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.
MOAC stands for the Mother of All Chains. It is a blockchain platform that supports transactions and data access. It is scalable. Sub-chains and smart contracts are compatible with MOAC. Decentralized apps and cross-chain connections are possible as well. MOAC is based on the Ethereum platform, and it uses a ERC20 currency. MOAC offers more including, A layered configuration structure, Asynchronous contract calls, Sharding solutions and Pluggable validation schemes. Transactions are processed through several consensus systems. The rate is 100 times faster than current blockchain platforms. Sub-chains increase concurrency rates up to 10,000 times. Sub-chains reduce cost and create a test environment. Cross-chain connections allow users and dApps to migrate to the MOAC platform without any knowledge. There’s also a decentralized file storage system. MOAC uses a Proof-of-Work system that allows miners to mine the main chain and sub-chains. Mining can be done from mobile devices. PoW algorithms deter third-party interference, including denial of service attacks and spamming. Sharding is another notable feature in MOAC. This is a method for allocating processing power. The amount of processing power given is proportional to the number of nodes in the network. Large blockchain shards are divided into groups of small shards that are fast. MOAC has lofty ambitions: it uses multichain architecture with microchains built on top of the MOAC base layer. It also plans to enable crosschain atomic swaps between blockchains like Bitcoin or Ethereum, just like Komodo does. Both intend to do so via sharding. The MOAC testnet launched November 2017, and the MOAC ERC-20 token and wallet were created in February 2018. Mainnet MOAC launched at the end of April 2018 with Ethereum support, and a mainnet explorer is available on the MOAC.io website. Sharding is due for a December 2018 release. Tokenized MOAC transactions occur on the base layer, and sidechains handle smart contracts. Sidechain creators determine their individual consensus model, so traditional models like Proof-of-Stake or Proof-of-Skill can be used, along with new hybrid models. MOAC aims to be the mother of all cryptocurrencies, and its ambitions are backed by one of the strongest technical teams in blockchain. Based in China, the team has experience in blockchain, enterprise IT, and more. MOAC is a Proof-of-Work algorithm whose token started as an ERC-20 token on the Ethereum network. This base layer supports tokenization using other consensus mechanisms. MOAC decentralizes block processing using microchains and a technique called sharding. Microchains are cross-compatible and can soon be made cross-compatible with other chains for atomic swaps. MOAC has a strong community mostly based in China, where it has a strong presence across social media. This community can build it into a strong dApp, tokenization, and exchange platform.
