  4. 4. • Users meet at the marketplace • Buyer or seller can start the transaction, introducing amount and address for shipping. • The counterpart is notified on his/her mobile phone and accepts the escrow transaction. • Buyer can ask for instant credit. • Seller pays the PSP fee. • The escrow payment is released automatically 24h after successful delivery. • Pay-out to the seller’s account is executed right away. LemonPay. Designed to facilitate the economic transaction between peers 4
  5. 5. 5 the escrow payment provider that enables marketplace revenue models
  6. 6. Secure escrow based transactions are core to the sharing economy: anonymity, compliance and agile business rules for marketplaces 6 Marketplaces, e-commerce websites and mobile apps must guarantee secure transactions between buyers and sellers. Marketpay covers all your operational cycle which includes: o Pay-in and pay-out transactions and wallet statements. o Agile escrow rules and payments upon delivery. Most countries require a banking license to handle money on behalf of third parties. Marketplaces cannot afford to break legal and regulatory requirements and Marketpay is the perfect partner that allows you to concentrate on your core business.

  9. 9. Blockchains allows an application developer to create a distributed database that can be read by anyone, but can only be written to by consensus. A blockchain is a ledger of records arranged in data batches called blocks that use cryptographic validation to link themselves together. Put simply, each block references and identifies the previous block by a hashing function, forming an unbroken chain, hence the name. 9
  10. 10. The blockchain is the flying car of finance and it has finally arrived 10 Many established enterprises are still waiting for the perfect business justification for investigating blockchain… However, by doing that, they run the risk of missing opportunities and failing to identify the business risk of being slow to adopt a disruptive technology.
  11. 11. Trends & The next big thing 11
  12. 12. For a technology that’s still in its comparative youth, blockchain has become incredibly influential, incredibly quickly. 12 World Economic Forum released a report calling blockchain technology a “mega-trend” that will shape society in the next decade. The WEF predicts that blockchains could store as much as 10 percent of global GDP by 2027.
  13. 13. Blockchain technology, though still in emerging stages, is being considered as biggest disruptive technology in the modern technology ecosystem 13 Technology trigger Peak of inflated expectations Trough of disillusionment Slope of enlightment Plateau of productivity EXPECTATIONS TIME Internet of things Crypto currencies Augmented reality 3D Printing Predictive Analytics Smart robots Quantum computing Autonomous vehicles BLOC KCHA IN Gartner, 2015. Hype Cycle for Emerging Technologies
  14. 14. Blockchain is not going to emerge in industry as a single platform, as was once imagined, but as a series of different blockchain platforms designed for different purposes. 14 https://goo.gl/5133lG Map of decentralized transaction ledgers BTC/XB T ETH XRP Hyperledger # of nodes 6,000 7,000 200 200 access Open Open Permission ed Permissioned blockTime 10m 14s 4s ~1ms smartContracts Script Solidity Codius Go
  15. 15. Marketpay auditLog Given blockchain’s unique ability to audit transmissions and movements through log data, Marketpay reflects every transaction on the decentralized ledger, as a backup and anti-tampering measure. 15
  16. 16. Marketpay auditLog Blockchain will make all kinds of transactions transparent, more reliable, and easier to audit without centralized processing. 16
  17. 17. LemonPay: escrows, while they can be conducted through a central agent, are increasingly being conducted through a smart contract on the Ethereum blockchain controlled by several independent agents. 17 BuyerSeller 3rd party logistics Smart Contract is just a phrase used to describe computer code that can facilitate the exchange of money, content, property, shares, or anything of value.
  18. 18. MarketPay tokens implement basic features in a standard way, so they are instantly compatible with the Ethereum wallet and most of smart contracts. 18 Tokens in Blockchain can represent any fungible tradable good: coins, loyalty points, gold certificates, IOUs, in game items, etc.
  19. 19. Blockchain pros Internet of Value (IoV, Web 4.0), earlier adopters o Past: Web 1.0 (a one-way content distribution net) to Web 2.0 (an interactive social net) and Web 3.0 (where smart applications monitor data and make decisions: Big Data, Data Science, NLProc and IoT). o Future: Web 4.0, IoV: • Blockchain 1.0: a distributed ledger technology enabling the P2P exchange of digital value. • Blockchain 2.0: smart contracts & DApps where the exchange of value of payment is conditional upon a "cryptographic proof" based on the occurrence of an event. Security: backup, immutability. Cost-effective: payin, payout. Openness/Transparency: auditLog & escrow Smart Contract. 19
  20. 20. Blockchain cons Why use a database that takes over 10 minutes to commit a transaction and can store only 80 bytes natively? All market participants, regulators and other stakeholders must all be onboard and involved in order to ensure that the blockchain can make a smooth landing. Blockchain's potential is endless, but the tech isn't mature. It comes with the territory when being earlier adopters: o Yet to come sharding features. o PoW is effective but absurd. => PoS, much better! o Cheap $1M/day on the electric bill to get a txRate of 0.5 tx/s => 25 US$/tx ? o Ethereum Smart Contract bugs > 100 per 1000 lines of code. • industry average bugs is 15-50 • Microsoft released code at 0.5 • 0 defects in 500,000 lines of code for NASA. Cryptocurrency high volatility. Income vs Expenses Analysis: https://goo.gl/rHo7fs 20
  21. 21. Blockchain cons Current Eth SC txFee: 0.0036216 Ether ($0.04) => 6 escrows, 1 US$. Decentralization, no such a dream: o Hard forks imply Blockchain decentralization is not to take very seriously. o Just a bunch of developers are in control of Blockchain behaviour. o The bootstrap nodes are hard-coded. o Oracles in Ethereum are trusted parties embedding data into Blockchain. Complex: development, deployment, and running. Example: o startEscrow(alice, bob, 100) o eth_call([{"from": "0xf28dafbfeb41bf32869c9d498da0d651d0206ed4", "to": "0x27c042342c9ba937214117e11a4970a6145034cb", "value": "100000000000000000000", "gas": "22282", "gasPrice": "20000000000", "nonce": "0x100035", "data": " 0x3ccfe887000000000000000000000000a7e3c7c227c72a60e5a2f9912448fb1c2107 8769000000000000000000000000f28dafbfeb41bf32869c9d498da0d651d0206ed4 "}]) 21
  22. 22. Blockchain cons Forks & upgrades => node outages for 24h or even 48h. Internal SC transactions hard to track. Security: o Private key lost or stolen, worst nightmare. o Cryptography resilience: • Quantum pre-image attacks on SHA-3, https://arxiv.org/abs/1603.09383 o The DAO attack: SC vulnerabilities. o DDOS attack => EIP150 Hardfork. 22
  23. 23. Conclusions So far marketpay.io has developed two Smart Contracts to serve marketplaces pulling our API. One writes the audit log for each wallet change, the other codes a real escrow transaction. Nevertheless, both smart contracts are waiting for incumbent players to innovate: Banking partners to provide at least digital EUR and Service Providers (i.e. shipping) to sign directly as oracles. Experts at a recent technology conference agreed that Blockchain has a bright future, but warned it may be a rocky ride until that future arrives. It's far too early to proclaim any sort of winner in the development of a Blockchain stack. But Ethereum and Hyperledger are defining the right kinds of structure for the Blockchain industry to avoid the pitfalls that might limit its potential. Startup lean projects allow the technology to be prototyped, piloted, and put into production without market-wide consensus as a prerequisite. 23
  24. 24. Interesting use cases (multi-peer) Academic Publishing without Journals: A distributed publication platform build on Ethereum and IPFS/Swarm could incentivize post-publication peer review. Decentralized ISP: Every smartphone user has the possibility of creating a WiFi Hotspot with their phone. Data consumption in exchange of automatic payments. Journalism trust system: a global decentralized unstoppable news source with reputation system for investigative journalist and payment directly to the reporter. Provenance & supply chain: stakeholders query supply-chain records on the blockchain and trace them from raw materials through to finished product. Crowdfunding: raising funds using sales of blockchain based digital assets, that are inherently smart contracts that have properties resembling stocks and bonds. Examples: Augur (5M US$), The DAO, Golem (rent your unused CPU/GPU). Democracy: storing votes forever, creating records that can never be tampered with, elimination of multiple voting by individuals and personal convenience as intrinsic values that can be achieved by employing the Blockchain in voting. 24
  25. 25. Less interesting, just one-peer AuditLog: Use blockchain ledger as a backup or audit system. Database/NoSQL: A cloud computer where programs have their own storage space that can't be modified by anything other than the program itself. Outsourcing of business logic: Expressing business logic as smart contracts. 25 Why multi-peer?: Consider the process of buying a house, a complex transaction involving banks, attorneys, title companies, insurers, regulators, tax agencies and inspectors. They all maintain separate records, and it’s costly to verify and record each step. That’s why the average closing takes roughly 50 days. Blockchain offers a solution: a trusted, immutable digital ledger, visible to all participants, that shows every element of the transaction.
  26. 26. Blockchain as a Service (BaaS) provides a rapid, low- cost, low-risk, and fast-deployment platform for organizations to catch the wave of next decade technology, Blockchain. 26 My marketplace to become decentralized Blockchain enabling the sharing economy BaaS
