Abstract

In this paper, we propose Garrison, which is a payment channel with watchtower for Bitcoin. For this scheme, the storage requirements of both channel parties and their watchtower would be O(log(N)) with N being the maximum number of channel updates. Furthermore, using properties of the adaptor signature, Garrison avoids state duplication, meaning that both parties store the same version of transactions for each state and hence the number of transactions does not exponentially increase with the number of applications on top of the channel.
