Nevertheless, this ability comes with the cost of storing a large (distributed) ledger, which has become unsuitable for personal devices of any kind. Although the simplified payment verification (SPV) clients can address this storage issue, a Bitcoin SPV client has to rely on other Bitcoin nodes to obtain its transaction history and the current approaches offer no privacy guarantees to the SPV clients.\n  This work presents $T^3$, a trusted hardware-secured Bitcoin full client that","authors_text":"Adil Ahmad, Aniket Kate, Byoungyoung Lee, Duc V.
