Therefore, transactions can be reconciled by tracing along the directed graphs. The central service provider also leverages crypto-hashing to enforce the immutability of each executed transaction. For example, each transaction is cryptographically hashed and written into a block in the block chain. Each transaction refers to a cryptographic hash of a prior transaction and each block refers to a cryptographic hash of a prior block. Therefore, the executed transactions are cryptographically strong in that if a single transaction is altered, then the entire block of transactions including the transaction is invalidated. |

Three-layer color display using active LED dies
Over a flexible substrate are deposited stacked pixel layers including a bottom layer of LEDs forming blue pixels, a middle layer of LEDs forming green pixels, and a top layer of LEDs forming red pixels. Each LED die comprises an LED portion and an integrated transistor portion. Applying a voltage to a control terminal of the transistor portion energizes the LED portion. The pixels are substantially transparent, due to the LEDs being microscopic and the pixel areas being much larger, to allow light from the underlying layers to pass through. The three layers of pixels are aligned so that a combination of a single top red pixel, a single underlying green pixel, and a single underlying blue pixel form a single multi-color pixel. The different layers have transparent column and row lines. |

Film scheme for bumping
A bump structure with a barrier layer, and a method for manufacturing the bump structure, are provided. In some embodiments, the bump structure comprises a conductive pad, a conductive bump, and a barrier layer. The conductive pad comprises a pad material. The conductive bump overlies the conductive pad, and comprises a lower bump layer and an upper bump layer covering the lower bump layer. The barrier layer is configured to block movement of the pad material from the conductive pad to the upper bump layer along sidewalls of the lower bump layer. In some embodiments, the barrier layer is a spacer lining the sidewalls of the lower bump layer. In other embodiments, the barrier layer is between the barrier layer and the conductive pad, and spaces the sidewalls of the lower bump layer from the conductive pad. |
