Graphene: A New Protocol for Block Propagation Using Set Reconciliation
[chapter]
2017
Lecture Notes in Computer Science
Preserved Fulltext
We devise a novel method of interactive set reconciliation for efficient block distribution. Our approach, called Graphene, couples a Bloom filter with an IBLT. ...
For example, while a 17.5 KB Xtreme Thinblock can be encoded in 10 KB with Compact Blocks, the same information can be encoded in 2.6 KB with Graphene. ...
Conclusion We presented Graphene, a protocol that uses Bloom filters and IBLTs for efficient block propagation. ...

We evaluate the use of Invertible Bloom Lookup Tables and the Graphene protocol to decrease block propagation times and bandwidth usage of certain messages. ...
We look at topics such as automatic discovery of peers when a new node joins the network, bandwidth usage of a node, message passing protocols and storage schemas and optimizations for the shared ledger ...
A.4 Block Propagation using Graphene Graphene relies on the Set Reconciliation method described above to determine which transactions belong to a block. ...

For this purpose, we design and implement into Bitcoin a new prioritized data synchronization protocol, called FalafelSync. ...
To this end, several schemes have been proposed over the last few years to speed up the block propagation, most notably the compact block protocol (BIP 152). ...
A practical solution to prioritized transaction synchronization will most likely involve a combination of sophisticated algorithms for finding differences and new data-structures for reconciliation. ...

Multi-party set reconciliation is a key component in distributed and networking systems. It naturally contains two dimensions, i.e., set representation and reconciliation protocol. ...
To this end, in this paper, we propose the marked cuckoo filter (MCF), a data structure for representing set members. Grounded on MCF, we implement the MCFsyn protocol to reconcile multiple sets. ...
ACKNOWLEDGMENT The authors thank all the anonymous reviewers for their insightful feedback. ...

Our method uses partial proof of work, which does not function as a block, as a time standard with finer granularity. ...
In networks that adopt our method, the proportion of the attacker hashrate necessary for selfish mining was approximately 0.31479 or higher, regardless of the block propagation capability of the attacker ...
Furthermore, the use of communication protocols that leverage set reconciliation, such as Graphene [26] , can further reduce the bandwidth. Additionally, our proposed method can be used as needed. ...

Since almost every codeword is useful for the receiver to decode new transactions, Strokkur nodes do not require coordination, for example, to determine which transactions the receiver is missing. ...
We present Strokkur, a new transaction broadcasting mechanism that provides both low bandwidth overhead and low latency. ...
