On January 15, Grin, the main cryptocurrency network, was launched, which is based on the MimbleWimble protocol aimed at solving problems of scaling and privacy.

It is stated on GitHub that Grin is already supported by the decentralized Bisq exchange, the well-known mining pools of BTC.com and F2Pool, as well as other companies and crypto services.

Grin is an implementation of the MimbleWimble protocol, the creator of which is still unknown. Within the framework of this blockchain, there is no concept of addresses and the requirements for free space for data storage are minimized. Also, this blockchain promises to be fast and decentralized.

In addition to the high degree of privacy and scalability, Grin is distinguished by the fact that the generation of new blocks in the network of this cryptocurrency occurs every minute. The cryptocurrency is based on the CWCOO Cycle hash algorithm, which is resistant to hacking with the help of quantum computing.

According to the developers, within two years after the launch of the main Grin network, hard forks will be held regularly, aimed at countering ASIC miners who are threatening the ideology of decentralization.

It is noteworthy that the launch of Grin was not preceded by ICO or Premin, the development was conducted on a voluntary basis.

Bitcoin SV Blockchain to Undergo Reorganization

This happened due to the fact that some blocks were rejected by Bitcoin SV blockchain

Several blocks were rejected by the Bitcoin SV network after the addition, which caused the re-organization in the blockchain's history.

Almost each time someone is trying to produce a very large block on the BSV chain, there’s a reorg. Just an hour ago our Blockchair engine has witnessed a 3-block reorg (I think that's a record)! Blocks #578640–578642 got orphaned by a longer chain because they were too big

The large blocks, about which Zhavoronkov writes, are no longer displayed by the blockchain browser, since they are not part of the main chain in which they were located until a certain moment, until they were replaced by another chain, which eventually became dominant.

This is basically exactly the problem the BU gigabock testnet identified. At sizes > 100mb the mempools were so out of sync that blocks were basically transmitted as full blocks.

BSV had ONE 128mb block and it caused a six block reorg. On the BU testnet sustained 128mb blocks caused a total breakdown of the chain where there were so many reorgs that every node had a different view of the state of the blockchain.

Thus, Chris assumes that the problem is caused not by the malicious actions of the network members, but by its functional bug. 

This update is noticeable in the background of recent Bitcoin SV delisting campaign, which was started by the number of big exchanges as a reply to lawsuit by Craig Wright, BSV supporter, against anonymous critic.
