IOTA is a distributed ledger for the Internet of Things. The first ledger with microtransactions without fees as well as secure data transfer. Quantum proof. IOTA is a ground breaking new open-source distributed ledger that does not use a blockchain. Its innovative new quantum-proof protocol, known as the Tangle, gives rise to unique new features like zero fees, infinite scalability, fast transactions, secure data transfer and many others. IOTA is initially focused on serving as the backbone of the Internet-of-Things (IoT). IOTA is a cryptocurrency that has no transaction fees and requires no miners in order to process transactions. It does, however, require some computational power to submit a transaction, making it perfect for machines to use as a currency and distributed communication protocol for the Internet of Things “IoT”. The main purpose of IOTA is to solve some of the major problems with Blockchain technology, the main one being that the bigger the Blockchain (such as Bitcoin), the slower, more expensive, and also more restricting it is to actually transfer funds. Another issue with the Blockchain is size, as more and more Blocks are added, the longer the Blockchain gets, and therefore the less amount of computers are able to mine it. Right now BTC is over 150GB long, and so is ETH. If this size increased tenfold, very few computers would be able to mine it at all. Making them relatively centralized (the top 2 Bitcoin mining pools own about 56% of hashing power).
Aelf is the versatile business blockchain platform powered by cloud computing and the central nervous system for businesses, transforming the way they deliver their services. By laying out the fundamental blockchain infrastructure, Aelf enables businesses to focus on building up their own dapps on their own chains with minimum effort. Acting as the master key, Aelf unlocks the potential for inter-business communication and collaboration using cross-chain efficiency. Incorporating modern technologies such as cloud nodes and parallel processing, Aelf is the blockchain system that achieves secure transactions at commercial scale. Aelf is one of the cryptocurrencies that is attracting crypto enthusiasts following its massive commercial adoption initiative. The coin seems to be leading on the technology front with higher blockchain efficiency, which is why it's also anticipated to be the Linux of Blockchains. aelf is an operating system for blockchains which can be customized by their respective users. Its cryptocurrency is denoted by the symbol ELF, with a total supply of 250 million ELF. It was launched on 21 December, 2017 on multiple exchanges in China without any ICO and instead got private investors on board. This ensured better compliance as KYC was done for all investors with most of them being accredited, with a good track record in token investment. Aelf was developed by Ma Haobao, who is also the CEO of Hoopox. The team is backed by a strong advisory board which includes Michael Arrington (CEO of TechCrunch and founding partner of FGB Capital). The team says it is working on unleashing the blockchain’s potential into mass applications and industries. aelf is now working with Innovation Alliance for increasing the acceptability of blockchain technology which will ultimately increase adoption of aelf’s blockchain. The team is focussed to develop aelf to improve other chains in the ecosystem by providing a template and infrastructure for interaction between the sidechains. Aelf also has a rewards system – Candy. With the Candy rewards system, you earn points, convertible for ELF, by accomplishing simple, daily tasks. Tasks include liking and replying to aelf tweets, inviting people to the Telegram channel, and other promotional activities. ELF are currently ERC20 tokens. As such, you can store them in any wallet with ERC20 support like MyEtherWallet or Exodus. The Ledger Nano S is also a great option if you’re interested in additional security. Aelf is a relatively new competitor in the dapp platform race but already has solid support from large investment capital firms. The project is utilizing resource separation through side chains and a unique governance model to build an entire blockchain operating system.
