Problems solved by technology

Computational outsourcing is very similar to sidechains. Truebit is a protocol that does not directly increase the throughput of the basic chain, but enhances heavy calculations outside the chain, thereby reducing the computational burden of the basic chain. It is usually used for collaborative computing, but it will Causing privacy and confidentiality data leakage

Embodiment Construction

[0030] When the inventor was conducting research on blockchain sharding, he found that the existing sharding schemes are all static sharding technologies, essentially sharding according to the account address space, that is, according to different sharding strategies, once the sharding network is determined Finally, within a sharding cycle, accounts between shards cannot be circulated with each other, and the account address is fixed in the current shard, and the flexibility of sharding is greatly reduced. Moreover, due to the randomness of the transaction itself, the transaction behavior cannot be well predicted, resulting in the existing sharding strategy unable to ensure that the sharding system is in an optimal state for a long time; at the same time, user behavior changes in real time, and cross-shard transactions inevitably occur. Compared with transactions within shards, cross-shard transaction operations are complex and inefficient, which reduces system transaction thro...

Abstract

The invention provides a block chain dynamic fragmentation method and system, supports different fragmentation strategies, provides a flow of an address slice changing operation, guarantees the atomicity of the slice changing operation through mechanism design, and belongs to the technical field of block chain expansibility research. Through address slice changing, the cross-slice transaction proportion between slices is greatly reduced, and the optimal state of the slice system is kept for a long time, so that the performance loss of cross-slice operation is reduced, and the transaction processing performance of the slice system is improved.

Description

technical field [0001] The invention relates to the technical field of block chains, and in particular to a block chain dynamic fragmentation mechanism. Background technique [0002] Blockchain is a large-scale tamper-proof distributed and open network ledger technology based on cryptographic algorithms, which makes it possible to transfer value conveniently and quickly in an untrusted environment, and is regarded as the cornerstone of building a value Internet. With the development of social economy, the blockchain has emerged with its advantages of multi-party participation, openness and transparency, non-tampering, effective traceability, flexible and programmable, etc. People gradually realize the potential of blockchain technology and gradually apply it. For industrial-level applications such as finance, settlement, and traceability, blockchain technology is expected to trigger fundamental changes in many industries. However, blockchain technology is currently facing s...
