[Cyber•Fund](https://github.com/cyberFund) is introducing a series of publications that provide an overview of some of the best speaker topics we’ve hosted at our [meetups](https://www.youtube.com/playlist?list=PLPWnfK03kxEDVJj4aPCdLDo--blBNm3iN). **Sami Makela** — a senior core developer currently working on the [TrueBit](https://truebit.io/) project — spoke about how TrueBit is being used to verify off-chain computations, and provides a “computational boost” of sorts to Ethereum based smart contracts.

_**TrueBit** is a system built on the Ethereum blockchain that conducts off-chain transactions._

# On-Chain Transactions
In order to run a smart contract the user must provide verified calculations. Each particular block includes transactions, and in turn each node conducts the transactions. If a miner does not function correctly, the block will be rejected. This model holds a few limitations, the most prominent of which is the limit of gas consumed for every block. This particular amount of gas can be insufficient to accomplish a given computational task, and drawn-out calculations are expensive on Ethereum. [TrueBit](https://truebit.io/) provides the user with more effective **off-chain solutions**.

# Off-Chain Computing
This form of computing begins calculating a square root. It often takes a great deal of time to calculate a square root with a smart contract. If these types of calculations take place off-chain, then an answer is immediately generated and can be used to automatically execute commands. The use of an ordered, linked-list in addition to off-chain calculating simplifies the overall implementation of data structures.

# TrueBit
The **TrueBit** project splits calculations into simpler steps; each of which determines the next one. This reduces the number of additional calculations for every new stage. TrueBit uses the following tools:

### Advanced JavaScript
#### WebAssembly

### Program Collection in WebAssembly
#### Empscripten

### Off-Chain Data Storage
#### IPFS, Swarm
