The Security Ratio is an important indicator for assessing the security of a proof-of-work (PoW) chain, such as Bitcoin Cash.

By monitoring the Security Ratio, stakeholders in a PoW chain can make informed decisions about the security of the chain and take appropriate measures to maintain its integrity.

Calculation of Security Ratio is simple and can be determined as follows:

Security
ratio (SR)
= Total Block rewards Total Circulation supply * 1 000 000

Block rewards represent the total reward that a miner receives for mining a block. This includes not only newly minted coins, but also all transaction fees from that block.

Since the security ratio is calculated on a unit basis, it is independent of the currency expression, such as dollars.

Fixed reward for newly mined block in Bitcoin Cash

The Block reward Security Ratio focuses solely on the rewards associated with block minting.

This fixed reward for each mined block is an important factor in the economics of a PoW blockchain as it determines the rate at which new coins are created and added to the supply.

Block Mint reward
security ratio
= Block reward Circulation supply * 1 000 000

With each block mined, a certain amount of new currency is released = block reward. This amount may vary over time.

In a nutshell, to maintain current security over time, the decreases in block rewards must be offset by the revenue from transaction fees (grey full). Transaction fee revenue (grey solid) is a function of the number of transactions (blue) and their price.

The Fee Security Ratio focuses solely on the transaction fees paid by users, rather than incorporating newly minted coins as part of the block rewards.

This ratio provides a more accurate representation of the security level ensured by transaction fees alone. It can be calculated using the following formula:

Fee Security
ratio
= Total Transaction Fees Total Circulation Supply * 1 000 000

The Fee Security Ratio highlights the proportion of network security derived from transaction fees, making it an essential metric to understand a blockchain network's sustainability in the long run. As block rewards diminish over time, particularly in networks with a decreasing issuance schedule like Bitcoin, transaction fees become increasingly critical for maintaining network security.

Comparing Fee Security Ratios among blockchain networks with similar market capitalizations can provide valuable insights into the sustainability and long-term security of these networks, as it shows their reliance on transaction fees to incentivize miners and secure the network.

About Bitcoin Cash

Bitcoin Cash is a digital currency that was created in 2017 as a fork of the original Bitcoin blockchain. Like Bitcoin, Bitcoin Cash operates on a decentralized network of computers, but it aims to offer a faster and more scalable payment system.

One of the key reasons of the fork was to increase block size limit, which allows for more transactions to be processed per block compared to Bitcoin. This results in faster transaction times and lower fees, making Bitcoin Cash a popular choice for everyday transactions.

Because Bitcoin Cash is a relatively new and unregulated currency, its value can be volatile and subject to sudden fluctuations, and investors should be aware of the potential for fraud and theft.
