CryptoNote protocol-based e-cash system —MKEcoin (Monke Coin)
The successful application of Bitcoin as the first point-to-point transmission electronic cash model. Compared with legal currency, Bitcoin does not have a centralized issuer, but is generated by the calculation of network nodes. Anyone can participate in the manufacture of Bitcoin, circulate around the world, buy and sell on any computer connected to the Internet.
The original Bitcoin was just a few thousand lines of code, and the value was not reflected, but because of its decentralization and encryption, it was essentially an anti-inflation currency, because of its decentralized “mining” incentive mechanism. Coupled with the inherent scarcity of Bitcoin and the 21 million Bitcoin output cap, many people and even institutions regard Bitcoin as hard currency. This means that internal monetary policy is driving the purchasing power of Bitcoin. On the other hand, Bitcoin’s biggest innovation is the application of blockchain technology, each block representing transactions in a Bitcoin network. The more blocks, the longer the trading time, thus forming a “chain “, although this” chain “has no actual commercial value, but because of the decentralization of value demand continues to increase, prices also rise with the water.
As technology advances, it’s not a problem to replicate any more Bitcoin networks, but so far no blockchain network has been able to match Bitcoin. A lot of facts have proved that blockchain networks in the digital economy, if separated from commercial applications, mean that bubbles are made purely. The strong have been established since ancient times, and only “killer apps” can shake Bitcoin’s position, although there are inevitable defects, but it will not affect its value at all, unless emerging technologies break the balance and make this decentralized environment no longer exist, But this is not impossible, plus Bitcoin in the transaction confirmation time is slow, poor value support and other hard injuries. There is no credit endorsement from any government or institution behind Bitcoin, which is prone to deflation with obvious market ups and downs. In terms of vision, it is already a bit contrary to the initial anti-inflationary heart, and it is difficult to realize commercial applications. The contribution to the development of digital economy is insignificant. Therefore, we think that in the development mechanism of digital economy, it is more effective to introduce a new application than to permanently repair the original application without a block chain network with commercial applications. MKEcoin (Monke Coin) is also born on this demand.
MKEcoin is a subchain technique based on Monero CryptoNote protocols. MKEcoin effectively inherits the privacy, decentralization and extensibility of the main chain Monero, and its powerful expansibility alleviates the storage pressure of the main chain. With its custom DPOS consensus mechanism, it meets the needs of more DAPP and other commercial applications in the future.
MKEcoin based on CryptoNote protocols, significant algorithm differences blur blockchain transactions, focusing on private and censored boycott transactions, transactions are confidential and untraceable to ensure user information security for each transaction. CryptoNote is an application layer protocol that supports a variety of decentralized, privacy-oriented digital currencies. Its goal is to become the evolution of ideas behind Bitcoin.
Different from Bitcoin, CryptoNote transactions can not display the way money is sent or received through block links. The approximate number of transactions can be known, but the sender, receiver and actual number can not be known. the only information available is that the actual quantity is lower than the quantity shown. the only person accessing the entire dataset about a transaction is the sender or receiver of the transaction and the person with one or two secret keys; another significant difference is the CryptoNote hash-based workload proof algorithm. Bitcoin is used SHA256, It is CPU binding function. this means that participants (miners) are only limited by their computational speed, and it is relatively cheap to create dedicated integrated circuit (ASIC) devices, which will have a hash per unit of currency over the normal computer. CryptoNote use memory binding functions CryptoNight, can not easily pipeline production.
MKEcoin sub-chain technology realizes the scalability of block chain system and provides a feasible solution to block chain fragmentation. MKEcoin subchain derived from the main chain platform with independent functions of the block chain. These subchains can not exist alone and must be run through the infrastructure provided by the main chain, so the subchain inherits all the attributes of the main chain.
A significant feature of MKEcoin subchains is the ability to define their own consensus approach and execution modules. Far from being limited to the different consensus modes of the main chain, the consensus mode of the sub-chain can be POW ,PBFT ,POS ,DPOS, even the consensus mode that different industries can define themselves. Of course, the user must define the consensus engine separately to implement the task under the custom consensus mechanism. There are several advantages to this :1. The function of the subchain is greatly enriched in a flexible way. The function of the sub-chain is not only limited to the scope of intelligent contract processing, but also increases the practicability. 2. can make full use of MKEcoin main chain to quickly deploy subchains with new functions without the need to maintain the nodes needed for a separate block chain and the cost of attracting new users to participate. 3. the difficulty of deploying subchains is greatly reduced, we only need to write subchain consensus and execution module.
MKEcoin unique custom consensus mechanism and execution module, according to the needs of the application scene, quickly form a consensus module to achieve its commercial value, and MKEcoin the block speed is independent, not limited by the public chain, Can customize block speed according to application requirements to meet transaction fluency and balance.
MKEcoin sub-chain technology can not only be used as a DAPP support platform to build complex application scenarios, but also can be deployed as a common service platform to provide specific services for other sub-chains or DAPP. MKEcoin realizes the cross-chain transaction with other block chains, and more broadly, realizes the communication between block chains and other networks, forming the interconnection of all things.

Cryptorefills launches x402 payments for AI agents, publishes agentic commerce reference
USDC payments on Base for AI agents at checkout, alongside open-source documentation of how merchants run agent-driven commerce.
Amsterdam, May 11th 2026, ZEX PR WIRE, 15:00 CEST. Cryptorefills has enabled x402 payments at checkout, allowing AI agents to pay for gift cards, mobile top-ups and eSIMs using USDC on the Base network. The protocol, developed by Coinbase and Cloudflare, lets autonomous software settle stablecoin transactions programmatically. Cryptorefills has also published an open-source operations reference for the merchant operations layer of agentic commerce.
x402 lets a software agent receive an HTTP 402 Payment Required response from a merchant, settle the requested amount in stablecoin, and complete the transaction in a single automated exchange. For Cryptorefills, checkout becomes a programmable endpoint that agents can call directly.
The x402 launch adds a second agent-payment rail to the platform. Cryptorefills released its Model Context Protocol server in October 2025, allowing agents to discover products, build orders, and complete purchases through MCP. x402 addresses a different pattern: the agent calls a Cryptorefills endpoint, receives payment terms, settles in USDC, and completes the request in one round trip. The two rails serve different agent contexts and run in parallel.
“We shipped x402 and open-sourced our merchant operations work in the same week on purpose. One is a payment rail, while the other is what a merchant needs around it to accept agent traffic. Agentic commerce is happening, and very little about the second part has been written down,” said Massimiliano Silenzi, CEO of Cryptorefills. “We’ve been running stablecoin checkout since 2018, and a lot of what we learned there carries over. We chose to publish what we’ve learned and continue building the rest openly.”
The reference repository, available at github.com/Cryptorefills/agentic-commerce, covers the operations surface that surrounds the protocol stack. Topics include catalogue discovery for agent buyers, settlement reconciliation across chains, quote-and-pricing handling, and delivery confirmations. Documentation is released under CC0; example code is Apache 2.0.
“In the repository we just open-sourced there are nine playbooks, the TypeScript schemas behind them, and five runnable examples. Two of them connect to our live MCP and x402 endpoints, so a developer can clone the repository and watch the agent-merchant exchange execute against production,” said Simonluca Landi, CTO of Cryptorefills.
Cryptorefills serves AI agents through three of the field’s emerging standards: MCP for context, Agent Skills for capability publishing, and x402 for stablecoin settlement.

Collaboration to focus on cost-effective capture and mineralization of biogenic CO₂ in Europe
Korea South, 11th May 2026, – SEOUL, South Korea & KORTRIJK, Belgium – South Korea’s ICEnergy and Belgium-based Emicap have partnered to deploy cryogenic carbon capture systems targeting biogenic CO₂ in Europe. The partnership combines ICEnergy’s proprietary capture technology with Emicap’s cryogenic R&D and market access, supported by Emicap’s sister company, LM Engineering, which provides industrial engineering and execution capabilities.
Dr. Sungho Park(icenergy0805@gmail.com), CEO of ICEnergy, stated that he hopes this partnership will enable ICEnergy and Emicap to take a further step toward realizing carbon neutrality in the European market. The collaboration comes at a pivotal moment following the successful demonstration of ICEnergy’s technology. Amid a rapidly expanding European market for biogenic CO₂ solutions, early deployment is critical to secure access to high-quality feedstocks and permanent storage pathways.
ICEnergy recently demonstrated a 10 ton/day cryogenic carbon capture system for both onshore and marine applications. The system converts flue gas CO2 directly into dry ice, avoiding the need for conventional separation and liquefaction steps. A key feature of the electrically driven process is the internal recovery and reuse of cold energy. By recycling this energy, external demand is reduced and consumption is focused on CO₂ conversion, resulting in approximately 30% lower energy use compared to conventional systems, supporting a low lifecycle carbon footprint.
Emicap integrates cryogenic CO2 capture with downstream applications by coupling emission sources from Waste-to-Energy and biomass plants to the carbonation of alkaline industrial residues such as steel slags and fly ash. To ensure seamless site-specific deployment, Emicap applies its cryogenic R&D expertise to tailor ICEnergy’s capture systems for these European industrial plants. This integration enables the permanent storage of CO2 while upgrading captured emissions and industrial residues into supplementary cementitious materials for use in low-carbon construction. By operating across the full value chain, Emicap helps offset capture costs, reducing reliance on institutional subsidies.
The partners are targeting removal of up to 200 kilotons of CO₂ annually by 2035, positioning the collaboration to contribute to industrial-scale, net-negative emissions.
