Permissionless Blockchain Explained and How Algorand Takes the Lead



Blockchain is simply defined as a chain of blocks that store information. The technology is designed to collect and store digital information in such a way that they cannot be backdated or tampered with. Blockchain’s purpose is to solve financial problems without the need for a central server.

Types of Blockchain

There are 3 major types of blockchains; Private Blockchain, Hybrid Blockchain and Permissionless/Public Blockchain.

Private Blockchain

Also known as permissioned blockchain, private blockchains contain several notable discrepancies from public blockchains.    

In private blockchains, participants must gain permission before they can access the network. Transactions are discreet and are only open to the network’s users permitted to access the network. They are more centralized as opposed to public blockchains.

Private blockchains are useful for businesses that wish to cooperate and exchange data, without their private company data visible to the public. The organizations that operate private blockchain have greater influence over participants. Examples include Ripple (XRP) and Hyperledger.

Hybrid Blockchain

Hybrid blockchain blends the privacy advantages of a private blockchain with the safety and decentralization advantages of a public blockchain. It offers businesses great versatility in deciding which data they choose to make public or private. 

This makes it possible for organizations to work with the transparency they seek, without losing privacy and security.

Permissionless/Public Blockchain

Public Blockchain is an open-source network that enables anyone to take part as users, developers, or miners. Every transaction that exists on a public blockchain is completely transparent, ensuring that anyone can inspect the details of a transaction, and that is why it’s called permissionless.

Public blockchains are built to be fully decentralized, without anyone regulating the transactions registered in the database, or how they were registered. Public blockchains can be particularly resistant to censorship because everyone is free to access the network irrespective of location, ethnicity, etc. This renders it incredibly impossible for authorities to clamp doors on them. Examples are Bitcoin, Ethereum, etc.

There has been a huge increase in the adoption of blockchain technologies in the past couple of years. Numerous businesses decided to build their initiatives on a permissionless blockchain as it helps in attracting and retaining users.

Permissionless blockchain gives room for anyone to join and transact. Information on this type of blockchain is open to the public, and full records of transactions are stored and endlessly modified which makes it difficult to control or hack. This particular blockchain is not managed by anyone, so you will stay anonymous because there is no need to identify yourself before you get an address and make transactions.

Finally, all public blockchains have a token linked with them, usually intended to incentivize and reward the particular network’s users.

Characteristics of Permissionless Blockchain

  • Transparency

Participants of a project built on a permissionless blockchain are encouraged to trust the project. An open network will provide users with access to all details, including passwords, right to view the network’s processed transactions, and how transactions are organized into blocks.

  • Decentralization

Permissionless blockchains are decentralized because there is no single authority that regulates activities on the network.  Activities are performed based on agreement protocols. This means that adjustments of any sort on the network will only be done if it is approved by 51% of its participants.

  • Digital Investments

Some incentives offer users tokens in a permissionless blockchain, which may boost or decline in value depending on the significance and nature of the blockchain the tokens belong to. These blockchains employ either financial or service tokens, depending on the purpose.

Now that we must have understood blockchain technology and its purpose, we will be delving back to the main topic of this article which is about How Algorand Takes the Lead among permissionless blockchains.

Algorand is a decentralized, permissionless blockchain with the major aim of building an economy that is free for everyone to access without any barrier.

On Algorand, users do not require any specific authorization to access and engage in the network.  Everyone is free to participate in the network, make transactions, and generate blocks. Information on the network is made public and anyone can read the generated blocks.

Also, Algorand is focusing on solving the three big obstacles of blockchain network; which are scalability, decentralization, and security.     

The Algorand team is aware that there wouldn’t be a widespread adoption if they do not provide what every blockchain enthusiast demands.

Decentralization, Scalability, and Security are key to launching an effective blockchain ecosystem and Algorand strives to add these three to its network, eventually solving the trilemma problem.

Algorand’s Decentralization

Unlike Bitcoin, Algorand solves the decentralization problem in a way that still maintains security. Utilizing a pure Proof-of-Work (PoW), Algorand created a protocol that randomly chooses who proposes and generates blocks.

Proof of work is a process that delays the production of new blocks. It is a computational problem that needs certain efforts to solve. However, the time required to confirm the outcome of the computational problem is much lesser than the time involved in solving the computational problem.

The proof-of-Work mechanism makes it very difficult to manipulate the blocks and in an event, a block is tampered with, it is necessary to recalculate the proof-of-work on each of the subsequent blocks which can be very stressful and costly. 

In the case of Algorand, there is no particular individual or group selected to perform a specific function in the network. In proportion to their stakes, every user is free to play any role in the network. Every owner of Algorand’s native coin ALGO is automatically qualified to engage in all of the network’s functions including block proposals and voting.

A user may opt to just transact, without having to engage in the consensus protocol. The Algorand protocol is structured to reduce participation costs; therefore, there is no limitation for users that wish to engage in the network.

Algorand Scalability

A blockchain is said to be scalable when it can handle millions of transactions in one second.

Algorand is solving the scalability problem by utilizing pure proof-of-stake to randomly select users that would verify and propose blocks. Users are sent private messages to verify their selection for consensus on the next block.

Bitcoin, which was the first to utilize blockchain also utilizes the proof-of-work protocol but unlike Algorand’s protocol, to reach consensus on the next block, users are required to solve cryptographic puzzles which can be stressful and time-wasting.

The consensus protocol of Algorand is capable of scaling to millions of users. It sustains a high transaction cost and doesn’t charge users extra costs. Block consensus is reached in perfect sync as the block is propagated to the network, and it happens in a matter of seconds.

Algorand Security

Security is very essential for every permissionless blockchain and the protection of the network and its users is taken extremely seriously by Algorand. Users require a blockchain where their assets are safe, and where they can safely build applications on.  At the consensus protocol level and network level, Algorand ensures protection from attacks at the network and consensus protocol level.



There are numerous blockchain projects in the digital space but none comes close to matching the level of efficiency, speed, freedom, and security Algorand provides. The Algorand project has a great team that is always open to improvisations and improvement on their network and it is no surprise that Algorand is currently the best permissionless blockchain.

What Happens To My Crypto When I Am Gone?



Ever wondered what will become of your digital assets when you finally go on to the great beyond?


We all know that a cryptocurrency is a digital asset with monetary value protected by unbreakable cryptography. This attribute makes cryptocurrencies attractive because it makes them a secure way to store wealth, but on the other hand, this may also be a major challenge because when a crypto holder becomes deceased, their virtual assets may become infinitely inaccessible. I bet this does not sound like a great succession plan. 

Cryptocurrencies are kept secure in virtual wallets. These wallets use a public key as a medium for sending and receiving cryptocurrencies. We also have what is called the private key. This is what gives the holder of a crypto wallet access to what the virtual wallet contains.

God forbid that a crypto owner passes on without disclosing his private key to his heirs. The resultant effect is that the content of his virtual wallet becomes inaccessible.


Not long ago, the curious people of the Cremation Research Institute conducted a study to find out if the owners of cryptocurrencies had succession or devolution plans for their virtual assets when they go on to the great beyond. It will interest you to know that it was  discovered that 89% of Cryptocurrency investors worry about what will become of their assets when they die. Ironically, this worrying has not given many cryptocurrency investors a cosmic kick up their back side to put plans in place for their virtual properties when they die. 

  It is alarming that only a few, 23%, have written Wills or have established a  Trust to help guide the appropriation of their digital assets when they are dead.

Coinmetrics revealed that our planet already boasts of 12,000 Bitcoin millionaires in the world. The same way crypto millionaires are on the rise, a sad number of crypto investors die every 365 days. It is unfortunate that, most times, their families are faced with the challenge of accessing the deceased’s millions in digital assets. In fact, Coincover disclosed that about 4 million Bitcoin which translates to about 40 billion USD has gone to flames following the death of a number of crypto owners.

source: Wall Street Journal

It then becomes disturbing that a sizable number of crypto investors, especially the millennials, are being negligent on this subject. The older generation appear to have put more plans in place as regards devolving their virtual assets upon their death.

The reason for this is not far fetched. There really is a dearth of digital estate services to help crypto holders in this area. It is a wise crypto attorney that will take this hint.

On a personal level, a crypto owner should endeavour to disclose his private key to a “trusted someone”. He will in turn secure it in a flash memory drive or with a commercial organization that secures same.

It is advisable to use a good commercial service that secures private keys.

Bitrefill Steps Up Consumer Loyalty with Bitcoin-Back Rewards




Bitrefill, in a recent announcement, unveiled a Bitcoin-Backed Rewards program, once again solidifying its resolve as a company with huge plans to step up consumer loyalty as a market leader.  

As a company founded in 2015, Bitrefill is a global vendor which allows purchasing Gift Cards or Mobile Refills from more than 2500 businesses in 170 countries. It has also stepped in for Nigerians as an easy solution to spend their crypto or gift cards. With Bitrefill, Nigerians and several other African countries to get eGifts & pay mobile bills quickly, safely, and privately with Bitcoin and other cryptocurrencies.

How Bitcoin-Back Rewards Work

Bitrefill users worldwide are able to accumulate a minimum of 1% back from every purchase, in Bitcoin. Users may even get up to 6% reward on some select products numbering 217 products as at the time of the announcement. The United States leads with 158 products while the users in the UK have 59 products to select from where they get to enjoy as much as 6% bitcoin-back rewards for purchases made in categories like eCommerce, retail, apparel, home, electronics, health & beauty, food, and restaurants. Plans are also in motion to expand this bumper loyalty rewards scheme to other regions such as the Middle East, Asia and Africa. 

Its style of reward system comes even when the smallest Satoshi (the smallest unit of a bitcoin, equivalent to 100 millionth of a bitcoin. Bitcoins can be split into smaller units to ease and facilitate smaller transactions) can be used to top-up airtimes or even pay for snacks in an online store. 

The decision to denominate the rewards program in Satoshis instead of USD or EUR or even NGN was made in order to preserve the value better if as a user you want to save the rewards for later. All you need to do to get sats back is to purchase gift cards, top-up your mobile phones with airtime, or purchase any digital voucher for your favourite brands, retailers, and online stores to have those sats stacking up.

Why does it Matter?

With bitcoin becoming the internet’s de-facto currency, uncensorable across borders, as a user of Bitrefill, your rewards being paid in Sats gives you interoperability to spending across several merchants that accept bitcoin should you decide to opt-out of the Gift Card option. 

While this next point may be easily dismissed as speculation on steroids, I’ll still go ahead to state it. Popular Bitcoin Bulls like Tim Draper, Anthony Pompliano who is more known as “Pomp” have continued to take bold bets on the future rise in the price of Bitcoin. They have even predicted it crossing over $100,000 per Bitcoin in the coming years. This resonates with me due to past experiences.

During the peak of Bitcoin’s price spike in December of 2017, I was fortunate to remember I still had an abandoned wallet with a few satoshi crumbs left in it. Having opened the wallet on the then Blockchain.Info and transacting with it while bitcoin price dangled around $157 per BTC, I left it with a few satoshis as balance. I deemed it as insignificant as it didn’t worth anything much then.

You know those 0.03 BTC balance which didn’t amount to anything substantial by then. But getting access to the same balance by December of 2017 gave me sweet $600.At the current rate of bitcoin, 0.03 bitcoin is worth $283 according to I have checked that kind of appreciation, only asset classes such as crypto, specifically Bitcoin could have yielded that kind of increment.

What Difference can this Bring to African User Communities

Some of the problems Africans have had to grapple with is financial exclusion, not exposed to varied choices as consumers and currency inflation. Bitcoin is designed to be deflationary, it’s become a safe haven for those who have experienced horrendous inflationary losses to their economy and subsequent crash on their currency value like Zimbabwe. Even Nigeria presently experiencing depreciation of its naira to the dollar already have her citizens recourse to bitcoin trading, this is noticed in the recent spike in Bitcoin P2P trading volume with Nigeria pushing Africa to surpass Latino American region for the first time.

Every consumer, asides having their needs met with good products and services also crave the feeling of being valued. With Bitcoin-Back Rewards by Bitrefill, this will most likely pique the interest of consumers in Africa even further.

And as typical of entrepreneurs who always follow the money, merchants’ interest in accepting Gift Cards in their respective stores should also see considerable growth. This growth should bring even more variety to consumers who always seek to exercise their sovereignty in the most diverse products available.

Bitrefill with this initiative may have initiated a chain reaction which benefits it especially as a brand and the loyalty industry in Africa as 73% of consumers are more likely to recommend brands with good loyalty programs. Why wouldn’t a user spread the good news to others who may have been yearning for the opportunity to “mine” this digital gold called bitcoin?

To start getting sats back, all you simply need to do is sign up for an account, supplying your email and preferred password and in just a few seconds, you’re ready to start earning Bitrefill’s much anticipated Bitcoin-Back Rewards. 

You may also download the easy-to-use Bitrefill app from Playstore and App Store

How To Position Yourself In The Crypto Industry



The cryptocurrency industry has grown over the years from a one cryptocurrency whose entire market capitalization was inconsequential to a multibillion dollar industry comprising of several thousands of cryptocurrencies and attracting the dons of the financial world into what they previously considered useless, valueless, and likely to end in a painful death.

All over the world, people are experiencing the liberation power which crypto offers especially in the areas of financial freedom and free speech. The influence which the ideal of crypto wields continues to resonate from nations to nations and this has resulted in the creation of one of the fastest growing industries. 

The rate of development in the   industry aside from regulatory limitations has been phenomenal. People, firms are creating new products which seek to make life better, easier and freer.
