EOS is a Layer 1 blockchain infrastructure and high-throughput transaction engine. It serves as a WebAssembly smart contract platform that manages state transitions and network consensus across a peer-to-peer network. The system utilizes a sandboxed virtual machine for executing smart contract logic and employs a Byzantine Fault Tolerant delegated proof-of-stake consensus mechanism to finalize the global ledger state. It features a resource-based stake model for CPU and memory allocation and an asynchronous messaging system for inter-contract communication to prevent recursive call overflows.

go-ipfs is an implementation of an IPFS node, providing a distributed filesystem and a content-addressable storage system. It enables the storage and retrieval of data based on unique cryptographic hashes rather than fixed network locations, allowing files to be shared across a peer-to-peer network without a central authority. The system utilizes a distributed hash table and a peer-to-peer gossip protocol to route requests and propagate network state and metadata. It organizes data using a Merkle DAG structure to support efficient deduplication and versioning of content. Capabilities include

Quorum is a permissioned blockchain framework based on Ethereum, designed for enterprise consortia. It implements a private version of the ledger that restricts network access to authorized participants and uses authority-based consensus mechanisms to achieve transaction finality without energy-intensive mining. The project focuses on data privacy and access control through the use of private smart contracts and encrypted state storage. This ensures that transaction visibility and business logic results remain hidden from unauthorized nodes and are only accessible to designated consortium mem

The Metaverse individual chain service ETP coin and immutable data space for Hyperspace.

Sui is a blockchain platform featuring an object-centric state model and resource-oriented smart contracts. It utilizes parallel transaction execution to increase network throughput and supports programmable transaction blocks that bundle multiple operations into single atomic units. The platform distinguishes itself with a capability-based access control system and zero-knowledge login mechanisms, enabling users to authenticate via identity providers without seed phrases. It also implements deterministic object addressing to allow predictable state lookups and supports the creation of soulbo
