Expect some turbulence ahead for the Bitcoin network

In a few months, beginning 1 August 2017, there may be some turbulence ahead for the Bitcoin network.

Bitcoin Core full-nodes comprise more than 95% of the Bitcoin network and are susceptible to CVE-2017-9230. BIP 148 upgraded nodes would fix this security vulnerability.

Don't be scared though since this serious CVE bug and security vulnerability is being intensively reviewed by the technical community. If you run and rely on the most recent version of a Bitcoin Core full-node then you should be 99% safe (but for the 1% chance)!

Beginning 1 August 2017, nodes that enforce BIP 148 will reject any block from miners that do not signal SegWit readiness, along with any block that is built on top of a block that does not signal support.
