70491aea8c Utils: Moving_average: use int64 for total 2017-02-24 16:20:59 +01:00

fc53f3b233 Switch to Base58. 
Base48 was fun but... hell yeah... let's stay standard.

Public encoding of hash:

```
  Block:      "B..." (len: 51)
  Operation:  "o..." (len: 51)
  Protocol:   "P..." (len: 51)

  Ed25519:    "tz1.." (len: 36)
  Contract:   "TZ1.." (len: 36)

  NetworkdId: "id.." (len: 30)
```

Other internal prefixes (in the RPC):

```
  Hash of Michelson's expression: "expr..." (len: 54)

  Ed25519 public key: "edpk..." (len: 54)
  Ed25519 secret key: "edsk..." (len: 98)
  Ed25519 signature:  "edsig.." (len: 99)

  Hash of a random seed nonce: "nce...." (len: 53)
  Random seed:                 "rng...." (len: 53)
```

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

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.
