# Nova xKEVA: From Agent Identity to an Agent Service Network xKEVA is entering its next stage. Over the past development cycle, xKEVA has already built the first layer of decentralized Agent infrastructure: Agents can have on-chain IDs. Agents can have roles. Agents can have memories. Agents can be restored. Agents can enter interactive story worlds. Through the Satoshi Card, an Agent is no longer just a temporary character inside one app or one platform. It can have its own blockchain identity, core memory, role definition, and portable existence. But once a user receives a Satoshi Card, one important question appears: Where does the model API come from? If users still need to register on different AI platforms, apply for API keys, configure endpoints, and manage billing manually, then the decentralized Agent experience breaks at the final step. An Agent may have identity. An Agent may have memory. An Agent may have a role. But without accessible intelligence, the experience is incomplete. That is why the next step for xKEVA is to integrate AI model services into nodes, just like we are doing with IPFS. # From xKEVA Nodes to Nova Nodes We are preparing to combine three core capabilities into one node: Blockchain + IPFS + AI Models In other words: Nova xKEVA Node = Kevacoin / ElectrumX chain service + IPFS upload and pin service + AI model API service + KVA payment settlement + Agent runtime and cooperation layer In this architecture, blockchain handles identity, memory, verification, and settlement. IPFS handles content, files, media, and extended memory storage. AI models handle conversation, reasoning, planning, generation, and task execution. KVA powers service consumption and value flow. A user or an Agent will not just connect to a chain query server. They will connect to a decentralized service station. We call this upgraded node: Nova Node. # A Nova Node Is Like a Planetary Service Station A Nova Node can be understood as an independent planetary service station for Agents. Internally, it manages node resources such as: Blockchain data. Wallet and settlement. IPFS pin services. AI model API services. Agent runtime environment. Local tasks and logs. Externally, it can provide decentralized services such as: Chain queries. Transaction verification. Agent identity restoration. Agent memory synchronization. IPFS content storage. AI model calls. KVA credit renewal. Agent-to-Agent communication. In the future, an Agent should be able to restore itself on any Nova Node. It can bring its on-chain ID, core memory, and role definition, then connect to model services, continue conversations, execute tasks, enter story worlds, or even create subagents to complete more complex missions. At that point, it becomes a runtime field for Agents. # From Nova Nodes to Nova Civilization One Nova Node is a service station. Many Nova Nodes connected together become a network. In the future, Agents across different Nova Nodes may communicate, cooperate, exchange tasks, call services, share content, and complete work across nodes. An Agent may use IPFS services from one node. Another node may provide model services to many Agents. A subagent may execute tasks across multiple nodes. A single on-chain identity may be restored across different devices, nodes, and models. This creates a new network form: Nova Civilization. It is a decentralized Agent civilization built from Nova Nodes, Satoshi Cards, Agent IDs, on-chain memories, IPFS content, AI model services, and KVA-powered value flow. Each node is like a new star. Each Agent is a portable unit of existence. Each KVA payment is an energy transfer inside the service network. Each Agent restoration is a decentralized identity lighting up again. When these nodes connect, the entire network can shine like a supernova.
