    Abstract: It is proposed a device and method for finding nilcatenations, and proposes nilcatenation detection techniques, which can be applied to blockchains, and even constitute a proof of useful work, as the periodic removal of nilcatenations keeps a ledger size as small as possible. Banks and blockchains need to keep track of an ever-increasing list of transactions between the accounts owned by their users. However, as time goes by, many of these transactions can be safely “forgotten”, in the sense that purging a set of transactions that compensate each other does not impact the network's semantic meaning i.e. the vector Bt of amounts representing the balances of users at a given point in time t. Nilcatenation refers to a collection of past transaction vectors having no effect on Bt. Removing these transactions yields a smaller, but equivalent set of transactions.

    Abstract: A method self-adapts signal quality of non-audio data exchanged via an audio channel between a mobile terminal and a payment accessory. The method includes at least one iteration of the following acts: reception, by the mobile terminal, of a reference signal transmitted by the payment accessory; analysis, in the mobile terminal, of the received reference signal, the analysis delivering at least one item of information representative of the quality of the reference signal, referred to as quality information; transmission, by the mobile terminal to the payment accessory, of the quality information. In the above iteration, the roles of the mobile terminal and the payment accessory can be switched.
