Nigerian Attorney General Has Sent Bitcoin Bill to National Assembly

In an effort to cleanse the digital space, the Nigerian government is working on e-money regulation, which will bring clarity to the regulation of the bitcoin industry in the country. The country’s justice minister, Abubakar Malami, said in a statement on Tuesday that the Ministry of Justice has submitted the bitcoin bill to the National Assembly, which, if approved, would provide a legislative framework for all digital currencies in the country. “It is expected that the bill will prepare Nigeria for emerging things such as digital cash, bitcoin and e-money,” Malami said.

So far, Iran’s Ministry of Industry, Mining and Trade has issued more than 1,000 operating licenses for cryptocurrency mining farms. Subsidized electricity prices in Iran have reportedly led some miners to flock to the country. To support permissioned cryptocurrency mining, Tavanir said it plans to cut miners’ electricity prices by up to 47 percent during periods of peak electricity usage.

Masayo Amamiya, deputy governor of the Bank of Japan, said that the Bank of Japan currently has no plans to issue a digital currency, but will consider the idea.

Gavin Wood wrote an article in response to the questioning of the avalanche protocol: the avalanche protocol is neither secure nor scalable
On July 28, a member of the Avalanche Protocol collected some questions about Polkadot within the Avalanche Protocol community and posted them on the Polkadot Riot official group. The specific questions involved Polkadot’s scalability, slot mechanism, and cross-chain performance .

Gavin Wood, the co-founder of Polkadot, responded to this matter, saying that the so-called subnet security of the Avalanche protocol is completely different from the shared security of Polkadot. How about a performance comparison. In effect, the Avalanche protocol acts like a centralized universe, with overlapping sets of elected validators acting as subnetwork security. This will lead to a great disparity in the security of the various chains in the entire system. Cross-shard attacks are possible because messages from one (less secure) chain can cause state transitions on another (more secure) subnet. In this way, the security of the entire network is equivalent to the chain with the worst security. As with the Cosmos problem, any solution that attempts to design a central area to enforce sensitive logic will hit a scalability bottleneck and degrade some chains into second-class citizens whose state transitions cannot be trusted. No matter which chain the program is executed on, it has the same level of security guarantee. This is a scalable system. To sum up, the avalanche protocol is neither secure nor scalable.
