The Peercoin network activated in 2012 and is one of the first cryptocurrencies to ever be released. It is responsible for inventing proof-of-stake consensus, which makes it the first efficient and sustainable public blockchain technology. Peercoin was inspired by bitcoin, and it shares much of the source code and technical implementation of bitcoin. The Peercoin source code is distributed under the MIT/X11 software license. Unlike bitcoin, Namecoin, and Litecoin, Peercoin does not have a hard limit on the number of possible coins, but is designed to eventually attain an annual inflation rate of 1%. There is a deflationary aspect to Peercoin as the transaction fee of 0.01 PPC/kb paid to the network is destroyed. This feature, along with increased energy efficiency, aim to allow for greater long-term scalability. With the same encryption algorithm as Bitcoin (SHA-256), Peercoin is 100 times more energy efficient. Transactions in the Peercoin network are faster and cheaper. If there were not fierce competition on the cryptocurrency market, Peercoin would probably have long since become one of the most important cryptocurrencies. But in 2014 and 2015, however, there were many other interesting innovations in the cryptocurrency market that outperformed peercoin in a number of important properties. In contrast to DASH, Peercoin could not offer anonymity and the transactions in Dogecoin were even faster and cheaper than those of Peercoin. PoS technology ceased to be an advantage of peercoin and PoS continued to spread to other cryptocurrencies. The interest of the users drew it to the side of the minings on the CPUs and GPUs, then to the side of the Smart Contracts and PPC began to get a little forgotten. The Peercoin Team believes that adapting blockchains for wide scale use only through on-chain transactions will negatively affect the decentralization level and security of the network over time, therefore we choose to develop the Peercoin blockchain as a base layer settlement network with a sole focus on securing all forms of value recorded into the chain. This can be accomplished through Peercoin's philosophy of preserving and maximizing decentralization (which increases security) by developing the majority of features and technologies on top of the blockchain, rather than directly into the blockchain protocol itself. Thus the Peercoin Team focuses on developing second layer protocols and sub-networks that can interact with the base layer blockchain to adapt it for wide scale use and improve functionality such as tokens, smart contracts and high speed low cost transaction processing. In this way, Peercoin will act as a secure and censorship resistant base layer for the future blockchain connected world.
Zebi is a young and innovative organization founded, mentored and managed by Oxford, MIT, Stanford, and IIT veterans and thought leaders from Silicon Valley with experience in Google, Uber, Amazon, Microsoft, and Oracle. Zebi specializes in providing Blockchain based offerings to governments and enterprises to leverage and protect their high value and sensitive data. India’s big data generation is increasing exponentially and is expected to reach 3 Zebibytes per year (Zebibyte = 1024^7 bytes) by 2020, driven by continued growth of internet usage, social networks, proliferation of smartphones, as well as the digital initiatives and structural reforms undertaken by the government. At the same time, incidents of data crimes such as data hacks, data leaks, data tampering, identity thefts are on the rise, which are costing Indian organizations and consumers more than $30 billion annually. Zebi specializes in providing blockchain based solutions to governments and enterprises to leverage and protect their high value and sensitive data. Zebi is one of the few enterprise grade product companies based in India offering best of the expertise of Silicon Valley at Indian prices Recognizing the need and opportunity to enable with technology the enforcement of data protection regulations, Zebi has created a Blockchain driven, unique and holistic solution to make high value and sensitive data readily available for legitimate use. Zebi safeguards data against hacking and tampering, while obtaining consent from individuals. The solution comprises of Zebi Chain™ to provide immutability to critical records, coupled with a central hub called Zebi Data Gateway which enables secure and instant data exchange through Data-as-a-Service (DaaS) APIs. Zebi’s innovative, proprietary solution set is one of the first in industry and is patent pending.
