I just want to invest the most potential project, so I want to know which is better, the below words are from Tau-Chain developer, is there any technical talent from Ethereum community comparing these two projects from technical perspective?
Quote from Tau-Chain developer:
"Now let me list five major differences:
Ethereum client is fixed, meaning the network's protocol cannot change with time. It is hard-coded, and if one day users would like to change its behavior, they will probably require a hard-fork of Ethereum's blockchain. On the other hand, Tau client's behavior and code is itself on-chain. Think open a GitHub repository with a code and all it is doing is downloading from GitHub its own code and executing it. This is exactly what Tau client is doing: every block contains its own code, including the conditions for accepting the next block. Therefore we get maximum flexibility not only for apps over Tau but for Tau itself.
Ethereum's rules are predetermined by their developers. Tau will come out with no rules at all. Its users will set its behavior. At this sense, tau begins with total equilibrium among its participants, a priori.
Ethereum's applications are written in a Turing complete language, which disables the whole magic of proofs over a given code, as emphasized in many places.
Ethereum does not support separate contexts: everyone executes all code. Therefore, it is impractical to supply general purpose or HPC software over Ethereum. On the other hand, Tau has separate contexts, so one may subscribe to a context (like installing an app from Appstore/GooglePlay) without interfering with other contexts. Yet, that context can reference other existing contexts and reuse their code.
Ethereum's model requires a coin ("fuel"). Tau doesn't need a coin: the users can agree on the economic characteristic of the network and define any kind of incentive they find adequate, whether globally over the whole network or over their local Tau client."
