This allowed participants to contribute in ways that may not have been possible in the Open Contribution period. While the Ceremony only needs a single honest participant to provide a secure output, Special Contributions provide additional assurances beyond a standard entropy contribution:<\/p>\n<ul role=\"list\" class=\"css-1ars4k6\">\n<li class=\"css-0\">computing over the entropy in an isolated environment (eg. on an airgapped machine, wiping and physically destroying hardware) means that it&#8217;s unlikely for a malicious entity to have extracted the entropy at any point.<\/li>\n<li class=\"css-0\">detailed documentation (explore links below) attached to real reputations are unlikely to all have been coopted or faked by a malicious coordinating entity. The records are available for future observers to explore.<\/li>\n<li class=\"css-0\">different hardware and software limits correlated risk<\/li>\n<li class=\"css-0\">differentiated entropy generation (eg. measuring an explosion) prevents the Ceremony output being compromised by some failure in the regular entropy generation (eg. the hosted interface)<\/li>\n<li class=\"css-0\">contributions involving large groups of people are harder to fake than those with only one person. This allowed participants to contribute in ways that may not have been possible in the Open Contribution period.

KZGamer &#8211; summoning Dankshard with a dice-tower<\/h2>\n<p class=\"chakra-text css-gi02ar\">Justin Florentine built a dice tower that could both collect entropy for the ceremony and help determine the outcomes of his table-top games. The dice tower was a sealed box which rolled the dice before collecting them in a sealed chamber in which they were photographed by a Raspberry Pi (and camera). 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. A trapdoor then opened to return the dice to the player. By the end of the game, 1024 bits of entropy had been collected and the SD card used in the Pi was burned until destruction.<\/p>\n<p class=\"chakra-text css-gi02ar\"><strong>Powers of Tau Pubkeys:<\/strong><\/p>\n<div class=\"chakra-stack css-1jx0in4\">\n<pre><pre style=\"color:white;font-family:Consolas, Monaco, &quot;Andale Mono&quot;, &quot;Ubuntu Mono&quot;, monospace;text-align:left;white-space:pre;word-spacing:normal;word-break:normal;word-wrap:normal;line-height:1.5;font-size:1em;-moz-tab-size:4;-o-tab-size:4;tab-size:4;-webkit-hyphens:none;-moz-hyphens:none;-ms-hyphens:none;hyphens:none;padding:1em;margin:0.5em 0;overflow:auto;background:#011627\"><code class=\"language-text\" style=\"color:#d6deeb;font-family:Consolas, Monaco, &quot;Andale Mono&quot;, &quot;Ubuntu Mono&quot;, monospace;text-align:left;white-space:pre;word-spacing:normal;word-break:normal;word-wrap:normal;line-height:1.5;font-size:1em;-moz-tab-size:4;-o-tab-size:4;tab-size:4;-webkit-hyphens:none;-moz-hyphens:none;-ms-hyphens:none;hyphens:none\"><span>2^12: 0x9157bfd6d53e6f9cd427aa84acfe47e7f1224ab99ac2c606ccea8dec3ba85a73d3b29c74422461697e9d86e36baa7f8d02add99798a40e2f32c2cd7185b13ad86f57fb7df418c708727d9ff2f85cc220f66353408151075785caf78f3b6c4dbe\n<\/span>2^13: 0x92ae7793b9ba21e8dcfa88e4722acd8b5282d0ad9f9407db13b966797d8a98474986e3beb0d6271fb4fe68ea485dd8ff05144addcf1af56f69a2c26ad5e6009b481e77f431247a03c22e458da0f5264e1d0db7e3e5aa6f1fc93cf539271b77fc\n<!-- -->2^14: 0x908b21c002bb0a336e8c22da6c5f3ae688c7319f72045eff8817233fbb3c29a652f04a435e4392507462b4530f80db5c102844255ec594c1b15b3b2ae9f3a3797436846f754e8769f4c5450902d2f3d704971fb998881aeea998c64d37198391\n<!-- -->2^15: 0xa64a105c21f2d9cff3799ef38203ae6da23b12be6949ab8dd136244de4af918b6bdb4d69537af464c3b3a156f89655720b827a331ad71d3a43ce9420b7b81be6e81b69009824de01b618ea65d2512da82215d75c99fbe9e010df5c51279416e6\n<\/code><\/pre>\n<\/div>\n<p class=\"chakra-text css-gi02ar\"><img decoding=\"async\" alt=\"\" src=\"https:\/\/storage.googleapis.com\/ethereum-hackmd\/upload_c551cbb24a3f687a0d8c9f3bfda1979a.png\" class=\"chakra-image css-hw6q2r\"\/><br \/>\n<img decoding=\"async\" alt=\"\" src=\"https:\/\/storage.googleapis.com\/ethereum-hackmd\/upload_3a6f24c5378c59f5b16dcd9cc9183b70.png\" class=\"chakra-image css-hw6q2r\"\/><br \/>\n<img decoding=\"async\" alt=\"\" src=\"https:\/\/storage.googleapis.com\/ethereum-hackmd\/upload_d45d8f97f508efa34ea6e60e6de9389d.jpg\" class=\"chakra-image css-hw6q2r\"\/><\/p>\n<h2 class=\"chakra-heading group css-1kpzc4q\" id=\"13---catropy\" data-group=\"true\"><a class=\"chakra-link css-128fqrf\" aria-label=\"13   catropy permalink\" href=\"#13---catropy\"><svg viewbox=\"0 0 24 24\" focusable=\"false\" class=\"chakra-icon css-173jpr1\"><g fill=\"currentColor\"><path d=\"M10.458,18.374,7.721,21.11a2.853,2.853,0,0,1-3.942,0l-.892-.891a2.787,2.787,0,0,1,0-3.941l5.8-5.8a2.789,2.789,0,0,1,3.942,0l.893.892A1,1,0,0,0,14.94,9.952l-.893-.892a4.791,4.791,0,0,0-6.771,0l-5.8,5.8a4.787,4.787,0,0,0,0,6.77l.892.891a4.785,4.785,0,0,0,6.771,0l2.736-2.735a1,1,0,1,0-1.414-1.415Z\"\/><path d=\"M22.526,2.363l-.892-.892a4.8,4.8,0,0,0-6.77,0l-2.905,2.9a1,1,0,0,0,1.414,1.414l2.9-2.9a2.79,2.79,0,0,1,3.941,0l.893.893a2.786,2.786,0,0,1,0,3.942l-5.8,5.8a2.769,2.769,0,0,1-1.971.817h0a2.766,2.766,0,0,1-1.969-.816,1,1,0,1,0-1.415,1.412,4.751,4.751,0,0,0,3.384,1.4h0a4.752,4.752,0,0,0,3.385-1.4l5.8-5.8a4.786,4.786,0,0,0,0-6.771Z\"\/><\/g><\/svg><\/a>13 &#8211; Catropy<\/h2>\n<p class=\"chakra-text css-gi02ar\"><a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-vezwxf\" href=\"http:\/\/web.archive.org\/web\/20230501054531\/https:\/proofof.cat\/\">Proof of Cat<\/a> or Catropy is a project to collect entropy from cats playing with a ball.
