Introductory presentation about Tomochain: an efficient blockchain infrastructure for d-apps, token issuance and integration

1. Tomochain
Building the Blockchain Infrastructure for the Internet of Value

2. Introduction
Long Vuong
CEO of Tomochain PTE. LTD. since 2016;
Former project lead at NEM, 2014;
Son Nguyen
CTO of Tomochain PTE. LTD.
Co-founder of Vietnam Blockchain Developers group;

3. Problem statement
High transaction fee
Slow confirmation
Network congestion

4. Problem statement - Examples
- https://devery.io/ : product verification protocol
- https://www.wetrust.io/ : decentralized platform for financial products
- https://tomoapp.com/ : token based Q&A social network

8. Solutions to scalability
- Payment channel (Raiden, Lighting network)
- Sharding (Zilliqa)
- Proof of Stake
- Side-chain (Plasma framework)
- On-chain scaling with POA and Master-node architecture (Dash, Bitshare,
EOS)

9. Tomochain
8/2018: Tomochain 1.0 (PoA Consensus)
2019: Tomochain 2.0 (PoS - Masternodes)
Using Geth code-based (Ethereum)

10. Tomochain 1.0
Using Clique PoA Protocol: https://github.com/ethereum/EIPs/issues/225
We change:
● Block Time
● Gas Price & Block Gas Limit
● Reward
● Concensus mechanism
Testnet: https://stats.tomocoin.io

11. Tomochain 2.0
Move from PoA to Proof Of Stake Consensus - Masternodes
● Anyone deposits TMC to Smart Contract to vote for Masternodes
● Users who vote for masternodes can receive the reward

12. Built-in governance d-app
Vote for Hard-Fork
Vote for Master-nodes
Vote for economic policies

13. Vote for
Masternodes
1. Send TMC/Vote for 0x2b22...
2. 0x2b22… becomes a
masternode
3. 0x2b22 signs to confirm a block

14. Reward
1. At RewardPoint, using Reward
Algorithm, masternodes will
calculate to make Reward
Transactions in Reward Smart
Contract
2. Reward will be sent to Tomo
Masternode Smart Contract
3. Users who vote for
masternodes can get Reward
from the contract.

15. Key services
Built-in decentralized exchange protocol using TMC
Cross-chain token transfer using smart-contracts using TMC
ICO platform to reward coin holders

16. Economics of TMC
Using coins to govern the network
Using coins in all infrastructure services

17. General approach
- Being an efficient blockchain infrastructure layer for d-apps, token issuance
and token integration
- Being a contributor to the Ethereum ecosystem
- Being an evangelist for tokenization and moving financial values on chain

18. Demo
Cross-chain token transfer using smart-contracts
