### Bugs/ Exploits

* From Crypto Briefing (9-11-2020):

"*A critical flaw in Bitcoin SV’s ElectrumSV wallet has led to widespread theft, according to user reports on social media. Developers disabled the vulnerable multisig feature in ElectrumSV 1.3.8 after reports of user losses."*

#### Reorgs

* According (18-4-2019)to Nikita Zhavoronkov of blockchain explorer Blockchair, Bitcoin SV has experienced a six block or more reorganization due to miner confusion or fighting; blocks 578640-5 were orphaned, perhaps due to the size of the blocks with number 578644 coming in at 128 mb which is known to cause reorgs or orphaned blocks; the network was down for 1.5 hours during the reorg.
* From BlockThreat (24-7-2021):

*"On July 8, 2021 BSV chain had reports of an ongoing 51% attack. The attack was reported to be coming from a miner going by the name ZULUPool."*

* From Bitcoin.com (5-8-2021):

*"Reports show that the Bitcoinsv blockchain suffered from a 51% attack on Tuesday, August 3, 2021, as the founder of Blockchair, Nikita Zhavoronkov explained the network endured a 100 block reorg “wiping out 570k transactions.”"*

## Technology

* Whitepaper can be found [insert here].

## Usage

* Twetch; a micropayment-based social network with (9-9-2020) an encrypted direct-messaging function that lets users send each other money in the chat.

## Coin Distribution

* From Coin Metrics #38 (18-2-2020):

*"Bitcoin SV (BSV) percentage of supply held by addresses with balance of at least 1/1K has remained relatively flat, outside of a significant dip in February 2019, and a sudden increase in June 2019. In August 2018, when BSV forked from BTC, these large addresses held about 26% of BSV supply. As of February 2020, they hold about 24%."*

* From a twitter thread by Adam Cochran (29-4-2020): In BSV 1250 addresses hold 55.6% of BSV

## Pros and Cons

### Cons

* From Bitcoin.com (20-12-2019) which is pro-BCH:

*"In the last two days there have been two critical posts published against the Bitcoin Satoshi’s Vision network (BSV). On December 17, Binance Research published an allocation mining report that analyzed the mining activities of BTC, BCH, and BSV and the research detailed that BSV miners are mining irrationally to protect their investment. The following day, the firm Bitgo published a report that disclosed it will be depreciating BSV because of the upcoming hard fork that aims to remove Pay-to-Script-Hash (P2SH) outputs."*
