Blockchain and Web3
Trust comes from the protocol, not the middleman
Blockchain technology provides a tamper-resistant, 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 makes unauthorised changes detectable and harder under the chosen consensus and governance model. It does not prevent them absolutely, since chain reorganisations, compromised keys, smart-contract bugs and administrative power in permissioned chains remain possible weak points.
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: Tamper-resistant, low-gap evidence of the origin and condition of products across the stages of the supply chain; the chain records attestations tamper-evidently, but the truth of the physical-world inputs still depends on scanning, custody and oracle controls.
- 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 reduces the coordination overhead between different parties, as everyone accesses the same, tamper-resistant 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) avoid the mining energy of Proof of Work; their actual energy use depends on consensus, node count, throughput and infrastructure, and cannot be equated wholesale with a single conventional web application.
