However,
for the time being, the
mechanism needed to implement the Sprite
micropayment channels makes use of functions that can not currently be executed in bitcoin script (but could be run on the ethereum blockchain).
The Lightning Network expands on the Bitcoin Blockchain's basic transaction functionality by providing a means
for users to execute smart contracts on the blockchain itself, providing
for a
mechanism for users to establish near - instant
micropayments without the need to offload transactions to a custodian, which makes small payments impractical because the fees might be more expensive than the transaction itself.
Through time - lock and hash - lock
mechanisms and a trust-less system wherein transactions can be committed while broadcasting to the rest of the Blockchain at a later time, users can send as little as 0.00000001 BTC, or 0.01 bits, without the need
for custodian fees (which can make such
micropayments impractical otherwise).
