Monero-p2pool-Output-Stats

The p2pool-output-stats.R script computes the number of p2pool payout transaction outputs on the Monero blockchain. It allows a user to choose the block height interval to analyze. The script outputs to the console:

• Number of blocks found by p2pool
• Summary statistics on number of payout outputs per block found by p2pool
• Total number of transaction outputs (subject to some rounding errors)
• Number of p2pool payout transaction outputs

In the directory where the script is run, it also creates two csv files:

• blockchain-stats-begin_height-to-end_height.csv
• miner-payouts-begin_height-to-end_height.csv

Steps to run:

1. Install R

2. Install the data.table, RJSONIO, and RCurl R Packages. The easiest way to do this is to start an R session by typing R in your terminal and then input install.packages(c("data.table", "RJSONIO", "RCurl")) into the R prompt. R may ask you to confirm that you want to create a user-level directory to store the packages. The R packages will be compiled from source code by default if you are using Linux. Then exit the R session by typing quit("no").

3. You must have a Monero node fully synced and running. By default, the R script will assume that monerod's RPC interface is available at http://127.0.0.1:18081.

4. You must have the monero-blockchain-stats utility somewhere on your computer. The easiest way to get this is to download the Monero CLI Wallet. The monero-blockchain-stats utility is bundled with the CLI Wallet.

5. To run the script, in your terminal input Rscript <path/to/p2pool-output-stats.R> <initial_block_height> <end_block_height> "<path/to/monero-blockchain-stats>". For example, if the path to p2pool-output-stats.R is ~/misc-research/Monero-p2pool-Output-Stats/p2pool-output-stats.R, the initial block height is 2721396, the end block height is 2786779, and the path to monero-blockchain-stats is ~/monero/monero-blockchain-stats, then the input into terminal would be Rscript ~/misc-research/Monero-p2pool-Output-Stats/p2pool-output-stats.R 2721396 2786779 "~/monero/monero-blockchain-stats".
