The modern human species has been around for nearly , years. We started off as ape-like creatures, scavenging for survival, but over time have become a dominant species, able to shape the future of our little blue planet. Roughly 6, years ago, after the first civilizations, it is interesting to observe that the progress of our society has often been exponential rather than linear. New technological innovations have changed the status quo suddenly and rapidly, opening new frontiers and enabling a myriad of opportunities.

What’s a blockchain, anyway?


The blockchain is a decentralized, shared, and immutable ledger that facilitates the process of recording transactions and tracking assets in a business network. An asset can be tangible a house, a car, etc. A peer-to-peer P2P network like Blockchain is, according to the Oxford English Dictionary, a network in which each computer can act as a server for the others, allowing shared access to files and peripherals without the need for a central server. How is it decentralized you may ask?

As opposed to traditional transaction as seen below in a server-based network on Fig. A main characteristic of this decentralization is that information is continually managed and hosted by millions of computers simultaneously worldwide on a distributed database, making the data accessible to anyone on the internet.

To understand how Blockchain works, we need to first learn who participates in a blockchain network. The main participants of a blockchain network are See Fig. Most of the time these exchanges are subject to several challenges , such as the time a customer waits between transaction and settlement, fraud and cyberattacks due to simple mistakes, the possibility of exposing the participants in the network to risk if the central system i.

On the other hand, Blockchain promises to facilitate the process of business transactions through tracking and trading of valuable assets in a shared, immutable network.

Blockchain owes its name to the way it stores transaction data —in blocks that are linked together to form a chain. As the number of transactions grows, so does the blockchain.

Each block contains a hash a digital fingerprint or unique identifier , timestamped batches of recent valid transactions, and the hash of the previous block. The previous block hash links the blocks together and prevents any block from being altered or a block being inserted between two existing blocks Fig.

When a user requests a transaction cryptocurrency, contracts, records, etc in a network, said request must be validated by all the participants of the network to reach a consensus Fig. Once it has been verified, a block created with the new hash, the previous hash, and the transaction identifier Fig 3 above , is added to the existing blockchain making it permanent, visible and unalterable. If the transaction were in error, a new transaction is made to reverse the previous one, and both transactions are visible to the participants, showing transparency in the network.

All the nodes in the network check for errors in this transactions with the previous transactions correlated to the asset the user wants to transfer. When all transactions are finished, validated, and added to the blockchain, the transaction is complete.

Blockchain is a database that is simultaneously stored on a set of computers connected to each other on the Internet where each transaction is written down and safely stored; along the lines of an operating system like Microsoft Windows. On the other hand, Bitcoin is a digital currency, created and operated only on the Blockchain network; a similar example can be an application running on an operating system, such as Skype on Microsoft Windows. Next in this blog series on blockchain, we will explore the application of blockchain in Intellectual Property, explaining its role in the field of IP, determining the classes and subclasses of blockchain technology-based patents, and many other topics.

Anything of value can be tracked and traded on a blockchain network, reducing risk and cutting costs for all involved. Transactions made in bitcoin or other cryptocurrencies are recorded chronologically and publicly between two parties, being efficient and in a verifiable and permanent way.

Figure 1. Kologynski, Maria. Node: A computer connected to the network. Developer: Creator of applications and smart contracts that interact with the blockchain and are used by the users. Operator: Individuals who have define, create, manage, and monitor the blockchain network. Businesses on a blockchain network have a blockchain network operator. Determines who can participate in the blockchain, gather valid transactions from participants, etc.

Certificate authority: Manages the different types of certificates required to run a permissioned Blockchain. Traditional Data Sources: An existing data system which may provide data to influence the content and structure of smart contracts, as well as define how communications or data transfer will occur into the blockchain.

How does Blockchain work? Figure 3 — Gupta, Manav. Blockchain stores transaction records in a series of connected blocks. Blockchain for Dummies. Figure 4 — What is Blockchain Technology? Digital Image. Blockgeeks, 13 September Key characteristics What makes Blockchain different from other transaction systems are four key characteristics: Consensus: As explained before, all participants of a network must agree for a transaction to be considered valid.

Provenance: Participants know where the asset came from and how its ownership has changed over time due to the trajectory of the asset in the ledger shown to the participant Fig. Immutability: No participant can tamper with a transaction after its been recorded to the ledger. If a transaction is in error, a new transaction must be used to reverse the error, and both transactions are then visible.

Transactions are combined into single blocks and are verified every ten minutes through mining [1]. The nature of this structure permanently timestamps and stores exchanges of value, preventing anyone from altering the ledger. Finality: A shared ledger provides one place to go to determine the ownership of an asset or completion of transaction; facilitating information to users in an open network rather than using intermediaries like banks, ports, etc.

No Blockchain Experience? Real-life Examples & Blockchain for dummies 101 Course

A blockchain is a growing list of records , called blocks , that are linked together using cryptography. The timestamp proves that the transaction data existed when the block was published in order to get into its hash. As blocks each contain information about the block previous to it, they form a chain, with each additional block reinforcing the ones before it. Therefore, blockchains are resistant to modification of their data because once recorded, the data in any given block cannot be altered retroactively without altering all subsequent blocks. Blockchains are typically managed by a peer-to-peer network for use as a publicly distributed ledger , where nodes collectively adhere to a protocol to communicate and validate new blocks.
