Journal of Computer Science, Published online: 25 May 2026; doi:10.3844/jcssp.2026.1703.1720 All facets of daily life are now impacted by transaction data. The complex and heterogeneous network created by millions of users, devices, online services, and applications makes digital identity man...

Multisig wallets are widely considered one of the most secure methods for managing cryptocurrency assets, especially for teams, DAOs, organizations, and high-net-worth individuals. Unlike traditional single-signature wallets, multisig requires multiple private keys to approve a transaction, significantly reducing the risk of a single point of failure. However, despite their strong theoretical des…

If you told me a week ago that I could create a custom currency, add brand metadata, enforce automatic transaction fees, and create "soulbound" non-transferable credentials—all without writing a single line of backend API code—I would have been skeptical. Coming from a Web2 background, my brain is wired to think in APIs, Databases, and Middleware. But over the last few days, I’ve been building on…

Operational Technology (OT) is experiencing one of the most remarkable shifts in its history as increased OT and Information Technology (IT) systems converge to form unified, intelligent systems. The aim of this review article is to look at the most important technology trends that are currently changing the OT landscape and consider the impact of these on architecture, operation, and security fo…

6G paradigm enables massive network slicing for pervasive digitization across vertical industries, demanding scalable,sustainable, AI-driven zero-touch automation, particularly under non-IID conditions in live networks. This work introducesa cloud-native service-level agreement (SLA)-driven stochastic policy to guarantee a scalable and fast operation of constrainedfederated learning (FL)-based an…

With the increasing deployment of Reinforcement Learning (RL) for network optimization at the edge of wirelessnetworks, the RL workload emerges as a significant challenge. While the placement of general Machine Learning workloadsacross the cloud–edge continuum has been widely studied, existing solutions typically exclude RL techniques due to theirdistinct structure and operational requirements. I…

Sixth-generation (6G) wireless networks are expected to meet all the demands of the next decade, a feasibility that is onlypossible with advances in network design and management. This paper first proposes a unified resource management framework for a 6G-based network architecture that includes an Open Radio Access Network (O-RAN) deployment and then defines a hierarchical network energy control …

I spent the past week building tokens on Solana. Not wrapping existing ones, not swapping — actually creating token mints from scratch, attaching economic rules to them at the protocol level, and watching a blockchain reject a transaction I told it to make. This post walks through what I built, what surprised me, and why the Token Extensions Program changes how I think about on-chain rules. Where…

A few months ago I launched a paid Telegram bot. No Stripe, no checkout page, no app-store account. The whole subscription runs on Telegram Stars — Telegram's own in-app virtual currency. People had questions. The most useful answer was the math, which nobody publishes openly. So here it is. The setup PolySignal is a Telegram bot that alerts users when top wallets on Polymarket make a trade. It h…

I spent the last five days building tokens on Solana — and it completely changed how I think about what a "token" actually is. Coming from Web2 and EVM development, I assumed a token was a number in a database with some transfer logic wrapped around it. On Solana, it's much closer to a configurable protocol object. Here's everything I learned across Days 29–33 of my #100DaysOfSolana challenge. Th…

We analyze the linearized dynamics of the validated late-time coherence-field kernel of Radial Coherential Dynamics (RCD), the bistable Allen–Cahn / Wright–Fisher reaction–diffusion equation whose coarsening behavior in expanding Friedmann–Robertson–Walker (FRW) backgrounds was established in prior work [1]. Computing the principal symbol of the operator governing small perturbations δC about a h…

We prove that E7 is the unique simple Lie algebra g for which the quantity dim(g) + max_mark(Ĝ) is simultaneously prime, congruent to 1 (mod 4), and a Gaussian prime norm on the cascade tower of z = 2+i. The proof is by exhaustive enumeration over all simple Lie algebras—the four infinite classical families (An, Bn, Cn, Dn) and the five exceptional algebras (G2, F4, E6, E7, E8)—using a three-laye…

We study the expression complexity of the Riemann explicit formula from the perspective of grammar-based symbolic regression. Starting from the EML operator eml(a,b) = exp(a) − log(b), we show that this operator fails to produce oscillatory terms and therefore cannot encode the explicit-formula structure. We then derive a replacement operator eml_zeta(g, t) = (cos(γt) + 2γ sin(γt)) / (¼ + γ²) dir…

This technical note is Part I-2 of the AIKernel / AIOS Phase-1 specification series. It defines the VFS Architecture and Semantic Storage Model as the storage boundary governance layer for deterministic AI systems. The paper introduces capability-based VFS sessions, non-routable transition semantics, bounded storage topology, and deterministic read-only projection for replay. It formalizes storag…
