Security audit of the Bitcoin SV node software

In late 2018, the Bitcoin SV implementation engaged leading security firm Trail of Bits to conduct a security audit of the Bitcoin SV Node software. The audit various issues, with 3 given a high-risk rating due to having a medium severity denial of service impact but a low difficulty to exploit.

The Bitcoin SV team did not itself cause the vulnerabilities but likely inherited them from the Bitcoin Core and Bitcoin ABC software implementations. In January, the Bitcoin SV team responsibly disclosed these vulnerabilities to the competing Bitcoin Core, Bitcoin Unlimited, Bitcoin ABC and Bitcoin XT teams. The Bitcoin SV Node team patched the vulnerabilities in its Feb 11 release. According to industry best practices, public discussion of the nature of the vulnerabilities was embargoed until March 1 to give the other Bitcoin node teams time to update their software.

We believe this is the first time in the history of Bitcoin that any Bitcoin node software has been the subject of a comprehensive security audit. The effort demonstrates Bitcoin SV is serious about its mission to help Bitcoin grow up and professionalize and become the choice for enterprise adoption.

BSV Application developments

Chart of OP-RETURN data by @cryptoguzzle

This week’s Satoshi Shout Out goes to Twitter user @cryptoguzzle  who showed us that real world usage on the BSV chain is accelerating.  He did so by creating a chart that illustrates growth of the BSV network since it raised the OP_RETURN data size limit.  He stated “Expect miners to start getting nice tx fees. Not worried about halvenings”.


The larger OP_RETURN data size limit continues to ignite creative explosions on BSV.  Mysterious Bitcoin developer _unwriter recently introduced Bitstagram. The world’s first Bitcoin Native photo app lets you take a photo on your mobile phone and upload it to the BSV blockchain for a small fee payable in BSV, using Money Button.  The application has also now enabled tipping of photos you like.  Look at what people have been uploading by visiting
