Agentic Settlement Protocol: An Application Profile for Refundable, Delayed-Fulfilment Agent Commerce on Stablecoin Rails

Autonomous agents can already pay per request: HTTP-native protocols such as x402 let an agent sign a stablecoin authorization and receive a resource in the same round trip. That model is atomic and final, which suits metered access and fails commerce: a purchase made on a person's behalf -- a service appointment, a physical order, a flight -- is large, frequently cancelled, and should not become the seller's money until delivery. We present the Agentic Settlement Protocol (ASP), an application profile over on-chain authorize-and-capture escrow (as standardised by the Commerce Payments Protocol) for businesses whose fulfilment is confirmed off-chain by their own order, scheduling, invoicing or booking system, abstracted as a fulfilment engine. ASP contributes: a three-deadline hold model separating the issuance deadline, escrow expiry and the engine's inventory expiry by an explicit submission-inclusion-finality margin, under which no inventory is issued against reclaimable funds; a fulfilment-verification ladder stating who is trusted to trigger capture, what their attestation proves, and under what challenge window; engine-authoritative partial refunds with a refund-liquidity order and per-seller exposure controls, including atomic exposure reservation, that bound the operator's credit risk; distributor revenue share that is provably unprofitable to self-deal; a single-currency-per-charge invariant; and a normative interface specification (x402 scheme, vault ABI, operator and connector APIs, conformance levels) intended to let independent implementations interoperate. The design originated in a review of travel-agency participation in agentic settlement and is instantiated on the XDC Network. This is a design paper; a fault-injection evaluation plan is specified and measurement is left to follow-up work.

XDC Gasless Subnet: Gasless Subnet Staking dApp for XDC Network

With a delegated proof-of-stake (XDPoS) consensus mechanism, the XDC Network is an enterprise-focused blockchain platform that combines the strength of public and private blockchains to provide quick transaction times, low energy consumption, and economical gas fees. XDC is designed for interoperability and supports decentralized apps (dApps) and integrates smoothly with financial systems. It is perfect for trade financing and tokenisation of physical assets because of its emphasis on security and scalability. However, there are a few critical issues that hamper wider acceptance and usability for certain high-frequency applications. This whitepaper introduces a novel and enthralling dApp for establishing a gasless subnet in which mainnet XDC can be staked to spin off a subnet that functions similarly to a non-crypto network, accepting currency fees on the XDC network. This would allow users to stake their tokens without incurring gas fees making the staking process more efficient, cost-effective, and simultaneously enhancing scalability. Performance evaluation of the dApp shows promising results in terms of throughput, latency, scalability, security, and cost efficiency. The use cases and applications of this approach along with challenges and ensuing solutions are included.

XDC Network Assessment: Decentralization, Scalability and Security

XinFin, in 2019, unveiled the XDC network, an enterprise-ready hybrid blockchain platform that is open-source and specializes in tokenization for real-world decentralized finance. Overseeing the XDC network is currently the XDC Foundation, a non-profit organization established to encourage the growth, enhancement, and adoption of the XDC Network through community-driven projects such as GitHub. This whitepaper discusses the real-time assessment of the XDC network's decentralization, scalability, and security aspects as well as the Nakamoto coefficient estimation that follows, which is a measure of a decentralized system's decentralization nature that quantifies the minimal number of nodes or entities needed to compromise the system. A high coefficient denotes greater decentralization, while a low number denotes increased disruption risk. The XDC network's real-time computation of the high Nakamoto coefficient demonstrates its highly decentralized character. The article also addresses the diversity of consensus and execution clients, the host distribution, the geo-distribution, and some of the outstanding issues and business considerations.

Assessing the XDC Network: A Comprehensive Evaluation of its qualitative and technical aspects

This research provides a thorough assessment of the XDC Network, a delegated proof of stake (XDPoS) consensus-based blockchain technology, across its technical, security, and business dimensions. The study evaluates the network's decentralization, scalability, and security features, including its Nakamoto coefficient, validator participation, and client distribution. Additionally, it examines the developer ecosystem, including GitHub metrics, and business aspects such as transaction costs and predictability. The findings of this research will provide valuable insights into the strengths and weaknesses of the XDC Network, informing stakeholders and decision-makers about its suitability for various use cases, particularly in trade finance, asset tokenization, and enterprise blockchain solutions.
