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.
Zcoin (XZC) is a cryptocurrency focused on privacy and decentralization. It is the first coin to implement the Zerocoin protocol that enables financial privacy through the power of zero knowledge proofs with a focus on making privacy easy to use. It is also set to be the first to release MTP an ASIC resistant, anti-botnet proof of work algorithm that remains lightweight to verify to ensure fair distribution of coins and decentralized security. Zcoin is an open source decentralized cryptocurrency that focuses on achieving privacy and anonymity for its users while transacting. To achieve this privacy and anonymity, Zcoin uses zero-knowledge proofs via Zerocoin protocol which is one of the most cited cryptography papers at this point in time. In other words, when you transact using Bitcoin or Ethereum or something similar, your transaction history is always linked to your coins by default which makes you vulnerable. That, because all it takes is one link to your personal information or IP to find out the origin of the coins.However, if you transact using Zcoin’s Zerocoin feature, none of your transaction histories is linked to the actual coins and only the receiver and sender know that you have actually exchanged funds. Zerocoin is a cryptocurrency proposed by Johns Hopkins University professor Matthew D. Green and graduate students Ian Miers and Christina Garman as an extension to the Bitcoin protocol that would add true cryptographic anonymity to Bitcoin transactions. Zerocoin was first implemented into a fully functional cryptocurrency released to the public by Poramin Insom, as Zcoin who is also the lead developer, in September 2016. At the initial stage, Zcoin uses the Lyra2z algorithm for proof of work, then they will transition to a Merkle Tree proof of work algorithm, known as MTP. MTP is a unique memory hard algorithm that aims to solve several problems. Memory hard algorithms help prevent the development of ASICs which lead to centralized mining farms. Memory hard algorithms also prevent the use of botnets infecting computers for mining purposes. If a botnet was using up multiple gigs of memory, you’d be likely to notice something is wrong. “The basic concept is that it should establish the same price/cost for a single computation unit on all platforms meaning that there is no single device that should gain a significant advantage over another for the same price hence promoting egalitarian computing.
