Title: [ANN][AMTC] 🏺AmberTime💎🕰️: 1st 🎓Education🎓 + ✈️Travel✈️+ ⛓️Blockchain⛓️ Post by: ambertime on March 20, 2018, 09:37:02 AM [ANN][AMTC] 🏺AmberTime💎🕰️: 1st 🎓Education🎓 + ✈️Travel✈️+ ⛓️Blockchain⛓️ Platform HISTORY OF AMBERTIME If you’ve ever carefully looked into Amber, you would’ve noticed that there’s a secret of time inside. 3 million years of humanity, how many lives hollowed and cultures vanished? 4.6 billion years of Earth’s rotation, how many species buried to ground and oasis turned desert? Time never stands still, we find ourselves through the stream of time. Did we create time, or did time create us. The mission of the living is to pass on the genetics through reproduction, and the mission of humans is to carry on human civilisation through language and texts. But what is civilisation? Is it countries, tribes, formalities, practices and things? Religion, philosophy, law, technology and art? Civilisation may be each actual, lively, dynamic individual - every person is a medium of civilisation. Did we create civilisation, or did civilisation create us. AmberTime originated from contemplation of the questions about time and civilisation. These questions are rather significant for the modern minds and civilisation. What does civilization means for us? How do we create our own time? It might be an inspiration from one immersed reading, it might be one hiking in the wilderness, it might be one enthusiast’s passion project, it might be a certificate for a profession. It might be a college assignment, it might be an adventure to circumnavigate. It might be an emblem from an educational institution, it might be one remarkable event of life. AmberTime is created for every person’s precious moments in life, every bit is securely, factually and permanently recorded by the use of blockchain technology. Amber is created for everyone to come closer to our civilisation, through the media of civilisation - the interesting, cultivated, passionate and profound individuals, join an open source, boundless world university and turn time into priceless Ambers. FIRST EDUCATION + TRAVEL + BLOCKCHAIN PLATFORM As an open platform of blockchain “certified history”, AmberTime blockchain application class products are open to schools of all levels, educational and training institutions, examinations and assessment institutions, qualification certification institutions, travel organizations, and travel product platforms around the world. Not only that it means the way people receive their education and the way they travel will go through a revolutionary change, it also means people’s life-long educational history and travel footprints will be permanently and safely stored as a very important data capital. OUR VISION AmberTime's vision is to become the world's most recognized and prestigious education institution with its time-flow inspired, open source and borderless philosophy grounded on blockchain innovation. OUR MISSION To drive the intersection of both education and tourism by cultivating and nurturing talent with multi-sectoral ability, wide range of interests, international perspective and a heart to contribute to the society. To create a top-ranking global university based on open source and borderless principles by way of establishing a thematic institute with various types of institutions, organizations, enterprises and individuals who share the same values and educational philosophy, and together develop curriculum contents, design travel projects and make them more accessible and fulfilling to the youth. To use the flow of time as a means of recording behaviour, academic achievements, merit awards, travel experiences and certifications can become one's irreplicable and tamper proof assets, condensing into their own exclusive and unique "Amber". PROBLEM Fake IDs, diplomas, and certificates in the black market Difficulty in verifying claims of achievement and accreditations Traceable personal activities in open ledgers High-trust requirement between mutually foreign parties in commercial engagements Slow and resource intensive transaction processing SOLUTION Grant cryptographically secure electronic credentials in blockchain Support authentic claims of merit through digital signature and time verification logged in blockchain Indiscernible encrypted transactions visible only by authorized parties published in blockchain Decentralized trust network ensuring transaction governance and execution of escrows in the form of blockchain More efficient Proof-of-Authority / Proof-of-Time blockchain consensus algorithm instead of Proof-of-Work implementation USE CASES EDUCATION Validate educational achievements by auditing student credentials recorded on the blockchain. EXPERIENCE Log trips, tours and events joined on the blockchain upon booking or checking in. E-COMMERCE List, hunt, shop for goods and services directly from the blockchain wallet. FEATURES TIME BASED VALIDATION Merchants can specify a maturity period for services, such that completion of the purchase can only be done after the maturity period. AUTO ESCROW OF PAYMENTS Payments can be automatically place in escrow, requiring the consent of both the buyer and the service provider for the payment to go through. TIME LIMITED AUTHORIZATION Users can choose to selectively grant authorization to view their information on a time-based expiry. When the expiration date has passed, the authorization will automatically be revoked. INTEGRATION OF E-COMMERCE DIRECTLY INTO THE WALLET Amber's Smart Wallet will allow the user to browse services and make payments and other transactions within the network. PROOF OF AUTHORITY CONSENSUS Transactions are approved through a consensus of nodes that are authorized as approvers. Approvers are incentivized to uphold transaction validity because their reputation is at stake. ZERO TRANSACTION FEE Transactions on the Amber network are not subject to transaction fee. Instead, wallets will be limited to a certain number of transactions over a given period. Wallets with more stake in the system will be allowed to make more transactions. REAL-TIME Fast transaction confirmation and account settlement which doesn't take 3 days, or even 10 minutes. IMMUTABLE Proof-of-Integrity binded to the AMTC blockchain to ensure immutability and settlement finality. PRIVACY Configurable degrees of privacy, from transparent. publicly auditable to private only. SECURE Every individual transaction in AMTC is digitally signed unlike normal databases.

Thank you for the vote of confidence! 👍 While conceptually the idea of quantifying knowledge in terms of amalgamation of formal / informal studies, apprenticeship and experiences has existed, its only until recently the right technology has arrived to allow it to come to fruition through the use of blockchain. Through the community's support, we hope to bring the vision of open learning and merit-based credentialization to drive a generational shift of information-based academics, to a more wisdom-based learning.

How could it be used to secure the application in education and travel business?
Title: Re: [ANN][AMTC] 🏺AmberTime💎🕰️: 1st 🎓Education🎓 + ✈️Travel✈️+ ⛓️Blockchain⛓️ Post by: ambertime on April 02, 2018, 06:53:57 AM What does it mean by the POA mechanism? How could it be used to secure the application in education and travel business? Thank you Lantern_NPT for your question 🙋🙋 AmberTime will be a Consortium Chain - one difference from the public chain is that the owners / operators of the nodes will not be anonymous. The ecosystem itself however will be open to the public to participate and access. PoA stands for "Proof-of-Authority" - a sort of word-play on the other mechanisms such as "Proof-of-Work" (PoW) and "Proof-of-Stake" (PoS). Proof-of-Authority is the consensus mechanism in which the nodes validating blocks are the ones explicitly allowed to do so. PoA is a modified form of PoS where instead of stake with the monetary value, a validator’s identity performs the role of stake in the form of reputation. In this context, identity means the correspondence between a validator’s personal identification on the platform with officially issued documentation for the same person, organization or institution, to ascertain that a validator is exactly who it represents to be. This is a way to preserve the staking concept, with scarcity and measurability of stake, while ensuring that all who place that stake value it similarly, regardless of other circumstances. Even if one steals a license and somehow becomes a validator pretending to be someone else, the fact that staking is public will expose a nefarious actor. A single actor with a hacked authority does not have the capacity to overwhelm the network and revert all transactions. Therefore, requiring validators to have an approver public license makes identity impossible to conceal, while a concerned party can easily cross-verify identity in publicly available open domain. With on-chain governance making it simple to oust a non-conforming validator, losing a validator’s role eligibility is public and published in the network. With their real names at stake, validators are unlikely to act nefariously to threaten their own social standing in the real world and virtual community of the blockchain network. In AmberTime's context, this means that there will be "Authority" nodes within the chain are preregistered and verified entities, and each of them is an organization with a proud reputation to protect, such as universities, government agencies, law firms, businesses, travel agencies etc. Each transaction in AmberTime would be signed by a randomly selected and voted upon by set of Authority nodes. Since the organization's reputation is at stake, the risk of a malicious signer is reduced to minimum, and in such an unlikely event, an erring signer would be voted out by the network automatically, and can only be reinstated manually by AmberTime after thorough investigation. Hope this helps! Added info: Known successful examples of PoA implementations are Kovan and Rinkeby, the two Ethereum testnets named after metro train stations, which were introduced as new blockchain based on Ethereum protocol with Proof of Authority consensus. Spam attack on the original Ropsten testnet was the reason to create a new public test network. Based on data gathered on both testnets, PoA Networks provides inexpensive consensus to secure the network. Users can run Ethereum programs on Kovan and Rinkeby and spend less money on transaction fees which also translates to the network's security will also be cheaper to maintain.

I'm ok with the security issues in respect of the POA algorithm. What about the data structure ? what would be the advantage of using blockchain technique vs using a database storage, i.e. a piece of record or notary ? If i'm one of the authorities to write data to the blockchain main network, when i need to send certain record to the user upon request, does the traditional data structure and DBMS still applicable or even more efficient in data sorting and accessing for the blockchain main network? I remember that all data is stored in the blockchain main network if i'm correct.

Hope this explanation makes it clearer 💎💎💎 ;D Title: Re: [ANN][AMTC] 🏺AmberTime💎🕰️: 1st 🎓Education🎓 + ✈️Travel✈️+ ⛓️Blockchain⛓️ Post by: melanie19283 on April 11, 2018, 09:26:13 AM I’ve read your project and read the comments of the people who care ‘bout the project.

Having said this, today the most dominant blockchain consensus convention referred to us Proof of Work (PoW), have somewhat of a contradictory constraint: each node in the network must process each and every transaction that passes through the network. This is an also a classical trait of the decentralized nature of blockchain which implies that each and every node on the system processes each activity and keeps up a duplicate of the whole state of the network. While a decentralized PoW consensus mechanism used by popular blockchain networks such as Bitcoin and Ethereum, offers some critical benefits, such as fault tolerance, a strong guarantee of security, political neutrality, and authenticity - it comes at the cost of scalability. The number of transactions the blockchain network can process will be unable to surpass that of a single node that is contributing to the network. In effect, the blockchain essentially becomes more inefficient as more nodes are added to its network which is supposed to increase the capability of the network overall but instead have the inverse effect because of the inter-node latency required to transmit and maintain a copy of the network’s current state in every node which logarithmic-ally increases in complexity with every additional node. To illustrate this further, we can make a comparison to a traditional database system to which the solution to scalability is to add more servers by scaling vertically or horizontally in order to manage handle more transactions. In the decentralized blockchain where every node needs to process and validate every transaction, it would require additional compute to every node for the network to get faster. Having no feasible way to coordinate or control over every publicly joined node which are owned by many numerous individuals of diverse interests and motivations in the network resulting in no direct mechanisms to scale vertically or horizontally. In other words, as the size of the blockchain network increases, the requirements for storage, bandwidth, and compute power required by fully participating nodes in the network increases. At some point, it becomes unwieldy enough that it’s only feasible for a few high powered nodes to process a block of transactions leading to the risk of centralization in the network. As a result, all public blockchain employing Proof of Work consensus protocols in such a decentralized manner make the compromise between transaction throughput and degree of centralization, choosing to sacrifice the speed of processing operation resulting in a degraded experience for users executing valid transactions in order to retain the benefits of a decentralized network. In order to scale, the blockchain protocol must work out a mechanism to control the number of participating nodes needed to validate each transaction, without losing the network’s trust that each transaction is valid.

With regards to data structure, we envision to store only the raw data / meta data surrounding a certified transaction in the blockchain. As an example, information found in a training certificate like name, course name, date completed, etc. are recorded in the blockchain to validate a person's credentials and potentially allow dynamic generation of an image forming an e-certificate for printing purposes. Good questions - lets keep the discussion going! :D :D :D Title: Re: [ANN][AMTC] 🏺AmberTime💎🕰️: 1st 🎓Education🎓 + ✈️Travel✈️+ ⛓️Blockchain⛓️ Post by: Lantern_NPT on April 13, 2018, 07:23:28 AM Dear Ambertime support,
I'm so glad for the ongoing discussion, which philosophically i can't agree more on the scalability issue. Technically, I'm so eager to see that your team can nail the whole project and come up with a product that we can enjoy. One of my friends even told me that blockchain is the future of big data storage. It's a vivid approach to thrust the value of information flow where traditionally, people either needs to pay or sacrifice some privacy to have a piece of critical information safely transferred and stored in time and space. Right now, i cannot imagine how ordinary people can benefit from this project. Many people don't have much knowledge over such visionary project. We need more brave and innovative people, that 1% open enough to understand, use and then influence more people to accept all those new notations and concepts. You guys have done a great job, but i'm hoping to see more achievement to come from you. Will come up with more perspectives when i have time. Let's keep the rock rollling. sounds pretty neat.

Hello Lantern_NPT 😎😎😎 We are currently aiming a 10 second ⌛ block confirmation rate, the blocksize of which we have yet to finalize but will be determined during alpha phase when implemented on test net. In terms of mining and validation difficulty, it will be kept at a low threshold since all the ⛏️⛏️miners⛏️⛏️ in POA are pre-selected and trusted nodes.
