Sia: Simple Decentralized StorageDavid VorickNebulous ChampineNebulous 29, 2014 AbstractThe authors introduce Sia, a platform for decentral-ized Storage . Sia enables the formation of Storage con-tracts between peers. Contracts are agreements be-tween a Storage provider and their client, definingwhat data will be stored and at what price. Theyrequire the Storage provider to prove, at regular in-tervals, that they are still storing their client s are stored in a blockchain, making thempublicly auditable. In this respect, Sia can be viewedas a Bitcoin derivative that includes support for suchcontracts. Sia will initially be implemented as an alt-coin, and later financially connected to Bitcoin via atwo-way IntroductionSia is a Decentralized cloud Storage platform that in-tends to compete with existing Storage solutions, atboth the P2P and enterprise level. Instead of rentingstorage from a centralized provider, peers on Sia rentstorage from each other.
output i in transaction t is de ned as: H(tjj\output"jji) where H is a cryptographic hashing function, and \output" is a string literal. The block reward and miner fees have special output IDs, given by: H(H(Block Header)jj\blockreward") Every input must come from a prior output, so an input is simply an output ID.
