Generally speaking, internet privacy primarily concerns the invisibility of users’ data information, such as their identities, behaviors, and activities.

Recently, the similarities and differences between Bitcoin and Ethereum regarding the issue of price self-limitation have also been discussed. Some further thoughts and analysis are recorded below for readers’ discussion and criticism. The issue of self-limitation is actually somewhat subtle. Ethereum also draws on Bitcoin’s method of dynamically adjusting transaction fees (miner fees) in its calculations. For Bitcoin, the miner fee = vBytes (transaction size in bytes) * fee/vBytes (fee rate denominated in BTC); for Ethereum, the gas fee = gas (amount of computational resources consumed by instructions) * gas price (denominated in ETH). Therefore, on the surface, there doesn’t seem to be a problem with whether the fee rate or gas price is denominated in BTC, ETH, or USD. From the perspective of supply and demand economics, if the pricing currency relative to fiat currency is such that the expected fee income for miners (converted to fiat currency value) is just their cost (denominated in fiat currency) plus a reasonable profit, they can lower the fee rate (fee/vBytes or gas price) to maintain stability of the product of vBytes * fee/vBytes or gas * gas price relative to fiat currency. ...

The discussion in this article is not about using blockchain as a voting technology to fulfill certain voting requirements in the external world, such as conducting elections for a state governor in the United States on the blockchain or creating prediction markets where people can vote on whether the US will default on its debt or reach an agreement at the last moment to avoid default. These examples merely utilize blockchain to facilitate voting on external matters. The focus of this article is on the issue of decentralized organizations conducting on-chain voting themselves, which may involve a blockchain-based DAO voting on governance proposals or even governing the blockchain itself. ...

This way, the problem of poverty can be solved in one fell swoop. People will no longer worry about their basic needs and can dedicate their time to more meaningful work. ...

Bitcoin rebounded above $27,000 overnight. Children’s Day is approaching, but it seems like a difficult time for U.S. President Biden.
