AI Prompt Engineering 2024: Techniques That Work

Prompt engineering structures LLM input at inference time — no weight updates required. This article covers the techniques that proved reliable in 2024: zero-shot task framing (Brown et al., 2020), chain-of-thought reasoning (Wei et al., 2022), self-consistency sampling (Wang et al., 2022), ReAct agent loops (Yao et al., 2022), indirect prompt injection risk (Greshake et al., 2023), and applied RAG patterns from financial services.

Generative AI in 2023: How It Works, Where It Lands

Generative AI crossed from research curiosity to production deployment in 2023. GPT-4, Claude 2, Llama 2, and Mistral demonstrated that large language models could handle legal document review, code generation, and customer dialogue at human-comparable quality — raising immediate governance questions about hallucination, data leakage, and regulatory compliance in financial services.

The making of the Express Transaction Credits Platform

A hands-on account of building the EXTC platform on Ethereum ERC-223 in early 2018: how the token contract was structured, what the multi-signature and time-lock primitives were designed to do, and what the experiment revealed about blockchain's practical limits for payment networks.

Unveiling a new Cryptocurrency and Faster Payment Solution

The Express Transaction Credits (EXTC) platform was an early-2018 experiment in programmable payments on Ethereum, using ERC-223 smart contracts to enable instant cross-border transfers and atomic payment flows — ideas that decentralised finance later scaled.

Understanding the Technology behind Blockchain

Blockchain is an append-only ledger secured by cryptographic hash chains and distributed consensus — a design that makes tampering computationally expensive and auditable by anyone. Ethereum extended this foundation with a programmable execution layer, turning a simple payments record into a platform for smart contracts, tokens, and decentralised finance.
