A network of relayers make &#8220;collect calls&#8221; to paymaster contracts which can implement any logic for gas payment conditions. A dapp developer could choose to cover the cost of gas themselves, allow users to pay gas with a credit card or a token other than ETH, or enable ETH-less withdrawals from stealth addresses.

Rather than simply selling space, the <a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-vezwxf\" href=\"https:\/\/quadratic.page\/\">Quadratic Dollar Homepage<\/a> (QDH) lets users determine the relative scale of images on the page using two experimental blockchain voting mechanisms:<\/p>\n<ul role=\"list\" class=\"css-1ars4k6\">\n<li class=\"css-0\"><strong>Quadratic voting<\/strong> allows voters to indicate not only their preferences between a set of options, but the strength of those preferences. On QDH, holders of MOON, BRICK or\u00a0POAP tokens can cast as many votes as they have tokens, distributed between the images on the page in whatever way they choose.<\/li>\n<li class=\"css-0\"><strong><a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-vezwxf\" href=\"https:\/\/github.com\/appliedZKP\/maci\">Minimal Anti-Collusion Infrastructure (MACI)<\/a><\/strong> discourages bribery by making it impossible to verify how a user has voted. QDH accomplishes this by giving the user an &#8220;I&#8217;m being bribed&#8221; option when signing the vote transaction. This causes the transaction to be sent with an incorrect nonce, invalidating the vote. The user can then change their signing key to submit a second, valid vote.<\/li>\n<\/ul>\n<p class=\"chakra-text css-gi02ar\">Grantee Raman Shalupau has recently completed his funded work on the QDH user interface, MACI smart contracts and documentation. For a more in-depth look at how QDH works, this <a target=\"_blank\" rel=\"noopener\" class=\"chakra-link css-vezwxf\" href=\"https:\/\/www.youtube.com\/watch?v=b6VonnS8e1M\">demo<\/a> a provides a video walk-through of both the web interface and the back end components.
