Susucoin -------- Securing free speech. Abstract -------- Susucoin is a proof-of-work cryptocurrency designed with added transactional storage capacity for the purpose of archiving free speech. Susucoin has its own genesis block and is an independent blockchain built on wallet software forked from the bitcoin core project. The susucoin core team will be maintaining multiple full nodes and the project will be maintained through development on a github repository. Upstream bitcoin core security patches will be merged into the susucoin project. New features from bitcoin core will be merged in as needed, and the susucoin core team will develop new features which are unique to susucoin. We have already obtained first-party partnerships with multiple major anonymous free speech platforms to integrate APIs and features which will utilize susucoin in their communities. Technical --------- Susucoin, using the sha256 algorithm, provides a two minute target spacing with difficulty recalibration on every block. The difficulty calibration will be managed by Digishield from block 1 to 60; blocks 61-499 will use a hybrid Digishield/LWMA system; zawy12's LWMA algorithm will take over completely from block 500. Initial block reward subsidy will be 50 coins per mined block, with the subsidy halving interval set for every 945,000 blocks. Segwit is supported from block height 0. The total amount of susucoins is 105,000,000 with a 10% instamine on block 2 which will be used for susucoin development, marketing, and growth purposes. A total of 5 blocks have been premined, and checkpointed, before opening susucoin to the public. OP_RETURN will be set to a proposed 512 bytes in a later fork to help facilitate the meta purposes described in the subsection. We are working on a custom text compression algorithm and storage protocol and will announce details later before the fork to a 512 byte OP_RETURN. Integration ----------- The susucoin core team has already developed first-party partnerships with multiple anonymous free speech platforms to provide services and APIs to help enhance the archival capabilities of said platforms. Through on-demand requests, the text of posts will be saved to the susucoin blockchain and preserved for the ages. The susucoin core team will be providing a convenient blockchain viewer to support viewing data preserved in the susucoin blockchain. Writing data to the susucoin blockchain will provide a permanent record of the unmoderated thoughts of anonymous people from around the world. Susucoin will also utilize an API which will allow anonymous users to tip each other via a convenient web interface integrated into the anonymous free speech platforms which the susucoin core team has partnered with. Susucoin team is working on new text compression algorithms and storage protocols to more easily store thoughts and speech into the blockchain. Short-term Plan --------------- Setup block viewer and archived message viewer. Upgrade to a 512 byte OP_RETURN. Continue development of storage protocol and compression algorithms. Begin integration of susucoin into partnered communities. Mid-term Plan ------------- Partner and integrate with more free speech platforms. Build more api integrations. Get listed on exchanges. Long-term Plan -------------- Secure free speech at any cost.
