With the Cardano team preparing for a transition to fully “decentralized block production” by 31 March, a researcher explained an interesting concept behind the “switch to decentralization.”
Cardano team members will contribute a set of “real, external causes of entropy” or a “public statement of randomness” as part of the transition.
Professor Alexander Russell, Senior Research Fellow of Input Performance HK, expanded on this by detailing the events that occur after the transition.
Technically, the network is looking for a “perpetual period of randomness generation,” in which all transactions posted to the blockchain before 7 April at 15:44:51 UTC “slot 151200 of epoch 258” will play a “distinguished role in the blockchain’s future.” In other words, their “accumulated hash value” would be mirrored in the “previous-block hash” from the first block generated “on or after this time.” This will “determine the transformation nonce” and thereby lead to the production of randomness.
Scientists and engineers at IOHK, according to Russell, will add to the origins of entropy. This will allow them to improve the “decentralised design of Cardano,” as project members have stated to the wider community. This involves a call for “stake pool operators and developers” to share in the “Cardano public declaration of randomness” and on-chain activities.
The researcher claims that
“This community exercise will establish the once-in-the-system’s-lifetime random 256-bit transition nonce that will herald the protocol’s official transition to decentralized operation.”
Scientists can insert metadata obtained from unusual public sources into transactions in order to increase the entropy factor. This will include “hashes of the NYSE’s closing prices on April 6” as well as real-time “seismic data” from the United States Geological Survey, the University of Athens, and the Japan Meteorological Society. The data gathered from these sources would span the “first 36 hours” of the epoch, and on April 5, “during epoch 258,” the team will trigger an entropy addition process.
Finally, the network has asked “more technical members” of the Cardano group to add to the randomness update on the network’s GitHub repository.
