ffc0189f19 default target 
takes a couple seconds on my laptop to generate a proof of work with
this target
 2016-11-18 14:07:27 -08:00
Eitan Chatav
2864152e15 use 256 bit target for proof of work 
* SHA256 produces 256 bits pseudo-randomly uniformly, so you may
compare to a 256 bit target to get a proof of work
* If you pretend that the hash and targets are both integers between 0
and 2^256 - 1, then the target partitions the range into passing and
failing segments.
* In order to match the use of the `get_uint16` function from
`ocplib-endian`, the easiest way to encode `target` is as a `int list`
which works if not ideal
* This seems like the same thing bitcoin does; difficulty there is
actually not a primary notion but is calculated from a 256 bit target,
which is what gets adjusted over time

3b071cac46 Merge branch 'work-on-script' into 'master' 
Tracing interpreter and type checker

Implements:
  * a typechecker that optionally dumps the types of each instruction
  * an interpreter that drops the stack at each execution step

Incidentally:
  * adds some RPCs to pretty print the traces
  * drops floats and imperative structures from the language
  * fixes the typing of `FAIL`

a55f31bc9b Merge branch 'resolve_prefix' into 'master' 
Implement a minimal "completion" service.

The use of Base48 encoding allows to efficiently implement a "completion" mechanism for blocks, operations, public key and contract identifiers. For instance:

```
> ./tezos-client complete eeHfgnr9QeDN
eeHfgnr9QeDNvcMgSfATNeDeec4KG4CkHHkNNJt5B9xdVmsxhsHNR
```

This command returns all the identifiers matching the given prefix. Adding the option `-unique` let the command fails when there more than one possible completion.

This completion mechanism should probably never be used implicitly, but it might still be useful to display a small completion popup in a GUI, or during manual testing on the CLI.
