Bitcoin is an electronic currency which is not in the hands of any financial institution or government. Instead, it uses peer-topeer software with cryptography. The public ledger is used to keep records of bitcoin transactions. And copies are kept on servers all over the world. Nodes are servers that anybody can create with their spare computer. Each transaction that is broadcast to the network by node-to-node and later shared between the nodes, forms an agreement reached via cryptography among nodes. At least every ten minutes, these transactions are collected together by miners in a collection called a block and forever added in the blockchain. The bitcoin account book serves as the final document of all transactions. Bitcoins can be stored in digital wallets which can be accessed via client software, as well as various devices and tools online.

The word travel's origin is probably lost to time. It's possible that the word travel originates from the Old French word called travail which means "work". Merriam Webster claims that travel's initial use was documented around the 14th century. The dictionary says that the word travel is derived in Middle English (which is tormenting struggling, toiling, or striving) as well Old French (which was toil). Work is employed in English to refer to the struggle. Simon Winchester writes in The Best Travelers' Tales (2004) that travel and travail are both derived from a prior time in the Roman torture instrument known as the tripalium. The modern travel experience can differ in difficulties based on the destination you choose. Mount Everest is a more demanding destination to travel. It is also a difficult destination to travel through. Amazon rainforest, extremely touristic activities, and adventure tourism are all difficult kinds of travel. Travel can also become difficult when you travel in an alternative way, like on a ship, by bus or even a bullock carts.
