OCP introduces an innovative relayer mechanism that seamlessly connects applications to a modular permissionless custody protocol. OCP operates a protocol that acts akin to a mesh network, enabling an end-user to leverage a diverse set of key management protocols. We call this “Keychain Aggregation”. Building a protocol that solves for Keychain Aggregation not only simplifies the way developers can build, abstracting risk and complexity, but it also harmonizes and aggregates the economics associated with having multiple bilateral commercial relationships.

With OCP, we have a new custody primitive that embraces (1) modularity, in connecting key management solutions, and (2) decentralisation, in the way users can access key generation and transaction signing services. We are particularly excited to pioneer this, witnessing existing security and custody solutions struggle to adapt to the ongoing proliferation of chains. Additionally, with the impending tokenization of Real World Assets (RWAs) - potentially mobilizing over trillions of dollars into the blockchain ecosystem - the demand for versatile and modular solutions is clear and present.

OriginTrail is an ecosystem building a trusted knowledge infrastructure for artificial intelligence. It addresses the challenge of misinformation in the AI era by ensuring the origin of information and enabling discoverability of the world's most important knowledge and real world assets (RWAs).

OriginTrail is creating a Verifiable Web for decentralized AI by empowering world class brands and builders. It utilizes its unique Decentralized Knowledge Graph and OriginTrail Parachain to deliver AI-powered search and solutions for enterprises and individuals worldwide.

OriginTrail has gained support and partnerships with world-class organizations such as British Standards Institution, SCAN, Polkadot, Parity, Walmart, World Federation of Hemophilia, Oracle, and the EU Commission's Next Generation Internet. These partnerships contribute to advancing OriginTrail's trusted knowledge foundation and its applicability in trillion-dollar industries, while providing a verifiable web of knowledge important in particular to drive the economies of RWAs.

The best way to see the technology in action is by checking ChatDKG, which is an experimental, question answering bot on X (Twitter) based on trusted Knowledge Assets in OriginTrail Decentralized Knowledge Graph. The ChatDKG provides answers based on OriginTrail trusted AI.

The Metcalfe phase of the updated roadmap pursues an ambitious goal of creating the world’s largest verifiable web for AI consisting of 100 billion Knowledge Assets, bringing a 100.000x scalability increase. As the name of the phase suggests, it will seek to produce network effects across the OriginTrail DKG and use novel techniques to pursue autonomous DKG growth based on the genesis knowledge foundation being created by organizations and individuals alike. The genesis part of the Metcalfe’s phase also introduces knowledge mining and knowledge signaling capabilities to drive constant growth of the Verifiable Web.

Following the Genesis stage and the transition to an AI-native V8, further capabilities will become available in the Convergence stage. By leveraging the advancements in AI and the DKG, we will unlock autonomous knowledge mining which in turn leads to an autonomous DKG. At that stage, new knowledge gets added to the DKG with very limited human involvement. Services such as AI agents will be performing knowledge inferencing directly on the DKG to find any “blind spots” in the knowledge they can fill as well as search for new knowledge and bring it to the DKG in accordance with knowledge signaling.

Fantom is a directed acyclic graph (DAG) smart contract platform providing decentralized finance (DeFi) services to developers using its own bespoke consensus algorithm.

Together with its in-house token FTM, Fantom aims to solve problems associated with smart-contract platforms, specifically transaction speed, which developers say they have reduced to under two seconds.

The Fantom Foundation, which oversees the Fantom product offering, was originally created in 2018, with the launch of OPERA, Fantom’s mainnet, coming in December 2019.

Fantom is an open-source decentralized smart contract platform for DApps and digital assets that was created as an alternative to Ethereum. Fantom has the goal of overcoming the limitations of previous generation blockchains and balancing three components: scalability, security and decentralization. The project offers a set of tools to simplify the process of integrating existing DApps, as well as a detailed staking reward system and built-in DeFi instruments.

Fantom is a Layer-1 blockchain that uses a scratch-built consensus mechanism and independent consensus layer, Lachesis, to facilitate DeFi and related services on the basis of smart contracts. Lachesis provides security for other layers as well, including Opera, Fantom's EVM-compatible smart contract chain. The long-playing mission of the project is to “grant compatibility between all transaction bodies around the world.”

One of Fantom's key strengths is its performance and efficient transaction processing, namely thousands of transactions per second, where transactions are settled in 1-2 seconds, and the cost is fractions of a cent per transaction. As a result, Fantom provides higher scalability but at a lower cost.

The ecosystem is based on two main technologies: Lachesis protocol and Opera.

The Lachesis protocol is the core consensus layer that secures the Fantom network by providing both transaction speed and security.

Lachesis is an aBFT consensus engine that uses a directed acyclic graph (DAG) algorithm. How it works: network data can be processed at different times, and the network filters the participants, allowing only one third, which are allocated due to erroneous or malicious behavior, without compromising network processes.

Fantom's Asynchronous Byzantine Fault Tolerant (aBFT) Proof-of-Stake (PoS) consensus mechanism maintains the efficiency of the entire network, its design provides security at maximum speed. Fantom developers emphasize that the PoS mechanism is a leaderless phenomenon — there are no leaders of blocks and participants, and anyone can join (or leave) the network of nodes at a convenient moment.

The key qualities of Lachesis are: asynchronous, leaderless, Byzantine fault-tolerant, and near-instant finality.

As for Opera, it's an application development layer or Fantom's mainnet deployment platform, permissionless and open-source hosting DApps. Thanks to EVM integration and support for the Solidity programming language, Fantom has a full set of smart contract capabilities, which allows users to seamlessly interact with Ethereum platforms while maintaining the advantage of Fantom's transaction efficiency.

The Fantom Foundation concluded that removing block leaders improves network security, so Opera uses a PoS model and leaderless validators (validators do not determine which blocks are valid).

In addition to being a fast, secure and cheap payment platform that enables to make fast and secure payments at minimal cost, Fantom also features on-chain governance where users vote with FTM tokens (one token equals one vote). Of the features: users have the right to express the degree of agreement / disagreement on a scale from 0 to 4.

FTM is the native utility in-house PoS token of Fantom that powers the ecosystem and is applied for payments, network fees, staking, and governance. FTM forms the backbone of transactions, and allows fee collection and staking activities, along with the user rewards the latter represents.
