“Die wahre Innovation liegt nicht im Tool selbst, sondern darin, dass jemand erkannt hat: Der Netzwerkeffekt von PEPPOL bricht zusammen, wenn die "last mile" - das Lesen der Rechnung - ein proprietärer Flaschenhals bleibt.

Während alle über KI-Revolution diskutieren, löst hier jemand mit simplem JavaScript ein 10-Milliarden-Euro-Problem: Wie macht man europäische Digitalisierung tatsächlich nutzbar für den Mittelstand?

Die Ironie? Brüssel investiert Hunderte Millionen in E-Invoicing-Standards, aber vergisst, dass Standards nur funktionieren, wenn sie auch lesbar sind - chapeau für diesen demokratisierenden Ansatz.”

The Big Extraction: A Forensic Leaderboard for Uniswap V3 MEV Activity

Decentralised exchanges (DEX) do not have a compliance desk, and they do not file suspicious activity reports. What they do have is a public ledger, and that ledger records every trade in enough detail to reconstruct who extracted value from whom, and when. The MEV leaderboard engine presented here is an attempt to impose some analytical structure on that record for the ETH/USDC pool on Uniswap V3.

How to Compare two Peppol Invoices for Forensic Audit?

Electronic invoicing has significantly improved automation and interoperability across Europe. However, as Peppol adoption grows, so does the complexity of ensuring invoice integrity across systems, intermediaries, and ERP exports. Even small, unintended changes in structured XML data can lead to accounting discrepancies, compliance risks, or audit findings.

How to view and inspect PDF e-Invoices?

From a cybersecurity and information protection perspective, the rise of hybrid PDF e-invoices (Factur-X and ZUGFeRD) introduces a specific question: how can organizations inspect, validate, and audit electronic invoices without exposing sensitive financial data to external systems, ERP platforms, or cloud services?

How do I view a SAF-T file online, without ERP?

The Standard Audit File for Tax (SAF-T) is the international benchmark for digital tax reporting. While it was designed to give Tax Authorities a transparent view of a company’s financial health, the heavy XML format is notoriously difficult for accountants to read.

The Difference Between camt.052, camt.053 and camt.054

Corporate treasury teams often encounter questions about bank statements and reporting formats, especially as more institutions migrate to the ISO 20022 standard. While formats such as BAI2 or MT940 are still familiar to many practitioners, the CAMT family of messages, camt.052, camt.053 and camt.054, now represents the modern, structured way for banks to deliver account information to their customer.

Uniswap MEV Leaderboard

On-Chain Forensics

We developed an open monitoring system for the Uniswap V3 USDC/ETH pool on Ethereum mainnet — one of the most actively traded decentralised venues in DeFi. Every swap, every wallet, every gas fee is recorded permanently on the public blockchain. We collect that data, process it daily, and rank wallets by how much value they extracted from the pool.

The leaderboard tracks net USDC extracted after gas, win rate, profit factor, and CEX-informed trade percentage — giving a clear picture of who has systematic edge in this market and how they operate.

MEV Leaderboard

Maximal Extractable Value (MEV) refers to the profit that automated traders capture by exploiting the publicly visible nature of Ethereum transactions. Arbitrageurs, sandwich bots, and CEX-DEX traders continuously compete to extract value from liquidity pools — at the expense of ordinary users and liquidity providers on the other side.

MEV is a well-documented and neutral feature of permissionless blockchains. Transparency about who extracts value, how much, and how consistently is essential for informed participation in decentralised markets. All data shown in MEV Leaderboard is derived from public on-chain records.

Open-Source Wallet Analytics

Our monitoring system includes the on-chain data collector, leaderboard engine, and CEX signal pipeline. It is being prepared for open source release in 2026. Built in Python, it runs on modest hardware and is designed to be reproducible by anyone with access to an Ethereum archive node and basic infrastructure.

Planned additions include support for additional Uniswap V3 pools, cross-pool wallet tracking, sandwich attack detection, and LP loss attribution. Contributions and feedback are welcome.
