By providing a persistent, distributed, and append-only ledger, blockchains enable numerous applications such as distributed consensus, robustness against equivocation, and smart contracts. However, recent studies show that blockchain systems such as Bitcoin can be (mis)used to store arbitrary content. This has already been used to store arguably objectionable content on Bitcoin's blockchain. Already single instances of clearly objectionable or even illegal content can put the whole system at risk by making its node operators culpable. To overcome this imminent risk, we survey and discuss the design space of countermeasures against the insertion of such objectionable content. Our analysis shows a wide spectrum of potential countermeasures, which are often combinable for increased efficiency. First, we investigate special-purpose content detectors as an ad hoc mitigation. As they turn out to be easily evadable, we also investigate content-agnostic countermeasures. We find that mandatory minimum fees as well as mitigation of transaction manipulability via identifier commitments significantly raise the bar for inserting harmful content into a blockchain.}, keywords = {Bitcoin,blockchain,security,objectionable content,countermeasure}, tags = {mynedata,iop}, url = {https://www.comsys.rwth-aachen.de/fileadmin/papers/2018/2018-matzutt-blockchain-contents-countermeasures.pdf}, web_url = {https://ieeexplore.ieee.org/document/8360355}, publisher = {IEEE}, booktitle = {Proceedings of the First IEEE Workshop on Blockchain Technologies and Applications (BTA), co-located with the IEEE International Conference on Cloud Engineering 2018 (IC2E 2018)}, event_place = {Orlando, Florida, USA}, event_name = {First IEEE Workshop on Blockchain Technologies and Applications (BTA)}, event_date = {2018-04-17}, language = {English}, ISBN = {978-1-5386-5008-0}, DOI = {10.1109/IC2E.2018.00070}, reviewed = {1}, author = {Matzutt, Roman and Henze, Martin and Ziegeldorf, Jan Henrik and Hiller, Jens and Wehrle, Klaus} } @Article { 2018-scheitle-ccr-caa, title = {A First Look at Certification Authority Authorization (CAA)}, journal = {ACM SIGCOMM Computer Communications Review (CCR)}, year = {2018}, month = {4}, volume = {48}, pages = {10-23}, note = {https://www.net.in.tum.de/fileadmin/bibtex/publications/papers/caa17.pdf}, tags = {internet-measurements}, url = {https://ccronline.sigcomm.org/wp-content/uploads/2018/05/sigcomm-ccr-final163.pdf}, web_url = {https://ccronline.sigcomm.org/2018/a-first-look-at-certification-authority-authorization-caa/}, web_url_date = {2018-06-05}, DOI = {10.1145/3213232.3213235}, reviewed = {1}, author = {Scheitle, Quirin and Chung, Taejoong and Hiller, Jens and Gasser, Oliver and Naab, Johannes and van Rijswijk-Deij, Roland and Hohlfeld, Oliver and Holz, Ralph and Choffnes, Dave and Mislove, Alan and Carle, Georg} } @Article { 2016-fgcs-ziegeldorf-bitcoin, title = {Secure and anonymous decentralized Bitcoin mixing}, journal = {Future Generation Computer Systems}, year = {2018}, month = {3}, volume = {80}, pages = {448-466}, keywords = {Pseudonymity, anonymity, and untraceability}, tags = {rfc}, url = {https://www.comsys.rwth-aachen.de/fileadmin/papers/2018/2018-ziegeldorf-fgcs-bitcoin.pdf}, misc2 = {Online}, publisher = {Elsevier}, language = {en}, ISSN = {0167-739X}, DOI = {10.1016/j.future.2016.05.018}, reviewed = {1}, author = {Ziegeldorf, Jan Henrik and Matzutt, Roman and Henze, Martin and Grossmann, Fred and Wehrle, Klaus} } @Inproceedings { 2018-matzutt-bitcoin-content, title = {A Quantitative Analysis of the Impact of Arbitrary Blockchain Content on Bitcoin}, year = {2018}, month = {2}, day = {26}, abstract = {Blockchains primarily enable credible accounting of digital events, e.g., money transfers in cryptocurrencies. However, beyond this original purpose, blockchains also irrevocably record arbitrary data, ranging from short messages to pictures. This does not come without risk for users as each participant has to locally replicate the complete blockchain, particularly including potentially harmful content. We provide the first systematic analysis of the benefits and threats of arbitrary blockchain content. Our analysis shows that certain content, e.g., illegal pornography, can render the mere possession of a blockchain illegal. Based on these insights, we conduct a thorough quantitative and qualitative analysis of unintended content on Bitcoin's blockchain. Although most data originates from benign extensions to Bitcoin's protocol, our analysis reveals more than 1600 files on the blockchain, over 99\% of which are texts or images. Among these files there is clearly objectionable content such as links to child pornography, which is distributed to all Bitcoin participants. With our analysis, we thus highlight the importance for future blockchain designs to address the possibility of unintended data insertion and protect blockchain users accordingly.}, tags = {mynedata}, url = {https://www.comsys.rwth-aachen.de/fileadmin/papers/2018/2018_matzutt_bitcoin-contents_preproceedings-version.pdf}, web_url_date = {2018-01-07}, misc2 = {Online}, publisher = {Springer}, booktitle = {Proceedings of the 22nd International Conference on Financial Cryptography and Data Security (FC), Nieuwpoort, Cura\c{c}ao}, event_place = {Nieuwpoort, Cura\c{c}ao}, event_name = {Financial Cryptography and Data Security 2018}, language = {en}, DOI = {10.1007/978-3-662-58387-6_23}, reviewed = {1}, author = {Matzutt, Roman and Hiller, Jens and Henze, Martin and Ziegeldorf, Jan Henrik and M{\"u}llmann, Dirk and Hohlfeld, Oliver and Wehrle, Klaus} } @Inproceedings { 2018-dedin-energy-packets, title = {A new solution for the Energy Packet-based Dispatching using power/signal dual modulation}, year = {2018}, booktitle = {Proceedings of the Ninth International Conference on Future Energy Systems (ACM e-Energy '18)}, event_place = {Karlsruhe, Germany}, event_name = {Ninth International Conference on Future Energy Systems}, event_date = {2018-06-15}, DOI = {10.1145/3208903.3208931}, reviewed = {1}, author = {De Din, Edoardo and Monti, Antonello and Hagenmeyer, Veit and Wehrle, Klaus} }
