Merged mining, sometimes called auxiliary proof of work, is the process of mining two or more chains at the same time. Essentially the same proof of work can be used as assurance on multiple systems. This involves a parent chain and a child chain, when the child chain essentially inherits some of the security characteristics of the parent.
Dogecoin hash-rate wars of and implications for Bitcoin vs. This report will focus on situations where Bitcoin is the parent chain and a commitment hash from another chain is located somewhere inside the Bitcoin blockchain.
In these cases no change is required to Bitcoin, which does not need to be aware of the other system. However, the other chain needs to be structured to accept and receive the Bitcoin block header as evidence of the work. Miners can then receive two types of rewards for producing valid blocks, the normal Bitcoin reward and a reward for mining on the alternative chain. It is also important to explain and identify two theoretical types of merge mining: regular merge mining and blind merge mining.
Regular merge mining is conducted by Bitcoin miners, while blind merge mining can normally be conducted by anyone, who then pays Bitcoin miners in fees. Miners are incentivised to check the validity of blocks in both chains. Miners typically only check the validity of blocks in the parent chain and are not concerned about the child chain.
Miners are rewarded in Bitcoin for the work and do not lose any rewards if there is an issue on the child chain. Blind merge mining is often thought of as superior to regular merge mining from a security perspective, as blind merge mining can prevent risks from the child chain impacting the parent. For example, in some systems a bug or issue in the child chain could cause a cessation of block production or a blockchain re-organisation in the parent chain. Another potential problem with regular merge mining is that validation costs in a child chain could be prohibitively expensive for example, due to large block sizes , which could cause mining centralisation in the parent chain.
Unfortunately, as far as we are aware, currently merged mining is primarily conducted the regular way, and blind merge mining is relatively rare. Veriblock can also be considered as a blind merge mining scheme, although its usage of Bitcoin blockspace makes the mechanism somewhat controversial.
In this report, we are interested in the regular merge mining. Cases where the alternative chain commitment hash is inside the block header or coinbase transaction and not just in any transaction. The reason we have chosen to do this is because looking for evidence of hashes of alternative chains in the coinbase transaction is far easier than looking in all transactions.
In addition to this regular merge mining may be more significant from a security point of view, as we explained above. Therefore the prevalence of regular merge mining may be interesting. As for where the miners include these hashes from alternative chains, they must be in a specific location to avoid any doubt over which commitment is the true one.
There is limited choice available for such commitments, the block header space is pretty much all used up and therefore the coinbase transaction is used. We have identified two spaces within the coinbase transaction for the alternative chain commitments:. In this report we have attempted to assess the prevalence of merge mining in these two parts of the coinbase transaction over time.
As Figure 1 below illustrates, the prevalence of these outputs has accelerated dramatically in recent years. In YTD, on average there are 2. As we explained back in March , the SegWit upgrade works by adding the merkle root of the witness merkle tree in the coinbase transaction.
This may indicate that regular merge mining is becoming increasingly popular. Figure 1 — Number of zero value outputs in the Bitcoin coinbase transaction Average over 1, block periods.
As the chart illustrates, with the exception of SegWit, we have identified the RSK blockchain as the primary cause of this growth and highlighted it in red. We were able to identify these due to the presence of an RSK related tag in the output. In Figure 2 below, we look at adoption of RSK in more detail.
Figure 2 — Proportion of Bitcoin blocks with an RSK commitment in the coinbase transaction Average over 1, block periods. As other traders hit your bids and lift your asks, you must hedge yourself in the spot market.
A trader buys ETC7D contracts at 0. You are now short ETC. You now have 0 ETC exposure. You are still quoting a two-way market of 0.
A new trader decides to sell contracts at your Bid price of 0. Your portfolio is flat. You have realised a profit of 0. This is the simplest form of market making. You take the underlying spot price, apply a spread, and dynamically hedge whenever anyone trades on your quotes.
If you hold a futures contract over settlement, it will expire and leave you with no exposure. Your goal is to be market neutral, so during the settlement calculation period you need to reduce your spot hedge to 0. BitMEX will take the spot prices on Poloniex each minute and compute an average, which then becomes the settlement price.
To capture the unrealised profit of 0. Your trading program will split your spot hedge into 30 slices, or 10 ETC. Each minute you will sell 10 ETC at market to match the price used in the settlement calculation. Because the settlement calculation uses the last price each minute, you theoretically will match the settlement price. Any difference between your sell trade executions and the prices used in the settlement calculation is called Slippage.
In this example, if your Slippage is more than 0. In Lesson 2, I will explain how to calculate a Basis and Skew. These two variables tie in closely with inventory management.
