The KZG Ceremony Special Contribution Period ran from 01-16 April 2023. The Open Contribution Period allowed participants to make contributions in a way that was not possible during the Special Contribution Period. While only one honest participant is required to secure the output of the Ceremony, Special Contributions add additional assurances above and beyond an entropy standard contribution.
- In an isolated environment, the entropy can be calculated (e.g. On an airgapped computer, wiping out and physically destroying the hardware means it is unlikely that a malicious entity has extracted any entropy.
- It is unlikely that all the detailed documentation (explore the links below) associated with real reputations have been manipulated or fabricated by a malicious coordination entity. The records can be accessed by future observers.
- Risks associated with different hardware and Software Limits
- The difference in entropy generation is a good example. The Ceremony output is not compromised by a failure in the regular generation of entropy (eg. The hosted interface)
- Larger groups are more difficult for someone to feign than a single person. Participants were able to participate in a way that was not possible in the Open Contribution phase. This could be because they needed more time than usual or had a different way of generating the entropy.
This is a public record for the Special Contributions. It includes information about the methodology, the location of them in the transcript and links to media that document the contributions.
Cryptosat
The Cryptosat team started the Special Contribution Period with a contribution made from space aboard its Crypto 2 satellite. You can read about their contribution on their blog.

The KZG Marble Machine
The KZG Marble Machine consists of a series of tracks that represent different periods in Ethereum’s development. The machine uses 23 sensors that measure the small variations in marbles’ runs as well as environmental factors, to ensure randomness. Read xofee.eth‘s writeup here Or even 3D print your own machine.

12 – KZGamer: summoning Dankshard using a dice tower
Justin Florentine constructed a dice-tower that would collect entropy and also help him to determine the results of his table-top game. The dice-tower was a sealed container that rolled the die before collecting them and placing them in a chamber sealed with a Raspberry Pi. Then computer vision was used to read the dice which were used to determine the success/failure/damage of a given roll while adding the dice values to an internal entropy accumulator. The dice were then returned to the player through a trapdoor. By the end, 1024 bits had been collected of entropy and the SD card that was used on the Pi has been burned to destruction.

Catropy
Proof of Cat Or Catropy, is a project that collects entropy when cats play with a ball. This was achieved by embedding an embedded custom PCB. ESP-32 microcontroller Then, you can. MPU-6500 6-axis IMU The cat can then be given the ball by knitting it. The ESP-32 collects data from accelerometers, gyroscopes and entropy accumulators. This is then hashed into an entropy accumulator.
