About Polygon (Matic)
TokenPocket has supported Polygon mainnet (previously Matic network), so users can use Polygon through TokenPocket. Polygon is a protocol and a framework for building and connecting Ethereum-compatible blockchain networks. Aggregating scalable solutions on Ethereum supporting a multi-chain Ethereum ecosystem.

How to create Polygon ?
1.Open TokenPocket App, click the wallet name in the upper left corner to switch wallet, choose [Polygon], and then click [Add Wallet];

Definition of blockchain nodes
The blockchain node is a server for acting as a communication point that may perform different functions in a region. In the Internet, if all the data being run in a server, then this server is a node. So, the nodes in the blockchain network are equivalent to computers or server terminals tostore block data.

Classification of blockchain nodes
According to the degree of decentralization of the wallet, wallets can be divided into full-node wallets, light-node wallets, and centralized wallets.

A full-node wallet is to synchronize all data on the blockchain to the wallet, which will…

The last solution we’ll introduce is Rollup, which is recognized as the best Layer 2 solution currently. There are two apporoaches about Rollups: ZK Rollup (ZKR) and Optimistic Rollup (OR)

ZK Rollup (ZKR)
ZK Rollup uses cryptographic zero-knowledge proofs to ensure the security of the network and data. ZK Rollup separates calculation and verification. Funds are held by smart contracts on the main chain, and calculations and storage are performed on the off-chain. …

Airdrop token “phishing”

Recently, users’ve received airdrop tokens when they checked their transaction records. And it will be found that there is a link in memo line when click the transactions and noticed that the airdrop tokens can be exchanged for TRX. If users open the link and exchange airdrop tokens for TRX, their USDT will be maliciously approved, resulting in assets lost.

Side Chains
The essence of the side chain is to build a completely separate blockchain behind a simple side chain, with its own validator and operator, that has bridges to transfer assets to and from the main chain, and optionally snapshots the block headers to the main chain to prevent forks.

It is considered to be an scaling solution obtained at the expense of security to a certain extent. The snapshots can provide security against forks even when the validators of the side chain collude and try to fork out.

Advantage:
TPS improvement

Disadvantages:
1. Low consensus
2. Unknown dispersion of hashrate
3…

There are four approches for layer 2 scaling solutions. This chapter, we will talk about the first solution: State channels (The earliest solution)

Features:
Payment channel is a specific instantiation of a more generic concept called State Channels. State channel is a protocol between a fixed set of participants (often two) that want to transact securely between themselves off-chain, in case of payment channel specifically exchange money. Since transactions occur inside the channel, it provides good privacy. In addition, there is no network burden of the main chain, so the channel processing speed is faster, and only two transactions are provided…
