Polymarket on-line Bitcoin Lightning Network, instant charge, access to Spark protocol

On 8 July, Polymarket, the predictive market platform, announced its support for the immediate, self-custody charge through the Bitcoin lightning network, supported by the Spark agreement. Compared to the three to six blocks previously required to wait for confirmation, which would take approximately 10 to 60 minutes to fill the chain, the new scheme would achieve second-rate entry and lower the charge threshold and transaction costs. Spark was described as having been able to perform checks such as double-flower risk, handling fees and replace-by-Fee (RBF) at the time of the transaction, and to achieve "zero recognition" recording, while supporting the chain, the lightning network and the stable currency payment route without having to operate the lightning network nodes on the platform itself. Polymarket stated that this would further increase the efficiency of the use of funds by Bitcoin users and enhance their competitiveness with their competitors, Kalshi。
