Blockchain technology can make micropayments finally functional

Ledger Nano X - The secure hardware wallet

I recently came across Marc Andreessen’s article from 2014 on Bitcoin (BTC). In many ways, it is visionary (no surprise). I have been in the industry for four years now, with most of my focus being on the social impact of blockchain. It is astonishing to me that in 2014, before there was any institutional presence in Bitcoin — or, indeed, a popular understanding of this new technology — Andreessen was able to outline its potential economic and social impact for the future.

Nearly eight years after he inked his words, I would like to address one of the topics from his article: micropayments. I will explore how blockchain could help transform micropayments and thus enable not only the monetization of certain aspects of businesses that are in need of a solution but also could assist society’s most vulnerable.


Micropayments are not a new concept. Since the mid-1990s, micropayments have experienced various degrees of popularity. By definition, micropayments are transactions with a value smaller than a certain threshold. Importantly, below that threshold, the transaction fee incurred becomes a significant portion of the total transaction value and, consequently, not economical. Another important aspect is that due to the minuscule monetary amounts, micropayments refer only to digital transactions of non-tangible goods. Any additional cost of handling and shipping might mean a hundredfold increase of the original transaction value, making it utterly irrelevant.

Credit card companies offer merchants various types of price plans for the fees they charge. These plans usually comprise a lump sum charged per transaction and a percentage charged out of it. Not surprisingly, this information is not openly available from the card companies themselves, rather it’s published by others who compare these rates as a service for merchants. Within that context, let us examine what fee a merchant would be charged for a micropayment.

We assume the following:

● The lowest fee we uncovered was 1.29% of the transaction value, and no lump sum fee was charged.

● Since the smallest building block of (most) fiat currencies is 1/100 of the whole — i.e., $0.01 — this would be the minimum fee the credit card company charges, regardless of if it is higher than 1.29%.

Charting the proportion of the transaction fee as a function of the transaction value, we get the chart below. For example, a $0.01 transaction incurs a fee of 100%, while the fee on a $0.10 transaction is “only” 10%. Naturally, this goes to show the irrationality of carrying out micropayment transactions under these payment platforms.

Blockchain has a solution

However, there is now an alternative. Blockchain technology provides the perfect solution for micropayments, for many reasons. It provides the infrastructure for digital payments that are getting faster by the day, and importantly, the minimum payment unit of both Bitcoin and Ether (ETH) is incredibly small, as displayed in the table below:

In addition, crypto wallets are easily embedded in any digital device, whether a mobile phone, laptop or any other Internet of Things device. And while fees may vary greatly on various networks and on different occasions, fees are not an issue with many protocols and may reach as low as fractions of a cent.

Last, but certainly not least, is user privacy. Due to blockchain’s asymmetric encryption, the payer exposes only their public address when paying, which provides practically no information for someone who is looking to hack their wallets. Unfortunately, the same does not go for a credit card transaction, which requires the payer to share their full credit card number and hope the payment platform is properly secured.

Real use cases for micropayments

Now that the technological aspect is covered, only one question remains: Can I get anything for a millionth of a dollar? Well, I am not sure about a millionth, but there are many use cases for micropayments. Below are a few:

Alternative to the subscription model: There is no point in reiterating the economic reasoning behind the subscription model for consuming online content and its success in recent years, whether it is video content, music, newspapers, etc. While there are multiple advantages to this model, it is far from perfect and still has certain caveats. For instance, what if someone would like to buy just a single item rather than commit to a subscription? Let’s assume that Alice is subscribed to two online magazines when she discovers an interesting article on a third one. She will not go for a third subscription, though she is willing to pay only for that article. From the magazine’s perspective, the article is already there, so why not charge someone for it? Micropayments allow both Alice and the magazine to maximize their economic utility.

Digital copyrights, royalties and referrals: As with the previous case, there is no need to explain what copyrights, royalties or referrals are. Micropayments provide a relatively simple mechanism for the immediate settlements involved, with practically no minimum limit to the amount charged per each, unlike the complicated solutions that stand today.

IoT transactions: This use case is highly visionary, though it will probably become as mundane and trivial as a light switch, sooner rather than later. To date, IoT has barely matured into a fraction of its vast potential. One possible reason for this delay is the lack of a simple, easy-to-implement monetization model. Micropayments on the blockchain could be the answer. Think of all the data that may be collected by your car, from road conditions to traffic and more. Sharing data collected by mass users in real time could be invaluable for traffic planning and road maintenance. And as such, why not pay for it? The added value of blockchain is an improved mechanism to anonymize the data and protect user privacy — again, a winning combination. Naturally, this could work with any other IoT device, from smart meters to home appliances and more.

Social impact: This is the most straightforward use case on this list (and, obviously, my favorite). Micropayments on the blockchain can be revolutionary in two aspects. The first is that donation recipients could easily set up accounts for receiving funds, which will allow donating directly to them, cutting out all intermediaries and overhead costs. Having said that, it is critical to note that this feature is a double-edged sword that might turn out to be its major pitfall. It would be just as easy for fraudsters to set up false accounts, luring in donors. There will be a need for rating and auditing, similar to current online services that rate charities on multiple criteria (e.g., Charity Navigator, Smart Giving, Council of Nonprofits and others) in order to ensure and provide better visibility to donors. In addition, as a minimum donation amount will no longer be an issue, we may see donations of micro amounts. The World Bank categorizes a country with a gross national income per capita that is lower than $1,025 as “low income.” Put differently, this means a daily salary that is lower than $3. As of 2020 data, there are 27 low-income countries. Micropayments could provide an excellent mechanism, which must be carefully monitored for fraud, to donate funds to people in need in those countries. I think you can see how this, if managed well, could lead to more efficient giving and a more direct impact.

Over the last few years, micropayments have lost some of their initial prestige. While the concept was ahead of its time, the technology lagged behind and prevented it from materializing. Andreessen was correct and revolutionary in highlighting the ability of blockchain to transform micropayments. Here, I have barely scratched the surface in terms of the use cases and the potential.

Businesses could become more efficient and be able to monetize more of their offerings. Entire communities could be transformed or brought out of economic depression by direct and personal assistance without an intermediary. Kudos to Andreessen on his vision eight years back — blockchain could be the breath of fresh air the world is waiting for.
