It contrasts with a futures market, in which settlement is due at a later date. Spot A contract or transaction buying or selling a cryptocurrency for immediate settlement, or payment and delivery, of the cryptocurrency on the market. Simplified Payment Verification A lightweight client to verify blockchain transactions, downloading only block headers and requesting proof of inclusion to the blockchain in the Merkle Tree. Sharding Sharding is a scaling approach that enables splitting cryptocurrency glossary of blockchain states into partitions containing states and transaction history, so that each shard can be processed in parallel. Selfish Mining A situation in which a miner mines a new block but does not broadcast this new block to the other miners. Segregated Witness A Bitcoin Improvement Proposal that aimed to fix transaction malleability on Bitcoin. In the past, when changing the “witness” information on blocks, it would change the transaction ID and its subsequent hash.

Private Key / Secret Key A piece of code generated in asymmetric-key encryption process, paired with a public key, to be used in decrypting information hashed with the public key. Pre-mine When some or all of a coin’s initial supply is generated during or before the public launch, rather than being generated over time through mining or inflation. cryptocurrency glossary They may be used for legitimate purposes, such as crowdfunding or marketing.

SegWit was aiming to fix this by segregating signature and block content a side effect of this change was smaller block sizes and the ability to support second layer solutions.
