While cryptocurrencies fluctuate in value and both
excite and concern investors, many have come to see
the blockchain as the wave of the future, a safe,
efficient, and effective way to store and process
information.
What is blockchain useful for and is it a cure or all ills or
are there (as with all technologies) advantages and
disadvantages? Wired published a useful article a
couple of years ago about what blockchain is good for
and decided that the answer for now is, not much!
What Is Blockchain?
A blockchain is a database. But, unlike a database
contained on your computer or office network, a
blockchain has its information distributed among
nodes of a broader computer network. A blockchain
has a built-in redundancy that preserves all data that
has been entered into the system.
Digital information is stored in blocks which, when
filled, are closed, and linked to the block before it in
the sequence. This creates a chain of information.
Blockchains are the basis for how cryptocurrencies
work.
The value of a blockchain is that it guarantees the
accuracy and security of the records contained within.
This, in turn, creates the trust needed for people to do
things like investing thousands or millions of dollars in
cryptocurrencies. Once data is entered into a
blockchain each block gets a time stamp and its data is
unchanged forever.
Uses of Blockchains Beyond Cryptocurrencies
The blockchain has found uses outside of the
cryptocurrency realm. Money transfers and payment
processing systems use blockchain technology. Such
systems are in current use.
And, there are many proposed uses for blockchain
technology including loyalty and reward programs in
retail, supply chain monitoring, digital IDs, data-
sharing networks, royalty and copywrite protection,
title transfers for vehicles and real estate, digital
voting, food safety, secure data backup, medical
records, tax information verification, workers’ rights
issues, inheritance and wills, tracking weapons, stock
trading, managing the internet of things, tracking
prescription drugs, secure access to belongings and
expediting energy futures and compliance.
The problem is that beyond a few uses in the money
payment realm and financial sector most proposed
uses are just that, proposed and not in use or proven.
A Blockchain Is Still a Database
Depending on the amount of data to be dealt with and
the complexity of the system a database can be easy to
build and maintain or require a high level of expertise
and maintenance. People who have bought into using
blockchain technology have been disappointed that
the proposed systems are not as functional as those
available using non-blockchain database technologies.
An example can be found in the Wired article. The
problem is that the data security provided by a
blockchain comes at a cost. The system is slower than
one contained within a single computer program
located on a single office network. And, when you
want to do complicated things with your blockchain
database it can require complicated programming.
The Wired article shows how a city clerk in a town in
Vermont tried to use blockchain to handle land
records. The system took a long time to start up and
when in place was slow and lacked features available
on commercially available and cheaper programs.
The clerk ended up choosing a local company with a
program with better functionality for cheaper. The
final comment from the clerk was that she did not see
any positive ways that blockchain would help the
citizens of her community.
When to Use Blockchain
The key feature of blockchain technology is that data
does not get erased from the system. This provides a
comfortable level of security and trust. The downside
is that the system is slower because of its security
features. And a database is still a database and needs
to be constructed to fit the needs of the client and
needs to be maintained.
When to use blockchain is when security outweighs the
need for speed and when you can afford to pay for a
completely new system designed for the blockchain
when there are probably several commercially
available using non-blockchain technology.
