A new cryptocurrency representing a hard-forked version of Bitcoin, different from it in the blocksize limits
Last weekend, the Bitcoin Cash network was attacked. During the attack the unknown hackers took advantage of the vulnerability of transactions' plasticity, as reported by the Chinese mining pool ViaBTC on their social network:
BCC network was under transaction malleability attack which changes txid. We've temporarily suspended withdrawal and your assets are safe.

Distributed database that is used to maintain a continuously growing list of records, called blocks
Transaction malleability is the ability of someone to change unconfirmed transactions without making them invalid, which changes the transaction’s txid (an identifier used to uniquely identify a particular transaction), making child transactions invalid.
Is the first decentralized peer-to-peer payment network that is powered by its users with no central authority or middlemen
The funny thing is that the problem could be fixed by the Segregated Witness protocol, which had to be activated in the Bitcoin network this month. The Bitcoin Cash supporters argued that SegWit was not so important as, for example, larger blocks, and the problem itself can be solved in other ways. Now these statements are the source for jokes for Bitcoin Cash haters:
You guys are a joke. Declining the solution to the very issues you now face. But thanks for buying the bcash.

That's funny. SegWit fixes that issue and you made fun of it for it not being an issue.

Just use #SegWit! Oh wait...

According to the updated information from ViaBTC, now the withdrawals suspended are resumed on the exchange.
