The blockchain is an incorruptible digital ledger of economic transactions that can be programmed to record not just financial transactions but virtually everything of value (by [Don Tapscott](https://www.linkedin.com/pulse/whats-next-generation-internet-surprise-its-all-don-tapscott)).

## Frequently Asked Questions (F.A.Q.s) & Answers
|
||
|
||
**Q: What's a Blockchain?**
|
||
|
||
A: A blockchain is a distributed database with a list (that is, chain) of records (that is, blocks) linked and secured by
|
||
digital fingerprints (that is, crypto hashes).
|
||
Example from [`blockchain.rb`](https://github.com/openblockchains/awesome-blockchains/blob/master/blockchain.rb/blockchain.rb):
|
||
```ruby
|
||
[#<Block:0x1eed2a0
|
||
@timestamp = 1637-09-15 20:52:38,
|
||
@data = "Genesis",
|
||
@previous_hash = "0000000000000000000000000000000000000000000000000000000000000000",
|
||
@hash = "edbd4e11e69bc399a9ccd8faaea44fb27410fe8e3023bb9462450a0a9c4caa1b">,
|
||
#<Block:0x1eec9a0
|
||
@timestamp = 1637-09-15 21:02:38,
|
||
@data = "Transaction Data...",
|
||
@previous_hash = "edbd4e11e69bc399a9ccd8faaea44fb27410fe8e3023bb9462450a0a9c4caa1b",
|
||
@hash = "eb8ecbf6d5870763ae246e37539d82e37052cb32f88bb8c59971f9978e437743">,
|
||
#<Block:0x1eec838
|
||
@timestamp = 1637-09-15 21:12:38,
|
||
@data = "Transaction Data......",
|
||
@previous_hash = "eb8ecbf6d5870763ae246e37539d82e37052cb32f88bb8c59971f9978e437743",
|
||
@hash = "be50017ee4bbcb33844b3dc2b7c4e476d46569b5df5762d14ceba9355f0a85f4">,
|
||
...
|
||
```
|
||
|
||
|
||
**Q: What's a Hash? What's a (One-Way) Crypto(graphic) Hash Digest Checksum**?
|
||
|
||
A: A hash e.g. `eb8ecbf6d5870763ae246e37539d82e37052cb32f88bb8c59971f9978e437743`
|
||
is a small digest checksum calculated
|
||
with a one-way crypto(graphic) hash digest checksum function
|
||
e.g. SHA256 (Secure Hash Algorithm 256 Bits)
|
||
from the data. Example from [`blockchain.rb`](blockchain.rb/blockchain.rb):
|
||
|
||
```ruby
|
||
def calc_hash
|
||
sha = Digest::SHA256.new
|
||
sha.update( @timestamp.to_s + @previous_hash + @data )
|
||
sha.hexdigest ## returns "eb8ecbf6d5870763ae246e37539d82e37052cb32f88bb8c59971f9978e437743"
|
||
end
|
||
```
|
||
|
||
A blockchain uses
|
||
|
||
- the block timestamp (e.g. `1637-09-15 20:52:38`) and
|
||
- the hash from the previous block (e.g. `edbd4e11e69bc399a9ccd8faaea44fb27410fe8e3023bb9462450a0a9c4caa1b`) and finally
|
||
- the block data (e.g. `Transaction Data...`)
|
||
|
||
to calculate the new hash digest checksum, that is, the hash
|
||
e.g. `be50017ee4bbcb33844b3dc2b7c4e476d46569b5df5762d14ceba9355f0a85f4`.
|
||
|
||
**Q: What's a Merkle Tree?**
|
||
|
||
A: A Merkle tree is a hash tree named after Ralph Merkle who patented the concept in 1979
|
||
(the patent expired in 2002). A hash tree is a generalization of hash lists or hash chains where every leaf node (in the tree) is labelled with a data block and every non-leaf node (in the tree)
|
||
is labelled with the crypto(graphic) hash of the labels of its child nodes. For more see the [Merkle tree](https://en.wikipedia.org/wiki/Merkle_tree) Wikipedia Article.
|
||
|
||
Note: By adding crypto(graphic) hash functions you can "merkelize" any data structure.
|
||
|
||
**Q: What's a Merkelized DAG (Directed Acyclic Graph)?**
|
||
|
||
A: It's a blockchain secured by crypto(graphic) hashes that uses a directed acyclic graph data structure (instead of linear "classic" linked list).
|
||
|
||
Note: Git uses merkelized dag (directed acyclic graph)s for its blockchains.
|
||
|
||
**Q: Is the Git Repo a Blockchain?**
|
||
|
||
A: Yes, every branch in the git repo is a blockchain.
|
||
The "classic" Satoshi-blockchain is like a git repo with a single master branch (only).
