With biggest respect for Bitcoin, BitcoinCash, Zilliqa, and Thunderella.

## TL;DR
- Zilliqa is sharding + smart contract + GPU PoW for shard determination
- All permissionless blockchains are spatrated into three properties: `Type of Sybil Attack Mitigation Cost + Data Structure for History Consensus + Scalability Trade-off`
- $BTCSH is just a clone of Zilliqa because...
  - Replace hash algorithm with DIY hash algorithm and DIY ASIC
  - Turn off Gas module, and mitigate DoS by your own construction
  - Less eager to Smart Contract ecosystem

## Spec
- Type: PoW-permissionless pBFT(sharding, 33%halting, 66%reverting)
- Purpose: Store of Value, General Merchandising, Censorship-resist, and no 2nd layer 
- PoW algo: Original dedicated FPGA ASIC (All miners must buy it)
- Blocktime,size: Same as Zilliqa
- Finite Coin Supply (21000000)
- Immutable (no revert by community)
- No ICO in order to be commodity
- Smart Contract: Finite State Machine only, Formal Verifiable, Account Model, and Script based(is it possible?)
- Remove Gas from Zilliqa

## Insight
- SoV, but seamless transaction experience
- Useful but have network layer censorship-resistance
- No big block: Nonce-added chunked final block propagation
- No adversarial shortsell: Smart Contract abandoned design
- Linear scalability
- BTC flavored incentive to utilize on shop (SoV viral)
- Maybe Stronger than usual PoW's selfish mining (No pool needed coz PoW is less frequent) ... Need clarification
- Shard robustness: 33%halting, but 66%reverting. Chain halting condition is BTC equal, Chain crashing condition is almost impossible ... need clarification

## Upside
- This coin is Pure commodity, not a security like ICO-ed Store of Value
- No Gas for Tx
- No channel opening: Seamless experience and good for referal like BCH
- No trolling from bigger, same hash-algo chain like Monacoin (20++ height reorg 51% attack there was)
- Censorship-resistance is provided not like BCH the Big Block
- No [Short sell and 51% Attack](https://ethresear.ch/t/adversarial-shortsell-probability-sum-dapps-price-sum-eth-price/1687) like commodity machine PoW Smart Contract chain

## Downside
- BTC, BCH has security/channel network effect
- Way bit complicated
- Protocol is not formally verified
- Reorg is complicated as per Zilliqa
- DoS mitigation for no Gas custom needed
- Is the FinalBlock(TxBlock) getting to be giga block?

## Lastly
- You might say "Nah, Bitcoin has strong network effect".
- The value of this protocol is innately it is "commodity".
  - Is the Litecoin no value? Not.
- Commodity doesn't promise anything thus it is security.
- Gold and Silver there are. Each of them have different beauty and usage. Commodity discovery engineering is not "winner takes all". Just share the new natural resources/asset-class with others.
