groups are typically critical of authoritarian and centralized social structures and believe in equality, meritocracy, flat systems, participatory & circular economies, as the concept represents a concrete pathway to these outcomes or visions.

P2P systems are network, not linear or 'pyramidal' hierarchies (though they may share some elements). They are 'distributed', though they may have elements of 'centralization' and 'decentralization.' And intelligence is not located at any center, but everywhere within the system.

🔗How does ThreeFold relate to peer-to-peer?

ThreeFold's Peer-to-Peer (P2P) computing network is a distributed architecture that splits tasks and workloads between its peers, ThreeFold Farmers. Farmers are equal participants in the network and together they form a peer-to-peer network of nodes, the ThreeFold Grid.

Farmers make their resources, such as processing power, disk storage or network bandwidth, directly available to other network participants, without the need for central coordination by servers or stable hosts. Farmers are both suppliers and consumers of resources, in contrast to the traditional client-server model in which the consumption and supply of resources is divided.

In the near future, ThreeFold will create Digital Twin, which will go beyond the era of peers doing similar things while sharing resources. It will actually enable much more than that. Digital Twin will create a complete new digital world with diverse peers that can bring in unique resources and capabilities to a virtual community on the ThreeFold Grid. This will empower the network of peers to engage in greater tasks beyond those that can be accomplished by individual peers, and are beneficial to all the peers.

🔗Why did ThreeFold choose peer-to-peer? 

Everything starts (or should start) from the why, and the ThreeFold story started a long time ago. Before the inception of ThreeFold, many of the co-founders of the project used to work with the largest IT & Cloud actors. Throughout their experience working in the Industry, they realized that the complexity of the technology and the centralization of knowledge & power led to an inefficient, unsustainable, not scalable and unequally distributed infrastructure. So they decided to redesign the whole Internet and cloud infrastructure bottom-up with the vision of shaping a global internet economy that can scale anywhere efficiently, cost efficiently and sustainably. 

🔗Why does the world needs peer-to-peer? 

By developing the technology, the conviction that peer-to-peer was the best solution for humanity and the planet strengthened itself. Why? Well, put simply, a peer-to-peer system removes all forms of intermediaries, unnecessary steps and complexity from the picture. Therefore, it simplifies the architecture in an incredible way. The benefits are many but here are the most popular benefits:

• Privacy: Our peer-to-peer environment means no middlemen or intermediaries, meaning data travels directly between peers and stored on the nodes of their choice rather than being sent through and stored by a third party.
• Security: Data stored in data centers is susceptible to security breaches. In bypassing data centers and exchanging data directly between peers, we can achieve much greater security as it reduces code and back doors significantly. 
• Scalability: In a many-to-many system, scale is essentially unlimited. There is simply no bottleneck. And hardware (nodes) can be added at ease compared to current data center model.
• Cost-efficiency & Sustainability: End-to-end (direct) connection between peers means a more efficient path for data and less energy is needed. Less energy means less cost, and less harm to our planet.

🔗In 2021 the world is going peer-to-peer! 

We're now in 4 years into the project, and it is clear that ThreeFold holds the most advanced technology and is probably the only tech company in the world that can achieve a peer-to-peer network & digital world as envisioned by the concept authors. The ThreeFold Grid is running and already at it's 2.4 version and 2021 will bring various commercial opportunities for the public to partake in the peer-to-peer network, from hosting IT workloads to experiencing P2P end-user solutions. In other words, in 2021, the world will be able to go peer-to-peer.

🔗Simplicity is the key to unlock a better future

Over time, integration suites, middleware solutions, and enterprise service busses have been invented and implemented to cover integration challenges within the current internet. This has further complicated IT architectures, resulting in a loss of actual end user workload performance.

ThreeFold reworked the whole approach to IT architectures and eliminated the layers of complexity. The result is a cloud stack that presents minimal overhead and that requires less hardware – reducing heat generation and eventually cooling requirements. By reducing the need for power, the net result is an energy-efficient Internet grid.

🔗Improving resilience and efficiency through Self-Healing IT

Keeping systems up and running is a major requirement in modern day IT. Leading vendors earn most of their margin by selling maintenance contracts, performance guarantees, and professional services. Their business models bring no incentive to make things simple and efficient for consumers.

Creating a self-healing environment requires only minimal manual intervention to replace broken hardware components. Broken hardware components are inevitable, and the Zero-OS distributed node architecture deals with such failures by turning off broken components and provisioning unused capacity. By removing the need to ship broken parts back and forth, and linking to the corresponding installation knowledge (engineers), a lower carbon footprint can be achieved.

🔗“No painkiller” approach. We tackle the root issue

If a specific piece of software or hardware is not delivering the required performance or reliability, we should analyze the core design/algorithm and its usage of soft/hard components to determine the root causes of persistent issues to be solved.

Currently, most storage vendors follow the path of least resistance when trying to improve on performance. Their solution for meeting performance targets is to use faster components (CPU, memory, network card, proprietary acceleration) rather than looking at the core algorithms that drive the utilization of those components. Swapping components for faster ones perpetuates a cycle of cutting corners and focuses reliance on innovation from hardware component providers rather than solving the more fundamental and underlying issues. That's a "painkiller" approach.

Zero-OS was designed to solve root problem issues by design. While still using high-performance hardware components on the ThreeFold Grid, the algorithm of Zero-OS maximizes utilization possibilities. This enables greater performance and sustainability. Some key examples how this is achieved:

🔗Eliminating unnecessary elements from standard architectures

Virtualization adds a layer of software between the actual end-user workload and physical hardware. It also allows for multiple workloads to run on the same hardware by using excess capacity. There is definitely merit in building a virtualization solution. Building an effective virtualization solution that does not require abundant context switching is key and this is why Zero-OS has been developed. Zero-OS uses a minimal Linux kernel that allows for a number of user spaces to co-exist. In these user spaces, containerized versions of software can be run, eliminating the need for hypervisors, virtual OS to fuel the virtual machines, and guest operating systems. This also minimizes the required overhead for the host OS.

🔗Minimizing network connections usage

Supercomputing delivered many new technologies. But, not all of them are usable solutions for everyday workloads. One technology invented to make supercomputers performant is the use of Remote Direct Memory Access (RDMA). RDMA allowed physical CPU boards (containing both CPUs and memory) to access other CPU boards in memory stored data over a dedicated channel. This eliminated the need to transport data between CPU nodes over network connections (or other mainstream means to exchange data). The result was a considerable reduction in overhead created when allowing distributed end user workloads to operate over multiple physical cores. The leading server and storage solutions brands have never considered nor implemented such mechanisms. This resulted in an increased need for faster networks - increasing complexity, costs, efforts and resources needed to operate solutions.

RDMA is only used in certified farms and requires involvement of TFTech.

🔗Minimizing disk usage

The storage solution uses slow and big (the bigger the better) HDD disks which drive in rack density. As they spin slower they consume less power and need less cooling. But then, how can you deal with read/write intensive workloads? The storage algorithm uses a SSD cache to acknowledge Inputs/Outputs coming from the applications, fills the erasure coded data blocks in large (up to 64MB) storage containers and writes the big chunks of data on the big and slow HHDs. If you are familiar with HDD disks, you know they like to be streamed on instead of having a lot of small bits written in a scratchy way.

Continuous innovation in all of these areas are leading to an efficient technology stack.
