Agenda

1. 기업용블록체인개요

2. Oracle Blockchain Platform 소개

3. Demo

비허가 (개방형)허가형

• 허가된멤버만이네트워크에참여

• 예: 제조업체및공급업체,화물운송업체및브로커네트워크등

• 보다안전하고향상된관리 – 사전에알려진참가자

• 기업형으로적합함

• 인터넷에있는누구나가입하여원장정보에액세스할수있음

• 예: Bitcoin, Ethereum, 등

• 덜안전하고빈약한관리 -사전에알려지지않은참가자

오라클은 Permissioned 엔터프라이즈블록체인플랫폼제공

블록체인의두가지유형

보안강화

비용감소

블록체인네트워크의확인된데이터를기반으로더많은거래수행, 보안강화,비용절감등을통해컨소시엄구성원간의투명성을제공한다

더많은트랜잭션

기업용블록체인이란?

Applications(Client SDK)

Validating Nodes/ Peers

Distributed Ledger (Single Version of Truth)

Smart Contract (aka Chaincode)

Membership Service

Ordering Service

Identity Management (for member enrollment)

Fault Tolerant Event Hub (for ordering event mgmt.)

Container Lifecycle Management (for system and chaincode containers)

Configuration & Monitoring Tools

Autonomous Recovery(when components fail)

Managed Patching & Upgrades

Elastic scaling on demand

Multi-datacenter DR(with backup of ledger and config info)

Oracle Blockchain Platform

• OS 설치

• cURL install

• Docker / Docker Compose 설치

• Go, Node.JS설치

• Python설치

• Curl로 Hyperledger 설치

• Crypto-config.yml을참조해서 Key file 생성

• cryptogen generate --config=./crypto-config.yaml

• Genesis block 생성

• Crypto-config.yml을참조해서 Key file 생성

• configtxgen -profile OneOrgOrdererGenesis -outputBlock ./config/genesis.block

• Create a Channel Configuration Transaction

• ../bin/configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org1MSPanchors.tx -channelID $CHANNEL_NAME -asOrg Org1MSP

• Start the network• docker-compose -f docker-compose-cli.yaml up -d

1 Step

직접 Hyperledger Fabric 설치 Oracle Blockchain Platform

Easy Provisioning

• docker-compose-neworg.yaml 생성• Generate the New Org Crypto Material

• ../../bin/cryptogen generate --config=./org3-crypto.yaml • cd ../ && cp -r crypto-config/ordererOrganizations org3-artifacts/crypto-config/

• Prepare the CLI Environment• Fetch the Configuration

• peer channel fetch config config_block.pb -o orderer.example.com:7050 -c $CHANNEL_NAME --tls --cafile $ORDERER_CA

• Convert the Configuration to JSON and Trim It Down• configtxlator proto_decode --input config_block.pb --type common.Block |

jq .data.data[0].payload.data.config > config.json• Add the Org3 Crypto Material

• jq -s '.[0] * {"channel_group":{"groups":{"Application":{"groups": {"Org3MSP":.[1]}}}}}' config.json ./channel-artifacts/org3.json >modified_config.json

• configtxlator proto_encode --input config.json --type common.Config --output config.pb

• 5 more steps …• Sign and Submit the Config Update

• peer channel signconfigtx -f org3_update_in_envelope.pb • peer channel update -f org3_update_in_envelope.pb -c $CHANNEL_NAME -o

orderer.example.com:7050 --tls --cafile $ORDERER_CA • Configuring Leader Election• Join Org3 to the Channel

• docker-compose -f docker-compose-org3.yaml up -d • peer channel fetch 0 mychannel.block -o orderer.example.com:7050 -c

$CHANNEL_NAME --tls --cafile $ORDERER_CA • peer channel join -b mychannel.block

Hyperledger Fabric 에서구성

• 네트워크, 파트너및트랜잭션관리를위한직관적인관리콘솔

Oracle Blockchain Platform

Org 추가및 Join

• Smart Contract 개발자는블록체인에서비즈니스로직을만들고테스트• 콘솔또는 SDK를통해배포

• 웹서비스 / REST API 또는 SDK를통한테스트

• Application 개발자는배포된 Smart Contract를통해트랜잭션을실행하는최종사용자응용프로그램을개발• Client SDK (Java, node.js)

• Web Services/REST APIs

• 개발자생산성향상

• Rich queries on history DB

• Developer Cloud를 CI / CD 용 DevOps 도구로이용
