The public chain project Iost (Iost) announced the development roadmap for the second half of 2020, and Iost said it would comprehensively develop the defi ecology. Meanwhile, Iost will continue to make continuous efforts in the aspects of node partner plan, DAPP ecology, cross chain technology, landing application, compliance development, government enterprTypes of precious metalsise cooperation, community expansion, etc.

He also served as dmarket consultant for distributed market of virtual goods. This version of the cdva000 is officially launched to test the function of the first CDP KAP. Kava also said that it will support BNB's anchoring function test in the next cdp5000 test network version, with the main goal of testing kava's interoperability with external assets. As previously reported by Lianwen, the kavacdp4000 test network will also include the testing of bugs and other functions for the upcoming deployment, as well as the testing of governance functions (such as adding and deleting assets) and adjusting parameters (such as stabilization fees and liquidation fines).

The following investors include Bain Capital, coinbase ventures, dragonfly capital, blockchain capital, fintech collective, the box group and twosigma ventures. UMA view more announced the launch of mining activities for developers, planning to allocate 35% of UMA token supply, belonging to the community token distribution category, currently worth more than 250 million US dollars. Starting November 10, the risklabs foundation will pay 50000 umas (worth more than $300000) per week to developers responsible for casting synthesizers to distribute ownership of the agreement to developers based on the agreement. In order to increase the enthusiasm of liquidity providers to use the agreement, developers can keep the rewards or distribute them to users. This also means that developers can flexibly customize the liquidity mining program. Link note, UMA is a protocol used to build synthetic assets, and its governance token UMA can be used for system governance and Oracle dispute resolution.

Chainlink network is a distributed network of chainlink nodes, which directly transmits the use of specific data, API and various offline payment functions to smart contracts. With Chainlink, you can call one or more databases in a contract to query the data you need. The chainlink network consists of two independent parts, on chain and out chain, which must interact to provide services. The network is built in such a way that it can be upgraded, so it can replace its different components as better technologies and technologies emerge. The components on the chain of the network filter Oracle based on the measurement of the request of one party of the smart contract through the service level agreement SLA. Using these metrics, chainlink collects responses to SLA queries, sorts them using reputation and aggregation models, and provides the final aggregate results of chainlink queries that may be implemented into smart contracts. When you enter "interest rate" in the chainlink search box, you will see that there are more than 50 data streams to choose from. Copy and paste the required data into your smart contract. After database developers connect API with chainlink, they can get link token every time someone calls their database. The chainlink team is from smartcontract,

Meter integrates encryption philosophy and economic principles to build stable currency on such a theoretical basis. It will be connected with the physical world transparently; it will try to achieve trust without intermediary, just like bitcoin, and follow the basic economic principles of the "ternary paradox". Its goal is to realize three basic functions of money: value storage, unit of valuation and medium of exchange. In view of this stability, meter fixed its production cost, 1meter = 10kwh, and realized the relative stability of its value through hash computing power. In addition, it further realizes value stability through game mechanism and independent monetary policy. Meter takes advantage of the advantages of POW and POS, but also has its own characteristics. One advantage of this hybrid consensus is the fault tolerance of partitions. It does not require strong synchronization. When the network partition occurs, more than 1 / 3 of the committee members are offline, and the block production will stop. POW can continue to mine on the side chain. As long as the main chain network is restored, the pow chain will trigger the Committee re election and generate a new accounting cycle. Meter stability comes from a series of system designs, involving the transformation of electricity from the physical world into the currency of the virtual world, the establishment of a long-term consensus on the value of money by using the profit seeking behavior of miners and mining costs, the invisible and stable monetary policy, the hybrid consensus design of decoupling currency Issuance and bookkeeping, and the governance mechanism of reserve pool. Different from other stable currencies, it is not issued as a mortgage of US dollar and other legal currencies, nor is it generated by mortgage of Eth and other crypto assets. It uses the issuing mechanism of bitcoin for reference, and issues stable currency through the invisible anchoring of relatively stable commodities in the physical world. At the same time, people can participate in the issuance, use and governance of money without permission, which is a more pure practice of stable currency. Meter has put forward a completely different development path from Libra, which may go further. Metermeter view more announced that the network chainlinkchainlinkchainlink is a Oracle network, which solves the interoperability problem for the blockchain smart contract, and securely connects it to the offline data source, webapi and traditional bank payment system. Chainlink greatly enriches the application scenarios of smart contract, which can be applied in many industries such as finance, insurance and supply chain.

Defi's total TVL exceeded $8 billion for the first time, according to debank. The top five were maker (US $1.4 billion), AAVE (US $1.3 billion), curve (US $1.2 billion), synthetix (US $800 million) and year (US $Types of precious metals790 million).

Dharma announced that it would increase support for Dai on January 16 and move all Sai's deposit assets to Dai. Once Dai is added, Dharma will no longer support "Sai" deposits and withdrawals. This means that Dharma will no longer support Sai's deposits and withdrawals after January 16. Previously, Lianwen reported that the Dai system had been upgraded on November 18, 2019. So far, Dharma has been actively observing the migration of Dai, and continues to support the early version of Dai, Sai.
