The Request itself is carried in the body of the HTTP message. Of course, additional HTTP-features and -headers (e.g. Content-Length: MUST contain the correct length according to the HTTP-specification. The term Primitive in this specification references any of those four primitive JSON types Content-Type SHOULD be 'application/json-rpc' but MAY be 'application/json' or 'application/jsonrequest' The Content-Length MUST be specified and correct according to the guidelines and rules laid out in Section 4.4, Message Length, of the HTTPspecification Content-Type: MUST be application/json. JSON can represent four primitive types (Strings, Numbers, Booleans, and Null) and two structured types (Objects and Arrays). You can now query the balances of both accounts and see the changed state: eth.getBalance("0xceee57f2b700c2f37d1476a7974965e149fce2d4") > 7425979000000000000 eth.Since JSON-RPC utilizes JSON, it has the same type system (see or RFC 4627). Done, we spent 21,000 of Gas (standard for sending funds) and the Transaction succeeded!.Paste the Transaction receipt hash to the search bar.This time the command succeeded, and a Transaction hash receipt was returned! Oh yeah!Īs we are connected to the Rinkeby network, we can take advantage of the Rinkeby GUI explorer to check the status of this transaction, gas spent, gas price, etc.
Ethereum light node vs remote rpc password#
But this way is safer as your password is only in a buffer and not stored in any log or visible on the screen. We could have also passed the password as a second argument instead of null. > Passphrase: > Repeat passphrase: > Address: )

In another terminal, we will create our second Ethereum account, exactly like in Part 1. In one terminal, remember to run a fully synced blockchain node: geth -rinkeby -datadir=~/.gophersland_ethereum_r1 -port=30304 -cache=2048 -rpc -rpcport=8546 -rpcapi=eth,web3,net,personal -syncmode=fast
Sending Ether to another account using the GETH CLI In order to send $15 worth of Ether, where 1 ETH = $200 (good old times…), you would make a transaction sending 0.0740 ETH which would be, and must be represented in Wei as, 74000000000000000. For example, I highly recommend the Ether to Wei online converter: Therefore, to be able to send a fraction of 1 ETH, the Ethereum foundation decided to create their own metric system where the smallest unit would be 1 Wei, and 1 Ether is 1e18 Wei.īut no worries, there are tools that can make your life easier. Apparently, calculations in finance are easier in integers. The Ethereum Virtual Machine does not support decimals or floats. I do, you might think, but wait for a second Lukas…why is 7.5ETH is displayed as 7500000000000000000 in the Geth console? Ether vs Wei
