Ripio Credit Network (RCN) is a global peer-to-peer credit network based on cosigned smart contracts that facilitates connections between lenders and borrowers across the world, on any currency. It enables people across the globe to access credit, and to provide loans. The RCN token is a typical ERC-20 token. This protocol has the smart contract technology embedded into the Ethereum blockchain which facilitates peer-to-peer lending without the hefty transaction fees that are charged in traditional banking processes. The RCN token functions at the core of the system. The inherent value of the token is directly correlated to the demand for its use in the network. Based in Argentina, Latin America, Ripio was launched at the TechCrunch Disrupt in May 2016. Sebastian Serrano, founder and CEO of the Ripio Credit Network is a technology enthusiast. He along with his team of technology experts, analysts and developers have designed an impressive concept along with the website, whitepaper and its implementation within the last 2 years. The team comprises of David Garcia (SVP & Board Member), Eugenio Cocimano (Data Scientist), Antonio Ceraso (CTO & Lead Blockchain developer) and Agustin Aguilar (Smart Contracts Developer) among many others. Ripio started off with a primary objective - to democratize the digital economy in Latin America, by offering digital payment alternatives within everyone's reach in a region where 65% remain unbanked. The smart contract is an integral part of the underlying technology of the Ripio Credit Network. It is generated by the Wallet Provider and executed when it is matched by the Credit Exchange. This smart contract contains information like the relevant credit terms, borrower obligations, events of default along with the signatures or verifications from all other agents. RCN tokens facilitate interaction with the smart contracts among different agents within the RCN. Every credit flow starts when the Borrower makes a credit request. The Borrower performs the request from its Wallet Provider, which has already integrated into the RCN protocol. Post this, the Borrower waits for an approval before any further action can be performed.
Beam Mimblewimble is a scalable, fungible, and confidential cryptocurrency based on the Mimblewimble implementation. WHY BEAM? Core features include complete control over your privacy, All transactions are private by default, No addresses or other private information are stored on the blockchain, Superior scalability due to compact blockchain size, Opt-in Auditability, Support online and offline transactions, atomic swap, hardware wallets integration. Governance model No premine, No ICO. Backed by Treasury Establishing a non-profit foundation to govern the protocol after Mainnet launch How does it work? Wallets’ owners create new transaction using secure channel either online or offline Both wallets participate in signing the transaction using Schnorr protocol Wallet sends transaction to node Each transaction contains a list of Inputs and Outputs represented by Pedersen Commitments, as well as explicit fees and kernels. Each transaction also contains non-interactive zero knowledge range proof to verify that the output transaction value is positive Transaction is verified by the node Each transaction is verified with respect to the recent blockchain state which is stored as a Merkle Tree. The root hash of the tree is recorded in block header along with a proof of work. In addition, each node periodically creates compacted history to allow ‘fast sync’ of new and existing nodes. Transaction is added to the mining pool A block is mined every minute and is sent back to the node for verification and distribution. Mined blocks containing the new transactions are sent to the known peers A valid block that is extending the longest chain is accepted as a new Tip and propagated further until full consensus is reached. Fast sync When a new node connects to the network for the first time it can request compacted history containing only system state and blockchain headers. There is no need to retrieve the entire transaction history.
