Introduction

Public blockchain is a mechanism through which networks can maintain a decentralized consensus on a shared country. Usually, this country holds, among other data, payment systems. Bets held byparticipants in the resulting economy work as their incentive to make the country widely available to others and to reject invalid transaction. In this virtuous cycle, the payment system is built on a consensus of decentralization, which only works becauseincentives created by the payment system itself.

Both the payment system and consensus can then be used for other purposes. As new applications for blockchain technology are envisioned, the demand for basic infrastructure continues to increase. At present, the two main obstacles to the widespread adoption of blockchain technology are poor scalability and lack of solidity environmental development. Cartesi's main contribution to the blockchain ecosystem addresses these two problems.

Work related

The closest work to Cartesi is TrueBit [Teutsch and Reitwießner 2017]. The connection between Cartesi and Truebit stems from the fact that both technologies move intensive calculations from chains and then, within the blockchain, use game verification [Feige and Kilian 1997] to efficiently resolve disputes on the results of these calculations.

Despite these similarities, many other design decisions distinguish these two technologies. TrueBit is based on WebAssembly [2018], an ISA VM designed by the W3C Community Group to support efficient web applications.1 Conversely, Cartesi is based on RISC-V [Waterman and Asanovic´ 2017a, b], an open ISA designed at UC Berkley for implementation by native hardware. WebAssembly and RISC-V are of similar complexity. The main difference is their position in relation to applications and operating systems. WebAssembly is designed to sit between the application and the underlying operating system.

RISC-V is instead intended to sit under the operating system and applications it supports. TrueBit options are consistent with a focus on expanding the power of smart contract computing, which tends to operate under very limited environments. Real-world applications, however, cannot exist separately.

The road to Cartesi

The reproducibility of our MVP is a cutting-edge VM.

This allows smart contracts to determine complex computing that is run off-chain on a Linux OS in a way that can be reproduced.

Verification

Cartesi's complete core allows for this complex calculation

it was decided for the truth on the blockchain, at a cost that was negligible, in a safe and decentralized way.

Infrastructure

Cartesi will publish and manage open source SDKs for world use. Create your own decentralized application without knowledge of the blockchain language and spread it to a network that develops from Cartesi Nodes.
