Performing various Blockchain protocols data integration to the platform

MPC ( A.K.A multiparty computation) Key manangement research - Based on the Existing provider's technology. - Savior, Zengo, Unbound tech, curve etc. Hardfork effect research on Hot wallet operation. - Cosmos (a.k.a Atom) - Bitcoin : replay attack - Cardano - SteemNetwork congestion research to resolve efficient & cheaper transaction broadcasting - Ethereum Solidity code auditing for Economic side. ( not Tech)

Blockchain integration for Asset listing & transferring - Klaytn : Ethereum-EVM equivalance blockchain protocol link : https://github.com/klaytn - Implement internal wallet system based on the Web3 library with Golang ( Key generation, Sign Transaction, Broadcasting Transaction) - Implement key management system for fee delegation with Node.js .( Key generation, Sign Transaction) - Result : Total daily Fee usuage amount reduced more than 40%. Provide more accurate assets data to Accounting team. - Internal tooling for real time blockchain asset movement catcher.- Cosmos : Tendermint consensus engine based Blockchain project. link : https://github.com/cosmos/gaia - Node set up for 24/7 Operation. - Implement Wallet based on the cosmos-sdk. ( Key generation, Sign Transaction, Broadcasting Transaction) - Implement dedicated transaction decoder for amino typed transaction. - Internal tooling for real time blockchain asset movement catcher.- Hive : Blockchain project hard-forked from the Steem. link: https://hive.io/ - Node set up for 24/7 Operation. - Key set up process develop. - Symbol : Blockchain project based on the NEM foundation. link : https://github.com/symbol/ - Implement internal wallet system with Typescript ( Key generation, Sign Transaction, Broadcasting Transaction) - Internal tooling for real time blockchain asset movement catcher.- Proton : Blockchain project forked from EOSIO. Treating Hardfork process - Cardano ( Byron to Shelly) - Steem. - Cosmos - ZilliqaBuild Internal node Build system through Docker. - Result 1. Reduced build time to make asset integration time. 2. Unified running environment based on the Docker that makes find out what is the fault easier.[Pilot] Build node logging aggregation/integration system based on the fluentd.

- Deeply research about distributed computation algorithm - Byzantine general's problem. - Paxos algorithm - PBFT - Tendermint - Stellar consensus protocol. ( a.k.a SCP). - Based on the research , Participated in designing consensus algorithm Called ISSAC. - ISSAC is the based on the PBFT, SCP. - It was first attempt to create consensus algorithm in the South Korea. - ISSAC protocol explained : https://github.com/bosnet/docs/blob/master/ISAAC-draft.md- Implement transaction builder SDK. - Please see : https://github.com/johndoe0x?tab=repositories - Java based - Payment focused. - Translate various consensus algorithm academic journals to Korean Please see this link : https://github.com/bosnet/papers- Developing developer's blog. Please see this link : https://github.com/bosnet/docsAt the time being PBFT based cryptocurreny project hadn't existed in the South Korea. So This attempt looks like huge step to accelerate blockchain project overall in the South Korea's crypto currency industry field.
