TL;DR

Algorand was founded in 2017 before launching its mainnet and ALGO token in June 2019. The blockchain deals with the common scalability and consensus mechanism issues common to first and second-generation blockchains. Algorand’s main feature is its Pure Proof of Stake consensus protocol that randomly selects validators weighted by their staked ALGO coin.

Users who stake their ALGO have the chance of being selected to propose and validate a new block, which is then verified by a randomly-selected committee. Once the block is added to the blockchain, all transactions are considered confirmed. If the block is deemed bad, a new user is selected as a validator, and the process starts again.

The system’s main strength is its decentralization of power, as every single staker has the chance to be a validator. Apart from consensus, ALGO is also used for network transaction fees and to earn block rewards. If you want to buy or sell ALGO, you can easily do so through Binance’s convert feature or exchange view.

Algorand is a fairly new blockchain focused on improving scalability without sacrificing decentralization. This problem is common to many of the first and second-generation blockchains, such as Bitcoin and Ethereum. To achieve this, Algorand developed perhaps its most notable feature: the Pure Proof of Stake (PPoS) consensus mechanism. Along with its passive staking, both of these features have made Algorand a large market cap project popular with users seeking rewards.

Algorand is a blockchain network and project founded in 2017 by Professor Silvio Micali, a computer scientist from MIT. The mainnet network launched in June 2019 along with its native cryptocurrency, ALGO. As mentioned, the blockchain focuses on improved scalability and also supports smart contracts. The Algorand network is a public, decentralized, Pure Proof-of-Stake blockchain with support for customized layer-1 blockchains. These can be used to create blockchains tailored for specific uses. The project claims its technology is particularly useful for financial services, Decentralized Finance (DeFi), fintech, and institutions.

The Algorand Foundation is a non-profit organization launched in 2019 that funds and develops the Algorand network. It also carries out important work in the blockchain’s community, research, and governance.

For example, the Foundation has educated developers in universities and supported Algorand projects in its ecosystem with accelerator programs. However, technical development work is carried out by the private company Algorand Inc. The Algorand Foundation is also a large holder of ALGO, which it uses to fund its activities.

The key to Algorand’s scalability comes from its Pure Proof of Stake consensus mechanism. This protocol allows it to process many transactions quickly without sacrificing decentralization. Proof of Stake (PoS) blockchains are scalable but often at the cost of a small number of validators who have large stakes dominating block approvals. Proof of Work (PoW) has the same issue as large mining pools almost always win the race to create new blocks.

In contrast, Alogrand’s PPoS consensus mechanism chooses validators and block proposers randomly from anyone who has staked and generated a participation key. The chance of being chosen is directly related to the proportion of the participant’s stake of the overall amount staked.

Naturally, a small holder will have lower chances of being selected than a big holder. But unlike PoS blockchains, Algorand doesn’t require a minimum stake, which is a significant barrier to entry for the average user. With every staker who runs a node being a possible validator, the network’s security is more decentralized than with a chosen set of validators, such as in Delegated Proof of Stake (DPoS).

Proposal step

Once users have staked and generated their participation key, they become participation nodes. Communication between these nodes happens through Algorand relay nodes. The block proposal phase then selects multiple block proposers using a Verifiable Random Function (VRF), considering the proportion of each validator’s stake. Once block proposers are chosen, their identity is kept secret until the new block is proposed. This improves network security as bad actors cannot maliciously target the chosen validator. However, a proposer can demonstrate their VRF output along with their proposed block to prove their legitimacy.

Soft vote stage

Once a block is submitted, participation nodes are selected randomly to join the soft vote committee. This stage filters proposals, so only one candidate can add to the blockchain. Voting power on the soft committee is proportional to the amount each node has staked, and votes are used to select a proposed block with the lowest VRF hash. This means that it will be impossible to preemptively attack the proposer of a block, as the lowest VRF hash is a value that is impossible to predict.

Certify vote stage

Next, a new committee is created to check for double-spending and the integrity of transactions in the block from the soft vote stage. If the committee deems the work valid, the block is added. If not, the block is rejected, the blockchain enters recovery mode, and a new block is selected. There’s no slashing penalty for the leader who proposes a bad block, making it a controversial part of the PPoS consensus mechanism. The chance of a fork with Algorand is extremely rare, as only one block proposal reaches the certify stage at a time. Once the block is added, all transactions are then treated as final.

ALGO is the native coin of Algorand and has a maximum total supply of 10 billion coins to be distributed by 2030. New ALGO is sent to specific ALGO-holding wallets with each newly forged block. You need to hold at least 1 ALGO in a non-custodial wallet to receive these ALGO rewards. This reward can generate an APY of around 5-8% for ALGO holders and is distributed roughly every 10 minutes. This mechanism makes the ALGO coin one of the simplest cryptocurrencies to generate a passive income with, as you can “passively stake” the token.

Like many other native coins, ALGO has three primary use cases:

1. ALGO can be used to pay transaction fees on the Algorand Network. Compared to networks like Ethereum (ETH) and Bitcoin (BTC), Algorand has minimal fees. As of January 2022, it costs only $0.0014 per transaction.

2. ALGO can be staked to have a chance of being selected as a block proposer or validator.

3. ALGO can be held in a non-custodial wallet to earn rewards with every block that is successfully added to the chain.

The third use case provides a large incentive for the average user investing in ALGO. There’s no need to deal with a Decentralized Application (DApp) to stake your coins or a lock-up period to begin earning. It’s all automatically handled by smart contracts. Algorand also publishes a list of projects adopting the blockchain’s technology, many of which require ALGO to be used.

You can purchase ALGO on Binance in just two steps with a credit or debit card. If you already have crypto in your account, you may be able to swap directly for ALGO if it’s in a pair with the coin you hold. To begin, let’s look at using a credit or debit card.

As ALGO is not directly purchasable with fiat, you’ll need to purchase another token in an ALGO trading pair. BUSD is a good option, as its price is stable. You can see a complete list of available pairs further down this guide.

1. Log in to your Binance account and hover over the [Buy Crypto] header at the top left of the homepage. In the drop-down menu, select [Credit/Debit Card].

2. Next, select the fiat currency you’ll pay with your card in the top field. In the bottom field, choose your desired cryptocurrency. Make sure that it is in a pair with ALGO to trade for it directly.

3. Click [Continue] and accept any terms and conditions if it’s your first time purchasing with fiat.

4. Click [Add new card] or select a card already added to your account, and then follow the instructions for completing your payment.

5. Now, you’ll need to swap your BUSD for ALGO. You can do this easily with the [Convert] feature accessible under the [Trade] header.

6. Select the crypto you want to convert from in the top field and ALGO in the bottom. If you cannot see ALGO in the bottom field, it is not in a trading pair with your chosen crypto. Click [Preview Conversion] after entering the amount you want to swap.

7. You’ll now see a preview of the amount of ALGO you’ll receive with clear instructions on how to proceed. Once you have swapped, the ALGO will be in your Spot Wallet.

8. You can also trade using the Classic or Advanced exchange view. By hovering over the currently displayed pair, you can search for all available ALGO pairs.

1. To sell ALGO, you can use the Convert feature again. This time, select ALGO in the top field and the cryptocurrency you want to convert to at the bottom. Click [Preview Conversion] to check the exchange rate.

2. Once you’ve confirmed the amount you’ll receive, follow the instructions given to finalize your trade.

3. You can then convert to fiat using the same process so long as the coin you traded your ALGO for is in a fiat pair.

Like other alternative blockchains to Bitcoin and Ethereum, Algorand has focused heavily on scalability and decentralization. Its Pure Proof of Stake consensus mechanism provides a unique solution with VRFs, and many find this blockchain technology attractive for its success in decentralizing power.
