stacking. In addition, UMI — a real blockchain platform capable of executing smart contracts of any complexity. Let us have a closer look at UMI abilities. Coins in UMI system are not frozen after joining the pool, unlike other systems, working with stacking. UMI — one of the young projects мейд at the intersection of decentralized money and digital assets, which attracts attention not only by its unique features, but also by its stated development plans. After refilling the wallet address, you can put your coins for stacking in two pools. In an ocean of cryptocurrency projects, it is difficult for investors to recognize promising services at an early stage of development, and it is precisely investments at this stage that allow you to get the highest returns. The difference of PoA from the favorite algorithms of Proof-of-Work (Bitcoin uses it) or Proof-of-Stake (Ethereum plans to switch to PoS) is that in the PoA-network there is no competitive race among miners or foragers for the right to be the first to make a block and get a reward. A user at any time can withdraw them and sell them. This is much higher than most other blockchains, including such popular ones as Bitcoin or Ethereum. These include various decentralized money services (DeFi). They remain in the wallet of the user, and no one has access to them, except the owner.Development. Smart contracts. UMI — it is a universal currency tool that allows users to make instant, safe, and free money transfers and to increase the value of the cryptocurrency by means of profitable stacking. UMI blockchain allows you to create a large number of specialized functional smart contracts, including those suitable for integration into e-commerce services or for launching decentralized autonomous organizations (DAO). The formation of blocks, and most importantly — sending them to the blockchain is done by trusted nodes — master nodes. Currently, UMI coins can be mined in two stacking structures (pools) — ROY Club and ISP Club.UMI blockchain ecosystem: second transfers, smart contracts and profitable stackingThe number of issued cryptocurrencies and digital tokens exceeded seven thousand. To do so, you need to make an individual purse in the UMI blockchain, to transfer a certain amount of UMI coins to your own address. UMI blockchain is based on http://trustcryptoreview.com/umi-blockchain-review/ Proof-of-Authority technology, a concept proposed by Ethereum co-founder Gavin Wood. This significantly increases network throughput. Transfers UMI network has the bandwidth of about four thousand five hundred transactions per second. In the UMI network, the master nodes — Authorized large nodes that meet stringent speed requirements. Rewards for stacking are accrued in twenty four hours.
