The world has seen the rise of new technology that is changing how we do business and live our lives. From smartphones to smart homes and everything in between, technology moves at a lightning-fast pace. One such innovation is blockchain technology. The blockchain is a digital ledger that records transactions made in cryptocurrency, but its potential uses go far beyond digital currencies. It’s still relatively new, but many expect it will revolutionize how we do business and more.
The blockchain is a digital ledger in which transactions made in cryptocurrency are recorded chronologically and publicly.
The blockchain is a digital ledger in which transactions made in cryptocurrency are recorded chronologically and publicly. It’s also known as a distributed ledger, because it’s shared across a vast network of computers, rather than stored on one central server. Each time someone buys or sells something using Bitcoin (or any other cryptocurrency), that transaction gets logged onto the blockchain. The result is an immutable record of all activity on the network–an open book that anyone can read but no one can change once written down.
To put it another way: think of your bank account as being like an old-fashioned checkbook register with numbered pages where you keep track of every transaction you make by writing them down on blank lines; when the page fills up with entries that no longer fit on it anymore, you tear off the top sheet and start again at number 1–but instead of using paper records in which information must be added manually by hand each time something changes hands (and therefore relying solely upon human error for accuracy), imagine if instead every single piece of data from all over the world were kept digitally and updated instantly whenever necessary?
A blockchain is analogous to a shared Google Document.
A blockchain is analogous to a shared Google Document. It’s an ever-growing list of records, called blocks, which are linked together and secured using cryptography. Each block contains a link to the previous block, timestamp information and data (generally represented as “transactions”). This creates an unbroken chain back to the very first block in the chain–hence the term “blockchain.”
The key difference between traditional databases and blockchain databases is that while traditional databases reside on one computer or server (i.e., they’re centralized), with blockchain technology there’s no central server at all; instead there are thousands upon thousands of copies distributed across the internet.*

Cryptography is a method of storing and transmitting data in a form that is hard to decrypt. It can also be used to verify the origin of data, which is why it’s so important for blockchain technology. The blockchain uses cryptography to link together blocks of code; this makes it difficult for anyone else except those who have access to your private key (and even then)
Blockchain technology was invented by Satoshi Nakamoto in 2008 as the public ledger for digital currency bitcoin.
The blockchain technology was invented by Satoshi Nakamoto in 2008 as the public ledger for digital currency bitcoin. It’s also known as a distributed database, as it allows information to be stored across multiple computers. This makes it much harder to tamper with or hack than traditional systems, where information is stored on one central server.
It’s not clear who Satoshi Nakamoto is–or was. The name was used by the creator(s) of bitcoin, who wrote thousands of posts about the cryptocurrency before disappearing from the internet in 2011 without revealing their identity or location. Afterward, other developers have taken up his mantle and continued working on bitcoin’s codebase (the underlying software).
Cryptocurrency is a digital currency that uses cryptography for security and verification purposes.
Cryptocurrency is a digital currency that uses cryptography for security and verification purposes. Cryptocurrency is not controlled by a single entity, but rather it is decentralized. Cryptocurrency can be used to buy goods and services, or exchanged for other currencies such as US dollars (USD).
Cryptography is the practice of encrypting messages so that only the intended recipient can read them; this process relies on complex mathematical problems that take time to solve–encryption schemes will vary in terms of how long they take to break down into usable data again based on their complexity level.
Decentralization will revolutionize a lot of things, including the way we do business, government and more.
Decentralization is a way to distribute power and authority. It’s a way to make things more efficient, secure and transparent.
Decentralization is so much more than just a buzzword; it’s a movement that will revolutionize how we do business, government and more.
In the future, we will see much more use of blockchain technology. It is a revolutionary way to store data that can be used in many different industries. The most obvious use case for blockchains is cryptocurrency like Bitcoin or Ethereum, but there are also other applications such as voting systems or supply chain management.
