Pass the Blockchain Blockchain Developer - Ethereum CBDE Questions and answers with CertsForce

great, because they cut the middle man, run on a trusted platform, apply logic to the blockchain where already economic assets are running and thus allow peer to peer trade.

an amazing way to create new applications. Those applications run entirely separated from other applications on the platform and allow for logical interactions. They can't access any funds to add an additional layer of trust.

a new way of applying logical operations for banks and big financial institutions. This way they can reduce the staff while operating at increased security.

would be better, because it can reduce the amount of energy needed for mining.

would be worse, because it would increase the amount of energy needed for mining.

While the EVM is Sandboxed, it isn't as powerful as the Bitcoin Network, because it's not Turing Complete.

The EVM can't access hardware layers or anything outside a blockchain node because it's sandboxed.

The EVM is extremely powerful, turing complete and perfect for doing computational intensive things, because of the direct access to the graphics card.

can never become a mining node.

can always become a mining node.

can become a mining node, depending if the implementation has the functionality implemented.

True, but it's still good to use Ganache, or even a real private network for testing.

False, it's necessary to use Ganache or even a real private network for testing.

Keccack256 while internally to hash values it's easy to use the Dagger-Hashimoto to create a meaningful hash.

the Dagger-Hashimoto hashing while internally the EVM uses SHA256 which is an alias for Keccack256.

the Dagger-Hashimoto hashing while internally the EVM uses Keccack256 which is almost similar to SHA256, but has a different padding so produces different hashes.

To Protect the Public Keys by being cryptographically significant.

To Sign Transactions And To Derive an Address From.

To Generate An Address which can sign transactions.

can help to engage the community in testing your smart contracts and therefore help to find bugs early.

might be a burden as it is an administrative overhead mainly.

is completely useless. Who wants to test beta-ware software? It’s better to start with the bug-bounty program after the contract is released on the main-net.

Java, C++, Solidity and JavaScript, because the Ethereum Blockchain is completely language agnostic and cross compilers exist for every major language.

Solidity, Viper, LLL and Serpent, because those are high level languages that are compiled down to bytecode.

Solidity and JavaScript, because those are the official first implementations for Distributed applications and the Blockchain supports those languages fully.
