The [[link-rlp]] encoding is used throughout Ethereum to serialize nested
|
|
structures of Arrays and data.

_heading: Data Object @<rlp--dataobject>
|
|
|
|
A **Data Object** is a recursive structure which is used to serialize many
|
|
internal structures in Ethereum. Each **Data Object** can either be:
|
|
|
|
- Binary Data
|
|
- An Array of **Data Objects** (i.e. this recursively includes Nesting)
|
|
|
|
_definition: **Examples**
|
|
|
|
- ``"0x1234"``
|
|
- ``[ "0x1234", [ "0xdead", "0xbeef" ], [ ] ]``
