This document covers information about Blockchain technology used by wunderbon



wunderbon uses blockchain technology to secure the smart receipts and to guarantee their authenticity.

No other technology is more suitable for us as an intermediary to fulfil our task of guaranteeing fair data exchange between Merchants, Suppliers and Consumers.

wunderbon does not try to reinvent the wheel. We do rely safely on an existing, modern blockchain providing support for smart contracts.

By design, a blockchain is resistant to modification of the data. It is "an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way". For use as a distributed ledger, a blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for inter-node communication and validating new blocks. Once recorded, the data in any given block cannot be altered retroactively without alteration of all subsequent blocks, which requires consensus of the network majority.

Although blockchain records are not unalterable, blockchains may be considered secure by design and exemplify a distributed computing system with high Byzantine fault tolerance. Decentralized consensus has therefore been claimed with a blockchain.



wunderbon guarantees the authenticity of the delivered receipts and their content. Due to our block chain-based network and the security procedures used we are always able to check the authenticity of each document in real-time. Thus we are able to offer secure receipt-based cashback or loyalty campaigns.


wunderbon guarantees the status of a document in real-time. Through the wunderbon network the status of every single issued receipt can be validated at any time. Be it for complaints/exchanges or the redemption of cashback points, wunderbon always provides an up-to-date answer.
