Proof-of-burn is a novel method for reaching consensus on the blockchain, and given its promise of maintaining decentralization, and lack of resource intensive mechanism it could become increasingly used. While proof-of-burn proponents say it doesn’t use resources, critics claim that proof-of-burn does involve resource waste in as much as the resources used to generate the burnt coins is wasted. “Difficulty bomb” referred to the increasing difficulty and time needed to mine Ethereum blocks to discourage a fork after the blockchain transitioned to proof-of-stake. One of the major criticisms is that PoB requires a large initial investment to participate.

She is a financial therapist and is globally-recognized as a leading personal finance and cryptocurrency subject matter expert and educator. Another potential issue is that people could use PoB to hoard coins. This would limit the available supply and could lead to an increase in value. While this is good for those who hold the coins, it is not good for the overall health of the currency. One of the main criticisms of Proof-of-Work is that it requires a lot of energy to operate.


The chief advantage of a Proof of Burn protocol is that it uses a fraction of the energy that a Proof of Work-based blockchain uses. Indeed, because of the aforementioned computational arms race that a Proof of Work algorithm cultivates between its nodes, mining on the network progressively demands more and more resources to participate in. Only the correct answer to the cryptographic puzzle will produce the accurate record of the transaction to be added to the distributed ledger that is the blockchain. Proof of Burn derives its name from a process called Coin Burning, in which tokens are sent to public addresses without private keys, rendering them forever unretrievable. These public addresses, known as Eater Addresses, are often randomly generated without private keys – meaning no one ever had, nor ever will have access to the funds stored inside them. This is why the process is called “burning” — you’re essentially consigning a certain amount of currency to oblivion just as effectively as you would be by setting fire to all the notes in your wallet.

This would give them control over the network and could lead to instability. The burning of cryptocurrencies and tokens is accomplished virtually, so no mining gear or hardware is required. The sector has a significant imbalance in terms of benefits due to the fact that centralized hardware manufacturers have been eliminated. The strength of burnt coins “decays” or devolves over time, with each new block produced. This encourages miners to engage in frequent activity rather than making a one-time, early investment.

Example of Proof of Burn

A block is committed only when all blockchain nodes agree on a set of transactions that they find acceptable. The third attempt at developing a system to combat fraud on a blockchain while also improving the utility of the blockchain as a tool for transactions is proof of burn. The primary and most widely utilized method for preventing fraudulent activity on a blockchain is proof of work and proof of stake, which is the technique used by Bitcoin. The proof-of-burn protocol is based on the idea of “burning” coins held by miners who have granted them mining rights. PoB allows miners to burn digital currency in order to gain the right to write blocks. To burn coins, miners have to send them to a verifiably unspendable wallet address, essentially permanently removing them from circulation.

The idea behind PoB is that it creates scarcity for the new tokens, which then drives up demand. One of the main advantages of PoB is that it does not require expensive mining hardware to distribute coins or secure its network. Now, due to the fact that this is autonomous and given the decentralized nature of blockchain networks, an automated mechanism is required in order to ensure that the nodes agree on truly valid transactions. This is a task that is typically performed by consensus mechanism algorithms.


Proof-of-Burn does not have this issue, making it more environmentally friendly. The process of “digging” in PoW does require a lot of energy, but this energy is wasted and should not be considered productive. This technique may be utilized for a variety of things, including adding value to a new cryptocurrency or burning unsold cryptocurrencies in ICOs. A Proof of Burn is a variant form of consensus that attempts to address the proof of work system’s high energy usage. Often, proof of burn is called a proof of work system, without energy waste.

It is also questioned that mining power simply goes to those who are willing to burn more money. Depending on how the PoB is implemented, miners may burn the native currency of the Blockchain application or the currency of an alternative chain, such as bitcoin. There are a few ways to implement a crypto burn meaning consensus mechanism. In some cases an existing Proof-of-Work coin, most typically Bitcoin, can be burned in exchange for the PoB coin. In other cases it is the actual PoB coin that is burned in order to gain increased mining privileges. Amid the dynamically changing status of the blockchain, a consensus mechanism ensures that only the true state of the system is maintained.

Since it is easier to invest in virtual mining rigs than in physical ones, coin mining is less centralized. The first drawback is that the power consumption of PoW is very high. Computational power is employed to solve a math problem in exchange for remuneration. Greater the money a miner spends to solve the problem, the greater the chances that they will be allowed to mine blocks. The key is to use a stream of true randomness – see below for where that comes from!


We’ve even talked about pure-blockchain topics like Forking and Sharding. As anyone who has paid any meaningful attention to the cryptocurrency market will tell you, the devil is always in the details. This may be done if it is sent to somewhere where it can’t be spent. So miners send these coins to such addresses from where they can’t be used. It is sent to a public verifiable address where it cannot be accessed and thus can not be used.

Disadvantages of Proof of Burn

In Blockchain no central authority is present to validate and verify the transactions, yet every transaction in the Blockchain is completely secured and verified. The transactions are considered to be secured and verified because of the consensus protocol which is a core part of any Blockchain network. The amazing answer, as far as I can honestly work out, is that in long-run equilibrium, the burn rate is just such as to make hardly any of this demurrage real demurrage at all! [The implicit remurrage of burning almost exactly cancels the explicit demurrage of network-strengthening coin-[re-]minting! (Or if you like, the implicit demurrage of inflationary fresh-coin-minting.) Either way, we seem to get the possibility of amazing network strength “for free”! ] This opens up the shocking possibility of turning up the demurrage/inflation rate to startlingly high levels – 5% of money stock / year, 10% of money stock / year…

This is done by sending the coins to a special address that can only burn them. Once the coins have been burned, they are destroyed and cannot be used again. The new coins are then created by taking the total number of burned coins and dividing it by the total number of coins in circulation. Being one of a few consensus mechanisms, proof of burn is an algorithm implemented by a blockchain network to guarantee that all involved nodes come to an agreement. When coins are destroyed on the blockchain we refer to them as being burned.

It selects transaction validators depending on the number of coins staked or locked up to the network. The hash created by a particular function will be the same length regardless of the size of the underlying data set.

Proof-of-burn is a blockchain consensus mechanism with minimal energy consumption, compared to proof-of-work . Decentralized platforms employing the PoB method ensure miners reach a consensus by burning coins. Burning is the process of permanently eliminating cryptos from circulation. Although the practice reduces inflation, PoB-powered blockchains use it to validate transactions. The answer is straightforward enough, though its implications are quite broad and in some ways surprising. If burning coins, rather than buying a lot of kit from a mining rig supplier, is the expense incurred by a miner to compete for the revenue stream, the same economic principles apply.

  • We’ve put out a few guides on some of the bigger currencies, explaining how they work and how you can purchase some for yourself.
  • There are in fact some further issues, to do with making sure it’s not cheap for a miner to re-exhibit their proof on multiple competing chains.
  • Essentially, this burning activity allows the network to be flexible and participants are rewarded for their actions (both burning other people’s coins and their own).
  • Proof-of-Burn is a consensus algorithm that uses the burning of coins to create value.
  • In terms of negatives, we once again have to draw our attention to the problem of centralization.
  • Doing so would boost the value, removing any incentive to perform these activities.

You can learn more about this concept in our article on this topic. The idea is that miners should show proof that they burned some coins – that is, sent them to a verifiably unspendable address. This is expensive from their individual point of view, just like proof of work; but it consumes no resources other than the burned underlying asset. To date, all proof of burn cryptocurrencies work by burning proof-of-work-mined cryptocurrencies, so the ultimate source of scarcity remains the proof-of-work-mined “fuel”. The most well-known type of consensus-generating algorithms is called proof of work .

What are the Proof-of-Work Alternatives?

The coin distribution is more fair compared to all other consensuses. They invest in the coins by locking up some of their coins as a stake. When the coin is burnt its availability decreases leading to a potential increase in the value of the coin.

Unsold ICO Coins

A block is written only when the blockchain nodes agree on a set of transactions that the nodes consider valid. A potential issue with PoB is that it could be used for speculation. This means that people could buy up coins, wait until they have a large supply, and then use them to create blocks.

How Does Proof of Burn Work?

As previously stated, the more coins you burn, the more likely you are to qualify for the selection process. Although this seems to be a good alternative to Proof-Of-Work, it still wastes a lot of resources by requiring more coins to be burned. Instead of putting money on computer equipment, the owner burns cryptocurrency coins. The coins are sent to an address where they are irretrievably lost.

Crypto Safety 101: How to Protect your Crypto

There’s still time of course for proof of burn to prove itself, but so far it seems that using coin burn as a feature may be more beneficial than just as a means to consensus. Proof of burn is a novel consensus method that outlines the interesting ways in which the cryptocurrency space is evolving. It essentially allows new coins to bootstrap off of existing established networks, like Bitcoin, to gain the benefits that they’ve already achieved. In the case of Ripple and Request Network, the process is different.
