What is cleos? Is it the main eos wallet like how bitcoin core is to bitcoin?

Question

Is cleos the most trustworthy wallet like how bitcoin core software is to bitcoin?

Answer 1

No, cleos is not a wallet software; it's a CLI tool interfacing with nodes and wallet services.

EOSIO software is akin to Bitcoin Core, which comes with bitcoind, bitcoin-qt, and bitcoin-cli. These are comparable to nodeos, keos, and cleos, respectively. So, if you want to draw parallels with other blockchains, cleos is somewhat similar to bitcoin-cli in Bitcoin Core or with geth in Go Ethereum.

Perhaps the diagram below from the documentation may clear up how those tools interact with each other:

Answer 2

Let's see the definitions of the two softwares.

From eos developers guide: cleos is a command line tool that interfaces with the REST API exposed by nodeos.

From wikipedia (the best description i can get): Bitcoin Core includes a transaction verification engine and connects to the bitcoin network as a full node.

From this description, bitcoin core can be seen as cleos + nodeos + keosd. Obviously cleos (aswell keosd and nodeos) is developed by block.one (eosio) so it should be reliable...
