Please see the [test suite's readme](https://github.com/ubiq/rpc-tests/blob/master/README.md) for details. |
 | `rlpdump` | Developer utility tool to convert binary RLP ([Recursive Length Prefix](https://github.com/ubiq/wiki/wiki/RLP)) dumps (data encoding used by the Ethereum protocol both network as well as consensus wise) to user friendlier hierarchical representation (e.g. `rlpdump --hex CE0183FFFFFFC4C304050583616263`). |

 One of the quickest ways to get Ethereum up and running on your machine is by using Docker:
 
 ```
-docker run -d --name ethereum-node -v /Users/alice/ethereum:/root \
+docker run -d --name ubiq-node -v /Users/alice/ubiq:/root \
            -p 8588:8588 -p 30388:30388 \
-           ethereum/client-go --fast --cache=512
+           ubiq/client-go --fast --cache=512
 ```
 
 This will start gubiq in fast sync mode with a DB memory allowance of 512MB just as the above command does.  It will also create a persistent volume in your home directory for saving your blockchain as well as map the default ports. There is also an `alpine` tag available for a slim version of the image.

+Package hexutil implements hex encoding with 0x prefix.

+Encoding Rules
+
+All hex data must have prefix "0x".
+
+For byte slices, the hex data must be of even length. An empty byte slice
+encodes as "0x".
+
+Integers are encoded using the least amount of digits (no leading zero digits). Their
+encoding may be of uneven length. The number zero encodes as "0x0".

-
-The Registrar is used by
-* the roundtripper transport implementation of
-url schemes to resolve domain names and services that register these names
-* contract info retrieval (NatSpec).
-
-The Registrar uses 3 contracts on the blockchain:
-* GlobalRegistrar: Name (string) -> Address (Owner)
-* HashReg : Key Hash (hash of domain name or contract code) -> Content Hash
-* UrlHint : Content Hash -> Url Hint
-
-These contracts are (currently) not included in the genesis block.
-Each Set<X> needs to be called once on each blockchain/network once.
-
-Contract addresses need to be set the first time any Registrar method is called
-in a client session.
-This is done for frontier by default, otherwise the caller needs to make sure
-the relevant environment initialised the desired contracts
