One of the most important lessons I’ve learned while investing in cryptocurrency assets is the importance of understanding how this technology works and how it can be leveraged. It makes little sense to simply follow the herd when there are great online tools and learning courses available; some key questions I’ll try to address are how blockchain can be used in real life, how can projects successfully mature this technology, and why blockchain matters as a new system for trust.
But first things first: how can we define what is and what isn’t a blockchain?
I’ll borrow some knowledge from the awesome Bitcoin Developer Jimmy Song, who in my view explains these differences brilliantly.
“The main thing distinguishing a blockchain from a normal database is that there are specific rules about how to put data into the database. That is, it cannot conflict with some other data that’s already in the database (consistent), it’s append-only (immutable), and the data itself is locked to an owner (ownable), it’s replicable and available. Finally, everyone agrees on what the states of things in the database are (canonical) without a central party (decentralized).”
Now that the cat is out of the bag, and there is a clear distinction between standard databases and blockchain ledgers, I’ll base my explanatory arguments in the Linux’ foundation course Blockchain: Understanding Its Uses and Implications. For a more in-depth analysis, please complete the curriculum, as it’s free of charge and really helps developing solid knowledge on public blockchains and private ledgers.

Do not invest what you cannot afford to lose and always read as much as possible about a project before investing. Never forget: with great power, comes great responsibility.

The very first question we ought to ask ourselves is: how can this technology help humanity? For any new technology to have a long-term impact in the global economy, it must bring some sort of advantage or value over traditional tech.
We start with Bitcoin, by far the most successful implementation on top of the blockchain, which will always be required to make sure it remains decentralized. However, if we consider a mixture of public and private ledgers accessing information via interoperable systems, we could imagine different levels of trust being created between participating agents. That is, we could have a public blockchain serving as an immutable record for some type of businesses transactions, such as tax payments, loans, and settlements, while a private ledger keeps some of the data private, within the organization’s nodes, only accessible by authorized agents (like company employees). Examples of such data could be:
The core reason why blockchain matters, in the end, is to increase trust between parties through decentralized systems. Blockchain can help humanity by creating more transparent ecosystems, easily auditable by anyone, where the standard rules apply to everyone equally.
The blockchain is built of several different types of components, each with a specific role to play within the ledger’s operation. Let’s look at each individually:
Data and governance structures are most commonly distributed and decentralized; nonetheless, it’s important to distinguish between the two major dimensions that compose blockchain data, as they are usually associated with scalability and performance.
Data Storage is represented by traditional databases for storing data off-chain. The blockchain provides distributed, immutable storage with built-in integrity checking, but, it has a maximum capacity based on the standard block size and block rate. To provide integrity verification for large amounts of data, it is common to store the data off-chain and store a hash of the data on-chain. This guarantees that the data is not being modified while protecting the blockchain from becoming bloated.
Data Processing is represented by an external system used for additional processing. Smart contracts execute on the blockchain, meaning that each member of the peer network must execute the code to remain in sync with the current state of the network. If smart contracts commonly require large amounts of processing power to complete, devices external to the network may be used to augment the processing power of the network.
To understand how data is written into the blockchain, one must be familiar with public-private key cryptography, based in Elliptic Curve math functions. This crypto-framework allows for agents to write data into a blockchain, as well as proving they’re the owners of said public data, without giving away access to the private keys.
There are different types of agents, and each has a unique function in either blockchain development, implementation, or support. As most expect blockchain technology will be integrated with business operations, a wide array of expertise is needed, to properly and successfully maintain a decentralized ledger.
The reason why blockchain can potentially become one of the key core business technologies in the next couple of years is due to the fact it’s the very first triple-entry bookkeeping system to be deployed on a global scale.
Triple-entry accounting is an enhancement to the traditional double-entry system, in which all accounting entries involving outside parties are cryptographically sealed by a third entry. Debits, credits, and an immutable link to all past debits and credits.
A seller books a debit to account for cash received, while a buyer books a credit for cash spent in the same transaction, but in separate sets of accounting records. This is where the blockchain comes in: rather than these entries occurring separately in independent sets of books, they occur in the form of a transfer between wallet addresses in the same distributed, public ledger, which creates an interlocking system of enduring accounting records. Since the entries are distributed and cryptographically sealed, falsifying them in a credible way or destroying them to conceal activity is practically impossible.
Triple-Entry Accounting Features:
While the social hype remains focused on cryptocurrency prices, the technological hype is based on the premise of decentralization, as through the deployment of both public blockchains and private ledgers, it will be possible to increase transparency and security for all users.
New types of decentralized organizations will empower members to use tokens to vote on governance, to store data, and share resources while being rewarded for participating in the network at the same time.
If you ask me, the future does look bright.
