## Entrypoints
Each LIGO smart contract is essentially a single function, that has the following *(pseudo)* type signature:
Each LIGO smart contract is essentially a single main function, referring to the following types:
<!--DOCUSAURUS_CODE_TABS-->
<!--Pascaligo-->
```
(const parameter: my_type, const store: my_store_type): (list(operation), my_store_type)
```pascaligo group=a
type parameter_t is unit
type storage_t is unit
type return_t is (list(operation) * storage_t)
```
<!--CameLIGO-->
```
(parameter, store: my_type * my_store_type) : operation list * my_store_type

type return_t = (operation list * storage_t)
```

```

```
<!--END_DOCUSAURUS_CODE_TABS-->
This means that every smart contract needs at least one entrypoint function, here's an example:
Each main function receives two arguments:
- `parameter` - this is the parameter received in the invocation operation
- `storage` - this is the current (real) on-chain storage value
Storage can only be modified by running the smart contract entrypoint, which is responsible for returning a pair holding a list of operations, and a new storage.
Here is an example of a smart contract main function:

<!--END_DOCUSAURUS_CODE_TABS-->
Each entrypoint function receives two arguments:
- `parameter` - this is the parameter received in the invocation operation
- `storage` - this is the current (real) on-chain storage value
A contract entrypoints are the constructors of the parameter type (variant) and you must use pattern matching (`case`, `match`, `switch`) on the parameter in order to associate each entrypoint to its corresponding handler.
Storage can only be modified by running the smart contract entrypoint, which is responsible for returning a list of operations, and a new storage at the end of its execution.
To access the 'entrypoints' of a contract, we define a main function whose parameter is a variant type with constructors for each entrypoint. This allows us to satisfy the requirement that LIGO contracts always begin execution from the same function. The main function simply takes this variant, pattern matches it to determine which entrypoint to dispatch the call to, then returns the result of executing that entrypoint with the projected arguments.
> The LIGO variant's are compiled to a Michelson annotated tree of union type.

CameLIGO is a little different from other syntaxes when it comes to function
parameters. In OCaml, functions can only take one parameter. To get functions
with multiple arguments like we're used to in traditional programming languages,
a technique called [currying](https://en.wikipedia.org/wiki/Currying) is used.
Currying essentially translates a function with multiple arguments into a series
of single argument functions, each returning a new function accepting the next
argument until every parameter is filled. This is useful because it means that
CameLIGO can support [partial application](https://en.wikipedia.org/wiki/Partial_application).

Currying is however *not* the preferred way to pass function arguments in CameLIGO.
While this approach is faithful to the original OCaml, it is costlier in Michelson
than naive function execution accepting multiple arguments. Instead for most
functions with more than one parameter we should place the arguments in a
[tuple](language-basics/sets-lists-touples.md) and pass the tuple in as a single
parameter.

`fold` is an aggregation function that return the combination of a

The fold is a loop which extracts an element of the map on each iteration. It then
provides this element and an existing value to a folding function which combines them.
On the first iteration, the existing value is an initial expression given by the
programmer. On each subsequent iteration it is the result of the previous iteration.

(** Preliminary thoughts on ids:
I very much like the simplicity of http://gurno.com/adam/mne/.
5 three letter words means you have a 15 character identity, not actually more
annoying than an IP address and a lot more memorable than the raw digits. This
can be stored as a single integer which is then translated into the corresponding
series of 5 words.
I in general like the idea of having a 'skip' mechanism, but it does need to cost
something so people don't eat up the address space. 256 ^ 5 means you have a lot
of address space, but if people troll by skipping a lot that could be eaten up.
Should probably do some napkin calculations for how expensive skipping needs to
be to deter people from doing it just to chew up address space.
