Blockchain and Web3
Blockchain technology provides a tamper-proof, decentralised store for transactions and data. Web3 uses this foundation for a new internet paradigm in which identities and data no longer belong to centralised platform operators but to users themselves (Self-Sovereign Identity).
In a business context, the focus is on automating contracts (Smart Contracts), securing supply chains and proving data integrity without a central authority.
Anti-Patterns: The Trust Monopoly
In global value chains, parties often have to rely on expensive intermediaries or blindly trust a partner's system. This leads to high transaction costs, slow processes and a risk of data manipulation. Traditional databases can be modified by an administrator at any time — a Blockchain prevents this at the technical level.
Decentralised Automation
- Smart Contracts: Programs that execute automatically when predefined conditions are met (e.g. "payment is triggered as soon as the carrier digitally acknowledges receipt of the goods").
- Self-Sovereign Identity (SSI): Digital identities for people, organisations or machines that function without a central provider (such as Google or Microsoft) and allow full control over the data shared.
- Supply Chain Traceability: Seamless, forgery-proof proof of the origin and condition of products across all stages of the supply chain.
- Tokenisation: Digital representation of physical or intangible assets to make them easier to trade or divide.
- Public vs. Private Blockchains: Choosing the right architecture (open for maximum transparency, closed for controlled consortia).
The Focus: Efficiency Through Transparency
Blockchain eliminates the coordination overhead between different parties, as everyone accesses the same, incorruptible data source (Single Source of Truth across Organisations).
FAQ
Is Blockchain not just for cryptocurrencies?
No. The currencies are only the first application. For businesses, the underlying architecture of distributed truth is far more interesting for process automation.
Doesn't Blockchain consume an enormous amount of electricity?
That was true for early systems (Bitcoin). Modern enterprise Blockchains and new consensus mechanisms (Proof of Stake) consume no more energy than a conventional web application.
