Under the hood, the `prepare phase2` command calculates the encrypted evaluation of the Lagrange polynomials at tau for `tau`, `alpha*tau` and `beta*tau`. It takes the beacon `ptau` file we generated in the previous step, and outputs a final `ptau` file which will be used to generate the circuit proving and verification keys. +--- +**NOTE** + +A ptau file for bn128 with the peraperPhase2 54 contributions and a beacon, can be found here: + +https://www.dropbox.com/sh/mn47gnepqu88mzl/AACaJkBU7mmCq8uU8ml0-0fma?dl=0 + +There is a file truncated for each power of two. + +The complete file is [powersOfTau28_hez_final.ptau](https://www.dropbox.com/sh/mn47gnepqu88mzl/AADgFSy_UnsSoDwOPy64tpCWa/powersOfTau28_hez_final.ptau?dl=0) which includes 2**28 powers. + +And it's blake2b hash is: + +55c77ce8562366c91e7cda394cf7b7c15a06c12d8c905e8b36ba9cf5e13eb37d1a429c589e8eaba4c591bc4b88a0e2828745a53e170eac300236f5c1a326f41a + +You can find more information about the ceremony [here](https://github.com/weijiekoh/perpetualpowersoftau) + +The last ptau file was geneerated using this procedure: + +https://www.reddit.com/r/ethereum/comments/iftos6/powers_of_tau_selection_for_hermez_rollup/ + +--- + ### 8.
