The Decentralized Identity for Smart Society 5.0 and Metaverse
What is Decentralized Identity Decentralized identity (DID) is a new method of identifying a person or digital assets. Contrary to traditional methods, where all information is centrally managed by an organization or a government, decentralized identity does not depend on a single centralized authority.The traditional way of identification The traditional identity has many problems such as accessibility, security, privacy … The decentralized identity (DID), on the other hand, uses data from many data sources which are managed by the data owners and only owners can prove their identity, decide which information to share or grant the access to a specific organization.

Their identities are represented by the public key and stored on the blockchain network.Users or holders: The data owners. Data will be managed by the user’s wallet (a key pair). Users can decide which information to share and prove their identity with their signature.Verifier: The company or organization that verifies user’s identity and grants access to users.

How to upgrade to UniChain version 2
UniChain will perform the hard fork to version 2 between October 20, 2021 and October 25, 2021 through the voting mechanism. UniChain has already contacted most of the current witnesses, the hard fork proposal will be broadcasted to the network on around October 20, 2021. If the proposal is accepted by most of the witnesses (⅔ witness agrees on the proposal), the network will switch to version 2. It is obligatory to all other nodes to update to a new version in order to keep the same chain. Nodes that run the old version will be separated from the network and may not sync from other nodes.How to update nodes to version 2Download full node and relay node packages from official repository: Full node, relay nodeMove new packages to unichain version 1 folder.

UniChain is about performing hardfork around Oct 20th, 2021
As previous announcement, UniChain will perform the hardfork version 2 between October 20th and 25th, 2021. The hardfork is done through the voting mechanism of witness nodes. UniChain will create a hardfork proposal and broadcast to the network. When 2/3 of the witness nodes approve this proposal, the system will be automatically switched to the 2nd version. Witnesses and users running the current version need to upgrade the software (full node, relay node) to the 2nd version by October 20th, 2021. Download the latest version here: Full node, relay node, wallet cli In case the software has not been updated in time, the nodes running the old version will be separated from the main chain and cannot synchronize with the others when the network has switched to version 2. To synchronize again, the old nodes need to delete data and run the full node again, depending on the configuration of the machine and the network, it can take from a few hours to a few days for the nodes to sync all dataNew feature in UniChain version 2 The fee structures When starting the UniChain network, the fee concept is borrowed from Tron network ei Energy, Bandwidth concepts in the fee model. We soon realize that those models are quite complicated and may not have a good user experience (for example users must freeze balance to get energy in order to deploy smart contracts …). We will simplify the fee model like other platforms such as Binance Sma...

UniChain hard fork version 2 features

In this hardfork version, some bugs and vulnerabilities will be fixed, the two big changes must count into are the fee structure and the future balance.Top Blockchain Platform in 2021 The fee structures When starting the UniChain network, the fee concept is borrowed from Tron network ei Energy, Bandwidth concepts in the fee model. We soon realize that those models are quite complicated and may not have a good user experience (for example users must freeze balance to get energy in order to deploy smart contracts …). We will simplify the fee model like other platforms such as Binance Smart Chain or Ethereum so that the transaction fee will be calculated for each user’s usages while keeping the free fee model (ei each user will have some free transaction in a day). The frozen balance operation is still available but for getting voting power only. The future balance This is a simple function but maybe useful for many use cases including the escrow or commitment. This feature allows users to send UNW coins to others users but specify the time that the coin is available for spent. The following command in cli wallet demonstrate the usage > sendcoin Um918G...
