formally an informal introduction to blockchain author darren mccarley date ۳ ۱۳ ۲ ۱۸ https www.linkedin.com in darrenmccarley disclaimer this is not a bitcoin introduction. this is a high level introduction to blockchain technology. however we should acknowledge that satoshi nakamoto pseudonym and his their creation bitcoin popularized blockchain technology. there are currently arguments that bitcoin was not the first blockchain. today there are various flavors of blockchain. this paper attempts to generalize blockchain with samples in some of those flavors. additional research prototyping and due diligence should be exercised before making any long term decisions. lastly it is the opinion of the author no single blockchain solution will fulfill all needs. as many of the blockchain technologies are paradigm specific one should educate themselves on when and how to implement a blockchain solution. perhaps more importantly when not to implement a solution. a brief history of blockchain on october ۳۱ ۲ ۸ satoshi nakamoto released the bitcoin white paper outlining a purely peer to peer electronic cash digital asset transfer system. this is the first popular implementation of blockchain and is attributed as birthing today’s blockchain industry. since then additional blockchains have been popularized ethereum various hyperledger project solutions as well as numerous others including blockchain like solutions such as guardtime’s ksi products what is blockchain blockchain is a system comprised of.. transactions immutable ledgers decentralized peers encryption processes consensus mechanisms optional smart contracts let’s explore these concepts transactions as with enterprise transactions today blockchain is a historical archive of decisions and actions taken proof of history provides provenance demo https anders.com blockchain blockchain.html notable transaction use cases land registration – replacing requirements for research of deeds sweden land registration personal identification – replacement of birth death certificates driver’s licenses social security cards estonia transportation – bills of lading tracking certificates of origin international forms maersk ibm banking – document storage increased back office efficiencies ubs russia’s sberbank manufacturing – cradle to grave documentation for any assembly or sub assembly food distribution – providing location lot harvest date supermarkets can pin point problematic food walmart audits – due to the decentralized and immutable nature of blockchain audits will fundamentally change. immutable as with existing databases blockchain retains data via transactions the difference is that once written to the chain the blocks can be changed but it is extremely difficult to do so. requiring rework on all subsequent blocks and consensus of each. the transaction is immutable or indelible in dba terms blockchains are write and read only like a ledger written in ink an error would be be resolved with another entry decentralized peers rather than the centralized hub and spoke type of network blockchain is a decentralized peer to peer network. where each node has a copy of the ledger. legacy network blockchain network centralized db distributed ledgers encryption standard encryption practices some blockchains allow for byoe bring your own encryption only as good as the next hardware innovation all blocks are encrypted some blockchains are public some are private public blockchains are still encrypted but are viewable to the public e.g. https www.blocktrail.com btc private blockchains employ user rights for visibility e.g. customer – writes and views all data auditors – view all transactions supplier a – writes and views partner a data supplier b – writes and views partner b data consensus ensures that the next block in a blockchain is the one and only version of the truth keeps powerful adversaries from derailing the system and successfully forking the chain many consensus mechanisms each with pros and cons consensus mechanism proof of work proof of state proof of elapsed time proof of activity proof of burn proof of capacity proof of importance and others…. smart contracts computer code provides business logic layer prior to block submission blockchain smart contracts language bitcoin no ethereum yes solidity

ledger ensuring appropriate visibility transactions are secure authenticated verifiable business terms embedded in transaction database executed with transactions all parties agree to network verified
