# Teste Aprendendo Conceitos de Blockchain
Made from scratch, generic propose, production ready blockchain for uses like office files, criptocurrency
Build using TDD
**Test Coverage**
## Features
- [v] Server
- [X] Creating blocks
- [X] Block
- [X] Block's hash
- [x] Test
- [X] Transaction
- [x] Transaction list Hash
- [x] Test
- [x] Key
- [x] Transport => tcp, udp,
- [X] Local transport layer
- [X] Crypto Keypairs and signature
- [X] Block Signing
- [X] Blockchain struct
- [X] Storage (memory storage)
- [X] Transaction Encoding/Decoding
- [X] Block Encoding/Decoding
## Todos
Improvements and fixes that can be implemented
- [ ] Add a database or a better storage method to store transactions and block data
## Types
- Hash
```go
type Hash [32]uint8
type Address [20]uint8
```
### Mistakes to remember
On the struct Transaction on Signing the transaction the object was missing the value of the transaction's `Signature`, returnning a null value
```go
func TestSignTransaction(t *testing.T) {
privateKey := crypto.GeneratePrivateKey()
tx := &Transaction{
Data: []byte("foo bar baz"),
}
assert.Nil(t, tx.Sign(privateKey))
assert.NotNil(t, tx.Signature) // FAIL
}
```
Beacuse of the method signatue (tx T) insted of (tx *T), the object was missing the reference
**`old`** :
```go
func (tx Transaction) Sign(privKey crypto.PrivateKey) error {
```
**`fixed`**:
```go
func (tx *Transaction) Sign(privKey crypto.PrivateKey) error {
```
