Aquachain
What is Aquachain?
Aquachain is a distributed computing platform based on proof of work chain technology. Its not a company, and there was no ICO, no pre-mine, no dev fund, no pre-sale, etc. Transactions, once mined, are irreversible and uncensorable. It is not a token platform.
Aquachain is the blockchain, AQUA is the fuel. You need AQUA to create and interact with contracts, store data, and to send transactions (as a tx fee).

Code Review
Lots of work was done to improve the go-ethereum source code in order to create Aquachain. Not much has been documented.
The most obvious changes is our use of scheduled hard forks (HF). In the beginning this allowed some difficulty adjustments and resolve issues that required a hard fork to fix. (HF4)
Less obvious is the gutting that happened between 1.7 and 1.9. Removed LES and Light ethereum protocols, fixing many issues that can be found in ethereum. Reduced memory usage by 50%.
The most innovative change thus far has been HF5, which includes a “version” field attached to each block header. This allows the AQUA network to change algorithms for future scheduled hard forks. Now, we use a cryptographic hash function named Argon2id (in the Argon2 family). This makes it possible to use a normal CPU to mine AQUA. This header field is not stored in the database, or transfered p2p. It is calculated using the map below.
New features include RPC security flag: -allowip, console ‘send’, ‘balance()’, ‘pending()’, and ‘admin.richlist()’ and ‘admin.supply()’
As the network matures, hard forks have happened less frequently.
Hard forks that are activated currently are HF1 through HF7.
HF8 and HF9 are activated on testnet (and testnet2).
// AquachainHF is the map of hard forks (mainnet)
AquachainHF = ForkMap{
1: big.NewInt(3600), // HF1 (difficulty algo) increase min difficulty to the next multiple of 2048
2: big.NewInt(7200), // HF2 (difficulty algo) use simple difficulty algo (240 seconds)
3: big.NewInt(13026), // HF3 (difficulty) increase min difficulty for anticipation of gpu mining
4: big.NewInt(21800), // HF4 (supply) remove ethereum genesis allocation
5: big.NewInt(22800), // HF5 (POW) argonated (algo #2) (argon2id)
6: big.NewInt(36000), // HF6 (difficulty algo) divisor increase
7: big.NewInt(36050), // HF7 (EIP 155, 158)
}
