Abstract

Blockchain is a technological concept which evolves from the first cryptocurrency, Bitcoin, and disrupts constantly enlarging areas of economy. The concept of blockchain is developing, and while the future of Bitcoin remains unclear (as it is for the most elements of the economy) it is evident that the blockchain holds enormous potential for large-scale improvements. However, being a technology that could decrease significance many of today’s large global corporations, institutions and power structures which have keen interest in preserving established hierarchies, its potential could well remain unexploited. This paper aims to introduce and present the concept of blockchain and its current applications in logistics and supply networks. Blockchain technology promises overpowering trust issues and allowing trustless, secure and authenticated system of logistics and supply chain information exchange in supply networks. The new implementations within supply chain are shifting from blockchain to a wider notion of distributed ledger technologies. Paper presents description and rationale behind current and possible future applications of blockchain in logistics and supply chain.

Vorheriges Kapitel E-Supply Network Management—Unused Potential?

Nächstes Kapitel New Technological Solutions in Logistics on the Example of Logistics Operators in Poland and Ukraine

Data from https://coinmarketcap.com (accessed 5. 1. 2018). Tokens are digital assets such as vouchers, debt instruments (IOUs), or real-world objects. They are mostly based on the Ethereum blockchain.

Focal company (or company in focus) is supply network member from whose perspective is supply network (or supply chain) mapped.

Intermediaries are not viewed “intruders” per se, but as entities which insert additional layers of costs into the price structure.

Private keys are an unintelligible string of numbers and letters, thus not revealing the identity of the signatory to other parties in the network, which is another feature of the crypto-network.

This is a simplification to an extent. The description of actual content of a bitcoin block can be found at [4].

I.e. Merkle tree, a data structure used for efficiently summarizing and verifying the integrity of large sets of data [4].

The question is: searching for a nonce is hard work and costly, but is it meaningful? Pushing the computer to the maximum speed to find an absolutely random number, of what use is that? The use is in providing an existential meaning to money in a digital world. Something cannot come from nothing; digital money cannot be borne out of thin air, from the cloud of zeros and ones. It is “minted” in a computational contest among the competitors which race to verify the contents of the blocks in the chain and to arrange the blocks in a meaningful manner.

In bitcoin that is approx. 150 GB of data, in January 2018.

A programming language is said to be Turing-complete if it can be used to simulate any Turing machine. Turing machine is able to answer any computable problem given enough time and space. The early computers were dissimilar machines because different machines were built for different programs. Mathematician Alan Turing created “Universal Turing Machine” that could take any program and run it. Our personal, home computers are universal machines, and they can be used for any program and solve every problem, given enough time and space (memory).

A case which affirms this position is the introduction of federated blockchain-based technology which replaces the previous clearing system on the Australian Stock Exchange, which is dubbed as “distributed ledger technology”, but not as a blockchain.

They cannot easily change previous blocks, especially those deeper in the chain; every intervention would be seen because all the subsequent blocks would not have a valid reference.

Google Sheets and Microsoft Excel with Onedrive offer these for free.

Rootstock is a platform for smart contracts in parallel blockchain with Bitcoin (a Bitcoin sidechain), and in this was an alternative to Ethereum.

This could be used for arbitrage between exchanges which could stabilize the price of Bitcoin.

Industry is stacked with buzzwords which do have both meaning and purpose, but often get over-used and abused to the point where they become hollow phrases. Examples are artificial intelligence, big data, cloud-based, disruptive, Internet 3.0 (or higher), machine learning, internet-of-things, open-source, etc. Blockchain, unfortunately, seems to be on the same path.
